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.

Means of Introduction: Twelve fish entered the bait tanks through the circulation system from San Diego Bay and were knowingly introduced in 1948 as a result of stock-contamination (Dill and Cordone 1997).

Status: Extirpated in California.

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: A second species of Peprilus (P. ovatus) has previously been reported as introduced to California (Hubbs et al. 1979), likely in the Salton Sea (Dill and Cordone 1997); however, this species was not included in the list of fishes introduced to the Salton Sea published by Walker et al. (1961). Dill and Cordone (1997) provide evidence that the record of P. ovatus likely stems from a misidentification of P. simillimus found sometime in 1961-1963 and was assumed by Hubbs et al. (1979) to have originated from Mexico.
