生态学
海洋 底中水层性; 海洋洄游的 (Ref. 51243); 深度上下限 0 - 868 m (Ref. 58496), usually 50 - 150 m (Ref. 4701). 3°C - 11°C (Ref. 127841); 80°N - 32°N, 95°W - 49°E
Western Atlantic: Nunavut, Hudson Bay to James Bay and Labrador in Canada to New Jersey in USA; rarely to Chesapeake Bay in USA and Bermuda. Eastern Atlantic: Barents Sea, Iceland and Greenland to Spain (Ref. 4701).
大小 / 重量 / 年龄
Maturity: Lm ? range ? - ? cm
Max length : 61.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 58426); 42.9 cm SL (female); 最大体重: 9.5 kg (Ref. 4701); 最大体重: 9.5 kg; 最大年龄: 13 年 (Ref. 54207)
背棘 (总数): 5 - 9; 背的软条 (总数): 9-11; 臀棘 0; 臀鳍软条: 9 - 10; 脊椎骨: 28 - 29. First dorsal fin present but covered by thick layer of skin forming a characteristic high crest with embedded spines. Bony tubercles present, arranged in 3 widely separated rows of large flattened tubercles on each side of body. Gill openings large, extend- extending below level of upper pectoral fin ray. Pyloric present 36-79. Ventral sucking disc formed by the modified pelvic fin (Ref. 232).
Basically solitary rather than a schooling fish. They exhibit a homing instinct (Ref. 9737). Adults inhabit rocky bottoms but may occur among floating seaweed. They migrate considerable distances in an annual cycle between deeper waters in winter and shallower waters in summer (Ref. 26141). Maximum depth reported at 868 m (Ref. 58426). Epibenthic-pelagic (Ref. 58426). Juveniles are found among algal clumps in bays and fjords moving offshore as they mature (Ref. 96431). During the spawning season the males become reddish in color on the underside, whereas females turn blue-green. Adults feed on ctenophores, medusas, small crustaceans, polychaetes, jelly fish and small fishes. Valued for their eggs, which make an inexpensive caviar (Ref. 9988). Eaten in Nordic countries, marketed fresh or smoked. Male flesh is most demanded and roe is sold fresh (Ref. 35388).
Life cycle and mating behavior

Eggs are laid in large numbers on stony bottoms (Ref. 9900). Male guards egg-mass aggressively.
