Means of Introduction: First observed in Maine in 1982, probably bait bucket release of illegally imported baitfish (Kircheis 1994).
Status: Established in Maine. The species was first observed in the Kennebec River drainage in 1982; first confirmed reproduction also was 1982 (Kircheis 1994).
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.
