生態学
海 底生の漂泳性; 海洋回遊性 (Ref. 51243); 深さの範囲 50 - 300 m (Ref. 54932), usually 100 - 200 m (Ref. 54932). Temperate; 79°N - 48°N, 27°W - 30°E (Ref. 54932)
Northeast Atlantic: southwest Barents Sea, sometimes at Bear Island, south to the English Channel, - and the Bay of Biscaye (Ref. 90172)-, around Iceland and Faeroe Islands.
Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm 14.0, range 11 - 15 cm
Max length : 35.0 cm TL オス/雌雄の選別がない; (Ref. 1371); common length : 19.0 cm TL オス/雌雄の選別がない; (Ref. 4645); 最大記録サイズ: 5 年 (Ref. 273)
背面の脊椎 (合計): 0; 肛門の骨 0. Gray-brown dorsally, silvery on sides, white on belly. A dark blotch is at the upper edge of the pectoral-fin base.
Benthopelagic to pelagic over muddy bottoms. Mostly found between 100 and 200 m. Feeds mostly on planktonic crustaceans (copepods, euphausiids, shrimps, amphipods) but also on small fish and various eggs and larvae (Ref. 1371). Caught mainly for reduction to fishmeal (Ref. 3383), trout pellets, fodder (Ref. 35388).
Life cycle and mating behavior

Oviparous, sexes are separate (Ref. 205). Migrates for spawning between the Shetland Islands and Norway and out of the Skagerrak. Major spawning grounds are Northwestern Scotland, Norway, Faeroe Islands and Iceland.
