Description

The inland silverside is a slender, translucent silvery fish of the family Atherinopsidae (New World silversides) reaching about 15 cm. The streamlined body bears a conspicuous shiny silvery lengthwise band along the flank and has an upturned mouth. The species is extremely salt-tolerant and lives in estuaries, lagoons, coastal water and fresh rivers and lakes of eastern and southern North America. In large schools at the surface it hunts zooplankton, insect larvae and small crustaceans. In the warm months the threaded eggs attach to water plants. Through its great numbers it is an indispensable prey fish for countless larger fish and waterbirds and is used as bait.
