Description

The jacksmelt is a silverside of the family Atherinopsidae from the eastern Pacific off the west coast of North America. The species grows to about 45 cm and has a slender, silvery body with a bright silver lateral stripe and two separate dorsal fins. It lives in schools in shallow coastal waters and bays and feeds on plankton and small invertebrates. It is a demersal spawner: the eggs are attached to one another and to the substrate by adhesive filaments, and the larvae live planktonically near the surface. The species is taken by commercial and recreational fisheries.
