البيئة
بحري القاع; محيطية (Ref. 51243); نطاق العمق 37 - 364 m (Ref. 5951). Temperate; 77°N - 33°N, 76°W - 35°E
Eastern Atlantic: Barents Sea, Spitsbergen to Bay of Biscay, around Iceland. Western Atlantic: southwest Greenland, Hudson Strait to North Carolina, although rare at the extremes of the range. Migrations for spawning are known to occur. Also long-distance north-south migrations for Europe and the US.

An active, gregarious fish occurring inshore and offshore waters. Usually enters coastal waters in spring and returns to deeper waters in winter (Ref. 9988). Smaller fish in inshore waters feed on small crustaceans (copepods, amphipods, euphausiids) and small fish, while larger fish prey predominantly upon fishes. Spawn in batches (Ref. 51846). Utilized fresh, dried or salted, smoked, canned and frozen; eaten steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988).
Oviparous, sexes are separate (Ref. 205).
