Description

The rough silverside is a small schooling fish of the silverside family (Atherinopsidae) from the western Atlantic off the east coast of North America. The species grows to about 13 cm and has a slender, translucent, silvery body with a bright silver lateral stripe; the scales feel somewhat rough, to which the name refers. It occurs along shore and in bays and inlets, where it swims in schools. As an omnivore it feeds on zooplankton and small invertebrates. As an abundant prey fish it is important to larger predatory fishes and seabirds. The species is harmless to humans.
