Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 32.0 range ? - ? cm
Max length : 76.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 86798); common length : 35.8 cm TL 雄魚/尚未辨別雌雄; (Ref. 12193); 最大體重: 4.0 kg (Ref. 4699); 最大年齡: 18 年 (Ref. 72496)
Inhabits sand and gravel runs, sandy and muddy pools and backwaters of small to large rivers (Ref. 86798). Less frequent in lake and impoundments (Ref. 86798). Larvae feed on cladocerans, copepods, and midge larvae, while juveniles consume fishes (Ref. 10294). Spawn between March and June (Ref. 10999) in pairs or small aggregations (Ref. 11003).
棲息於沙與碎石小支流，沙泥深潭與滯水區, 小型到大型河川; 較不常見於湖與圈圍水域。 (參考文獻 10294,11003) 仔魚吃 cladocera ，橈腳類的動物與蚊仔魚, 而稚魚消費魚.(參考文獻 10294) 在三月與六月 (參考文獻 10999) 之間產卵成對或小群魚群.(參考文獻 11003)
