† Populations may not be currently present.
Means of Introduction: Intentionally introduced as a sport fish in 1951 and 1956 from fishes obtained from San Felipe, Mexico (Walker et al. 1961).
Status: The introduction failed to produce a viable population and the species is extirpated in the Salton Sea.
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.
