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.
成魚是底棲的但是偶然大洋性.(參考文獻 4705) 主要捕食其他的魚 (鱈魚，黑斑鱈， pogge, 沙子-鰻魚，鯡魚, capelin), 也捕食頭足類動物，大的甲殼動物與其他的底棲動物。 分批產卵者.(參考文獻 51846) 生鮮使用, 乾燥或鹽醃, 煙燻與冷凍的; 能被蒸,油炸,火烤, 煮沸, 微波而且燒烤。 (參考文獻 9988) 成長比率各種各樣的根據食物的密度，競爭與有效。 減慢成長率與性成熟的遲攻擊, 大比目魚族群能嚴重地被藉由捕撈過度影響 (. 參考文獻 35388) 也參考文獻 58426.
