The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

† 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.

Remarks: This species is listed as 'vulnerable' on the IUCN Red List due to chronic overfishing and the reduction/termination of water flow in their primary spawning habitat (Colorado River).
