生物學特性     字彙 (例如 epibenthic)

Abundant on sandy grounds and strays into shallower waters. A voracious predator with cannibalistic habits. Individuals over 40 cm TL prey on fishes such as gadoids and herring, while smaller ones feed on crustaceans, i.e. euphausiids and pandalids; food also includes gaspereau, myctophids, smelt, silversides, mackerel, sand lance, butterfish, snakeblennies, longhorn sculpins and squids (Ref. 5951). The smallest specimen feeds mostly on crustaceans (Ref. 58452). Exhibits seasonal onshore-offshore migration (Ref. 9988). Spawning takes place from June-July in the mid-Atlantic region; July-August in the Gulf of Maine and to the north of Georges Bank, and August-September on the Scotian Shelf (Ref. 58452). Marketed fresh, smoked and frozen; fresh fish are exported to European markets; eaten fried, broiled, microwaved and baked (Ref. 9988).

豐富的在沙的地面上而且迷途進入較水淺的水域內。 一個狼吞虎嚥的掠食者有同類相食的習慣。 超過 40 公分TL 的個體捕食魚例如雪科與鯡魚,然而較小的一些吃甲殼動物, 也就是磷蝦與長額蝦; 食物也包括 gaspereau ,燈籠魚科魚類,胡瓜魚,銀漢魚,鯖,沙子鎗矛,溜滑的魚, snakeblennies ,長角牛杜父魚科的河魚與烏賊。 (參考文獻 5951) 顯示季節性的向陸及離陸的遷移。 在市場上銷售生鮮、煙燻與冷凍; 新鮮的魚被輸出到歐洲的市場; 油炸後食用, 火烤., 微波.而且燒烤.。 (參考文獻 9988)

Spawning appears to be strongly influenced by water temperature, and annual variations occur both in the peak and the range of the spawning period, which may influence considerably the growth of juveniles. 西北大西洋: 來自鈴島峽道到巴哈馬的加拿大與美國的海岸; 最常見的從紐芬蘭南部到南卡羅萊那州。
