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.
東大西洋: 巴倫支海,斯匹次卑爾根群島到比斯開灣, 冰島的周圍。 西大西洋: 格陵蘭西南部,哈得遜海峽到北卡羅萊那州, 雖然稀有的在範圍的極端。 迴游進行產卵被知道出現。 也對於歐洲與美國的長途南北迴游。

生物学特性     字汇 (例如 epibenthic)

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).

一个活跃又群居的鱼出现于沿海地区与外海水域。 通常在春天进入沿岸水域而且回到较深的水域冬天时。 (参考文献 9988) 在近岸水域的较小的鱼吃小型甲壳动物 (桡脚类的动物,片脚类动物, 磷虾) 与小鱼而较大的鱼主要捕食鱼。 生鲜使用, 乾燥或盐腌, 烟熏, 罐装及冷冻; 清蒸,油炸,火烤, 煮沸, 微波了而且烧烤了.(参考文献 9988)
