In 1982, it was decided to change the time table for the ACFM meetings. Instead of having
one main meeting in July dealing with most of the stocks, with an additional minor one in
November taking care of a few stocks, the work has now been more equally divided between the
two meetings, one "in mid-May and one in late October/early November.
The time table of the assessment working groups had to be changed accordingly, and the advice
on different stocks has been distributed between the two meetings, taking into account
various factors such as the deadlines set by the management authorities for receiving advice,
timing of surveys, and collection of other scientific data, etc.

1988CRRReport of the ad hoc Study Group on "Environmental Impact of Mariculture"
154
3/16/2021 12:37 PMSøren Killerup Larsen
Following the adopted Resolution CR 1985/2:37 (73rd Statutory Meeting of ICES), CR
1986/2:36 (74th Statutory Meeting) an ad hoc Study Group on the "Environmental Impacts of
Mariculture" was established in order to: (a) delineate the dimensions of the problem, and (b)
recommend a course of action which will lead to a development of criteria and to a standard
system of monitoring and reporting." Membership to this ad hoc ICES Study Group was assigned
during 1986 with experts nominated from 11 member countries. The Study Group worked by
correspondence and met in Hamburg (Federal Republic of Germany) between April 7 and 9,
1987 to prepare the report. The environmental issues addressed include (a) our present
understanding of the effects of mariculture on natural microbial communities and on the
possible spread of pathogens, (b) the possible changes in the natural populations of marine algae
(phytoplankton and macroalgae), (c) the influence of sedimentation on the benthos, (d) the use
of chemicals in mariculture, (e) site selection criteria to minimize environmental effects, and
(f) the state of the art in developing predictive models of mariculture impacts. Further
chapters discuss environmental regulations (as applied to mariculture situations) in various
member countries, the need for improved feeds and feeding strategies, and the possible
beneficial effects of mariculture. Finally, a number of recommendations are formulated, related
to research needs to assess and minimize environmental impacts. Considering the increasing
environmental issues that are emerging with the expansion of the mariculture industry, the
establishment of an ICES Working Group on "Environmental Impact of Mariculture" is proposed
and the terms of references for such a Working Group are presented. Country reports are
presented in Appendix 1 and an extended literature list is included in Appendix 3.

1988CRRTHE STATUS OF CURRENT KNOWLEDGE ON ANTHROPOGENIC INFLUENCES IN THE IRISH SEA
155
3/16/2021 12:52 PMSøren Killerup Larsen
At its meeting in March 1985, the UK Marine Pollution Monitoring
Management Group (MPMMG) agreed that a review should be undertaken of 'the
state of knowledge on the Irish Sea in relation to the impact of pollution,
monitoring information and monitoring needs'. Some other guidelines
were also laid down which supplemented and, in one important way, changed
these terms of reference. The review was not to consider radioactive
pollutants since a separate Monitoring Management group has responsibility
for those. Contributors were to be from the UK only in the initial MPMMG
study, but from the outset the intention was to expand that review into
the present international study by including major inputs of text and data
from the Irish sources and via further review by a range of ICES Standing
Committees and Working Groups. The review was to be structured along the
guidelines recommended by Bewers et al. ( 1982) for the preparation of
regional assessments, which had the effect of broadening the terms of
reference to include not only pollution but past, present and prospective
anthropogenic effects on physical oceanography, pollution and biology. No
specific deadline was laid down but it was suggested that the first draft
should be available in about a year.

3/16/2021 1:22 PMSøren Killerup Larsen
The Working Group discussed in detail the working papers on the
effects on assessments of age- dependent mortality and discards.
It was apparent that, in both cases, there were discrepancies between
the theoretical expectations of the effects of these fac tors
on short- term forecasts and the results of practical tests
using real data. The theoretical studies had also not covered all
ramifications of interest. The Working Group decided to undertake
further investigations of these aspects. The techniques required
for the study of the effects of age- dependent natural mortality
and of discards are very similar, both theoretically and practi cally,
for both short- term and long- term assessments. It was,
therefore, decided to organize both the investigative work and
the report along these lines rather than on the basis of the
topics distinguished in the terms of reference. The report of the
work on short- term aspects is , therefore, in Section 2, and that
on long-term aspects in Section 3.

3/16/2021 1:36 PMSøren Killerup Larsen
The Advisory Committee on Marine Pollution (ACMP) was established
by the International Council for the Exploration of the Sea with
the task of formulating, on behalf of the Council, scientific advice
on marine pollution and its effects on living resources to
the Member Governments and to Regulatory Commissions. In its
work, the ACMP considers, among other things, the results of work
carried out in relevant ICES Working Groups (which also report to
their respective Standing Committees during the annual Statutory
Meetings). It is a firm procedure within the Council that reports
of other subsidiary bodies concerned with pollution pass the
ACMP.
The ACMP consists of a number of scientists acting when they
work as Committee members - in their personal capacity as scientists,
responsible only to the Council. The membership of the
Committee is such that it covers a wide range of expertise related
to studies of marine pollution. The members do not act as
national representatives. The 1988 membership of the Committee is
found on page 1.

3/16/2021 2:27 PMSøren Killerup Larsen
High quality measurements, together with an understanding of the associated
uncertainties, are essential for any scientific activity. Measurements provide
both an initial inspiration for a theory or model and, separately, a test of
its validity. Oceanographic measurements are additionally precious, being both
difficult and expensive to obtain, so the extra efforts to minimize the
potential for errors and to extract the maximum information from the
measurements, commensurate with their quality, are judicious. To achieve these
aims discussion sessions on data processing procedures and techniques are
invaluable; with the bonus that the papers, if published in one volume, will
provide a useful reference source both for novices and those not directly
involved in the data processing.

Through a combination of discussions, formal presentations and practical trials, the ICES
workshop held on board U/F Argos from 16-23 April 1988 considered the methodology of fish
disease• surveys. Particular emphasis was placed on assessing and updating the proposals of
the 1984 workshop in the light of four years of practical application. Substantial differences
still exist regarding the pathological conditions that are monitored and regarding diagnostic
interpretations, particularly when diseases occur at low levels. The major source of sampling
variability still existing was identified as the difficulty and reliability in detecting light cases
of disease (particularly lymphocystis). For ICES reporting purposes it is recommended that
only a restricted number of disease conditions be included and that, to improve reliability of
data for international comparison, results below clearly defined levels of disease severity should
be excluded.

The sediments offer a tremendous potential for the follow-up of the relative changes in the
concentrations of the inorganic and persistent organic contaminants in the marine environment.
Concentrations of harmful substances in water are known to be variable, depending on water
exchange, season and hydrographical factors, while concentrations in biomaterial depend,
among other things, on species, tissue type, age of the specimen, and the migration habits of the
species. In peaceful net sedimentation areas, the sediments represent the local hydrodynamic
regime, integrating the changes in the concentrations of persistent substances over a period of
time, the length of which depends on the sedimentation rate. While the rate of sedimentation
depends on the season, it has a great tendency to remain constant over the years.

This report gives an account of the results of the first step of the ICES/IOC/OSPARCOM Intercomparison
Exercise on the Analysis of Chlorobiphenyl Congeners in Marine Media. Results were received from 62
laboratories. An encouraging agreement has been achieved, with standard deviations for reproducibility of
1.11-1.12 for all CBs except CB 52 for a group of 47 laboratories. The optimization procedure of the gas
chromatograph (GC) was experienced by many participants as a valuable learning process. This optimization
of the GC conditions has led to a better level of agreement in comparison with former intercalibration
exercises on CB analysis .
Difficulties were experienced with the identification of the linear range of the electron capture detector and
bringing the unknown solution within this linear range. Results based on peak heights showed a better
reproducibility than results based on peak areas. The separation of CBs 28 and 31 was the most difficult one.
Only 28 laboratories were able to achieve a separation of these two CBs.
It is concluded that the second step of this exercise may be organized now. This step will involve, in
principle, an analysis of a cleaned-up blubber and a sediment extract.

At its meeting in Copenhagen in 1987, the ICES Working Group on Marine Sediments in Relation to
Pollution (WGMS) decided to distribute a questionnaire to determine how many laboratories would be
interested in participating in an intercomparison exercise on the determination of trace metals in small
amounts of suspended matter. According to the responses to the questionnaire, 60 laboratories were
interested in participating in such an intercomparison exercise, although several of them expressed conditions
for their participation. Later, a further five laboratories expressed interest in participating.
At the WGMS meeting in Savannah in 1989, it was agreed to carry out the first phase of a sequence of
intercomparison exercises on the determination of trace metals in suspended particulate matter. Jens Skei,
on behalf of the Norwegian lnstitute of Water Research, accepted the invitation to organize this first phase
of the intercomparison exercise.
The laboratories were asked to perform a preliminary exercise using their own standard reference material,
certified for trace metals, or any other well-characterized material. They should we'igh out a minimum of
three sub-samples in the range l - 5 mg, and analyze them for the metals for which certified values exist.
Once the laboratory had achieved the ability to analyze such small samples, they should notify the
coordinator and request the intercomparison material. The deadline for this preliminary exercise was set at
30 June 1989.

Clearly then, the strategy of the Study Group needed to be aimed at clarifying conceptual ideas and developing
theory rather than providing an up-to-date review of the field. Such objectives are often finaJly achieved
by individuals rather than by group discussions so the tactics of the meeting were to encourage, provoke,
or annoy individuals or small groups into attacking these needs. This was done firstly by group discussions
of the background and problems of recruitment mode11ing research. These are reported in Section 2.
Secondly, by splitting into smaller "think tanks" to address the problems in more detail. The reports of these
groups were all very useful, particularly in the elucidation of concepts, and are reported in Section 3.
Finally, individuals were encouraged to submit protypes of models, etc., that they hope to develop further,
or thoughts on concepts. These are reported in Section 4. This section is the responsibility of individuals
rather than a consensus view of the problem, but should provide ideas for the future and perhaps some
contributions to the proposed ICES Mini-Symposium for 1991 on "Models of Recruitment Processes
Relevant to the Formulation of Research Strategies".

This report has been prepared as a result of discussions in the Fisheries Acoustics Science and
Technology (FAST) Working Group ofthe International Council for the Exploration of the Sea (ICES).
Following discussions in Seattle, United States in 1987 and Ostend, Belgium in 1988, a questionnaire
on survey and data analysis practices was circulated to the working group participants. Replies were
received from Canada, Denmark, Finland, France, Iceland, Norway, Poland, Scotland, Sweden and
United States. The responses were compiled, presented, and discussed at the working group meeting
in Dublin, Ireland in 1989 (Simmonds, 1989). Further discussions were held in Rostock, Germany
in 1990 and it was decided to prepare a report to review acoustic survey and design procedures for
abundance estimation and to recommend a number of suitable acoustic survey procedures. This
report was prepared throughout 1990 and 1991, and a draft was presented and discussed at the
working group meeting in Ancona, Italy in April 1991 and at the statutory meeting in La Rochelle

3/23/2021 12:21 PMSøren Killerup Larsen
Under the auspices of the International Council for the
Exploration of the Sea (ICES), two Atlantic Salmon
Scale Reading Workshops were held in the Marine
Laboratory, Aberdeen. The first Workshop, in 1984,
produced a comprehensive guide to the collection and
interpretation of Atlantic salmon scales and the second
Workshop, in 1988, amended a number of these guidelines
in light of the experience which had been gained in
their use. The second Workshop also established guidelines
for computerized scale reading and developed new
parameters for stock identification. Because some of the
problems which had arisen in the interval between the
two Workshops could not be immediately resolved, a
number of research recommendations were added to the
list which appeared in the first Workshop report.
This report presents these guidelines, the new parameters
for stock identification, and the research recommendations.

The ACMP report addresses the questions posed to ICES by the regulatory Commissions of the Helsinki, Oslo and
Paris Conventions as well as other issues considered relevant by the ACMP. The Executive Summary that follows
this overview provides a summary of the report, under three sub-headings, for the Oslo and Paris Commissions
broadly corresponding with the groupings under which they record their requests, and a single sub-heading relating
to the requests specifically raised by the Helsinki Commission. There is an additional sub-heading for all
Commissions relating to items of interest which do not form part of any request.
The Executive Summary is followed by a more detailed report on the progress made in relation to the specific
questions raised by the three Commissions. This is intended to direct the reader to the sections of the report likely
to be of most interest in relation to a particular question.
It will be noted that in a number of cases the advice or information goes beyond that specifically requested by the
Commissioos. This additional material is provided, in part, simply for the sake of completing the picture so far
as it is practicable at this point in time. As such, it will be of benefit to the wider audience within ICES that ACMP
is also expected to advise. It is, however, hoped that the regulatory Commissions will find this material of interest,
since it is directly related to the question they have raised.

Item a) of the terms of reference refers to the question
of how various closures can affect stock assessments
through catchability changes or otherwise. Such closures
include closures of areas or limitations of the time
periods when fishing is permitted.
It is quite obvious that if only aggregate measures of
effort or CPUE are available, then resulting catchability
estimates can be quite badly biased. For example if
CPUE values have been calculated in aggregate form
before the closure of an area with high catch per unit of
effort, then the closure of this area may lead to a severe
underestimate in the CPUE estimates after the closure
takes effect. Similar concerns apply to temporal closures.

Ecosystem effects of fishing activities may occur at all
scales of space and time. Although a clear distinction
between local, regional, and North Sea-wide effects cannot
always be made, the global approach taken in this report is
inappropriate for consideration of some more local
ecosystem effects, both of fishing and other human
activities, which will be considered in regional reports.
Fisheries exploit species against the background of a
variable environment which is a major source of perturbation
to the system. The effects fisheries cause should
thus be viewed as one of several anthropogenic interactions
in a non-equilibrium system.

202
3/26/2021 12:28 PMSøren Killerup Larsen
Mariculture inevitably means that marine animals are grown in what are relatively, at least, intensive
conditions. Under such conditions disease is an ever present hazard and opportunist
pests, competitors and fouling organisms are often presented with ideal conditions. When the
first line of defence, good husbandry, fails operators are, as are all intensive animal culturists,
driven to other means of control.
It should be emphasised at an early stage in this report that "chemicals" employed in mariculture
may be of two types i) hygiene products for disinfection or for "environmental control"
e.g. antifouling agents for fish cages and ii), much more important, medicinal products, divided
into chemotherapeutic agents for therapy or prophylaxis of disease and act on the invading organism
and pharmacological drugs which act on the target animal. The discussion of the use of
the latter inevitably involves the use of terms and abbreviations which may be unfamiliar to
readers from outside the specific field. Appendix 1 provides a short list of terms and abbreviations
to aid understanding.

There is a growing perception among scientists and the
general public that human use of the marine environment
may have led to marked and widespread changes in the
North Sea ecosystem. Of these activities, fishing has
received considerable attention as an agent for change.
In recent years an increasing amount of information has
been collected, indicating that some fisheries are likely
to impose a considerable mortality on a variety of nontarget
species, including fish, benthos and marine mammals.
It is thus probable that fishing has led to the local
extinction of individual species, to habitat alteration, and
to some changes in the structure and functioning of the
ecosystem.

1/2/2021 11:46 AMSøren Killerup Larsen
Assessment of individual age through the use of calcified structures (scales, otoliths,
opercular bones, fin rays, etc.) has been proven to be very useful in assessing the status
of any fish stock. According to Panfili et al. (2002), data on age and growth of fish are
essential for understanding vital traits of species and populations (e.g. lifespan, age at
recruitment, age at sexual maturity, reproduction periods, migrations, mortality) and
the study of population demographic structure and its dynamics (e.g. age-based stock
assessment). The age profile of a fish stock can be indicative of its general “health”, as
one will expect to see evidence of a broad range of ages in a healthy population. A lack
of young fish may indicate recruitment failure, which will have repercussions in future
years, while a lack of older fish can signal overexploitation of the stock. Fisheries scientists
are especially concerned with the dynamics of exploited populations, with the
view to providing advice about the sustainable harvesting of the resource. In the ICES
Area, this task is generally focused on providing a quantitative assessment and forecast
on a stock, with age data at its core. Hilborn and Walters (1992) pointed out that the
“aim of such studies is not only to assess the state of stocks and fisheries relative to
historical states, biological reference points or management targets, but also to evaluate
the consequences for both fish stocks and fishermen, of alternative management scenarios.”
Therefore, it is clear that reliable age–length data are important for the management
and sustainable exploitation of fish stocks. The need for reliable data is especially
acute in times when stock levels are low and errors in predictions can have devastating
effects on the resources.

