Additional informationThe Norway haddock is closely related to commercially important redfish species but exploitation is not widespread due to its small size. It is of minor commercial importance in Iceland. Despite this, due to the similar appearance of redfish species, catches are often grouped together as redfish (Barro, 2005). The Norway haddock is vulnerable as it displays low resilience, with a minimum population doubling time of 4.5 to 14 years (FishBase, 2000).
