生態学
海 底生の; 深さの範囲 18 - 1075 m (Ref. 58452), usually 70 - 400 m (Ref. 35388). Temperate; 76°N - 18°N, 30°W - 42°E (Ref. 58452)
Eastern Atlantic: Norway and Iceland, southward to Mauritania. Also in the Mediterranean Sea and along the southern coast of the Black Sea.
Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm 42.3, range 20 - 70 cm
Max length : 140 cm TL オス/雌雄の選別がない; (Ref. 1371); common length : 45.0 cm TL オス/雌雄の選別がない; (Ref. 1371); 最大公表体重: 15.0 kg (Ref. 1371); 最大記録サイズ: 20 年 (Ref. 35388)
背面の脊椎 (合計): 0; 背鰭 (合計): 43-51; 臀鰭: 36 - 40. Inside of mouth and branchial cavity black. Second dorsal and anal fins notched. First vertebra and neural spine attached to skull. Vertebrae 50-52.
Minimum depth from Ref. 128002. Found usually between 70 and 370 m depth. Adults live close to the bottom during day-time, but move off-bottom at night. Adults feed mainly on fish (small hakes, anchovies, pilchard, herrings, cod fishes, sardines and gadoid species) and squids. The young feed on crustaceans (especially euphausiids and amphipods). Are batch spawners (Ref. 51846). Almost entirely marketed fresh, whole or filleted, to specialized restaurants or retail markets (Ref. 58452). Utilized fresh, dried or salted and frozen; can be steamed, fried, microwaved and baked (Ref. 9988). Stocks seem to be over-fished (Ref. 35388).
