生態學
; 淡水 居於水底的. 溫帶; ? - 33°C (Ref. 12741); 47°N - 26°N, 108°W - 80°W (Ref. 86798)
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.
北美洲: 來自西方的賓州到的五大湖下游與密西西比河流域在達科塔北方部的白色-小的密蘇里河流域, 而且南至在美國的路易斯安那; 從在喬治亞州與阿拉巴馬州的摩比灣流域到墨西哥的海灣斜坡。 移植了在美國的其他地方。
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 48.3, range 46 - 50.8 cm
Max length : 155 cm TL 雄魚/尚未辨別雌雄; (Ref. 86798); 最大體重: 55.8 kg (Ref. 40637); 最大年齡: 25 年 (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).
棲息於有圓木與其他殘礫的水池在坡度緩之到中等的-坡度，小型到大型河川。 也發現於湖與圈圍水域。 幼魚出現在岩石的與多沙的支流與急流.(參考文獻 5723) 稚魚吃水生的昆蟲不成熟的在急流區域中.(參考文獻 10294)

50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00412 - 0.00733), b=3.13 (3.04 - 3.22), in cm total length, based on LWR estimates for this species (Ref.
93245).
營養階層 (Ref.
69278): 3.8 ±0.3 se; based on diet studies.
Generation time: 7.8 (6.9 - 9.5) years. Estimated as median ln(3)/K based on 24
growth studies.
回復力 (Ref.
