Inhabits ocean and coastal streams (Ref. 86798). Migrating fry form schools in estuaries, remain close to shore for a few months and finally disperse to enter the sea (Ref. 1998). Epipelagic (Ref. 58426). Juveniles and adults feed mainly on copepods, tunicates and euphausiids but also on pteropods, squid and small fishes (Ref. 1998). Adults cease feeding in freshwater (Ref. 1998). Males and females die after spawning. The catch is mostly canned but also sold fresh, dried-salted, smoked, and frozen. Eaten steamed, fried, broiled, boiled, microwaved, and baked (Ref. 9988). Utilized for caviar.
栖息于海洋与海岸的溪流。 回游鱼苗在河口形成鱼群, 保持接近海岸数个月而且最后分散进入海洋.(参考文献 1998) 稚鱼与成鱼主要捕食桡脚类的动物, 被囊类,而且磷虾也捕食翼足目的软件动物,乌贼与小鱼。 (参考文献 1998) 成鱼停止觅食于淡水。 (参考文献 1998) 雄性与雌性在产卵之后死亡。 捕捉大部份被装于罐头也卖了生鲜地, 被烟熏的乾燥盐腌 , 与冷冻。 清蒸,油炸,火烤, 煮沸, 微波了, 而且烧烤了.(参考文献 9988) 用来做鱼子酱了。 这种的阿拉斯加州鲑鱼渔场已经被检定藉由海洋的总管职务会议 (http:// www.msc.org/) 当管理良好且族群能维持。
