The fluviatile form generally inhabits headwaters and often maintains a territory; it feeds mainly on insects but also on small crustaceans and fishes. The sea-run form goes downstream forming schools, and after a short stay in the brackish zone enters the sea where it feeds on small fishes and pelagic crustaceans. Oviparous (Ref. 205). Eggs are buried in unguarded nests (Ref. 205). Marketed fresh and frozen; eaten broiled and baked (Ref. 9988).
生活在河中的形式通常居住於河川源頭而且時常維持領土; 它主要捕食昆蟲也捕食小型甲殼動物與魚。 海洋迴游的形式去向下游形成群體, 而且在一個短停留在中之後，半鹹淡的區域進入海洋在那裡它吃小魚與大洋性甲殼動物。 卵生的.(參考文獻 205) 卵被埋藏在沒有防衛的巢之中。 (參考文獻 205) 在市場上銷售生鮮和冷凍; 吃火烤與燒烤的.(參考文獻 9988)
Distinct pairing (Ref. 205). Reproductive strategy: synchronous ovarian organization, determinate fecundity (Ref. 51846).西北太平洋: 鄂霍次克海與日本海; 日本北部與韓國半島東部。
