Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 0; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 16 - 19. Snout long, pointed, about 3/4 eye diameter; maxilla moderate, tip not sharply pointed, not or only just reaching to hind border of pre-operculum; gill cover canals of panamensis-type. Anal fin short, its origin below or behind midpoint of dorsal fin base. A broad silver stripe along flank, about 3/4 eye diameter.
A schooling species found in coastal waters, but also entering brackish water. More data needed (Ref. 189). Found in markets (Ref. 37032). Largely utilized as bait for commercial fishery, oil, flour, and also canned fish (Ref. 103984).