For a number of reasons it is very desirable to determine year class

In recent years, therefore, there has been an increase of international -·
interest in young fish surveys; largely because of the need for earlier
and more accurate forecasts of year class strength in relation to management

1977CRRTHE ICES COORDINATED MONITORING PROGRAMME IN THE NORTH SEA
58
4/13/2021 12:34 PMSøren Killerup Larsen
In 1971 ICES established a Working Group to examine the state of pollution
in the North Sea. One of the main tasks undertaken by that Working Group
was the conduct of a baseline survey of levels of contaminants/pollutants
in fi~h and shellfish taken from the North Sea. This survey was conducted
in 1972 and the results were published by the Council in Cooperative
Research Report, No.39 (1974). The Working Group, in its report, considered
that the results of the baseline survey showed the North Sea was not
seriously polluted, and that the only areas where the results gave any justification
for monitoring on a continuous basis were the coastal margins and
the Southern Bight, Kattegat and Skagerrak areas. Much of the necessary
work in these areas was already being conducted/com.missioned by national
authorities; therefore, rather than initiate a further special international
program.me, it was decided that a review of existing monitoring program.mes
should be undertaken, with a view to deciding which of these would produce
data relevant to an ICES coordinated monitoring effort in the North Sea,
and whether or not extra work should be com.missioned in particular areas.

1977CRRASSESSMENT OF HERRING STOCKS SOUTH OF 62°N

4/13/2021 11:58 AMSøren Killerup Larsen
In this volume the report resulting from the meeting of "The North
Sea Herring Assessment Working Group" in 1973 and those from the
meetings in 1974 and 1975 of the new group set up to succeed it -
"The Herring Assessment Working Group for the Area South of 62°North -
are presented. The purpose of each of these meetings was to provide
the Liaison Committee of ICES with advice, for transmission to the
North-East Atlantic Fisheries Commission on the state of, and
suggested management action for, pelagic stocks in the area south
of 62°N. The increase in the number of stocks which these Working
Groups have been required to assess in succeeding years illustrates
the expansion which has taken place in recent years in the exploitation
of pelagic resources in the area within which NEAFC is
responsible for fish stock management. The reader of these reports
will be able to form his own judgment of how effectively that
management function has been discharged.

A baseline survey of pollutant levels in fish and shellfish from the North
Sea was conducted under ICES auspices in 1972. The results of this survey
were published by the Council in Cooperative Re sea r ch Report, No.39
(1974). The report concluded that a lthough the North Sea was not s eriously
polluted there was a need for continued monitoring in certain areas, particularly
the coastal margins, the Southern Bight , Kattegat and Skagerrak
areas. Since most of the countries concer ned were already carrying out
routine measurements for their own national purposes it was considered
likely that information could be pooled from these various program.mes and
welded into a Coordinated Monitoring Report on the areas indicated to be
worthy of continued study on an international basis.

88
2/18/2021 10:57 AMSøren Killerup Larsen
Because of a systematic error in calculating the numbers of herring larvae
per square metre surface, caught by one country, the results of the North Sea
herring larval surveys in 1975/76 have had to be reappraised. These data,
and those collected in 1976/77 are presented in this paper.
They suggest that larval production in 1975, in all areas except Buchan, was
considerably less than in preceding years. In 1976 larval production remained
at a generally low level, although there was some increase in estimated
abundance in the Shetland/Orkney area.
Spawning stock sizes in the northwestern North Sea and in the Whitby/Dogger
area, as estimated from a regression of larval abundance on spawning stock
size, are 79 000 tons in 1975 and 87 000 tons in 1976 for these areas combined.
These estimates are rather lower than those produced by the Herring Assessment
Working Group for the Area South of 62°N from fisheries data.
Some factors which have a bearing on the planning of future sQrveys and on the
utilisation of these data for the estimation of stock size are discussed.

The results of the 11th International Survey of Herring Larvae in the
North Sea and Adjacent Waters, which was carried out during 1977/78, are
presented.
They indicate a marked increase in larval production in both the northwestern
and central North Sea compared with the previous two years. Some increase
was also apparent in the Buchan area and in the southern North Sea/eastern
Channel, although overall in these latter areas production was still at a
relatively very low level.
The spawning stock size of herring in the northwestern and central North
Sea,as estimated from sub-area regressions of larval abundance on spawning
stock size is 136 733 tons. It is likely that in addition a further
25 000 tons of herring spawned in the southern North Sea/eastern Channel.
The catches of herring larvae taken by different countries were compared.
It was found that there was no evidence of a significant difference in
the catches of the critical< 10 mm size category.

environment. At the second meeting of the former ICES Sub-Group on
Contaminant Levels in Sea Water (April 1977), it was agreed that proposals
for a baseline study of trace metals in the open ocean were premature and
impractical in view of the •state of the art• on this subject. In anticipation,
however, of this future programme, the Group agreed that the
preparation of a status report on selected trace metal measurements in sea
water WO\lld be very useful. This paper presents the findings of this
review. 1 )

This report presents the results of the fourth year of the Coordinated
Monitoring Programme. The programme began in 1974 after the 1972 baseline
survey of contaminant levels in fish and shellfish of the North Sea
(results reported in Coop.Res.Rep., No.39 (1974)) showed that, although
most of the area studied was only lightly contaminated, certain areas,
particularly coastal zones and the Southern and German Bights, should be
monitored annually. Thus, it was agreed that the results of the studies
conducted on a national basis in the identified areas should be reported
to ICES for inclusion into an annual Coordinated Monitoring Report. The
results of the first year of the programme, 1974, were published in Coop.
Res.Rep., No.58 (1977) and those from 1975 and 1976 were printed in
Coop.Res.Rep., No.72 (1977).

reports of the North Sea Gadoid 0-Group Surveys (since initiation) should be
edited and published as a Cooperative Research Report" (C.Res . 1977/ 1:7). The
surveys were initiated in 1969 by the Marine Lab oratory, Aberdeen, with
experi mental trawling for 0- group gadoids , but it was not until 1975 that the
first inter nati onal survey could be said to have taken place with the participat

manner in a fully coordinated survey . However, in order to make all the data

The objectives of the Group were to produce, for each of the stocks of cod, haddock,
whiting, plaice and sole:-
(a) a historical review of the fishery, and
(b) an assessment of the present stage of these stocks with particular reference
to the effects of changes in mesh-size and fishing effort.
In view of the magnitude of the task and the relatively short time available the Group
decide to make mesh-assessments their primary objective and to devote such time as remained
to the historical review and to effort assessments.

In 1966 the North-East Atlantic Fisheries Commission asked the
Liaison Committee of ICES for guidance regarding the effects of measures
proposed to conserve the Downs stock. In particular it enquired into the
effect of regulation of the Blf6den industrial herring fishery and the consequent
effects on the Downs stock. From previous international tagging
experiments it had been calculated that in 1957 and 1958 the juvenile fishery
removed about 16-19 per cent of the stock per annum. Because of the limited
extent of these experiments and the changed nature of the juvenile fishery,
it was proposed that a new tagging experiment should be made, spreading the
liberations of tagged herring over a longer period and at a higher rate of
tagging.

Reference is made to Section B.2 of the Liaison Committee's Report for
19 14 (Coop.Res.Rep., No.44) which sets out the advice concerning the
regulation of these stocks as formulated by the Liaison Committee at its
meeting in April 1974•
It will be noted that the recommended TACs for 1975 for Arctic Cod
were estimated on the basis of a presumed fishing effort in 1974 eQual
to that in 1973 which would result in a total catch in 1974 of about
680 000 tons. It seems likely, however, that the 1974 catch with the
breakdown of the tri-partite agreement and increased participation of
"third" countries will be considerably higher than this amount and
probably around 800 000 tons. There is thus a need for a revision of
the earlier advice and an ad hoc meeting of the North-East Arctic
Fisheries Working Group was arranged during the ICES 62nd Statutory
Meeting in Copenhagen. The report of this meeting was considered by
the Liaison Committee at its meeting on 5 October,

Since 1965 annual attempts have been made to estimate the abundance of late
summer and early autumn fish fry in the Barents Sea and adjacent waters.
The project has involved scientists and vessels of a number of nationalities.
Following the very promising results from these surveys it was decided at
the Statutory Meeting of the International Council for the Exploration of the
Sea in the autumn of 1969 to initiate a similar project in the waters around
Iceland, in the Irminger Sea and off East Greenland to see how the Barents
Sea methods worked in these areas. Investigations of this kind require that
the survey area is covered in as short a time as possible and multinational
participation was obtained and arranged through the Council.

74
1/10/2021 11:53 AMSøren Killerup Larsen
The world fisheries are at present in a difficult transitional stage.
The principle of fishery resources as a common property in the international
sense has largely been abandoned and a regime is emerging
based on the concepts of the proposed new Law of the Sea. The major
part of the problems of the transition to the new regime has been the
subject of elaborate negotiations in the various sessions of the UN
Conference on the Law of the Sea. There appears, however, to be one
set of problems which has not been dealt with extensively in these
negotiations, and this relates to the fact that in many areas of the
world and perhaps particularly in the North-East Atlantic, the distribution
of major fish stocks covers more than one zone of extended
fisheries jurisdiction. These resources shared between several zones
of extended fisheries jurisdiction or between such zones and international
waters represent an entirely new problem in international
fisheries work: to allocate between various national parties the
"ownership-rights" and management responsibilities for various parts
of a fish stock or unit resource

At its meeting in November 1976 NEAFC asked ICES to submit, as soon as
possible, information on the biology of and fisheries on stocks shared
between zones of extended fisheries jurisdiction.
In view of the magnitude of the work involved, and the urgency with which
some of the data was required, the Liaison Committee of ICES decided to
submit initially a report on the major stocks in the North Sea. This was
done (Coop.Res.Rep., No.74, 1978) in 1977, with an undertaking that a
subsequent report dealing with the other stocks in the Convention area
would be prepared, and submitted, as quickly as possible.
This report, which fulfills that undertaking, was prepared by the Advisory
Committee on Fishery Management in collaboration with various ICES
Assessment Working Groups, which were asked at their 1978 meetings to
review the drafts they had previously prepared, in the light of any new
information available. Because fisheries research by ICES member countries
has, in general, been more intensive in the North Sea than in other areas
the data available for the stocks dealt with in this report are less
comprehensive in many cases, than for those in the preceding one. They are,
however, the best relevant data available, and are presented here in the
hope that they will be of some help to the Commission and the other bodies
concerned with management and allocation problems in the areas concerned.
In the Introduction to the preceding report on this subject the Liaison
Committee commented on the general principles and problems in the management
of shared stocks under the new regime of extended zones of fisheries
jurisdiction. ACFM would wish to endorse these comments and to recommend
that they be read in relation to this report by anyone who has not already
done so.

1980CRRInteraction between the Fishing Industry and the Offshore gas/oil Industries

1/10/2021 11:48 AMSøren Killerup Larsen
At the 65th Statutory Meeting of ICES in September 1977 a special joint
session of the Gear and Behaviour Committee with the Fisheries Improvement
Committee was held on the interaction between the fishing industry and
the offshore gas/oil industries.
Information was requested on national regulations and procedures
relating to the coexistence of fisheries and gas/oil operations as well
as contributions on the potential hazard to each industry from the
operation of the other. In the single (half-day) session available it
was clearly not possible to deal comprehensively or in depth with the
subject and since most of the papers came from fishery scientists it was
inevitable that the emphasis should be on effects on fish stocks and
gear, but the question of damage to underwater pipe-lines was also considered.
A total of 17 papers were presented and discussed (see Appendix).
Subsequently it was proposed that we should edit the material for
publication as a Cooperative Research Report.
In assessing the contributions, we considered that authors should be
given an opportunity to update their presentations and that any additional
relevant material from the 1978 Statutory Meeting should be considered.
This allowed us to include a paper from USA. After further consultations
with the authors we have reproduced some papers more or less as originally
presented, while others have been abstracted or summarised.
It must be emphasised that offshore oil activities are continuously
developing, and that fishing patterns are changing, so both industries
are in a highly dynamic state. The picture presented by these papers
must thus be regarded as a limited snapshot of things in the period 1977/78.

2. The Chairman reminded the audience that it has been generally agreed that
the Dialogue Meetings have been useful, and the October 1980 Meeting
requested ICES to continue for the time being to invite to such meetings.
It had also been felt desirable if at the third meeting the management
representatives provided, as a feed-back, specific comments on the
regulation objectives which were implicit or directly stated in the reports
of ACFM. This task had been facilitated by ACFM spelling out the objectives
it has accepted as the basis of its advice and the policy it advocates in
order to reach them, in a separate section of its report.

discussed at the present meeting and these were agreed by the participants

countries. There were also participants representing the fishing

Communities were also represented. A List of Participants is given
in Annex 1.
2. The Chairman welcomed the participants and briefly outlined, what
had been achieved by the three previous meetings. What had started
largely as an explanation by the biologists of their methods and
working procedures, had gradually become a dialogue, which for each
meeting had been more specific. The two groups of scientists and
managers no¥ had a better understanding of each others' "language"
and the constraints under which they worked. This was one major
achievement. The other was the effect of the meetings on the work
and the reports of ACFM. One example is the grouping by ACFM of the
fish stocks according to the possibility for carrying out assessments
and formulating advice in the form of options (see Coop.Res.Rep.,
No.113, p.1-2)

is given in Annex 2, and the meeting agreed,

123
1/10/2021 11:28 AMSøren Killerup Larsen
The present report deals with an attempt to establish the
possibility of using the concept of "flushing time" in a practical
situation of the North Sea. The excercise should be looked upon as
a basis for further studies. Especially in connection with research
of marine pollution this may be relevant.
In that connection data given here might also be used in practical
pollution problems. At the present stage, however, this might easily
lead to mis-use of data that are presented for another purpose. And
although in the following some of the considerations given are of a
pratical nature in,order to illustrate the significance of-the concepts,
the aims of the report are primarily to contribute to scientific work,
and results presented here will only become more and more firm as they
are supported by further scientific evidence.
Transport processes in the sea, involving both advection and turbulent
diffusion largely determine the distribution of the concentration of
dissolved substances. Studies of .marine pollution require a description
of these transport processes and an understanding of the mechanisms
involved. Also for various other studies the transport processes in the
sea are of importance.

list of participants is given in Annex 1.
The President opened the meeting at 09.30 hrs, welcomed the
participants, and presented a brief introductory statement
(Annex 2). He indicated that fishery management consists of
three levels of activity: 1) establishing harvest levels
and structure, 2) allocating the harvest, and 3) enforcing
regulations. ICES is concerned only with the first of these
levels, but scientists alone cannot set harvest levels. The
tasks of the Dialogue Meeting are to: 1) explore the extent
to which managers and scientists agree on the kind of
scientific advice to be provided; 2) consider how best to
improve the quality and timeliness of stock assessments and
predictions; and 3) examine ways to improve communications
between scientists and managers.
Written presentations and discussion focused on five main
topics which are listed in Annex 3. Eight papers were submitted
to the meeting, five prepared by ICES scientists and
three by representatives from the management and industry
sides.

