New World Silverside

Family: Atherinopsidae

New world silversides are small fish with upturned mouths, two, widely separated dorsal fins, and a strong, mirror-like silver stripe on both sides of the body. As the name implies, they are found throughout North and South America and many species are marine or estuarine. Although four species are found in New York's inland waters, only one species is strictly freshwater. The brook silverside occurs in the watersheds of the Saint Lawrence drainage, the Allegheny and recently has repopulated the Hudson River drainage. It is typical of vegetated areas in streams and lakes. The other three species are found in the lower Hudson River and coastal streams on Long Island. They are not considered to be inland species within this map series.

It is native in seven Great Lakes watersheds and in the Allegheny; it is nonnative in the Champlain, Mohawk, Upper and Lower Hudson watersheds. Recently its range has expanded and it has become more abundant.
