Nonindigenous Occurrences: Stocked in the Cape Fear (Deep system), and Tennessee drainages, and in nonnative areas of the Neuse and Tar drainages in North Carolina (Menhinick 1991). Also stocked in the upper and lower James, and middle New, and upper Roanoke drainages of Virginia (Jenkins and Burkhead 1994).
Means of Introduction: Intentional stocking for sportfishing. The lower James River was stocked in 1877 with fish from "Stony Creek". There are many "Stony Creeks" in Virginia, but this probably refers to one in the Chowan drainage. One individual was caught six years later. No others have been recorded. The upper James was also stocked in 1877 with fish from the Roanoke. This stocking also failed. In 1879, two adults from the Roanoke River were stocked in the New River at Radford, but they too failed to reproduce (Jenkins and Burkhead 1994).
Status: Extirpated in the upper and lower James and middle New drainages in Virginia. Stockings in North Carolina did not establish populations (McBride et al. 1982; Jenkins and Burkhead 1994).
Impact of Introduction: Unknown.
Remarks: Roanoke bass are nearly extirpated in the upper Roanoke drainage due to competition from the introduced rock bass A. rupestris (Lee et al. 1980 et seq.; Jenkins and Burkhead 1994). Both North Carolina and Virginia list Roanoke bass as a species of special concern (Jenkins and Burkhead 1994).
