生態學
海洋 居於水底的; 海洋洄游的 (Ref. 51243); 深度上下限 37 - 364 m (Ref. 5951). ; 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.
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 39.1 range ? - ? cm
Max length : 130 cm TL 雄魚/尚未辨別雌雄; (Ref. 1371); common length : 60.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 4645); 最大體重: 32.0 kg (Ref. 7251); 最大年齡: 25 年 (Ref. 1371)
背棘 (總數) : 0; 臀棘: 0. Chin barbel small. Lateral line smooth along its entire length. Body color is brownish-green dorsally, becoming only slightly paler ventrally. The lateral line pale.
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).
