Maturity: Lm 34.9 range ? - ? cm
Max length : 112 cm TL 雄魚/尚未辨別雌雄; (Ref. 5951); common length : 35.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 4645); 最大體重: 16.8 kg (Ref. 9988); 最大年齡: 20 年 (Ref. 4645)
背棘 (總數) : 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.
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).
Oviparous, sexes are separate (Ref. 205). Spawning occurs in typically marine waters between 50 and 150 m depth (Ref. 1371).