During its meeting in 1982, the ICES/SCOR Working Group on the
Study of the Pollution of the Baltic Sea (SCOR WG 42) agreed that
"Pilot Sediment Studies" should be initiated in its study area. A
basic pro9ramme proposed by an §.Q hQ~. Sediment Group, convened by
Dr L. Niemisto, was accepted. This programme was set up in order
to investi9ate several closely related tasks, including
a) problems of contamination history, reflected by contaminant
profiles in se9mented sediment cores,
b) material fluxes across the water-sediment interface, and
c) geochemical processes in the early stages of diagenesis.

The Sixth Dialogue Meeting was held
1987. It was co-sponsored by ICES and
Fisheries Commission and was hosted
European Communities (CEC) at the Centre
in Brussels on 27 October
the North-East Atlantic
by the Commission of the
Borschette.
The meeting was organized in the form of a debate involving an
expert representing each of the three groups involved in the
fishery management process (scientists, administrators/managers,
and the fishing industry), with provision for open discussion involving
the audience. The members of the debate were Mr David de
G. Griffith, fisheries scientist from Dublin, Ireland, member and
former chairman of the ICES Advisory Committee on Fishery Management
(ACFM); Mr Broer B. van der Meer, Director of the Netherlands
Institute for Fishery Investigations, IJmuiden and former
Director of Fisheries, Netherlands Ministry of Agriculture and
Fisheries, The Hague; and Mr Finn Bergesen, Jr, Secretary General
of the Norwegian Fishermen's Association, Trondheim.
Three major topics selected for consideration at the meeting were
stability, management systems, and long-term objectives for resource
utilization. The meeting was, therefore, divided into
three parts with separate debate and discussion on each topic.
The meeting was chaired by the President of ICES, Mr Ole Johan
0stvedt, with the ICES General Secretary (Dr Basil B. Parrish)
and Statistician (Dr Emory D. Anderson) serving as rapporteurs.
Others at the speaker's table included Mr Bernhard Vaske, Chair-man
of ACFM; Mr Peter J. Ogden, Acting Secretary, North-East Atlantic
Fisheries commission, London; and Mr Michael J. Holden,
Head of Division XIV-B-1, Directorate-General for Fisheries, Commission
of the European Communities, Brussels.

Introductions or transfers of marine and freshwater organisms in support of
aquaculture or various fishing initiatives have been increasing in numbers quite
rapidly in recent years. This document, prepared as a more deta'iled follow-up to
the 11Codes of Practice11 related to these movements which were prepared by the
International Council for the Exploration of the Sea (ICES) and the European
Inland Fisheries Advisory Commission (EIFAC), addresses some of the concerns and
provides advice related to proposed introductions or transfers. Areas covered are
inspection and certification, quarantine, pathology, genetics and ecology.
Universal concerns in the above mentioned areas which are common to any
introduction or transfer are outlined, as are those related to importations or
other movements which are part of established commercial practice or those related
to scientific study at research facilities. Specific examples of protocols,
mainly related to controlling disease organism spread, are included as are items
related to the methods of handling requests for introductions either at the
national or international level.

In 1982, it was decided to change the time table for the ACFM meetings. Instead of having
one main meeting in July dealing with most of the stocks, with an additional minor one in
November taking care of a few stocks, the work has now been more equally divided between the
two meetings, one in mid-May and one in late October/early November.
The time table of the assessment working groups had to be changed accordingly, and the advice
on different stocks has been distributed between the two meetings, taking into account
various factors such as the deadlines set by the management authorities for receiving advice,
timing of surveys, and collection of other scientific data, etc.

At its 1983 meeting the Industrial Fisheries Working Group identified the
need for a workshop to be held to consider stock separation and other
biological problems relating to the assessment of the sprat stocks in the
North Sea and adjacent areas. The essential problems were addressed in
discussion papers presented at the 1984 and 1985 ICES Statutory Meetings
(Bailey 1984,1985), and in 1985 the Pelagic Fish Committee put forward a
recommendation that a "sprat biology workshop" should be held late in 1986.

The Seventh ICES Dialogue Meeting was held on 28 November 1989 in
the Strand Palace Hotel, London. It was co-sponsored by ICES, the
North-East Atlantic Fisheries Commission (NEAFC) and the International
Baltic Sea Fishery Commission (IBSFC). The main theme of
the meeting concerned the biological, economic and social considerations
in determining the objectives of fishery management,
taking into account the management of shared stocks.
The aim of all Dialogue Meetings has been to promote communication
among three groups of people concerned with fisheries management,
namely 1) fishery scientists, 2) national and international
administrators and 3) members of the fishing industry.
Each group was well represented making a balanced discussion
possible. Of the approximately 110 participants (from 14
countries), 28% were scientists, 37% were administrators and 35%
represented the industry. A list of participants is given in Appendix
1. The meeting was conducted in English but simultaneous
interpretation into English, French and Spanish was provided by
the Commission of the European Community.
The meeting was chaired by Mr Jakob Jakobsson, President of ICES.
Four speakers representing fisheries science, economics, administration
and the fishing industry presented papers and led the
discussion. The speakers were Dr John Shepherd (MAFF Fisheries
Laboratory, Lowestoft), Professor Rognvaldur Hannesson (Norwegian
school of Economics and Business Administration, Bergen), Mr
Michael Holden (Commission of the European Communities, Brussels)
and Mr John Goodlad (Shetland Fishermen's Association, Lerwick).
The ICES General Secretary and Statistician acted as rapporteurs.
The meeting comprised two sessions, one on Stability and the
other on Objectives, with each beginning with presentations from
the speakers and ending with open discussion.
Copies of all the papers prepared by the speakers had been circulated
to participants prior to the meeting. Copies of reports
of the ICES Advisory Committee on Fishery Management (ACFM) for
1989 were available at the meeting together with samples of 1989
ICES assessment working group reports. A list of technical terms
and their definitions, which was available at the meeting, is
given in Appendix 2.

Nominal catches in the North Sea area (Sub-area IV and Division IlIa), the Norwegian Sea and
off the Faroes (Divisions IIa and Vb), the Western area (Sub-areas VI and VII and Divisions
Vllla,b,d,e) and the Southern area (Division Vlllc and Sub-area IX) are given in Tables
6.1.1-6.1.4.
These tables do not give actual catches by area for 1969 due to misreporting. Estimates of
quarterly catch of mackerel by division or sub-area in 1969 are given in Table 6.1.5.
Two stock units - North Sea and Western - are considered. The stocks mix during the second
half of the year, particularly in the northern North Sea (Division IVa), but the proportion
of mackerel from the North Sea stock in the catches is very small due to the inferior size
of this stock in relation to the Western stock.
As for previous years, it has not been possible to split the 1969 catches by stock. All
mackerel caught in Sub-areas II, IV, VI, VII and Divisions IlIa, Vb, Vllla,b were allocated
to the Western stock. This includes an estimated quantity of about 3,000 t North Sea
mackerel which is considered insignificant in relation to a total catch of 567,000 t assessed
as Western stock mackerel.
Data on actual, quarterly distribution of the mackerel fisheries in 1969 are available. Compared
to 1966, the distribution was, as in 1967, more southerly during the July-October
period, illustrating previously observed year-to-year variations in distribution and migration.
Data relating to the fisheries for mackerel in the Southern area (Divisions Vlllc and IXa)
are now being collected and analyzed, but are yet insufficient for any analytical assessment.

In many cases, nutrient monitoring data form the most representative source
for environmental studies and modelling; however, in all the above
exercises, discrepancies have been found both in methods and in results.
This is especially true for field exercises and, while it is recognised that
the variability in environmental results Includes the variability associated
with sampling and subsequent sample handling, differences in purely analytical
methods are best detected by means of laboratory intercomparisons.
Field exercises are difficult to organise, and the effect of unknown factors
on the results can be considerable, as shown in the Joint International Multiship
Investigation of Patchiness in the Baltic Sea (PEX) exercise.

At the end of the twentieth century when Man has, for
decades, been a major environmental and climatic influence
on the earth on a global or at least regional scale,
one cannot assume that a sea surrounded by nine highly
industrialized countries with an intensive agriculture could
- as a whole - still be in a 'natural state'. In part, the
anthropogenic influences have 'only' accelerated (or
slowed down) natural processes, for example,
eutrophication, erosion/abrasion and weathering, by mainly
physical and chemical disturbances (loading of nutrients
and heavy metals, shipping, fishing, especially bottom
trawling, mining). However, in addition, xenobiotics
and radionuclides contribute to new threats for the ecosystem,
its compartments or even for Man as a consumer of
sea-<lerived food.

The assessments presented in this report are carried out using the best catch data available to the working groups
and to ACFM. These data are not necessarily identical with the official statistics but, where appropriate, include
estimates of unreported landings as well as corrections for misallocation of catches by area and species. Despite
considerable effort exerted to this problem, there is no guarantee that all instances of misreporting were discovered.
Often working group catch data are collated on a stock basis rather than an area basis, and so straightforward
comparisons between these figures and the official statistics, which are provided on an area basis, are not
appropriate.
In the assessments, the working groups try to estimate the total catch taken, including slipped catches, discards,
landings which are not officially reported, and the composition of the industrial by-catches. These amounts of
different species, which have to be included in the estimates of what has been taken from a given stock in order
for the assessments to be correct, thus appear in the tables and figures produced by the working groups. These
levels of discards, slipped fish, unreported landings, and industrial by-catches vary considerably between different
stocks and fisheries, being negligible in some cases and constituting important parts of the total removal from other
stocks.

constituting important parts of the total removals from other stocks. Further, the catches· used by the working
groups are broken down into sub-divisions, whereas the officially-reported figures are reported by the larger

the regulatory commissions, specifically the Oslo and Paris Commissions and the Helsinki Commission, as
well as other issues considered relevant by the ACME. These deliberations were based on the most recent
reports of the following ICES working and study groups:

1/9/2021 12:02 PMSøren Killerup Larsen
This synthesis of information on spawning and life
history of North Atlantic cod stocks originated from two
separate initiatives, which were subsequently merged.
The ICES Larval Ecology Working (which became the
Recruitment Processes Working Group) began to bring
together the existing data on early life stages of cod and
haddock in 1987, using a checklist which was circulated
to Working Group members and participants at the ICES
Early Life History Symposium in 1988. The ICES Study
Group on Cod Stock Fluctuations (which became the
ICES/GLOBEC Working Group on Cod and Climate
Change) produced syntheses of Atlantic cod stocks as
appendices III and IV of its report in 1990 (ICES CM
1990/G:SO). The resultant information and a large
amount of additional material, produced by over thirty
contributors, whose names are given in Table 1, has been
edited and some of the information has been extracted
into Tables as a summary. A single reference list has
been prepared, but the task of indexing this list by key
words is not complete.

Intensive interdisciplinary studies of the Benguela Current upwelling system off the south west coast of southern Africa
were done for many years by groups closely connected to research staff of the South African Sea Fisheries Research
Institute. The upwelling in this region is particularly intense and many complex processes can be identified and
modelled. These findings may therefore provide as a useful model for setting up a sampling strategy for study of the
upwelling processes which occur off the west coast of Ireland, or off Northern Europe

1995CRRUnderwater noise of research vessels: review and recommendations
209
1/22/2021 10:58 AMSøren Killerup Larsen
The formation of the Study Group on Research Vessel
Noise came about because of increasing concern over
the effects of underwater noise radiated from research
vessels. Evidence has been steadily accumulating of
adverse fish reaction to some vessels. For the purposes
of fisheries research it is important that the natural
distribution of fish should be disturbed as little as possible
during population surveys, regardless of whether
the sampling is by means of trawl, or acoustic methods.
In this connection the statement has been made
that, "scientists making underwater observations and
measurements need quiet vessels for the same reason
that astronomers have to site their telescopes on
mountain tops, that is, to prevent the source of energy
they need to measure from being obscured by other
unwanted sources of this energy" (noise). The needs of
the fisheries scientist go further, because they are
seeking an elusive prey, sensitive to noise, not inanimate
objects.

The whitefish fisheries in Division VIa are predominantly
conducted by otter-trawlers fishing for cod, haddock and
whiting, with by-catches of saithe, anglerfish, megrim and
lemon sole. These trawlers use mesh sizes of 80-100 mm
depending on area and may at times discard considerable
amounts of young haddock and whiting. The majority of
these vessels are locally-based Scottish trawlers using
'light-trawls', but trawlers from Northern Ireland, England,
France and Germany also participate in this fishery. The
importance of Scottish seiners essentially targeted at
haddock has been declining in recent years as many of
these vessels have been converted to trawlers. The larger
Scottish trawlers opportunistically operate in a haddock
fishery at Rockall when occasional good year classes
recruit to the Division VIb stock. Although young saithe
are caught by coastal trawlers, the fishery for saithe
essentially takes place offshore to the west and northwest of
Scotland. Traditionally, this fishery has largely been
operated by the larger deep-sea French trawlers. However,
the number of these vessels has declined in recent years due
to economic difficulties. In the late 1980s, some of these
vessels diverted their activity toward deep-sea species,
notably orange roughy, bnt this fishery has become less
profitable recently. To a large extent, the roundfish fishery
in Division VIa is an extension of the similar fishery in the
North Sea.

In 1981, the International Council for the Exploration of
the Sea established a Working Group on North Sea
Benthos (Council Resolution 1981/2:6). One of the aims
of the Working Group was to provide synoptic maps of
qualitative and quantitative aspects of the status of the
benthic communities in the North Sea. After reviewing
the state-of-the-art of benthos investigations, the Working
Group concluded that the available data were not
sufficient to produce such a complete review of the fauna!
assemblages. The Working Group therefore
recommended that a large-scale benthos survey, covering
the whole North Sea and using standard sampling and
processing techniques, be initiated to solve this problem
(ICES, 1982; ICES, 1983). The programme was planned
in more detail at the Working Group meetings in 1984
and 1985 (ICES, 1984; 1985).

The precautionary approach is increasingly being
recognised as a basis for assessment and management
of fish stocks. Implementation of the precautionary
approach requires both additional work by, and
dialogue between science and management. There are
analytical tasks which are inherently the responsibility
of science, and decisions which are inherently the
responsibility of fishery management agencies.
An early step in implementing the precautionary
approach is the identification and agreement of explicit,
operational management objectives. Such objectives
should recognise biological, social, and econontic
characteristics and constraints of fisheries and address
short, medium, and long time frames.
Current developments in application of the
precautionary approach in assessment and advice
suggest that, from the management side, objectives
should be agreed within the biological constraints in
terms of properties of stocks and degrees of risks which
are acceptable or likely to trigger management actions.
From the scientific Side, work is underway at ICES on
how to relate biomass and fishing-mortality based
reference points to properties of stocks and risk in
various time frames, within a precautionary framework.
As a part of the dialogue needed, ICES will provide a
summary of the progress made so far in developing a
framework for precautionary reference points in 1998

1/3/2021 12:08 PMSøren Killerup Larsen
The ICES NANSEN (North Atlantic - Norwegian Sea Exchanges) project was initiated by Council Resolution
1985/4:9 to study the exchanges of water, heat, and other properties across the Greenland-Scotland Ridge between the
Atlantic Ocean and the areas northeast of the ridge. Across this ridge, warm, saline water makes its way northeastward
in the upper layers while cold, fresher water returns south-westward partly in the upper layers along the
Greenland coast and partly as deep overflows at several locations across the ridge. These exchanges are of major
importance for the global thermohaline circulation as well as for the regional climate of the Nordic Seas and the
Arctic with their surrounding landmasses. ICES has long recognised the importance of these flows by mounting the
Overflow '60 and Overflow '73 experiments which focused mainly on the cold, deep overflows. The NANSEN Project
was initiated to study in more detail the Atlantic water flow north-eastward over the ridge as well as the return flows,
with most emphasis on the eastern part of the area.

fisheries discussed at this meeting were those of the Bay of Biscay and the Atlantic waters off the Iberian Peninsula. The
meeting was co-sponsored by ICES and the European Commission.
About 100 French, Portuguese, and Spanish representatives of fishermen attended. Spain was by far the best represented.
There were a significant number of researchers from fisheries research institutions in France, Portugal and Spain. High level
representatives of National Administrations in charge of fisheries and of DG XIV also participated. The timetable of the
meeting is given in Annex l and the list of participants in Annex 2.
The General Secretary for Maritime Fisheries in Spain, Mr. Jose Loira, welcomed the participants and pointed out how

Since the early 1980s there bas been a development of
semi-pelagic trawling for cod and whiting,
predominantly by vessels from Northern Ireland. Some
of these vessels switch between pelagic trawling and
twin-trawl fishing for Nephrops depending on fishing
opportunities and market demands.

