生態学
海; 汽水性の; 海洋回遊性 (Ref. 51243); 深さの範囲 0 - 1000 m (Ref. 54254), usually 0 - 200 m (Ref. 54254). Temperate; 75°N - 30°N, 77°W - 42°E

Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm 28.7, range 34 - ? cm
Max length : 60.0 cm FL オス/雌雄の選別がない; (Ref. 35388); common length : 30.0 cm FL オス/雌雄の選別がない; (Ref. 168); 最大公表体重: 3.4 kg (Ref. 9988); 最大記録サイズ: 17 年 (Ref. 207)
背面の脊椎 (合計): 8 - 14; 背鰭 (合計): 113; 肛門の骨 1; 臀鰭: 12 - 13; 脊つい: 31. This species has the following characters: no well developed corselet; interpelvic process small and single; anal fin spine conspicuous, joined to the fin by a membrane but clearly independent of it; anal fin origin opposite that of second dorsal fin; no swim bladder; first haemal spine anterior to first interneural process; 21-28 interneural bones under first dorsal fin; markings on back oblique to near vertical, with relatively little undulating; belly unmarked (Ref. 168).
Abundant in cold and temperate shelf areas, forms large schools near the surface. They overwinter in deeper waters but move closer to shore in spring when water temperatures range between 11° and 14°C. Mainly diurnal, it feeds on zooplankton and small fish. Eggs and larvae are pelagic (Ref. 6769). Batch spawner (Ref. 51846). The species is traded fresh, frozen, smoked and canned. Eaten fried, broiled and baked (Ref. 9988). Two stocks in north-east Atlantic: North Sea (east) and British Isles (west). North Sea stock decreased dramatically in the 1960's because of direct overfishing. Recruitment has been poor and unstable. After spawning, the adult feed very actively moving around in small shoals (Ref. 35388).
