The Barents Sea and Lofoten region of the Arctic has a
long history of commercial fishery. It is one of the world’s most productive sea areas and a Lofoten export fishery is described in the Icelandic sagas, circa A.D. 870.
Fisheries data has been collected for the area since a grant to study
“the Lofoten cod” was issued in 1864. Today, the Arctic Fisheries Working Group (AFWG), ICES longest-running expert group, in existence since 1959, performs assessments to assist in the development of fishing quota advice in the
Arctic region of the Barents Sea and the Lofotens.
In the time since AFWG was established, the region has seen many changes. From the
introduction of the 200-mile fishing limit to warmer waters and retreating
winter ice cover under climate change.
For some Arctic-adapted species this has presented
challenges while species at the northern extreme of their range (including
cod) are benefiting from the current moderate warming and are expanding
northwards across the Barents Sea.
Throughout this, the aim of AFWG has been to support the development of advice
that results in healthy catches and stocks – a healthy stock is far more able
to withstand changing environmental conditions than one only slightly above
Most of our stocks are managed with agreed Harvest Control
Rules, which produce moderate fishing pressures leading to high stocks and good
catches. Alongside these are longstanding measures such as discard bans, gear
restrictions, and area closures.
The advice our assessments lead to also include the impact of variable
predation on the stocks - which we have been doing for capelin since 1991.
As the environment and the stocks continue to change, advice
and assessments will need to adapt. AFWG is therefore working with the ecosystem
monitoring group, Working Group on the Integrated Assessments of the Barents Sea
(WGIBAR), to ensure that our science adapts, and that we are able to continue providing
advice to support healthy robust fish stocks and fisheries in the Barents Sea
and the Lofotens.
The Arctic Fisheries Working Group (AFWG) performs assessments of cod, haddock, saithe, redfish, Greenland halibut, and capelin stocks in the Barents Sea and Norwegian Sea.
