laut bentopelagis; oceanodromus (Ref. 51243); kisaran kedalaman 1 - 2200 m (Ref. 108960), usually 500 - 1000 m (Ref. 6263). Boreal; -1°C - 4°C (Ref. 43586); 79°N - 33°N, 180°W - 180°E (Ref. 54862)
Circumglobal: In arctic and temperate waters; northern hemisphere. Sea of Japan off Honshu north to Shishmaref, Alaska in the Chukchi Sea, throughout the Aleutian Islands, and southeast to northern Baja California, Mexico. North Atlantic: New Jersey, USA to Spitsbergen (Svalbard Islands) and the Barents Sea south to Ireland. Northwest Atlantic: Canada (Ref. 5951).
Length at first maturity / Size / Weight / umur
Maturity: Lm 63.5, range 65 - 80 cm
Max length : 110 cm TL jantan/; (Ref. 80637); 130.0 cm TL (female); common length : 56.0 cm FL jantan/; (Ref. 55110); Berat maksimum terpublikasi: 7.0 kg (Ref. 173); Berat maksimum terpublikasi: 7.0 kg; Umur maksimum dilaporkan: 36 Tahun (Ref. 117245)
Duri punggung (Keseluruhan (total)): 0; duri punggung lunak (Keseluruhan (total)): 83-108; Duri dubur 0; Sirip dubur lunak: 62 - 79; vertebrata, bertulang belakang: 60 - 64. Dorsal origin behind posterior edge of upper eye. Caudal slightly forked to truncate. Pectorals small.
Often caught pelagically (Ref. 4705). Adults prefer bottom temperatures of -0.5°C to 6.0°C (Ref. 5951). Epibenthic (Ref. 58426). Feed on crustaceans, fishes (Ref. 4705, 6885), eelpouts, capelin, redfishes, deep sea prawns and other bottom invertebrates (Ref. 35388). Batch spawner (Ref. 51846). Utilized dried or salted and frozen; can be steamed and fried (Ref. 9988). Size of the Greenland halibut collected from 400-599 m deep in eastern Bering Sea, ranged from 9 to 99 cm FL with a mean of 56 cm (Ref. 55110).
Fertilized eggs develop in approximately 50 days. Larvae are pelagic with a maximum size of 8 cm and will drift for about 4 months before settling at about 7 cm on clay-silt subtrates at depths of 300-450 m, after which they metamorphose (Ref. 117245).
