Means of Introduction: Intentionally stocked for sportfishing by the Delaware Division of Fish and Wildlife.
Status: Maintained by stocking.
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.
