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于河川源头而且时常维持领土; 它主要捕食昆虫也捕食小型甲壳动物与鱼。 海洋回游的形式去向下游形成群体, 而且在一个短停留在中之后，半咸淡的区域进入海洋在哪里它吃小鱼与大洋性甲壳动物。 卵生的.(参考文献 205) 卵被埋藏在没有防卫的巢之中。 (参考文献 205) 在市场上销售生鲜和冷冻; 吃火烤与烧烤的.(参考文献 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。
