在第一個鰓弓的下面部分上區別的特徵為灰白又幾乎無色的腹鰭與胸鰭與少數的鰓耙了。 (參考文獻 27547) 背部的相當高而鐮刀狀的; 腹鰭有腋窩的羽翼突起.(參考文獻 27547) 通常褐色的到深綠色的背面; 銀色的在下側與腹面上; 臀鰭、腹鰭與胸鰭灰白的; 尾部的與背鰭暗色的.(參考文獻 27547)
Found near river mouths and brackish lagoons (Ref. 5723). Adults make extensive migrations related to spawning (Ref. 27547). They feed on invertebrates and cottids (Ref. 27547). Apparently does not feed during its spawning runs (Ref. 27547). Some populations anadromous (Ref. 96339).
發現於靠近河口與半鹹淡水潟湖了。 (參考文獻 5723) 進行大規模的產卵的被有關的迴游。 (參考文獻 27547) 吃無脊椎動物與杜父魚科魚類。 (參考文獻 27547) 顯然地在它的產卵迴游的時候不進食。 (參考文獻 27547)