Recording the flora and fauna of habitats has long been practised. In more recent times much attention has been and is being paid to both the deliberate introduction by man of species exotic to marine areas and to the inadvertent appearance of such alien species by factors involving man and other agents. In the marine environment of the ICES area it is inevitable that almost all observations are confined to coastal zones in the ‘open’ marine habitat of the North Atlantic. For ‘semi-enclosed’ areas such as the Mediterranean, Baltic and North Seas and ‘enclosed’ areas such as the Great Lakes a greater degree of observation over the whole is possible. Part of this recording of new introductions and transfers of exotic species which are part of an established trade are observations of the impact of the exotic either because it is successful in establishing reproducing populations or because of its presence.
The First (1980) Status Report on Introductions of Non-Indigenous Marine Species to North Atlantic Waters was prepared by the ICES Working Group on Introductions and Transfers on Marine Organisms (WGITMO) (Anon 1982). This second report, also prepared by WGITMO, covers the decade 1981–1991. It includes summaries of the national reports to the working group from member countries of ICES of introductions and transfers of fish and invertebrates. Because there has been a limited response on plant introductions both in the previous and current decade a comprehensive review of plant introductions with an additional section on the threat from the green algae Caulerpa taxifolia has been included.

The Working Group on Seabird Ecology was requested
by the Biological Oceanography Committee to assess the
issues most likely to be raised within the ICES
community concerning the foraging ecology of seabirds
and waders, and the potential interactions between these
groups of birds and fisheries. In responding to this
request, the Working Group has listed a number of issues
likely to be of importance. The Working Group
recognized that each of these issues by itself is
potentially the subject for new research and/or for a
major review. The Working Group restricted itself to the
identification of issues, and has used this list as the basis
for developing possible future reports by the Working
Group on Seabird Ecology, singularly, or in co-operation
with other ICES Working Groups or Committees.

The ICES Advisory Committee on the Marine Environment (ACME) met from 8-13 June 1998 at ICES Headquarters in
Copenhagen. As part of its work during this period, the ACME prepared responses to the requests made to ICES by the
OSPAR Commission and the Helsinki Commission. This report contains these responses. In addition to responses to direct

A key component of the ICES/GLOBEC Cod and
Climate Programme (ICES 1993) has been the
facilitation of retrospective analyses of physical
oceanographic and other climate-related factors
associated with observed changes in important fishery
resource species. Previous “backward-facing” workshops
have considered case studies of cod in the Northeast
Arctic and tilefish in the Northwest Atlantic (ICES 1995;
1996), and synthesized available information in new and
informative ways (e.g., Marsh et al., 1999).

The roundfish fisheries in the Irish Sea are conducted
primarily by vessels from the bordering countries (UK
and Ireland). The majority of vessels are otter-trawlers
fishing for cod, whiting and plaice, with by-catches of
haddock, anglerfh, hake and sole. The mesh size is
80mm and 8Omm square mesh panels have been
mandatory for UK otter-trawlers since 1993, and for
Iriih trawlers since 1994. The number of Irish vessels
operating in this region has declined in recent years.
Fishing effort in the England and Wales fleet of vessels
longer than 12.2 m declined rapidly after 1989. and over
199211995 was about 40% of the effort reported in the
1980s, although it has increased again in recent years.
Since the early 1980s there has been a development of
semi-pelagic trawling for cod and whiting,
predominantly by vessels from Northern Ireland. Some
of these vessels switch between pelagic trawling and
twin-trawl fishing for Nephrops depending on fishing
opportnnities and market demands

This is the seventh intercomparison exercise for trace metals in sea water organized by the Marine Chemistry Working Group (MCWG) of the International Council for the Exploration of the Sea (ICES). It is designated as 7/TM/SW.
The MCWG at its annual meeting in March 1995 formulated a proposal to conduct an intercomparison exercise for trace metals in coastal sea water in order to give laboratories from the participating countries an opportunity to assess their capabilities regarding this type of environmental analysis. The last study of this nature (6/TM/SW) carried out by the MCWG involved estuarine waters and took place in 1986 (Berman and Boyko, 1988).

2000CRRReport on Echo Trace Classification
238
1/2/2021 1:52 PMSøren Killerup Larsen
The standard use of fisheries acoustics is to estimate fish
or plankton abundance in the context of a stock assessment
survey. It is also used to map the abundance distribution
of these resources. However, it is generally agreed
that there is a great deal more information available from
the acoustic data collected during such surveys than a
simple integration of target species biomass. This report
describes the state-of-the-art in the extraction of such information.
This can be defined as Echo Trace Classification
(ETC).
The study of Echo Trace Classification (ETC) is the
characterisation of objects or features seen in an
echogram and relating these together to understand more
about the behaviour and biology of the organisms
involved.

The Advisory Committee on the Marine Environment
(ACME) is the Council's official body for the provision
of scientific advice and information on the marine
environment, including marine contamination, as may be
requested by ICES Member Countries, other bodies
within ICES, relevant regulatory Commissions, and other
organizations. In addition, at the 1998 Annual Science
Conference, the Council decided that ACME would
handle all advisory tasks other than the standard fishery
advisory requests, which are handled by the Advisory
Committee on Fishery Management (ACFM). However,
the ACFM will review fisheries-related ecosystem
advice before it is sent to clients.
In handling the requests, the ACME draws on the
expertise of its own members and on the work of various
expert ICES Working Groups and Study Groups. The
ACME considers the reports of these groups and requests
them to cany out specific activities or to provide
information on specific topics.
The ACME report is structured in terms of the topics
covered at the ACME meeting on which it has prepared
scientific information and advice; the topics include both
those for which information has been requested by the
Commissions or other bodies and those identified by the
ACME to enhance the understanding of the marine
environment. Information relevant to the Commissions'
requests and specific issues highlighted by the ACME
for their attention are summarized in Section 2 for the
OSPAR Commission and Section 3 for the Helsinki
Commission, where the individual work items from each
Commission are listed and related to relevant sections of
the main text. The full advice in response to the
European Commission DG XIV request concerning
potential impacts of sandeel fisheries on predator
populations is contained in Section 4 of this report.

2001CRRReport of the Workshop on Gadoid Stocks in the North Sea during the 1960s and 1970s. The Fourth ICES/GLOBEC Backward-Facing Workshop
244
1/2/2021 1:48 PMSøren Killerup Larsen
The Fourth ICES/GLOBEC Backward-Facing Workshop was held in Aberdeen, UK during 11–13 March 1999. The
Workshop was commissioned by the ICES Working Group on Cod and Climate Change, with terms of reference set out
in ICES Council Resolution 2.22 (C.Res.1998/2.22) (Appendix 1).
The objective of the Workshop was to examine the causes of the increases in abundance of gadoid fishes in the North
Sea which occurred during the 1960s and early 1970s, an event which has been referred to as the ‘gadoid outburst’. The
Workshop followed the pattern established by previous Backward-Facing Workshops by using a combination of
retrospective analysis, new process studies and modelling in order to interpret the causes of past population events.
Previous workshops have investigated the tilefish kill during 1881/82 in the Northwest Atlantic (Backward-Facing I;
ICES CM 1995/A:7), the changes brought about by a cold period in the Barents Sea and Baltic (Backward-Facing II;
ICES CM 1996/A:9), and the gadoid outburst in the Northwest Atlantic (Backward-Facing III; ICES CM 1998/C:9 and
ICES Cooperative Research Report 234).
The Workshop reported to the Working Group on Cod and Climate Change (WGCCC), to the Oceanography,
Resources Management, and Living Resources Committees at the 1999 Annual Science Conference, and to the
Advisory Committee on Fisheries Management (ACFM) at its May 1999 meeting

2002CRRThe Annual ICES Ocean Climate Status Summary 2000/2001
245
1/2/2021 1:47 PMSøren Killerup Larsen
The North Atlantic Oscillation (NAO) Index continued to recover to positive values up to and including winter 2000 (winter is defined by the year of the January), though with some indication of an eastward shift in the NAO dipole pattern. The result was that most parts of the area under review showed moderate or warm conditions in 2000. Though the climatic data set for winter 2001 is not yet complete, early indications are that the NAO index has undergone a sharp return to negative conditions.
Surface temperatures off West Greenland were relatively warm during the summer of 2000 due to mild atmospheric conditions. Stronger inflows of polar water were noted.
Ocean conditions in the Northwest Atlantic cooled slightly during 2000 relative to 1999 values, but were near or above normal in most areas. Sea-ice extent also increased slightly over the light ice conditions of 1999. An increased southward transport of polar waters was noted on the Labrador shelf.
The surface waters of the Labrador Sea were observed to be slightly cooler, fresher and denser in the summer of 2000 compared to 1999. More convection and overturning took place in the Labrador Sea during the 2000 winter than in recent years, but not as intense as during the early 1990s.
In Icelandic waters, 2000 revealed in general relatively high temperatures and salinities as in the last 2-3 years, following the very cold years of 1995 and 1996, although temperatures were also cooler than 1999 in this area.
The annual mean air temperature over the southern Bay of Biscay during 2000 remained at nearly the same value as during the two preceding years. Surface waters were slightly cooler and fresher than in previous years.
Early 2000 saw a peak in the temperature of surface waters in the Rockall Trough, caused by an influx of unusually warm water into the region. By the spring of 2000 the temperature had dropped somewhat, though it remained above the long-term mean.
2000 was the sixth warmest year since 1971 in the North Sea, in terms of annual mean sea surface temperature. All months were warmer than average, except for June and July. There was evidence of a large input of freshwater from the Baltic.
Since 1996, temperatures have increased in the southern and central Norwegian Sea. In 2000 the warming continued at the southern section while a cooling occurred at the central section. In the northern Norwegian Sea the temperature since 1996 has been close to the long-term average.

2001CRREffects of Extraction of Marine Sediments on the Marine Ecosystem
247
1/2/2021 1:46 PMSøren Killerup Larsen
The marine aggregate extraction industry is well established and continues to grow in a number of ICES Member Countries, contributing up to 15 % of some nation’s demand for sand and gravel. Demand for construction has remained relatively stable, with most major increases in extraction being associated with land reclamation for major projects, or for beach replenishment. Some major projects being considered would substantially increase annual demand in the years of their construction.
Since 1992 further reserves of sand and gravel have been reported in both the Baltic Sea and the North Sea. Reserves are not evenly distributed and the reserves of coarse marine aggregates must be considered finite, as should sand reserves in the Baltic. Fine sands are abundant in the North Sea and adjacent areas.
There are no realistic alternatives to the use of marine aggregate material for most beach replenishment and major coastal reclamation schemes. Strategic planning is essential for the future supply of materials, particularly for major construction projects. Most countries have reported concerns about the extraction of aggregates from both the land and sea, and the sustainable use of finite reserves is seen as a key issue for the future. Many countries are encouraging better use of alternative waste materials where they are appropriate in construction and landfill contexts.

1/2/2021 1:43 PMSøren Killerup Larsen
A Sea-going Workshop for intercomparison and evaluation of methods for sampling and determination of zooplankton in terms of biomass and species composition was held in a fjord environment (Storfjorden at Møre, western Norway) from 2 to 13 June 1993. The workshop was carried out with the German Research Vessel “A.v. Humboldt” (Chief Scientist Lutz Postel) and the Norwegian Research Vessel “Johan Hjort” (Chief Scientist Hein Rune Skjoldal) and involved a total number of 38 scientific personnel from eight countries. The Workshop had two objectives. The first was to assemble a number of instruments to collect zooplankton data and to conduct a series of field experiments that would enable an intercomparison of their results (Table 1). The intercomparisons included gear such as MOCNESS, BIONESS, MULTINET, LHPR, OPC, CPR, WP-2 net (Figure 1), and acoustical recordings at four frequencies (18, 38, 120, 200 kHz). The sampling experiments and some results were presented in a preliminary report (Skjoldal et al., 1993). Some of the data have appeared in more recent publications (Hays, 1994; Wieland et al., 1997; Halliday et al., 2001).
The second objective was to conduct a seminar workshop onboard Research Vessel “Johan Hjort” during the period of the two ship field work, which was attended by 20 scientists. The purpose of the seminar was to discuss issues related to net sampling and use of optical and acoustical techniques for determination of biomass and distribution of zooplankton.
Both of these activities were intended to provide background for material for the ICES Study Group of Zooplankton Production (now the ICES Working Group on Zooplankton Ecology), which was in the process of beginning the task of preparing the “ICES Zooplankton Methodology Manual” (Harris et al., 2000).

The NAO: The North Atlantic Oscillation (NAO) index has been slowly recovering to positive values since the extreme negative value of 1996. However, during the winter preceding 2001 it again became negative. The response seen throughout the ICES area to the 1996 switch of the NAO has not been observed in 2001, probably due to a different pattern of sea level pressure over the North Atlantic. In 2001 the pattern exhibited a large weak positive anomaly stretching from northern Scandinavia to Newfoundland.

252
1/2/2021 1:42 PMSøren Killerup Larsen
Growth rate varies widely among cod stocks. Large changes in growth rate have also been observed within many cod stocks and have important consequences for the productivity of these stocks. Variation in growth rate may reflect effects of temperature change, density dependence (i.e., changes in per capita prey availability due to variation in prey or cod abundance), changes in maturation schedules, changes in size-selective fishing mortality, changes in activity of the fish or adaptive (genetic) change. An understanding of the causes of variation in growth rate among and within cod stocks may lead to improved forecasts of stock biomass and productivity, and is required to assess the likely impacts of climate change on cod populations. The ICES/GLOBEC Working Group on Cod and Climate Change held a Workshop on the Dynamics of Growth in Cod in May 2000, with the aim of exploring the causes of growth variability and developing a single growth model for cod that will allow interpretation of information from all parts the geographic range of cod.
As a follow-up to the Workshop, a Theme Session was held at the ICES Annual Science Conference in Oslo in September 2001 on Growth and Condition in Gadoid Stocks and Implications for Sustainable Management. Thirty papers were presented and are included in this Cooperative Research Report as a CD-Rom containing abstracts, extended abstracts or full papers.

The six articles in this number of the ICES Cooperative Research Report series provide an overview of important developments in key fields of marine science in the ICES Area between 1979 and 1999. They constitute a review of the twenty years of progress since the date of the last article contained in Study of the Sea, an anthology of material stem-ming principally from ICES publications and edited by Edgar M. Thomasson, former ICES Librarian/Information Officer (Fishing News Books, 1981).
The Bureau Working Group on the Planning of the ICES Centenary, through its Chair, Michael M. Sinclair, and John Ramster, asked Pierre Petitgas to coordinate the preparation of this publication. It was mutually agreed that a balanced and unbiased review of recent work conducted under the auspices of ICES would best be undertaken by the younger generation of marine scientists.

The ICES Advisory Committee for Fishery Management met twice in 2001, 21 - 30 May- and 9 - 17 October 2002. Both meetings were held at the ICES Headquarters, Palægade 2–4, Copenhagen. Attendance is listed on the following pages.
ACFM in its advice includes a description on how the Precautionary Approach have been interpreted in the ICES advice, see Form of Advice in the Introductory Chapter.
The reports are in response to requests from Management Commissions (EC, IBSFC, NEAFC, and NASCO) and from member countries. The management advice is presented stock by stock in Sections 3 to 8 where also the answers to special requests are given.
The requests from Management Commissions are now divided into two parts: recurrent advice that is specified by Memorandum of Understanding between the Management Commissions and ICES and Special Requests. Recurrent advice includes assessment of stock status and management advice for the more important stocks in the Northeast Atlantic. This advice is provided in the same form as used by ICES Advisory Committee for Fishery Management in recent years.

