Sustainability overview

This stock was below Blim (lowest possible level of 21,000) for several years, but has now increased to above MSY Btrigger. Fishing pressure however remains too high.

Biology

Cod belongs to a family of fish known as gadoids, which also includes species such as haddock, pollack, pouting and ling. It is a cold-temperate (boreal) marine, demersal (bottom-dwelling) species. Also found in brackish water. Their depth range is 0 - 600 m, but they are more usually found between 150 and 200 m. They have a common length of 100 cm. Maximum length 200 cm. Maximum published weight 96 kg and a maximum reported age of 25 years. In the North Sea cod mature at 4-5 years at a length of about 50 cm. They spawn in winter and the beginning of spring from February to April. Fecundity ranges from 2.5 million eggs in a 5 kg female to a record of 9 million eggs in a 34 kg female. Sex ratio is nearly 50%, with slight predominance of females. The fish has a protruding upper jaw, a conspicuous barbel on the lower jaw (used to look for food), and a light lateral line, curved above the pectoral fins. Widely distributed in a variety of habitats, from the shoreline down to the continental shelf. Juveniles prefer shallow (less than 10-30 m depth) sublittoral waters with complex habitats, such as seagrass beds, areas with gravel, rocks, or boulder, which provide protection from predators. Adults are usually found in deeper, colder waters. During the day, cod form schools and swim about 30-80 m above the bottom, dispersing at night to feed.

Stock Area

Faroe Plateau

Stock information

Two distinct stocks are recognised in the Faroes. On the Faroes Plateau the spawning-stock biomass (SSB) was below Blim for several years, but has now increased to above MSY Btrigger (a biomass reference point that triggers a cautious response to reduce fishing mortality to allow a stock to rebuild) in 2018. Fishing mortality (F) has decreased since 2010 and is now close to FMSY. The 2009-2015 year classes are estimated to be below average size. The 2016 and 2017 year classes are estimated to be above average, though uncertainty is large.
ICES advises that when the MSY approach is applied, catches in 2019 should be no more than 10 180 tonnes.

Management

Criterion score: 0.75 info

There is no management plan for this stock. A preliminary management plan, including a recovery plan, was formulated in 2011, but has not been implemented. An effort management system has been in place from 1996 to 2018. A new management system will be implemented for cod, haddock, and saithe after 1 January 2019. This management system operates with catch quotas for large vessels (trawlers and longliners), whereas it operates with fishing days for the small vessels (mainly longliners). The catch quota for the small vessels needs to be converted into fishing days.

Capture Information

Criterion score: 0 info

Cod are mainly taken in a directed cod and haddock fishery with longlines (38% in 2017; 58% in 2016; 62% in 2015), in a directed jigging fishery (9% in 2017; 10% 2016), and as bycatch in the trawl fishery (53% in 2017; 32% in 2016) for saithe.
