There are several species of redfish in Norwegian waters. Golden redfish (Sebastes norvegicus), deep-sea redfish (Sebastes mentella) and Norway redfish (Sebastes viviparus). In addition, there is a separate population of beaked redfish in the Irminger Sea. This is composed of two pelagic populations that, with a certain overlap, are largely separated at depths.

Golden redfish

The golden redfish lives at 100–500 meters depth on the continental shelf, along the coast and certain places inside the fjords. It is widespread north/northwest of Spitsbergen, but is rarely found in fishable quantities north of Tromsøflaket/Bjørnøya.

Beaked redfish in the Barents and Norwegian Seas

Beaked redfish (Sebastes mentella) can be difficult to separate from golden redfish. However, it is usually smaller, growing rarely longer than 47 cm and then between 50 and 70 years old.

Beaked redfish in the Irminger Sea

These beaked redfish (Sebastes mentella) are a separate, oceanic and pelagic stock, probably a complex of two stocks between 100 and 900 m depth, over bottom depths of 1500–3000 m. These fish are slow-growing and late maturing and therefore highly sensitive to overexploitation.
