Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 83 - 108; Épines anales: 0; Rayons mous anaux: 62 - 79; Vertèbres: 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).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larves

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).
