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.

Method: Bottom trawl (otter)
Certification: Marine Stewardship Council (MSC)
More infoNortheast Arctic (Barents and Norwegian Sea) - Wild-caught
Location: Certified fleets only
Capture methods: Bottom trawl (otter)
Certification: Marine Stewardship Council (MSC)
The population of coley, or saithe, in the northeast Arctic is abundant and fishing is within sustainable limits. Some appropriate management measures are in place. Most of the fishery is MSC-certified. However, management has not adequately addressed bycatch issues. Some Arctic saithe catches are by otter trawls, which have an unsustainable bycatch of endangered golden redfish.Rating last updated July 2023.
North Sea, West of Scotland and Rockall, Skagerrak - Wild-caught
Location: All areas
Capture methods: Bottom trawl (otter)
The population of coley, or saithe, in the North Sea, West of Scotland and Rockall, and Skagerrak is overfished and fishing pressure is too high. Management measures are in place and generally effective, although there is no specific management plan for this fishery. Most saithe catches are by otter trawls, which are likely to cause some damage to the seabed. Bycatch is moderate and may include vulnerable species such as blue and flapper skate, and cod.Rating last updated August 2025.

Northeast Arctic (Barents and Norwegian Sea) - Wild-caught
Location: All areas
Capture methods: Net (purse seine or ring)
The population of coley, or saithe, in the northeast Arctic is abundant and fishing is within sustainable limits. Some appropriate management measures are in place. However, management has not adequately addressed bycatch issues. Some Arctic saithe catches are by purse seine netting. This has low bycatch levels and is unlikely to have any habitat impacts.Rating last updated July 2023.

Location: Certified fleets only
Capture methods: Bottom trawl (otter)
Certification: Marine Stewardship Council (MSC)
The Faroes Grounds saithe stock is above target levels, however the stock is being fished above target levels and is subject to overfishing. Average catches have been within recommended limits in recent years. A new management plan was introduced in 2021. Most Faroese saithe is caught by trawling, which is likely to cause some damage to the seabed. Bycatch is moderate and may include vulnerable species including porbeagle and Faroese cod.Rating last updated December 2025.

More infoIceland - Wild-caught
Location: All areas
Capture methods: Bottom trawl (otter)
Certification: Marine Stewardship Council (MSC)
Icelandic coley, or saithe, is not in an overfished state. However, fishing pressure is slightly too high. There is a management plan in place, which has successfully reduced fishing pressure. Catch limits are set in line with scientific advice and are expected to keep the stock at target levels. All Icelandic saithe landed by the Icelandic fleet is MSC certified. Most catches are by otter trawling, which is likely to cause some damage to the seabed. Bycatch is moderate. There are a number of measures in place to mitigate impacts on species and habitats, but more needs to be done to ensure they are effective.Rating last updated July 2022.

Location: Certified fleets only
Capture methods: Bottom trawl (otter)
Certification: Marine Stewardship Council (MSC)
The population of coley, or saithe, in the North Sea, West of Scotland and Rockall, and Skagerrak is fully fished but not subject to overfishing. Management measures are in place and generally effective, although there is no specific management plan for this fishery.
