Duri punggung (Keseluruhan (total)) : 0; duri punggung lunak (Keseluruhan (total)) : 98 - 110; Duri dubur: 0; Sirip dubur lunak: 73 - 85. Uniformly dark brown or black; young marbled or spotted with paler marks (Ref. 4705).
Body shape (shape guide): fusiform / normal.
Adults are benthic but occasionally pelagic (Ref. 4705). Feed mainly on other fishes (cod, haddock, pogge, sand-eels, herring, capelin), but also takes cephalopods, large crustaceans and other bottom-living animals. Batch spawner (Ref. 51846). Growth rate varies according to density, competition and availability of food. Slow growth rate and late onset of sexual maturity, halibut populations can be seriously affected by overfishing (Ref. 35388). Utilized fresh, dried or salted, smoked and frozen; can be steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988). Also Ref. 58426.
Males reach sexual maturity at 7-8 years and females at 10-11 years. Spawning happens from December to April, near the bottom (300 to 700 m), at temperatures between 5 and 7°. Egg size 3.0-3.8, larval size at hatching 6.5 mm (Ref. 4705).
