Maturity: Lm 34.9 range ? - ? cm
Max length : 112 cm TL 雄鱼/尚未辨别雌雄; (Ref. 5951); common length : 35.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 4645); 最大体重: 16.8 kg (Ref. 9988); 最大年龄: 20 年 (Ref. 4645)
背棘 (总数): 0; 臀棘 0. Mouth relatively small; lower jaw shorter than the upper jaw; chin barbel rather small. Lateral line dark, uninterrupted to about the end of the body. Lateral-line pores present on head. Scales overlapping. A large dark blotch is above the pectoral fin just below the lateral line.
嘴相当小的; 下颌短于上颌; 下巴触须相当小。 侧线黑的, 不间断的到大约身体的末端。 侧线孔位于头部之上。 鳞片部分重叠的。 一个大的黑色斑块在侧线正下方是上方胸鳍。
Adults are found more commonly from 80 to 200 m, over rock, sand, gravel or shells, usually at temperatures between 4° and 10°C. Feed mainly on small bottom-living organisms including crustaceans, mollusks, echinoderms, worms and fishes (sand lance, capelin, silver hake, American eels, herring and argentines) (Ref. 5951). A batch spawner (Ref. 51846). Undertakes extensive migrations in the Barents Sea and Iceland. Sold fresh, chilled as fillets, frozen, smoked and canned. Also utilized for fish meal and animal feeds. Can be steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988).
从 80 到 200 公尺更通常发现,在岩石，沙子，砾石或贝壳之上, 通常在 4个 ° 与 10个 ° C. 之间的温度 主要吃包括甲壳动物，软件动物，棘皮动物，蠕虫与鱼的小型底栖性生物。 在巴伦支海与冰岛中进行广泛的回游。 生鲜贩卖了, 冷冻的如被冻结, 烟熏而且装于罐头的鱼排。 也利用鱼粉与动物饲料。 能被蒸,油炸,火烤, 煮沸, 微波而且烧烤。 (参考文献 9988)
