Introduced into the Mohawk River in New York (Mills et al. 1997). Specimens have been taken at Lock 7 near Schenectady and at Lock 9 at Rotterdam Junction (Smith 1985; Mills et al. 1997). Smith (1985) mapped another location on the Mohawk near Little Falls, where it is presumably also introduced. The eastern range expansion is relatively recent, Lee et al. (1980 et seq.) reported it only as far east as Oneida Lake.

† Populations may not be currently present.
Means of Introduction: Canal connection. Probably gained access from Lake Ontario systems in western New York to the Mohawk River via the Erie Canal (Smith 1985; Mills et al. 1997).
Status: Reported in New York.
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.