In November 2000, ICES indicated that a number of cod stocks and the stock of northern hake were at serious risk of collapse. Following this, various emergency measures covering these stocks were enacted in 2001 by Norway and the EU. This was in addition to measures adopted by the EU to aid recovery of Irish Sea cod in the previous year. Proposals for longer-term recovery plans for these stocks were also made by the EU. These proposals include multi-annual recovery plans for northern hake and for cod in the North Sea, to the west of Scotland, in the Kattegat, and in the Irish Sea.
The proposed recovery plans aim to increase spawning stock biomass, SSB, to above the adopted biological reference point, Bpa, of each stock. The necessary tools proposed to achieve recovery are TACs set to ensure a high probability that SSB will increase annually by 30% for the cod stocks and 15% for the hake stocks. Within the recovery period there is a proposed maximum annual variation of TACs of no more than 50% from year to year. The tolerance for year-to-year changes in TACs is symmetric, and has higher priority than ensuring the target increase in SSB if the two rules are in conflict. The rule with highest priority is that fishing mortality should not be permitted to exceed Fpa in any year. To achieve the necessary decreases in fishing mortality, fishing effort limitations are also an integral part of the proposal in addition to measures to temporarily close fishing areas and to increase monitoring and control of fishing vessels.

In some parts of the northeast Atlantic where the continental shelf is narrow, such as off Portugal (including Madeira and the Azores), there are traditional fisheries, for example for black scabbardfish (Aphanopus carbo) and red (=blackspot) seabream (Pagellus bogaraveo), which have been exploiting deepwater species for many years. Other traditional species are ling, blue ling, and tusk, which have supported large fisheries in wide areas for several decades. The existence of other potentially exploitable stocks in the ICES area has been known since the 1960s and 1970s. However, before the 1980s, with the exception of a fishery for species such as roundnose grenadier (Coryphaenoides rupestris) there was little interest from the fishing industry in exploiting stocks in international waters.
Since the 1980s, dwindling resources on the continental shelves of the North Atlantic have encouraged the development of fisheries in deeper waters. There has been a tendency for fisheries for species such as anglerfish and Greenland halibut to extend into deeper waters, and new fisheries have developed to target the new deepwater species that have been found there. Deepwater species such as the argentine or greater silver smelt (Argentina silus) and roundnose grenadier (Coryphaenoides rupestris), which were previously by-catch species have been targeted within the ICES area for the last two decades. Orange roughy (Hoplostethus atlanticus) has been a target species since the early 1990s

The ICES Advisory Committee on the Marine Environment (ACME) met from 3 to 7 June 2002. As part of its work during this period, the ACME prepared responses to the requests made to ICES by the OSPAR Commission and the Helsinki Commission. This report contains these responses. In addition to responses to direct requests, this report summarizes the deliberations of ACME on topics for which advice was not directly requested but for which the ACME felt that there was information that would be of interest to the Commissions, ICES Member Countries, and other readers of this report.
As a result of the creation of the Advisory Committee on Ecosystems (ACE), several topics previously handled by ACME have been moved to the remit of ACE and scientific information and advice on these topics can be found in the ACE report for 2002. The topics covered include ecosystem effects of fishing, ecological quality objectives, ecosystem modelling and assessment, marine mammals issues, biodiversity issues, and marine habitat classification and mapping.

1/2/2021 1:34 PMSøren Killerup Larsen
When ICES agreed to publish this collection of papers from the 1996 Baltic Marine Science Conference it had just
completed devising a new structure for its Science Committees. This structure included an ecosystem-based group, the
Baltic Committee, which reflected the strong interest of ICES in supporting the community of Baltic scientists, as well
as its recognition that the Baltic would provide a valuable test bed for its ambition of developing ways to manage
ecosystems in an integrated way. This ambition is still cherished and is manifested now, not only in a thriving Baltic
Committee, but also through its active support, in its Secretariat, of the Project Office of the World Bank’s GEF “Baltic
Sea Regional Project (BSRP)” under the leadership of Jan Thulin. BSRP is an ambitious new project for managing the
Baltic Sea ecosystem.
ICES recognised the importance of the Conference by sending the Chair of its Advisory Committee on the Marine
Environment (Dr Katherine Richardson) to represent its interests there. Katherine contributed to the Conference by
making a presentation on “The Baltic Sea – A Grand Challenge for ICES”. In this she explained ICES interests from a
Baltic perspective and how ICES supports Baltic science. In particular she noted that almost half of the Member
Countries of ICES are in fact Baltic countries, which meant that ICES interests in the region had a very firm foundation.
She also noted that Baltic science must be steered to address all the vital problems of the area in a multidisciplinary
way, and that ICES is the organisation best suited to undertake the required steering.
This collection of papers represents an excellent cross-section of most of the current science issues pertaining to the
Baltic. It is a document that will be put to good use within ICES and that will also be of great value to the whole Baltic
community and anyone else interested in the scientific understanding of the Baltic Sea.

1/2/2021 1:34 PMSøren Killerup Larsen
This is the third ICES Cooperative Research Report produced by the Working Group on Seabird Ecology, following on from Reports on seabird/fish interactions (ICES Cooperative Research Report No. 216) and the diets of seabirds and the consequences of changes in food supply (ICES Cooperative Research Report No. 232). This ICES Cooperative Research Report focuses on the use that might be made of seabirds as monitors of the marine environment.
Section 2 examines the possibilities of using seabirds to monitor marine pollution, and recommends that they be used in monitoring a variety of substances. These recommendations are further developed in Section 5. Subsequent to this work, several of these recommendations have been developed for possible use as Ecological Quality Objectives (EcoQOs) under OSPAR and the North Sea Conference process. Ministers from around the North Sea adopted an objective in relation to the proportion of oiled common guillemots found dead or dying on beaches that “the proportion of such birds should be 10% or less of the total found dead or dying, in all areas of the North Sea (Bergen Declaration). In addition, Ministers requested that work continue towards defining EcoQOs in relation to mercury concentrations in seabird eggs and feathers, organochlorine concentrations in seabird eggs and plastic particles in the stomachs of seabirds. These decisions demonstrate the usefulness of seabirds in this area

In most areas of the North Atlantic during 2002 temperature and salinity were higher than the long-term average.
The North Atlantic Oscillation (NAO) index switched back to negative conditions during the winter preceding 2001, having recovered in the previous four years from the extreme negative value of 1996, which had brought to an end a period of extreme and persistent positive NAO index in the late 1980s/early 1990s. The 2002 NAO index showed a return to positive values which for the winter as a whole were not extreme, although individual months exhibited extreme and opposing sea-level pressure anomaly patterns

The ICES Advisory Committee for Fishery Management met twice in 2003, 27 May–5 June and 8–16 October 2002.
Both meetings were held at ICES Headquarters, Palægade 2–4, Copenhagen. Attendance is listed on the following pages.
The report includes a description on how the Precautionary Approach has been interpreted in the ICES advice (see
Form of Advice in the Introductory Chapter). The Form of Advice has been changed since last year with respect to the
mixed fisheries on demersal stocks in Division IIIa and Subareas IV, VI, VII, VIII, and IX and is now built on an explicit consideration of fisheries impact on the fish stock complex (mixed fisheries). This consideration has previously been presented in connection with the target stock. The evaluation of the individual stock status is unchanged, however; the management advice for mixed fisheries is presented under the Area Overviews (sections 3.5.1, 3.7.1, 3.8.1, 3.9.1,
and 3.10.1) and not in the sections dealing with individual stocks.
The reports are in response to requests from Management Commissions (EC, IBSFC, JNRFC, NEAFC, and NASCO)
and from member countries. The requests from Management Commissions fall into two categories: recurrent advice
that is specified by Memoranda of Understanding between the Management Commissions and ICES, and Special
Requests. Recurrent advice includes assessment of stock status and management advice for the more important stocks in the Northeast Atlantic. This advice is provided in the form used by ICES Advisory Committee for Fishery Management in recent years

programmes to estimate the abundance of seals and other marine mammals in the Baltic Sea; ACE also provided brief
additional material in relation to a request on marine habitat classification. In response to requests from the OSPAR
Commission, ACE has prepared an extensive review, and advice for further development, of four of the Ecological
Quality Objectives in the Pilot Project for the North Sea, as well as initial consideration of nine other Ecological Quality
Elements that are not part of this Pilot Project. ACE also completed its review, begun in 2002, of the evidence for the

In handling the requests, the ACME draws on the expertise of its own members and on the work of various expert ICES Working Groups and Study Groups. The ACME considers the reports of these groups and requests them to carry out specific activities or to provide information on specific topics.
The ACME report is structured in terms of the topics covered at the ACME meeting on which it has prepared scientific information and advice.
The topics include both those for which information or advice has been requested by the Commissions or other bodies and those identified by the ACME to enhance the understanding of the marine environment.

The large Asian gastropod mollusc Rapana venosa Valenciennes 1846 (Neogastropoda, Muricidae) is native to the Sea of Japan, Yellow Sea, Bohai Sea, and the East China Sea to Taiwan. This species has been introduced to the Black Sea with subsequent range expansion to the Adriatic Sea and Aegean Sea, the Chesapeake Bay on the East Coast of the United States, and the Rio de la Plata between Uruguay and Argentina. Reproductive populations are or appear to be present in all three receptor regions.
In addition, there are a limited number of reports of the species from the Brittany coastline of France, Washington State (USA), and two collections from the North Sea and New Zealand. The life history of this species makes it a viable candidate for continuing range expansion and new invasions facilitated by ballast water vectors. This review describes the current status of knowledge of the species in its home range and introduced populations.

2004CRRTrends in important diseases affecting the culture of fish and molluscs in the ICES area 1998-2002

1/2/2021 1:26 PMSøren Killerup Larsen
One of the regular Terms of Reference of the ICES
Working Group on Pathology and Diseases of Marine
Organisms (WGPDMO) since its inception in 1976 is to
provide and review annual national reports submitted by
ICES Member Countries on the disease status of farmed
fish and shellfish and to highlight new disease trends.
At its 2000 meeting, the WGPDMO emphasized that
these reports could be made even more informative if
presented as trends over a five-year period. This would
make it possible to obtain an impression of diseases that
might create problems in the near future. Such
information on emerging disease problems, especially in
new fish and mollusc species brought into aquaculture, is
considered to be of importance for countries planning the
development of production of these species.
In order to facilitate a wide dissemination, the
WGPDMO agreed that such a report should be brought
to the attention of ICES Member Countries, national and
international organizations involved in diseases of
farmed marine organisms, and interested scientists and
managers by means of appropriate publications. The
basic idea is to present this information in the ICES
Cooperative Research Report series and on the ICES
website as an internet publication which may be updated
biannually.
It is the intention for the future that this report will
address long-term trends in disease development in
mariculture.

2004CRRMesh Size Measurement Revisited
266
1/2/2021 1:25 PMSøren Killerup Larsen
In 1291 Philip IV the Fair, King of France, forbade “de
pescher avec engins de file de quoy la maille (n ait) la
moule d’un gros tournois d’argent” or, to fish with nets
with meshes smaller than the size of a silver coin of that
time (Hovart, 1985). This silver coin can be seen as a
predecessor of the present-day wedge gauge used to
check whether the meshes of fishing nets comply with
modern technical regulations.
A mesh gauge developed by C. J. W. Westhoff under
the auspices of the ICES Comparative Fishing Committee
became the standard gauge for research activities in
ICES countries in 1962 (ICES, 1962a) and became
known as the ICES gauge (Figure 1). To make a measurement
the ICES gauge exerts a fixed longitudinal
measuring force on the mesh. The recommended measuring
force is 4 kilogramforce (kgf). When the ICES gauge
is correctly used, the measurements are free of human influence.
Since its introduction the ICES gauge has been
generally used in selectivity experiments, to provide scientific
advice on minimum regulated mesh sizes. However,
since 1962 a wide range of new twines and netting
types have been adopted in the fishing industry. These
modern twines vary significantly in thickness and stiffness,
characteristics which affect both mesh size and selectivity.

The Thirteenth ICES Dialogue Meeting “Advancing scientific advice for an ecosystem approach to management:
Collaboration amongst managers, scientists, and other stakeholders” was held at Dublin Castle, Dublin, Ireland, on 26
and 27 April 2004. The meeting was one of the significant government-sponsored events held under the Irish
Presidency of the European Union and was opened by Ireland’s Minister for Communications, Marine and Natural
Resources, Mr Dermot Ahern, TD. The Marine Institute hosted the meeting. Participation is listed in Annex 1. The
programme is presented in Annex 2.
Since 1980, ICES has been organizing Dialogue Meetings to provide a forum at which scientists and managers can
come together to discuss matters of mutual importance in relation to the provision of scientific advice. The overall
objective of Dialogue Meetings is for ICES to communicate with its partners to ensure that there is good understanding
of mutual requirements in relation to the formulation and provision of advice. While early Dialogue Meetings were held
with groups of fishermen, this later evolved to dialogues more with the management organizations, principally the
Commissions. The Thirteenth Dialogue Meeting, with its broad and complex topic, brought together higher-level
government administrators at the national and international level, scientists involved in the process of developing
scientific advice in relation to an ecosystem approach, and a range of stakeholders from industries such as fishing,
chemicals, and shipping.

2004CRRThe DEPM Estimation of Spawning-Stock Biomass for Sardine and Anchovy
268
1/2/2021 1:22 PMSøren Killerup Larsen
The first part of the Section (Sections 2.2–2.3) summa-rizes the DEPM surveys that have been performed for sardine and anchovy in European waters. Emphasis is given to applications in Atlantic waters (where DEPM estimates are used routinely in stock assessment), but a brief description of known applications in the Mediterra-nean are also provided. The second part of the chapter (Sections 2.4 and 2.5) describes the most recent surveys in Atlantic waters (2002) in more detail, in order to demonstrate the survey and estimation methodology applied. Estimates are based on the traditional methods (Lasker, 1985; Hunter and Lo, 1997), which continues to provide the standard estimates of spawning-stock biomass for the purposes of stock assessment. However, results for 2002 should be compared to those obtained by the application of GAMs (Sections 3.3 and 3.4 for sardine and anchovy respectively), although GAM estimates of adult parameters and SSB are necessarily provisional (given that they were applied for the first time during the course of the most recent SGSBSA meeting). In the case of sardine, estimates based on mean survey values are compared to post-stratified and GAM-based estimates to clarify whether inappropriate sampling design under spatial structure in abundance and adult parameters can lead to biased biomass estimates (Stratoudakis and Fryer, 2000; ICES, 2002).

1/2/2021 1:22 PMSøren Killerup Larsen
Ocean climate data from 14 areas around the North
Atlantic are summarised in this report. Observations in
2003 are compared to the average conditions and the
longer-term trends in each dataset. Throughout the report,
all temperatures are quoted in °C. The key parameters
described in the report are seawater temperature and
salinity, but other oceanographic and meteorological parameters
such as heat flux, air temperature and sea level
pressure have been included for some areas. Figure 2 illustrates
the general pattern of oceanic circulation in the
North Atlantic in relation to the areas described in this
report.
In order to describe the ocean climate of area, key
datasets or time-series have been identified and presented.
The time-series have been carefully chosen to
represent conditions in a particular area. Sometimes the
time-series presented are measurements from a single location,
but frequently they have been constructed from
much larger and more complex datasets.
Where appropriate, data in this report are presented
as anomalies in order to show how the values compare to
the average or ‘normal’ conditions. For this report the
normal conditions refer to the long-term average of each
parameter during the period 1971–2000. For datasets that
do not extend as far back as 1971, the average conditions
have been calculated from the start of the dataset up to
2000.
Where necessary, the seasonal cycle has been removed
from each dataset, either by calculating the average
seasonal cycle over the period 1971–2000, or drawing
on other sources such as regional climatological datasets.
In the summary tables and figures, normalised
anomalies have been presented to allow intercomparison
of trends in the data from different regions (Figure 1 and
Table 1). The anomalies have been normalised by dividing
the values by the standard deviation of the data during
the period 1971–2000.

