Common name: Deepbody Anchovy
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).
In 1932, 6,000 individuals were transported via a tuna clipper from California to Kane'ohe Bay, Oahu, Hawaii (Macioleck 1984, Randall 1987). The species failed to establish in Hawaii (Mundy 2005).

† Populations may not be currently present.
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.
