Length at first maturity / Size / Weight / Age
Maturity: Lm 32.0  range ? - ? cm
Max length : 76.0 cm TL male/unsexed; (Ref. 5723); common length : 35.8 cm TL male/unsexed; (Ref. 12193); max. published weight: 4.0 kg (Ref. 4699); max. reported age: 18 years (Ref. 72496)
North America: St. Lawrence-Great Lakes, Hudson Bay, and Mississippi River basins from Quebec to Alberta in Canada, and south to northern Alabama and Louisiana in the USA. Introduced into Atlantic, Gulf and southern Mississippi River drainages.
Inhabit sand and gravel runs, sandy and muddy pools and backwaters, of small to large rivers; less often in lakes and impoundments (Ref. 10294, 11003). Larvae feed on cladocera, copepods, and midge larvae, while juveniles consume fishes (Ref. 10294). Spawn between March and June (Ref. 10999) in pairs or small aggregations (Ref. 11003).