2004CRRThe Nephrops fisheries of the Northeast Atlantic and Mediterranean - A review and assessment of fishing gear design
270
1/2/2021 1:20 PMSøren Killerup Larsen
A review of the commercial trawl fisheries where Nephrops is a component of the catch was undertaken. These have considerable geographical coverage, ranging from Iceland to Portugal and into the Mediterranean. Nephrops is a highly important commercial species, valued at 208 million Euros (€) in 2001. The fisheries, with a few exceptions, are typi-cally multi-species, with the relative economic importance of Nephrops varying considerably between fisheries. Due to the smaller mesh size used in comparison to demersal fish fisheries, the degree of discarding of other species can be high. Additionally, due to the poor trawl selection characteristics, high grading, and legislative restrictions, the discard-ing of Nephrops is considerable in certain fisheries. A range of gear related technical measures are applied in order to mitigate discard levels, but further improvements are required. There is a lack of parameterised selectivity data for many of the existing technical measures, making any population independent assessment of their effectiveness impossi-ble. The report is divided into geographical areas and, for each of these, the fisheries are described, fleet adaptations to legislation are discussed and a review of the remedial measures that have been tested or applied is provided. Based on this information, fishery or area specific recommendations are made. In addition to the fishery specific recommenda-tions, more general recommendations are also given.

2005CRRVector Pathways and the Spread of Exotic Species in the Sea
271
1/2/2021 1:20 PMSøren Killerup Larsen
This document is intended to review the current state of knowledge concerning vectors of species introduc-tions, provide a brief overview of the potential risks associated with each broad category of vectors, and identify significant knowledge gaps. It has evolved from discussions of the ICES WGITMO and SGBOSV. Reports can be found at:
http://www.ices.dk/iceswork/wgdetailacme.asp?wg=WGITMO
http://www.ices.dk/iceswork/wgdetailacme.asp?wg=SGBOSV).
Although our understanding of the vectors is reasona-bly good, assigning vector strengths can be difficult and largely dependent on local or regional trading ac-tivities, and political and socio-economic circum-stances. Not all vectors continue to operate, and some become more powerful at specific times (e.g., Camp-bell and Hewitt, 1999). In this account, we attempt to outline the principal vectors that are likely to result in further non-indigenous species spread, including both introductions and transfers. Some vectors may trans-port fundamentally different sets of organisms (e.g. mussels attached to a ship’s hull, juvenile creatures within the mussel clumps, species encrusting on the mussels, species burrowing into the mussel shells, and pathogens or microalgae inside the mussels). Con-versely, some species may be spread by several differ-ent vectors (e.g., larval mussels may be transported in the plankton in ballast water; adult mussels may be transported as hull foulers, as intentional aquaculture species, or as associated species accidentally intro-duced with stock for culture).

2005CRREcosystem Effects of Fishing: Impacts, Metrics, and Management Strategies
272
1/2/2021 1:18 PMSøren Killerup Larsen
In this Chapter we present the logical development of the operational framework for selecting and using Ecosystem Objectives in fisheries management. We start with the framework of single-species reference points that ICES adopted for advice on fisheries management in 1997, and consider what extensions to the approach would be necessary to protect ecosystem properties, as well as single stocks, from serious or irreversible harm from fishing. Once the necessary extensions to the single-species reference points were identified, we considered what ecosystem management objectives would be appropriate in order to structure the selection and use of reference points for ecosystem properties. In undertaking this, it became clear that there was great potential for confusion of terms and concepts, particularly because many groups, with different professional make-ups, were publishing material on this subject. Therefore we undertook a careful exposition of the appropriate language for discussing ecosystem objectives, reference points, and related topics, to ensure that dialogue was consistent with the already established practices in both single-species fisheries management, and protection of habitats and species from pollutants.

This report is an input to the development of the European Marine Strategy (EMS). It was written by a core group established jointly by ICES and the European Commission and has been subject to wide stakeholder consultation in one of the working groups set up to support the development of the EMS process – the Working Group on Ecosystem Approach to human activities (EAM).
The report is directed at the Governments of countries participating in the Marine Strategy, including Member States as well as non-EU countries bordering the regional seas shared with the Community. The audience is also the European Commission and the Marine Conventions responsible for conservation and protection of the marine environment, and the scientific community. The core group worked during 2003–2004 with the following members:

2005CRRSpawning and life history information for North Atlantic cod stocks
274
1/2/2021 1:18 PMSøren Killerup Larsen
This synthesis of information on spawning and life history
of North Atlantic cod stocks is an update of ICES
Cooperative Research Report, 205 (CRR 205), published
in 1994, but it has been completely re-written. A comparison
between the current publication and its predecessor
gives a fairly detailed appreciation of the enormous
body of new information which has become available
over the intervening decade.
ICES Cooperative Research Report, 205 was initiated by
the ICES Larval Ecology Working Group to bring together
the existing data on early life stages of cod and
haddock in 1987, using a checklist which was circulated
to Working Group members and participants at the ICES
Symposium on The Early Life History of Fish held in
1988. The ICES Study Group on Cod Stock Fluctuations
(which became the ICES/GLOBEC Working Group on
Cod and Climate Change) also produced syntheses of information
on North Atlantic cod stocks (ICES CM
1990/G:50) and these two sources, plus a large amount
of additional material were published, together with
nearly 800 references and six summary tables.
The main purpose of this update is unchanged: to provide
information for comparative studies of cod biology and
population dynamics. The checklist used to elicit specific
information was only very slightly extended from the
original, to include some additional questions about migration
and adult growth. A copy of the checklist is included
at the end of this introduction.

2005CRRThe Annual ICES Ocean Climate Status Summary 2004/2005
275
1/2/2021 1:17 PMSøren Killerup Larsen
In almost all areas of the eastern and western North Atlantic during 2004, temperature and salinity in the upper layers remained higher than the long-term average, with new records set in numerous regions. There was isolated cooling off the eastern North American coast. In most areas the trend over the last decade (1994–2004) has been one of warming.
Figure 1 shows annual-mean normalised temperature and salinity anomalies for selected time-series in the upper layers of the ocean around the North Atlantic Region. The trends in these data over the past 10 years are illustrated in Table 1. Table 2 contains additional information about each of the time-series.
The North Atlantic Oscillation (NAO) index during the winter of 2004 was negative, but both the Iceland Low and the Azores High weakened. A mid-latitude low pressure anomaly associated with the reduced Azores High was stronger in the west, resulting in pressure anomaly patterns over the western North Atlantic consistent with a strongly negative NAO.

2005CRRThe intentional introduction of the marine red king crab Paralithodes camtschaticus into the Southern Barents Sea
277
1/2/2021 1:17 PMSøren Killerup Larsen
The red king crab (Paralithodes camtschaticus) was intentionally transferred from areas in the
Northern Pacific Ocean to the Russian Barents Sea during the 1960s (1961–1969), to create a
new and valuable commercial resource. A reproductive population in the receptor region was
evident ten years later and from this time the species has continued to spread both north and
east in the Barents Sea and southwards along the coast of Northern Norway. Ecological impacts
upon the native fauna are investigated through, among others, analysis of the diet of the
crab, as molluscs, echinoderms, polychaetes and crustaceans are frequently found as prey
items.
Problems following the invasion of the red king crab are displayed as bycatch of crabs in gillnet-
and longline-fisheries. The crab is regarded as a commercial resource both in Russia and
Norway. Management of the red king crab is undertaken as a joint stock between Norway and
Russia through the Joint Russian-Norwegian Fishery Commission.

2005CRRDescription of the ICES HAC Standard Data Exchange Format, Version 1.60
278
1/2/2021 1:16 PMSøren Killerup Larsen
The HAC standard format for the exchange of fisheries acoustics raw and edited data was
adopted by the ICES-Fisheries Acoustics Science and Technology Working Group
(WGFAST) in 1999. Since 2000, the ICES HAC Planning Group (PGHAC) has overseen
modifications and additions to the format so that it would evolve to meet the needs of the
international fisheries acoustics community. The present report is based on the original
adopted version and consolidates into one document the various additions, modification,
corrections and clarifications which have been vetted and accepted by the PGHAC in the
intervening years and published in the ICES Annual Reports of the Planning Group on the
HAC data exchange format. Through the work of the PGHAC, many improvements have been
made to the format, including the correction of errors and imprecisions in previously described
tuples, the clarification of rules and definitions for tuple syntax, for allocating tuple numbers
and for software compliance and compatibility, the addition of new tuples containing
information for a new generation of echosounders, for additional auxiliary sensors and for the
complete series of generic tuples for data exchange. The work of the PGHAC and the
evolution of the HAC standard format will continue after the publication of this document and
future modifications will continue to be published in the HAC Planning Group Annual
Reports.

2005CRRProtocol for the Use of an Objective Mesh Gauge for Scientific Purposes
279
1/2/2021 1:15 PMSøren Killerup Larsen
A mesh gauge developed by C. J. W. Westhoff under the auspices of the ICES Comparative Fishing Committee became the standard gauge for research activities in ICES countries in 1962 (ICES, 1962). In 1998/1999 the ICES Working Group on Fishing Technology and Fish Behaviour (WGFTFB) identified the need to refine mesh measurement methodologies to take account of the wider range of twines and netting types used in the netting industry since 1962. To deal with this request ICES adopted Council Resolution 1999/2B02 and established the Study Group on Mesh Measurement Methodology (SGMESH) under the Fisheries Technology Committee.
SGMESH was active from 2000 until 2003 and reported its findings and recommendations in ICES Cooperative Research Report No. 266 (Fonteyne and Galbraith, 2004). The Study Group recommended that all parties concerned should adhere to the specifications defined in the report, whether they are scientists, fisheries inspectors, netting manufacturers, or fishers. As advice derived from selectivity data determines mesh size regulations, it is logical that all stakeholders should use the same system of mesh measurement. The principle of using a longitudinal measuring force to stretch the meshes (as in the ICES Mesh Gauge) was maintained but the measuring force was changed from 4 kgf to 40 N or 100 N, depending on whether the mesh opening is smaller than 55 mm or equal to or larger than 55 mm. Until an instrument capable of making objective measurements, not subject to human influence, with the new measuring forces became available, SGMESH recommended that for scientific purposes the existing ICES gauge with 4 kgf measuring force was to be used and that a conversion formula should be applied to deliver a mesh opening equivalent to that obtained using a force of 100 N.

2006CRRIncorporation of process information into stock-recruitment models
282
1/2/2021 1:12 PMSøren Killerup Larsen
In 1999, the ICES Oceanography Committee (OCC) supported the creation of an ICES expert
group to investigate the separation of environmental influences from underlying stock–
recruitment relationships. The ICES Study Group on the Incorporation of Process Information
into Stock–Recruitment Models (SGPRISM) was formed and so afforded an opportunity for
biologists and stock assessment practitioners to meet under a common theme and to begin the
much-needed process of integrating biological knowledge and stock assessment methods and
techniques.
This ICES Cooperative Research Report represents a synthesis of the work from the three
SGPRISM meetings, held in 1999, 2001, and 2002 (ICES, 2000, 2001, and 2002). The list of
participants and their attendance appears in Section 12. The group’s terms of reference (ToRs)
appear in Annex 1.
The study group’s first meeting (ICES, 2000) concentrated on such environmental issues as
drivers of recruitment variability. The second meeting considered both possible environmental
and biological causes of recruitment fluctuations (ICES, 2001). The third meeting (ICES,
2002) focused on developing modelling and stock assessment tools.

2007CRRAlien Species Alert: Undaria Pinnatifida (Wakame or Japanese Kelp)
283
1/2/2021 1:11 PMSøren Killerup Larsen
Since the early 2000s, the Japanese kelp, Undaria pinnatifida, native to the northwest Pacific,
occurs on all continents except – so far – Africa and Antarctica, and it has become one of the
main target species for biosecurity. In an analysis ranking species traits of 113 introduced
seaweeds in Europe, it was the third most invasive seaweed. There are several reasons for its
success as an invader, especially its great ability to colonize artificial substrates and disturbed
areas rapidly, as well as shells of oysters and mussels, and it can grow very fast, reaching
lengths of up to 2–3 metres. Other reasons are its high tolerance for adverse conditions, such
as high turbidity and eutrophication, and the nearly invisible gametophytes’ ability to survive
being out of water for more than a month and act as a “seed bank”. The reproductive output is
large, and zoospores may be released all year-round, which contributes to its colonization
potential. Further, Undaria often develops into a fouling problem. This not only affects ships
and boats, but also structures used in aquaculture and molluscs growing on the seabed. On the
other hand, it has economic value as a source of food (“wakame”), which has been the
motivation for intentional introductions to some areas for farming.
In the early 1970s, it made its first appearance on another continent as an unintentional
introduction with oysters that were brought from Japan to the French Mediterranean coast. In
the early 1980s, it was intentionally introduced from the Mediterranean Sea for farming in
Brittany, northwestern France, from where it later dispersed to other northern European
countries. In the late 1980s, it was recorded both in New Zealand and Australia, having been
brought by shipping from Asia, which also was the vector for its spread to Argentina in the
early 1990s. Thus, the main vectors for unintentional introductions have been ships or small
boats as well as oyster movements in aquaculture (including illegal ones).

2007CRRStatus of Introductions of Non-Indigenous marine species to North Atlantic waters and adjacent waters, 1991-2002. (Ten year summary of national reports considered at meetings of the Working Group on Introductions and Transfers of Marine Organisms
284
1/2/2021 1:11 PMSøren Killerup Larsen
As an intergovernmental organization on marine research that also deals with fisheries, ICES
was confronted early on with issues related to the introductions of non-indigenous species,
particularly diseases and parasites transferred with live transport of fish and shellfish for
relaying, stocking, ranching, and for fresh fish markets. During the late 1960s and early 1970s,
a primary concern was the need to assess the risks associated with deliberate transfers of
species. As a result, the Working Group on Introductions and Transfers of Marine Organisms
(WGITMO) was launched, meeting for the first time in Convy, Wales, 4 April 1979. Since
then, the working group has met almost annually, with its 25th anniversary meeting held in
Vancouver, Canada in 2003.
The first status report prepared by WGITMO on introduced species in the North Atlantic and
its adjacent waters appeared in 1980. The second report, Status of Introductions of Non-
Indigenous Marine Species into North Atlantic Waters 1981–1991, was published as ICES
Cooperative Research Report No. 231 in 1999. The present report continues the earlier efforts
and summarizes species introductions as reported during WGITMO meetings 1992–2002
(Table F1). The list of participants at the meetings considered here is provided in Annex 1.
The national reports received during the reporting period (Table F2) were considered in detail
in the preparation of this report. It should be noted that attendance at WGITMO meetings was
not continuous for all ICES member countries. Canada, England and Wales, Ireland, Sweden,
and the US delivered national reports to all meetings. Non-ICES member countries such as
Australia and Italy also provided comprehensive information on introduced species.

