Means of Introduction: The two fish were turned loose at the close of a fair exhibiting freshwater fishes from the eastern United States (Lampman 1946).
Status: Failed in Oregon.
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.
