† Populations may not be currently present.
Means of Introduction: Intentionally stocked by the Texas Parks and Wildlife Department from 1984 through 1986 as a sport fish.
Status: As of 1990, only a few hybrids still survived in Calaveras Reservoir. It was predicted that the populations would soon die out (Howells 1991a, 1991c; Howells and Garrett 1992).
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.
