簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 1; 背的軟條 (總數): 47-54; 臀棘 0; 臀鰭軟條: 37 - 41. Light brown above, silvery to white below (Ref. 6605).
背面淡褐色的, 銀色到腹面白色的.(參考文獻 6605)
Found on the continental shelf and slope to depths over 1,000 m (Ref. 27121). Juveniles (to about 64 cm) feed on small crustaceans and small deep-sea fishes such as lanternfishes, whereas larger individuals feed chiefly on small hakes and jack mackerel (Ref. 1371); cannibalism is common (Ref. 27121). Migrates southward in the spring and northward in autumn (Ref. 1371). Breeds throughout the year, peaks of reproductive activity in August and September (Ref. 36731). Marketed smoked, frozen, and fresh on ice; eaten steamed, fried and baked (Ref. 9988).
棲息於大陸棚及大陸坡到深度超過 1,000 公尺了。 (參考文獻 27121) 稚魚 (到大約 64 公分) 吃小型甲殼動物與小的深海魚例如燈籠魚, 然而較大的個體主要地以小的鱈魚與鰺科魚類鯖為食;(參考文獻 1371) 嗜食同類是普遍。 (參考文獻 27121) 在春天迴游南方與向北的秋天時.(參考文獻 1371) 全年繁殖, 在八月與九月的生殖活動的峰巔.(參考文獻 36731) 在市場上銷售煙燻, 在冰上的冷凍 , 與生鮮魚肉; 清蒸, 油炸而且燒烤。 (參考文獻 9988)
