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: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
