Disclaimer:

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.

Common name: Sargo

Taxonomy: available through www.itis.gov

Identification: Miller and Lea (1972); Thomson et al. (1979); Eschmeyer et al. (1983). Also appears as A. davidsoni.

Size: 58 cm.

Native Range: Tropical, marine. The sargo is native to the Pacific Ocean from Santa Cruz, California, to southern Baja California (Eschmeyer et al. 1983).

Interactive maps: Point Distribution Maps

Means of Introduction: A total of 65 fish were stocked in the Salton Sea in 1951 by the California Department of Fish and Game (Walker et al. 1961). The means and reason for introduction to New Mexico are unknown.

Status: Extirpated in Californa and New Mexico.

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 feeds on crustaceans, mollusks, and bryozoans (Eschmeyer et al. 1983). The population in the Salton Sea was at times very large and represented a major fishery in the lake (Walker et al. 1961; Shapovalov et al. 1981).
