WGPDMO Example is a composite from WGPDMO 2006 and 2009 reports.

The following data example describes a part of a hypothetical fish disease data submission.

The first number in each line denotes the record type. The biota specimen record (type
�04�) is the start of the information for an individual fish (or a pool of fish with all attributes
identical). Commas separate data fields. The example below describes information for 7 fish, where the
first two data blocks, each headed by a �04� record, describe individual fish which each were
examined for 3 diseases, while the third block describes a pool of 4 fish which were examined
for 2 diseases and the fourth block describes again one fish, but here disease grades are
reported instead of the pure presence/ absence information which was given for the first 6 fish.
All fish were Limanda limanda which is reported in a '03' sample record. The individual attributes reported by the data
lines below are:

fish 1 (subno 1): male, length 17 cm, examined for lymphocystis (found present), skin ulcerations
(absent) and epidermal hyperplasia / papilloma (absent),

fish 2 (subno 2): female, length 18 cm, examined for lymphocystis (found present), skin ulcerations
(absent) and epidermal hyperplasia / papilloma (present),

fish 3-6 (subno 3): 4 females, length 21 cm, examined for lymphocystis (found present), skin ulcerations
(absent). Note that pools may be formed only if, for each disease examined, the resulting number affected (AFNR)
in record type '10' is either zero or identical with NOINP from record type '04.'

fish 7 (subno 4): female, length 23 cm, examined for lymphocystis (absent), skin ulcerations (grade 3
found) and epidermal hyperplasia / papilloma (grade 1 found).

WGPDMO 2009 Rule for correct pooling of data

The fish disease data provided by the ICES Data Centre revealed a problem caused
by incorrect pooling of data. The mistake was that a pool was formed of fish with
different attributes, as illustrated in the first block (headed by a "04" record) of the
following fictitious example:

10,CEND7/04,77,1,3,EP,,,LYMP CYS,AFNR,,1,,,2,,,,,,

Boldface numbers in the type �"04" records show the number of fish in the pool
(NOINP), boldface number in the type �"10" records the number of affected specimen.
The first block tells that there were 4 fish, with in all 3 Skin Ulc observations and 2
Lymp Cys observations. Unfortunately, this block does not allow recognizing how
these diseases were distributed over the individual fish:

Ly Ul or Ly Ul
Ly Ul    Ly �-
-  Ul    -  Ul
-   -    -  Ul

The distinction between these two combinations and in general knowledge of the
combination of the diseases seen is crucial to evaluation and assessment. Therefore
the data from above should have been reported (depending on the real situation) as:

1) in the first situation

2) in the second situation

10,CEND7/04,77,1,3,EP,,,LYMP CYS,AFNR,,1,,,0,,,,,,

The rule for correctly pooling data are:
Pools may be formed only if, for each disease examined, the resulting number affected
(AFNR) in record type �e10�f is either zero or identical with NOINP from record
type �"04".
