† Populations may not be currently present.
* 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: It was stocked by the Texas Parks and Wildlife Department in the 1970s and 1980s as a sportfish (Lasswell et al. 1979; Howells 1991; Howells and Garrett 1992).
Status: Because there has been no reproduction, it was predicted that the inland population in Texas would die out due to natural mortality and fishing (Howells and Garrett 1992). This species is extirpated in New Mexico (Sublette et al. 1990).
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.
