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: Deepbody Anchovy

Taxonomy: available through www.itis.gov

Identification: No dorsal or anal spines.  Anal soft-rays: 27-34.  Moderately deep-bodied.  Snout pointed, about 1/2 to 3/4 eye diameter; maxilla moderate, tip rather blunt, not reaching to hind border of pre-operculum.  Anal fin origin a little before midpoint of dorsal fin base.  A bright silver stripe along flank, often as wide as eye, not fading on preservation.

Size: 13.3 cm SL

Native Range: From Point Conception, California, to southern Baja California (Mundy 2005).

Interactive maps: Point Distribution Maps

Ecology: Common in bays and inlets in California.  The species is a filter-feeder.

Means of Introduction: Intentionally stocked as a forage fish.

Status: Failed in Hawaii (Randall 1987; Mundy 2005).

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.
