North America: Lower Great Lakes and Mississippi River basins from western Pennsylvania to White-Little Missouri River system in North Dakota, and south to Louisiana in USA; Gulf Slope from Mobile Bay drainage in Georgia and Alabama in USA to Mexico. Transplanted elsewhere in USA.

Length at first maturity / Tamaño / Peso / Age

Maturity: L_m 48.3, range 46 - 50.8 cm
Max length : 155 cm TL macho / no sexado; (Ref. 86798); peso máximo publicado: 55.8 kg (Ref. 40637); edad máxima reportada: 25 años (Ref. 120825)

Adults inhabit pools with logs and other debris in low-gradient to moderate-gradient, small to large rivers. Also found in lakes and impoundments. Young occur in rocky and sandy runs and riffles (Ref. 5723, 86798). Juveniles feed on aquatic insect immature in riffle areas (Ref. 10294). Older individuals consume crayfish, clams and fishes (Ref. 93252).
