The Norwegian fishery for saithe carried out in the Norwegian Sea, ICES Sub-areas I and II, within the Norwegian Exclusive Economic Zone is assessed as an environmentally responsible fishery by the Marine Stewardship Council. Increase the sustainability of the fish you eat from this area by choosing MSC Certified fish. Avoid eating immature saithe below about 60 cms and during its breeding time, January to March.
Coley or saithe belongs to the same family as cod and haddock. Coley usually enters coastal waters in spring and returns to deeper water in winter. They spawn from January to March at about 200m depth along the northern shelf edge and the western edge of the Norwegian deeps. Saithe can grow up to 130cm. It is a long-lived species and can reach ages of more than 25 years. They become sexually mature when 5-10 years old and 60-70cm long.
After a period of low stock size, the stock recovered during the 1990s. The spawning-stock biomass (SSB) has been above Bpa (220 k t) since 1996, declined considerably from 2007 to 2011, then increased again and is presently (2015) estimated to be well above Bpa. The fishing mortality (F) was below the Fpa from 1997 to 2008, started to increase in 2005 and was above Fpa from 2010 to 2012, but is now most likely to be below Fpa. ICES advises that in 2016 catches should be no more than 140,000 t (122,000 t in 2015; 140, 000 t in 2014; 164,000 t in 2013). Also bycatches of coastal cod and redfish (S. norvegicus) should be kept as low as possible. Bycatches of redfish in saithe fisheries are at unsustainable levels for this species.
There is a management plan for this fishery. A harvest control rule consistent with the precautionary approach to fisheries management was implemented in 2007. In 2013 the target level for fishing mortality was reduced. The Norwegian fishery for saithe, carried out in the Norwegian Sea, ICES Sub-areas I and II, within the Norwegian Exclusive Economic Zone, is assessed as an environmentally responsible fishery by the Marine Stewardship Council. The fishery is almost entirely (93%) Norwegian and managed by the Norwegian authorities.
Since the early 1960s, purse seiners and trawlers have dominated the fishery, with a traditional gillnet fishery for spawning saithe as the third major component. The gillnet fishery is the most intense during winter, purse seine in the summer months, while the trawl fishery takes place more evenly all year around. Norway accounts for more than 90% of the landings. Coastal cod and redfish are caught as bycatch in some saithe fisheries. The purse seine fishery is conducted in coastal areas and fjords. Slipping (a form of discarding) occurs in the purse seine fishery when saithe are caught below the legal minimum landing size. As a result, areas were closed and the MLS reduced from 42 to 40cms.
