Adults return to natal streams from the sea to spawn (Ref. 27547). Fry may migrate to the sea after only 3 months in fresh water, some may stay for as long as 3 years, but generally most stay a year in the stream before migrating (Ref. 27547). Some individuals remain close inshore throughout their lives, but some make extensive migrations (Ref. 27547, 44894). Also found in lakes (Ref. 1998). Possibly up to 375 m depth (Ref. 6793). Epipelagic (Ref. 58426). Food in streams is mainly terrestrial insects and small crustaceans; in the sea, major food items include fishes, crustaceans, and other invertebrates (Ref. 27547). Young are preyed upon by fishes and birds (such as mergansers and kingfishers); adults are prey of large mammals and large birds (Ref. 1998). Highly regarded game fish (Ref. 27547). Flesh is usually red, but some are white; the red meat commands a higher price (Ref. 27547). Marketed fresh, smoked, frozen, and canned. Eaten steamed, fried, broiled, boiled, microwaved, and baked (Ref. 9988). Viscera said to contain high vitamin A content and used successfully as food for hatchery fish (Ref. 28971, 28977).
成鱼回到出生的溪流距离海洋产卵.(参考文献 27547) 鱼苗可能回游到海洋在只有 3个月之后在淡水中,一些可能停留长达 3 年, 但是在移动之前通常最在水流中停留一年.(参考文献 27547) 一些个体在他们的生命各处保持近岸,但是一些作广泛的回游。 (参考文献 27547,44894) 也发现于湖。 (参考文献 1998) 可能地向上到 375 公尺深。 (参考文献 6793) 在溪流的食物是主要陆栖的昆虫与小型甲壳动物; 在海洋中,主要的食物组成包括鱼,甲壳动物与其他的无脊椎动物。 (参考文獻 27547) 幼魚被魚與鳥 (例如秋沙鴨與魚狗) 捕食; 成魚是大哺乳動物與大的鳥捕食.(參考文獻 1998) 獲高度評價遊釣魚類。 (參考文獻 27547) 肉通常是紅色,但是一些是白色的; 紅色的肉具有較高的價格。 (參考文獻 27547) 在市場上銷售生鮮、煙燻﹐冷凍的﹐與罐裝的。 清蒸,油炸,火烤, 煮沸, 微波了, 而且燒烤了.(參考文獻 9988) 內臟說包含高含量的維他命 A 與成功地當作食物對於孵卵所魚是使用過的.(參考文獻 28971,28977) 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。
