Occurs in coastal habitats during summer and winter (Ref. 1371). Cryopelagic or epontic, from surface down to 1383 m (Ref. 58426). In the Beaufort Sea, it may also be found in brackish lagoons and in almost fresh water in river mouths (Ref. 1371). Although associated with the occurrence of ice (White Sea), it is present in ice-free near-shore waters (Alaska) (Ref. 1371). Onshore-offshore movements are associated with spawning and movements of the ice (Ref. 27547). Feeds mostly on epibenthic mysids, also amphipods, copepods and fishes (Ref. 1371). Also caught with mid-water trawls (Ref. 1371). Utilized as fishmeal and source of oil (Ref. 1371). Euryhaline and eurythermic.
出現於海岸的棲息地夏天時與冬天.(參考文獻 1371) 寒帶大洋性的或 epontic.(參考文獻 58426) 在碧佛海洋中，它也可能被發現於半鹹淡的潟湖與在河口中的幾乎淡水中.(參考文獻 1371) 雖然伴隨著冰 (白海) 的發生, 它是出現在不會冰凍的近岸水域 (阿拉斯加州).(參考文獻 1371) 向陸及離陸的運動被伴隨著產卵與冰的運動.(參考文獻 27547) 大部份捕食淺海底棲糠蝦，也吃端腳類動物，橈腳類的動物與魚。 (參考文獻 1371) 也用中層水域拖網捕獲。 (參考文獻 1371) 用來作魚粉與油的來源.。 (參考文獻 1371) 廣鹽性與廣溫性的。

Oviparous, sexes are separate (Ref. 101194). Fish move close inshore, often in large numbers to spawn (Ref. 27547).在北極圈的極地附近。 北大西洋: 進入 Miramichi 河，加拿大的新布蘭斯維克之內的白海，冰島與格陵蘭南部。 北太平洋: 白令海到岬 Olyutorski ， Pribilof 島與布里斯多海灣。
