Kort beskrivning
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 0; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 27 - 34. Moderately deep. Snout pointed, about 1/2 to 3/4 eye diameter; maxilla moderate, tip rather blunt, not reaching to hind border of pre-operculum; pseudobranch short, covered by skin; gill cover canals of panamensis-type. 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.
Body shape (shape guide): elongated; Cross section: oval.
A schooling species most commonly found in bays and inlets (the fourth most abundant fish taken by various gear in Newport Bay, California; its eggs are the most abundant of 7 species sampled, especially in May). The ovarian eggs are spherical. Eggs and larvae are planktonic (Ref. 35602). Feeds on plankton (Ref. 8593). Basically filter-feeders, but at times have been observed feeding by selection (Ref. 4930). Normally used as bait (Ref. 9298).
