Lives in clear, flowing streams with abundant cover (Ref. 5259, 44894). Prefers streams with gravel bottoms and abundant snags. Also occurs in lakes and reservoirs (Ref. 5259). Tolerant of slightly brackish conditions (10 p.p.t.) in the tidal reaches of rivers, and a temperature range of 5°-25°C. Home-ranging; remaining within about a 20-30 meters stretch of water throughout the life span (Ref. 44894). Feeds on insects, crustaceans and small fishes (Ref. 5259) ; also on mollusks (Ref. 2156). The spawning season runs from November to January. A popular angling species in the south, but large fish are rare. Highly susceptible to overfishing, due to its home-ranging behavior and low fecundity (Ref. 44894). Flesh is oily and not very good eating.
生活在清澈又流动的溪流有丰富的表面.(参考文献 5259,44894) 偏爱溪流有砾石的底部与丰富的断枝。 也生活于湖与水库中。 (参考文献 5259) 宽容的些微半咸淡环境 (10 p.p.t.) 在河川中潮汐能达到的范围 , 与 5 的温差中 °-25 ° C. 以出生地为范围分布; 保持在生活各处大约在水的 20-30 公尺伸展之内跨越。 (参考文献 44894) 吃昆虫，甲壳动物与小鱼 ;(参考文献 5259) 也在软件动物上.(参考文献 2156) 产卵季节从十一月到一月。 在南方中的一個受歡迎的釣魚種, 但是大的魚是稀有的。 高度地易受捕撈過度, 由於它的以出生地為範圍分佈行為與低的孕卵數.(參考文獻 44894) 肉是多油的而不是非常好的吃。
