Means of Introduction: Unknown; possible bait bucket introductions. According to Bart et al. (1994), there are two plausible explanations for this species' present distribution within the Ocmulgee River system. The original entry may have been below Lake Jackson after 1971, with subsequent dispersal to other areas (and an independent introduction into Tussahaw Creek above Lake Jackson). Or, the entry could have occurred above Lake Jackson after the late 1970s, with subsequent dispersal to areas below the lake. The Clinch River, Virginia records probably represent one or more introductions form the Big Sandy (Jenkins and Burkhead 1994).
Status: Reported from Georgia and Virginia.
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.
