† Populations may not be currently present.
Means of Introduction: Some records may represent regular immigrants from central California (Swift et al. 1993). Some records may be the result of bait bucket releases. The species was reportedly sold as bait in the lower Colorado River (Miller 1952). Kimsey and Fisk (1960) suggested that it was one of several species in California widely transported as bait. They reported that it was collected in 1954 from Ramer Lake, Imperial County, about 320 road miles south of its regular range.
Status: Established in parts of southern California (Swift et al. 1993).
Impact of Introduction: Unknown. Possibly in reference to introduced populations, Moyle (1976a) stated that the species is largely regarded as a nuisance by fisheries managers.