2007CRRResults of the spring 2004 North Sea ichthyoplankton surveys. The distribution of fish eggs and larvae from the international ichthyoplankton survey
285
1/2/2021 1:06 PMSøren Killerup Larsen
A key recommendation of the meeting of scientific experts, which accompanied the Fifth International Conference on the Protection of the North Sea, 20-21 March 2002, Bergen, Norway, was that there should be regular monitoring of the spawning grounds of important commercial fish species. Up to this point there had never been a comprehensive survey of spawning grounds covering the whole North Sea. The problem was seen as particularly pressing in relation to cod, where a lack of up-to-date information hampered the design of suitable protection measures. In response, ICES set up a planning group (PGEGGS) to review whether a complete North Sea survey targeting eggs and larvae would be feasible. Planning took several years owing to the complex international nature of the problem, but in late 2003 and early 2004, ichthyoplankton surveys covering the whole North Sea were conducted to comprehensively assess the spawning areas of cod and plaice. The survey itself was titled PLACES (Plaice and Cod Egg Survey) to distinguish it from the work of the planning group (PGEGGS). A group of international research institutes took part from England, the Netherlands, Germany, Denmark, and Norway. Subsamples of eggs that were “cod-like” in appearance were presorted from samples at sea and preserved in ethanol for analysis using species-specific genetic probes. The remainder of each sample was preserved in formalin, and the ichthyoplankton were identified later, using traditional visual methods. A full account of the material and methods used, plus initial results of the distributions of cod and plaice spawning, can be found in Fox et al. (2005a). Details of the molecular methods used to identify cod-like eggs are reported in Taylor et al. (2002). For the cod-like eggs, proportions were assigned, based on the genetic results at each station, but these results are not presented here. This report presents the distributions and abundances of eggs and larvae of the other species identified from the survey series.

2007CRRAcoustic seabed classification of marine physical and biological landscapes
286
1/2/2021 1:06 PMSøren Killerup Larsen
The natural world is structured hierarchically, and processes within natural regions operate
across a number of spatial and temporal scales (Turner et al., 2001). Managing marine
ecosystems requires that natural regions be identified and mapped over a range of
hierarchically nested scales, and management of resources across multiple spatial scales
requires a classification system. The development of classification schemes is an active area of
marine research. The EUNIS (European Nature Information System) classification scheme is
being developed and managed by the European Topic Centre of Nature Protection and
Biodiversity (ETC/NPB in Paris) for the European Environment Agency (EEA) and the
European Environmental Information Observation Network (EIONET; Davies and Moss,
1999). Alternatively, top–down habitat classification schemes have been developed for global
applications in the management of marine resources (e.g. Greene et al., 1999; Valentine et al.,
2005). The further development and application of these classification schemes require
explicit information that characterizes marine habitats on a variety of spatial scales. Acoustics
is increasingly regarded as the remote-sensing tool that will provide the basis for classifying
and mapping ocean resources. Existing acoustic systems can measure seabed sediment
properties and bedform morphology from scales of centimetres to kilometres.

Acoustic data from fishing vessels provide a valuable source of information for fishery
management. To maximize the utility of fishing vessel acoustic data, objectives must be
clearly defined in the context of the potential impact on the management of the fishery and the
overall input to the ecosystem approach to fishery management. This can be achieved through
a qualitative or quantitative evaluation of all monitoring needs within the fishery, through a
monitoring strategy within a harvest strategy to explore the sampling needs, and necessary
accuracy and precision to meet management objectives.

The ICES Study Group on the North Sea Benthos Project 2000 undertook to integrate recent
(1999–2002) macrobenthic infaunal and environmental data from various national sources.
The main aim was to compare the outcome with that of the ICES North Sea Benthos Survey
conducted in 1986, to identify any significant changes and their likely causes.
In the process, the exercise yielded valuable lessons for the conduct of international
collaborative programmes, as well as insights into the utility of a range of interpretational
tools. These are timely in view of increasing requirements for periodic, sea-wide assessments
of quality status to meet international obligations, such as those under OSPAR, ICES,

This report describes the present (2006) status of sea temperature and salinity in the ICES region of the North Atlantic and Nordic Seas, as well as trends observed. Some additional datasets are provided, including those on sea level pressure, air temperature, and ice cover. Although the focus is on the variations in the upper ocean (the top 1000 m),
information about changes in the deeper layers of the ocean is also included in specific regions of interest.
A new edition of the report is published annually in the ICES Cooperative Research Report series.
The North Atlantic region is unusual in having a relatively large number of locations at which oceanographic data have been collected for several years or even decades. The longest records go back more than a century. In this report, we provide the very latest information from places where the ocean is currently being measured regularly. Although the North Atlantic is rich in measurements compared with other parts of the global ocean, there is still only a thin scattering of long records of deep ocean measurements. In the first part of the report, we draw together the sparse information and give the best possible overview of the region. Numerical models using real ocean measurements to simulate variations over time are continually being improved. In future editions, we hope to develop this part of the report to present the new information provided by the combination of models and data.

1/2/2021 12:58 PMSøren Killerup Larsen
The primary purpose of this document is to report the recommendations resulting
from the ICES WORKSHOP ON THE SIGNIFICANCE OF CHANGING OCEAN CO2 AND PH IN
ICES SHELF SEA ECOSYSTEMS held between 2 and 4 May 2007 in London. Some excellent
reports have already been published in this field, first by the Scientific Committee
on Oceanic Research (SCOR; Arvidson, 2005), then by the National Oceanic and
Atmospheric Administration/National Science Foundation/US Geological Survey
(NOAA/NSF/USGS; Kleypas et al., 2006), the Royal Society (The Royal Society, 2005),
the German Advisory Council on Global Change (WBGU; WBGU, 2006), and most
recently by the OSPAR Commission (OSPAR, 2006) and the Intergovernmental Panel
on Climate Change (IPCC; Metz et al., 2005). Cognizant of these recent efforts, the
ICES Workshop set out with a slightly different aim to investigate the links between
potential changes in pH and its effects on marine ecosystem components, such as
plankton, fish and shellfish, and cold‐water corals. To this end, the Workshop covered
ground already considered by others, to provide a sound base for the prediction
of likely impacts. The present report will outline those relevant issues, but the reader
is advised to refer to other reports for greater detail. The novel focus of this report is
the potential effects on ecosystem functions with links to fisheries, with a recommendation
for work to be done to better understand the impact of this problem on the
entire ecosystem, and specifically on fisheries. Most of the material used was presented
at the Workshop, with Annex 1 being the most significant exception.

In this section, we summarize the conditions in the upper layers of the North Atlantic during 2007, using data from a selected set of sustained observations and additional data products (gridded sea surface temperature (SST) data and summaries from ARGO floats).
Where in situ data are presented in the summary tables and figures, normalized anomalies have been presented to allow better comparison of trends in the data from different regions (Figures 1–3; Tables 1 and 2). The anomalies have been normalized by dividing the values by the standard deviation of the data during 1971–2000. A value of +2 thus represents data (temperature or salinity) at 2 standard deviations higher than normal.
Sea surface temperatures across the entire North Atlantic have also been obtained from a combined satellite and in situ gridded dataset. Figure 3 shows the annual and seasonal SST anomaly for 2007, extracted from the Optimum Interpolation SSTv2 dataset provided by the NOAA-CIRES Climate Diagnostics Center in the US. In high latitudes where in situ data are sparse and satellite data are hindered by cloud cover, the data may be less reliable. Regions with ice cover for >50% of the averaging period are left blank.
Maps of temperature, salinity, and winter mixed-layer depth in the North Atlantic have been prepared using in situ data including the newly expanding dataset from the ARGO float programme. The upper layer temperature anomalies for 2007 compare well with those obtained using OISSTv2 data (Figure 1). These maps (Figures 4 and 5) offer a more detailed overview of conditions than can be obtained from satellite observations and provide the spatial context to compare with the in situ time-series.

1/2/2021 12:44 PMSøren Killerup Larsen
This is the seventh summary of zooplankton monitoring in the ICES Area and expands on previous reports with improved analysis, data, and presentation. This year’s report includes eight new monitoring sites: five from the western North Atlantic, two from the northern Baltic, and one from the northern Skagerrak. For each of the 37 zooplankton monitoring sites (Figure 1), WGZE has continued to seek out and include co-sampled temperature and chlorophyll data, as well as any available phytoplankton and nutrient data.
Although this report follows the structure of previous reports, it now features a new “standardized” graphical visualization for each site. This new presentation quickly summarizes the seasonal cycle and interannual variability of the zooplankton at each site and offers a quick overview of zooplankton interactions and/or synchrony with other co-sampled biological and hydrographic variables at the site. Each site also includes a long-term assessment of the monitoring area through comparison with a 100-year record of sea surface temperature (SST) data and up to 60 years of continuous plankton recorder (CPR) zooplankton data (when available near that site). Finally, this report concludes with a basin-wide overview of SST, phytoplankton, and zooplankton across the entire North Atlantic, using data from the CPR surveys (Figure 2).
This year’s report also includes a brief introduction to six Mediterranean zooplankton monitoring sites (Figure 1, yellow stars), a tribute to our Mediterranean colleagues, as ICES and the Mediterranean Science Commission (CIESM) prepare for the October 2008 “Joint ICES/CIESM Workshop to Compare Zooplankton Ecology and Methodologies Between the Mediterranean and the North Atlantic” (WKZEM; www.wkzem.net)

2009CRRHake age estimation: state of the art and progress towards a solution
294
1/2/2021 12:43 PMSøren Killerup Larsen
Since 1992, northern and southern hake (Merluccius merluccius) stock assessments
have used age data based on otolith analysis. Age data for stock assessment is provided
by different institutions, which implies a quantification of age‐reading precision
to estimate assessment quality indicators. During this period, considerable effort
has been made to improve the precision of age data by means of successive agereading
calibration exercises, exchanges, and workshops in 1997, 1999, 2001, and
2004. This goal was partly achieved, and experts recently agreed on standard criteria
(Piñeiro and Saínza, 2003) that allowed an acceptable precision to be reached for ages
up to 3 years (Piñeiro et al., 2004). However, these criteria have never been validated,
and recent mark ‒ recapture experiments are not in line with ageing results based on
the standard criteria.
Given the impact of bias in age estimation on stock assessment results, consequent
management advice, and concern about the state of the hake stocks (ICES, 2007a,
2007b), a report on the current state of the art is needed. The main goal of this report
is to present a synthesis of the work carried out over the years by researchers involved
in providing age data for stock assessment, mainly on age‐reading calibration
exercises, and current knowledge regarding the growth and ageing of this species.
This report also includes recommendations for future work aimed at achieving validated
age‐reading criteria.

2009CRRManual of recommended practices for modelling physical-biological interactions during fish early life
295
1/2/2021 12:43 PMSøren Killerup Larsen
The objectives of this manual of recommended practices (MRP) are to summarize
appropriate methods for modelling physical – biological interactions during the early
life of fish, to recommend modelling techniques in the context of specific applications,
and to identify gaps in knowledge. This manual is intended to provide a reference
for early‐career modellers who are interested in applying numerical models to
fish early life and who would benefit from a summary of recommended practices for
coupled biological – physical models that incorporate predictions from threedimensional
circulation models to determine the transit of fish eggs, larvae, and juveniles
from spawning to nursery areas. For current practitioners of numerical modelling
in fish early life, the manual provides updates on latest techniques and areas in
need of further research. Although the manual focuses on finfish, many of the summarized
modelling techniques and recommended practices apply to modelling
planktonic organisms, including zooplankton and other meroplankton (e.g. molluscs
and crustaceans).
It is important to recognize that “best” modelling practices depend upon the objective
of the modelling exercise. In other words, no single model is appropriate to all applications.
Instead, model formulations are situation‐specific. Because methodologies
depend upon the goal of the endeavour, this manual includes an overview of basic
components of fish early life models and presents recommendations in the context of
three specific applications: adaptive sampling, connectivity, and recruitment prediction.
The first three sections (Section 1 – Hydrodynamic models, Section 2 – Particle tracking,
and Section 3 – Biological processes) summarize methodologies that are important
components of three‐dimensional models of the early life of fish. The next three
sections (Section 4 – Application 1: adaptive sampling, Section 5 – Application 2: connectivity,
and Section 6 – Application 3: recruitment prediction) discuss the application
of selected methodologies to specific issues that are commonly addressed with
these models. The final section summarizes the information gaps and research needs
identified throughout the manual.
This MRP grew out of participant discussions at the “Workshop on Advancements in
Modelling Physical – Biological Interactions in Fish Early Life History: Recommended
Practices and Future Directions” (WKAMF) held on 3 – 5 April 2006 in Nantes, France.
This manual does not contain an exhaustive review of all approaches to modelling
the early life of fish. Instead, it is intended to be a general reference for fish early life
modelling that includes citations that will direct readers to in‐depth treatments of
specific topics. In addition, it should be noted that this document does not represent
the consensus recommendations of all authors. Each section was written separately.
In some cases, differences in recommendations and perspectives exist. These apparent
contradictions may stem from dissimilarity in the time or space scale of the models
used by the authors or the ecosystem in which the authors are most experienced
(e.g. temperate vs. tropical). The issues on which recommendations or perspective
diverge are those that remain an active area of research. This manual is a “living”
document: future revisions and updates are expected as our understanding and
methods evolve.

2009CRRDefinition of standard data-exchange format for sampling, landings, and effort data from commercial fisheries
296
1/2/2021 12:42 PMSøren Killerup Larsen
Standardization of data-exchange formats is a natural and necessary development of the increasing need for cooperation and integration of fisheries data between insti-tutes. However, the existence of several standards to report the same data is time consuming, threatens the quality of the information, and is frustrating for those in charge of reporting the data. In spite of such problems, data-exchange formats have proliferated in recent decades, driven by the need to fulfil specific tasks associated with research projects and/or expert groups.
The format described in this report became a de facto standard that emerged from a long development period and is now recognized informally by large parts of the fish-ery scientific community. On several occasions, it has proven to be efficient at ad-dressing different usages, particularly automated data exchange in distributed sys-tems and data warehousing.
This report will describe in detail the exchange format, providing information about its usage in distinct environments. Given the lack of formal methods for setting standards, publication by ICES in this series will make this available to the fishery com-munity. In Section 1.2, we elaborate on the principles that were adopted to de-velop a format that would meet the needs and compromises in the best and most en-during way possible.

2009CRREffects of extraction of marine sediments on the marine environment 1998-2004
297
1/2/2021 12:42 PMSøren Killerup Larsen
Each year across the ICES Area, approximately 53 million m 3 of sand and gravel are
extracted from licensed areas of the seabed as a source of aggregate for the construction
industry, either to supplement land‐based sources or as a source of material for
beach nourishment. Because planning constraints and resource exhaustion are tending
to restrict the extraction of sand and gravel (aggregate) from terrestrial sources,
attention is increasingly being focused on the importance of seabed resources to satisfy
part of the demand for aggregates. The seabed is also recognized as the only viable
source of material for beach recharge in coastal defence schemes. In recognition
of this, the exploitation of marine resources is supported in most ICES Member Countries
by national and international minerals policies, subject to environmental safeguards.
The use of marine resources reduces the pressure to work land of agricultural
importance or of environmental and hydrological value and, where materials can be
landed close to the point of use, an additional benefit is that long‐distance overland
transport is avoided. However, the benefits of using marine sand and gravel must be
balanced with the potentially significant environmental impacts.
The scale of marine aggregate extraction has increased in recent years. This rise reflects
the increasing constraints on land‐based extraction and the recognition that
controlled dredging is sustainable in the foreseeable future. Interest by the general
public in the effects of marine sand and gravel extraction on the environment and
fisheries has grown in line with this expansion of effort. Issues such as the potential
for conflict of interest between stakeholders in the resource and the efficacy of remedial
measures during and after extraction are analogous to those arising from landbased
activities. However, in the marine environment, their resolution is rendered
more difficult because of the relative inaccessibility of sites, the general paucity of
site‐specific data on the structure and functional role of the habitat and biota associated
with sand and gravel deposits, and problems in quantifying the performance of
local fisheries. Further core drivers for understanding the impacts of marine aggregate
extraction exist at the international level. In particular, there is an increasing focus
on the conservation of marine biodiversity, following the Rio Earth Summit, and
on the protection of marine habitats (under the EU Habitats Directive) of whole sea
areas through international management initiatives under OSPAR, HELCOM, and
the EU Marine Strategy Directive. OSPAR, HELCOM, and ICES are also promoting
transnational cooperation in developing the ecosystem approach to marine management.
Of particular relevance is the increasing emphasis in national and international
fora on the development of more holistic (ecosystem‐level) approaches to marine environmental
management, including evaluations of the scope for “cumulative” or
“in‐combination” effects.

