北美洲: 從魁北克到加拿大亞伯達省的聖勞倫斯河-五大湖區，哈得遜灣與密西西比河流域, 而且南至在美國的阿拉巴馬州北部與路易斯安那。 引入大西洋，灣與南方的密西西比河流域中了。
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 32.0 range ? - ? cm
Max length : 76.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 86798); common length : 35.8 cm TL 雄鱼/尚未辨别雌雄; (Ref. 12193); 最大体重: 4.0 kg (Ref. 4699); 最大年龄: 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).
栖息于沙与碎石小支流，沙泥深潭与滞水区, 小型到大型河川; 较不常见于湖与圈围水域。 在三月与六月 (参考文献 10999) 之间产卵成对或小群鱼群.(参考文献 11003)
