Species Information
Size Maximum size to 2 m and about 90 kg, but average size only around 60 cm with weights averaging about 2 to 3 kg in western Atlantic.
Diagnostic characters
Habitat, biology, and fisheries Primarily demersal, but becoming pelagic when feeding and spawning; found mostly over continental shelf in 150 to 200 m, but recorded to much greater depths (over 600 m). Prefers cold waters of 0 to 5 degrees C, but found in waters as warm as 15 degrees C. A species of considerable economic importance, 141M metric tons globally from 1950 to 2024, but stocks in western Atlantic severely depleted and commercial harvest for the most part curtailed. Marketed fresh, frozen, dried, salted, and smoked.
Distribution A boreal North Atlantic species ranging from North Carolina to Greenland, Iceland, across northern Europe, into Barents Sea including Novaya Zemlya and Spitzbergen; uncommon south of New York and New Jersey and of no commercial importance in Area 31.
