Good Fish Guide
Cod, Atlantic Cod
This stock has shown some increase after reaching a historical low in 2007 but biomass is still below target and currently around the lowest possible level, Blim, of around 21,000 t.
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.
Two distinct stocks are recognised in the Faroes. On the Faroes Plateau the stock has shown some increase after reaching a historical low in 2007, but remains below MSY trigger (a biomass reference point that triggers a cautious response to reduce fishing mortality to allow a stock to rebuild) and around the Blim level since 2005. Fishing mortality although decreasing since 2010, is currently above Fpa and FMSY but below Flim. ICES advises that when the MSY approach is applied, fishing mortality in 2017 should be no more than 0.16
The introduction of a Harvest Control rule in 2009 has seen Spawning Stock Biomass rise. Restrictions on catches have resulted in 60% reduction in fishing mortality and 50% in harvest rate since 2000. A real-time closure system aimed at protecting juvenile fish has been in force since 1976. Fishing is prohibited, for at least two weeks, in areas where the proportion by number of small cod (< 55 cm) in the catches is observed by inspectors to exceed 25%. Since 1995, spawning areas have been closed for 2-3 weeks during the spawning season for all fisheries. This measure was aimed at protecting spawning fish. In 2005, the maximum mesh size allowed in gillnets was decreased to 20.3 cm (8 inches) in order to protect the largest spawners, but this mesh size ban was lifted in 2012. The mesh size in the codend in the trawling fishery was increased from 120 mm to 155 mm in 1977. Since 1998 the minimum codend mesh size allowed is 135 mm, provided that a so-called "Polish cover" is not used. The longline, handline and Danish seine fishery for cod in Iceland's EEZ was certified to the Marine Stewardship Council (MSC) standard as an environmentally responsible fishery in June 2011.
Cod are mainly taken in a directed cod and haddock fishery with longlines (62% in 2015), in a directed jigging fishery, and as bycatch in the trawl fishery for saithe.
