Means of Introduction: Probable bait bucket releases, multiple introductions to a drainage seem possible (Jenkins and Burkhead (1994). According to Jenkins and Burkhead (1994), the species was first recorded in the South Fork of the Shenandoah in 1956, Straight Creek in 1975, the Rapidan in 1951, the upper Rappahannock in 1974, the Pee Dee in North Carolina in 1970, the Pee Dee in Virginia in 1983-1984, and the Holston in 1966 (possibly as early as 1955). The population in the Rapidan likely came from the nearby James River. Jenkins and Burkhead noted that the availability of this species to bait seiners and its spectacular coloration increase the probability of this fish being moved about in bait buckets.
Status: Reported from, possibly established in, the Pee Dee River drainage of North Carolina. Established in Virginia in all drainages mentioned except, possibly, the Holston.
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.
