Remarks: Robison and Buchanan (1988) reported redear sunfish as widely stocked in Arkansas in ponds and reservoirs, presumably in native waters. Menhinick (1991) listed this species as "regarded as native but possibly introduced" and "introduced" into the Catawba, Yadkin, Lumber, and Waccamaw drainages. Stauffer et al. (1995) differed with other authors (Lee et al. 1980 et seq. and Jenkins and Burkhead 1994) in reporting this species as native to the Potomac, Big Sandy, Kanawha, and Little Kanawha drainages, and Ohio basin. No records exist for New York (Whittier and Hartel 1997).
