生物学特性     字汇 (例如 epibenthic)

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.

出现于海岸的栖息地夏天时与冬天.(参考文献 1371) 在碧佛海洋中,它也可能被发现于半咸淡的泻湖与在河口中的几乎淡水中.(参考文献 1371) 虽然伴随着冰 (白海) 的发生, 它是出现在不会冰冻的近岸水域 (阿拉斯加州).(参考文献 1371) 向陆及离陆的运动被伴随着产卵与冰的运动.(参考文献 27547) 大部份捕食浅海底栖糠虾,也吃端脚类动物,桡脚类的动物与鱼。 (参考文献 1371) 也用中层水域拖网捕获。 (参考文献 1371) 用来作鱼粉与油的来源了。 (参考文献 1371) 广盐性与广温性的。

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。
