* HUCs are not listed for states where the observation(s) cannot be approximated to a HUC (e.g. state centroids or Canadian provinces).
Means of Introduction: Probable aquarium release (Courtenay and Stauffer 1990).
Status: The Florida populations was first discovered in the mid-1970s (Shafland 1976); it was eradicated by personnel of the Florida Game and Fresh Water Fish Commission in 1975 (Courtenay and Stauffer 1990). The status of the Hillsborough Co. population is uncertain but it is probably no longer extant as no additinoal collections have been reported. The only published information on the Nevada introductions was an abbreviated account given by Robins et al. (1991b).
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.
