Means of Introduction: Authorized stockings took place in the 1930s and 1940s. The stocking in Idaho took place in 1939 (Linder 1963). The stocking in Maine took place in 1938 (Everhart 1950). The Michigan stocking occurred in 1945 (Emery 1985).
Status: Stocking attempts failed to generate reproducing populations.
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.
