Sustainability overview

The stock in this area is above target or healthy and fishing mortality at an appropriate level. Avoid eating immature saithe below about 60 cms and during its breeding time, January to March. The best choice for saithe from this area is MSC Certfied fish. Look for the blue tick logo on the packaging.

Biology

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.

Stock information

The spawning-stock biomass (SSB) has been above MSY Btrigger since 1998 and is currently near the time-series maximum. The harvest rate (HR) has declined from 2009 and is presently below HRMSY. Recruitment (R) has been fluctuating and the average of the year classes 2006-2012 is estimated to be well above the average seen since 1980. The reference biomass (B4+) has increased since 2015 due to the 2012 year class, that is estimated to be strong. ICES advises that when the Iceland management plan is applied, catches in the fishing year 2017/2018 should be no more than 60 237 t (55,000 t in 2015/16; 58,000 t in 2014/15; 57,000 t in 2013/14; no more than 49,000 t in 2013).

Management

In spring 2013 the Icelandic Government adopted a management plan in accordance with the MSY approach for managing the Icelandic saithe fishery. The fishery was certified by the Marine Stewardship Council (MSC) as a sustainable fishery in September 2014.

Capture Information

Saithe in this area are caught in directed saithe fisheries as well as in mixed fisheries which target cod. The fishery is predominantly a bottom trawl (87%) one. Fishing is prohibited in areas where high concentrations of juveniles are found. Historically, coley has been one of the most important commercial species in Icelandic waters, with landings of between 30,000t to 130,000t. Discard bans and mandatory Bycatch Reduction Devices (BRDs) mean bycatch and discards are not an issue in this fishery.
