Means of Introduction: This fish was likely stocked in conjunction with fish rescue and transfer efforts from the Mississippi River in the 1930s (Becker 1983).
Status: Reported from Wisconsin.
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.
