† Populations may not be currently present.
Means of Introduction: Introduction of Snail Bullheads may have resulted from stock contamination of black bullheads (Ameiurus melas) that were stocked in Belews Lake, North Carolina, on the upper Dan River (Burkhead et al. 1980). Unknown means in Georgia.
Status: Established in Georgia, North Carolina, 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.
