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.
棲息於海洋與海岸的溪流。 迴游魚苗在河口形成魚群, 保持接近海岸數個月而且最後分散進入海洋.(參考文獻 1998) 表層帶.(參考文獻 58426) 稚魚與成魚主要捕食橈腳類的動物, 被囊類,而且磷蝦也捕食翼足目的軟體動物,烏賊與小魚。 (參考文獻 1998) 成魚停止覓食於淡水。 (參考文獻 1998) 雄性與雌性在產卵之後死亡。 捕捉大部份被裝於罐頭也賣.生鮮地, 乾燥鹽醃,煙燻., 與冷凍。 清蒸,油炸,火烤, 煮沸, 微波., 而且燒烤..(參考文獻 9988) 用來做魚子醬.。 這種的阿拉斯加州鮭魚漁場已經被檢定藉由海洋的總管職務會議 (http://www.msc.org/) 當管理良好且族群能維持。
