Nonindigenous Occurrences: This species was stocked in a pond west of Salt Lake City, Utah, in 1979, in a waterbody where it was not originally found (Baugh 1980; Sigler and Sigler 1987).

Means of Introduction: Intentionally stocked for conservation purposes to create another population of a rare species.

Status: Status of stockings conducted in the late 1980s has not been evaluated (Sigler and Sigler 1996).

Impact of Introduction: Unknown.