2009CRRAlien species alert: Crassostrea gigas (Pacific oyster)
299
1/2/2021 12:41 PMSøren Killerup Larsen
The Pacific oyster (Crassostrea gigas, Thunberg, 1793) is one of 20 species in the genus
Crassostrea. Although native to the Japan/Korea region, C. gigas is a hardy species that
has been introduced to a number of countries worldwide, including the US, Canada,
the UK, France, Korea, China, New Zealand, Australia, South Africa, and South
America, mainly for aquaculture purposes (Mann et al., 1991; Orensanz et al., 2002).
As a result, C. gigas has become the leading species in world shellfish culture, with an
estimated production of 4.6 million t in 2006 (FAO, 2008). Because C. gigas does not
require additional food to sustain its growth, this species is relatively inexpensive
and easy to produce. Its capacity to adapt to various environmental conditions and
temperature fluctuations, coupled with its rapid growth and resistance to highly
turbid areas, contributes to its success.

The Gulf of Cadiz is strategically located, connecting the open Atlantic Ocean with
the Mediterranean Sea. The nutrient enrichment of local coastal waters is assumed a
consequence of discharge from the Guadalquivir River (Huertas et al., 2006) and the
Guadiana River (Chícharo et al., 2006; Cravo et al., 2006). Moreover, sea surface
temperature remote sensing and in situ temperature observations demonstrate the
occurrence of upwelling off the Algarve coast (Fiúza, 1983; Folkard et al., 1997), thus
contributing to the enrichment of the coastal water and providing a well‐diversified
plankton community within the Gulf of Cadiz. This local productivity in the coastal
areas of the Gulf of Cadiz is exported to other regions, namely the western basin of
the Mediterranean, assisted by Atlantic surface water entering through the Strait of
Gibraltar.
This continuous inflow of surface Atlantic water into the Mediterranean Sea has an
important influence on the ecology and hydrology of the western and eastern basins.
Andersen et al. (2001) suggested that relatively high zooplankton diversities in the
study zone of the western Mediterranean might be the result of exchange with the
Atlantic Ocean. This environment in general, and the Algarve coastal zone in
particular, has been scarcely studied from the physical ‒ planktonic coupling
perspective (García et al., 2002; Ruiz and García‐Lafuente, 2006), which contrasts with
the extensive oceanographic literature on the Strait of Gibraltar and the other adjacent
basin, the Alboran Sea (e.g. Gómez et al., 2001; Echevarría et al., 2002). This work is a
first attempt to characterize the mesozooplankton community in the Algarve coastal
zone and to help understand the dynamics of the Gulf of Cadiz planktonic
assemblages.

2010CRRResolving climate impacts on fish stocks
301
1/2/2021 12:39 PMSøren Killerup Larsen
Evidence is accumulating that the increase in CO2 is affecting the global climate, with
far‐reaching implications for biological processes and ecosystem services (IPCC,
2001). Marine capture fisheries yield ca. 85 million tonnes year −1 and provide an
economic basis for many communities, with a total value of US $50 billion. The
sustainability of the fisheries is being jeopardized by overfishing (Pauly et al., 1998;
Jackson et al., 2001; Jørgensen et al., 2007), but climate change may also affect the
productivity of fishery resources (Brander, 2005; Harley et al., 2006; Lehodey et al.,
2006).
The general concern about global warming and its effects has triggered a rapidly
increasing body of scientific literature, in which ecological time‐series are correlated
with environmental indicators (Drinkwater, 2005; Weijerman et al., 2005; Brunel and
Boucher, 2007). Recent studies suggest that there is evidence for a northward shift in
the distributional range of fish species (Quéro et al., 1998; Hiscock et al., 2001; Beare et
al., 2004; Perry et al., 2005) and changes in the productivity of commercially exploited
stocks (O’Brien et al., 2000; Brander, 2005), but the mechanisms underlying these
changes remain uncertain. Hence, it is largely unknown whether the observed
distributional shifts are caused by a relocation of the spawning and feeding grounds,
a change in the local survival of fish, or immigration into new habitats.

Over the past two decades, cephalopod molluscs have attracted increased attention
from marine biologists and fishery scientists. Several species are important for
European fisheries, as targets of small‐scale coastal fisheries and/or as bycatch in
multispecies fisheries for demersal fish. The present report draws on a series of
reviews prepared in 2005 for the CEPHSTOCK project (see Section 1). The taxonomy
of the main resource species is reviewed (Section 2), and brief descriptions of each
species are provided, along with information from studies of population genetics,
habitat requirements of paralarvae and adults, and health and ecotoxicology (Section
3). The main fisheries are described, including illustration of gears used in specialized
small‐scale fisheries and a discussion of the socio‐economic importance of the
fisheries. The current status of cephalopod aquaculture is reviewed, highlighting
notable advances in commercial culture of octopus and cuttlefish (Section 4). Current
fishery data collection and fishery management are described, noting that there is no
setting of landings quotas and no routine assessment of stock status. Options for
stock assessment are discussed, drawing on one‐off assessments made during specific
projects and current practice elsewhere in the world. The “live fast, die young” lifehistory
strategies of cephalopods present particular challenges, but parallels can be
drawn with short‐lived fish (Section 5). Finally, the report looks to the future,
reviewing possible effects of climate change on cephalopods. It discusses the future
development of aquaculture and fisheries for cephalopods, including prospects for
fishery forecasting and fishery management – especially in relation to the small‐scale
directed fisheries. Various knowledge gaps are identified, and ideas for research to
fill these gaps are presented.

2010CRRCod and future climate change
305
1/2/2021 12:37 PMSøren Killerup Larsen
As part of the ICES/GLOBEC programme on Cod and Climate Change (CCC), a
Workshop on Cod and Future Climate Change (WKCFCC) was held between 17 and
20 June 2008 in Copenhagen (ICES, 2008a). The objective was to develop projections
for the likely dynamics of Atlantic cod (Gadus morhua) over the next 20 – 50 years
based on (i) regional climate scenarios that included anthropogenic climate change,
and (ii) knowledge of the impact of climate on cod and other species gained during
the CCC programme. The projections would consider not only the direct climate
effects on cod, but also possible indirect climate effects resulting from changes in the
prey (including zooplankton), predators, and competitors of cod.
The development of reliable regional climate scenarios by downscaling (statistical or
coupled) from global circulation models (GCMs) depends on the overcoming of a
number of problems. Most existing downscaled scenarios are based on GCMs that
pre‐date the recent IPCC model runs (IPCC, 2007a). One regional model for the North
Sea was downscaled from a recent run; however, the IPCC GCM in question poorly
reproduced the current climate for the region, which calls into question the credibility
of regional downscaling. It was concluded that regional models should be
downscaled from several GCMs, chosen by their ability to reproduce the current
climate (not only temperature, but also wind and pressure fields, precipitation, etc.).
Because many of the IPCC 2007 model results demonstrate large deviations from
current regional climate observations, this limits the number of GCMs that can be
used for downscaling. Furthermore, the two major modes of variability over the
Atlantic Ocean during the past century, the Atlantic Multidecadal Oscillation (AMO)
and the North Atlantic Oscillation (NAO), are reproduced poorly by the GCMs
(Section 3.2). On an encouraging note, however, models that assimilate recent climate
data (and include the decadal modes) demonstrate useful forecasting skill, at least
over periods of a few years (Section 3.4).
Currently, the lack of reliable regional climate projections makes it unrewarding to
implement coupled biological models of lower trophic level dynamics impacts on cod
(Gadus morhua) populations for predictions over the next 20 – 50 years. Currently
available global and regional climate models are probably only adequate for
exploring impacts on the North Atlantic marine ecosystem in a preliminary way and
not for quantitative projections. Considerable scientific effort will be required to
design, initialize, run, and statistically test downscaled or fully coupled regional
models that are consistent with observed climate modes and data at global and
regional scales and that produce reliable output for the relevant variables affecting
biological systems. Impact assessments can, for now, be based on “what if” scenarios,
but the likelihood of these scenarios and the time‐scale over which they may occur is
not known.

2010CRRLife-cycle spatial patterns of small pelagic fish in the Northeast Atlantic
306
1/2/2021 12:36 PMSøren Killerup Larsen
The spatial organization of fish populations is expected to play a key role in population
dynamics and its response to environmental forcing. It has been argued (Sinclair, 1988) that
the size of populations and the spatial organization of their life cycles match key
oceanographic physical features in space and time. The characterization of a functional
linkage between key physical features and fish habitats was recognized as a first and
important step towards understanding the variability of spatial patterns and population
dynamics. Therefore, the 2004 – 2006 reports of the ICES Study Group on Regional Scale
Ecology of Small Pelagic Fish (SGRESP; ICES, 2004a, 2005, 2006a) attempted to characterize
patterns in the life‐cycle organization of fish stocks in the Northeast Atlantic and cross‐map
these with physical features. Results were consistent with previous findings.
In Sinclair’s (1988) perspective, physical retention explained maintenance of the life‐cycle
pattern, and vagrancy out of the pattern corresponded to losses to the population.
However, in this case, the maintenance of these patterns is explained by biological
behavioural processes and population substructure. This led to the recognition that habitats
are not necessarily occupied, even if they are potentially suitable, because of the history of
the population.
In this report, we document life‐cycle patterns and how they match physical features for
small pelagic fish stocks in the Northeast Atlantic. Species considered include herring
(Clupea harengus), sardine (Sardina pilchardus), sprat (Sprattus sprattus), anchovy (Engraulis
encrasicolus), mackerel (Scomber scombrus), and blue whiting (Micromesistius poutassou). For
each case study of a stock, a similar template was followed, and the knowledge compiled of
the stock’s biology, life‐cycle pattern, and past history, served as an “identity card” for the
populations. The template documents life history traits; habitats for all life stages
(spawning, feeding, wintering, and nurseries); migration patterns, including larvae drift;
long‐term trends in the population; potential environmental influences; and observed
changes (e.g. spawning, migration, and behaviour) in relation to climate or ecosystem
change (e.g. Baltic Sea). The proposed schematic representation of life‐cycle patterns
allowed the differentiation of the roles of different migratory components in structuring
life‐cycle patterns. It can also serve as a knowledge basis for spatial management.
Perspectives on continuing the work relate to habitat modelling, bioenergetics, behaviour,
and operational oceanography.

2011CRRICES Zooplankton Status Report 2008/2009EPDSG
307
1/2/2021 12:36 PMSøren Killerup Larsen
This is the eighth summary report of zooplankton
monitoring in the ICES Area. This year’s report
includes seven new survey sites: one in the western
North Atlantic (Site 9, Bermuda Atlantic Timeseries
Study, or BATS), two in the Baltic Sea (Site
19, Gulf of Finland; Site 23, the Baltic Proper), one
adjacent to the North Sea (Site 28, Loch Ewe), and
three along the west Iberian peninsula (Site 31,
Gijón; Site 33, Vigo; Site 34, Cascais). The total site
count has only increased from 37 to 40 from the last
report because four transect-based sites from the
previous 2008 report were combined into a single
site and summary section (e.g. Svinøy East and
Svinøy West are now summarized under Svinøy
transect, Site 13). This report summarizes the North
Atlantic Basin and its major subregions using these
40 zooplankton monitoring sites (Figure 1.1) as well
as the 40 Continuous Plankton Recorder (CPR)
standard areas (Figure 1.2).
Although this report follows previous reports in its
general structure and analysis, new standardized
data components and graphical visualizations have
been added. For example, each site report now
begins with a standard figure series demonstrating
the seasonal cycles of zooplankton, chlorophyll, and
temperature at that site. Multivariate figures then
provide a quick overview of zooplankton interactions
and/or synchrony with other co-sampled biological
and hydrographic variables available for the site.
Finally, a long-term assessment of each monitoring
area is made using a 100-year record of sea surface
temperature data and up to 60 years of CPR
zooplankton data (when available near that site).
The methods and data sources used for this report
are summarized in Section 2.

2011CRRSediment dynamics in relation to sediment trend monitoring
308
1/2/2021 12:34 PMSøren Killerup Larsen
This report discusses the underlying processes of sediment dynamics in the North
Sea, the Baltic Sea, and several estuaries in order to indicate the broad range of
conditions that exist within the ICES Area. It is important to be aware of these
processes when designing monitoring programmes in order to ensure that the data
collected can be the foundation of a more meaningful interpretation. This
introductory section does not seek to define which monitoring strategies should be
used, but demonstrates that it is necessary to consider the sediment dynamics present
in the area being studied when designing a monitoring programme.
Time‐trends in contaminant, nutrient, and carbon concentrations in sediments are
usually inferred from sediment cores or from surface sediments taken during
repeated sampling exercises. Physical, chemical, and biological processes, all
components of sediment dynamics, can affect the concentration of contaminants.
Physical processes include erosion, transport, deposition, and resuspension. These
processes are driven by various different forces, such as isostatic movement, tidal and
wind‐driven currents, and density currents. For example, in the Baltic Sea, increased
eutrophication may lead to deep‐water oxygen deficiency that subsequently causes
the creation of laminated sediments, and these apparently allow a strong down‐core
time‐control on contaminant input. However, these down‐core trends may be
distorted by several processes, including the increased input of clean sediment
resulting from increased wind‐driven erosion of glacial clays that are subject to
isostatic uplift. In the North Sea, the upper 10 cm of sediment in a sandy area may
reflect contaminant input during the most recent months, or even days, because of
the constant reworking of the sediment and potentially large bulk‐sediment
movement, while the upper 10 cm of sediment in a muddy depositional area with a
slow deposition rate may represent accumulation over the last 25 – 50 years or more.

1/2/2021 12:34 PMSøren Killerup Larsen
The main focus of the annual ICES Report on Ocean Climate (IROC) is the observed variability in the
upper ocean (the upper 1000 m), and the introductory section includes gridded fields constructed by
optimal analysis of the Argo float data distributed by the Coriolis data centre in France. Later in the
report, a short section summarizes the variability of the intermediate and deep waters of the North
Atlantic.
The data presented here represent an accumulation of knowledge collected by many individuals and
institutions through decades of observations. It would be impossible to list them all, but at the end of
the report, we provide a list of contacts for each dataset, including e-mail addresses for the individuals
who provided the information, and the data centres at which the full archives of data are held.
More detailed analysis of the datasets that form the time-series presented in this report can be found
in the annual meeting reports of the ICES Working Group on Oceanic Hydrography at http://www.

2011CRRICES status report on climate change in the North Atlantic

1/2/2021 12:33 PMSøren Killerup Larsen
Since 1990, when the First Assessment Report (FAR) of the Intergovernmental Panel
on Climate Change (IPCC, 1990) was published, literature on climate change has
grown exponentially. Nowadays, climate change is a challenging scientific issue that
has developed a body of observations, models, and hypotheses that is being used to
assess possible consequences for critical processes involved in the functioning of the
Earth. This progression has strongly influenced other disciplines, modifying
approaches to topics such as risk analysis, socio‐economics, ethics, politics, energy,
natural resource management, geo‐engineering, and even evolution. The scientific
debate has moved rapidly from observations to impacts to discussions of potential
mechanisms that may be used to mitigate and adapt to this new reality; a
development that reflects an urgent need to minimize the impacts of global warming
by taking action based on robust scientific knowledge.
In a succession of assessment reports, from the first to the fourth (FAR, SAR, TAR,
AR4; IPCC 1990, 1996, 2001, 2007a, respectively), the IPCC has played an essential
role in organizing data and synthesizing results published in a vast scientific
literature. Development of a comprehensive understanding of the ramifications and
implications of climate change for human society, and for the ecology and
sustainability of the entire planet, is only possible by adopting such an international,
integrated approach. However, the information published in the scientific literature is
often incomplete, local, and fragmented, and up to the most recent report (AR4) had
given only modest coverage to the oceans (Richardson and Poloczanska, 2008).
