Nonindigenous Occurrences: This species was introduced into Walter E. Long Reservoir and Victor Braunig Reservoir in Travis and Bexar counties, Texas (Lasswell et al. 1979; Howells 1991; Howells and Garrett 1992; Waldrip 1993). Seatrout also was introduced into New Mexico but it has since been extirpated (Sublette et al. 1990).

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: Unknown.

Remarks: The Texas stockings totaled 78,092 fish (Howells and Garrett 1992). Sublette et al. (1990) included this species in their list of "fishes introduced into New Mexico, now considered extirpated." However, they provided no additional information.
