The American pickerels are two subspecies of Esox americanus, a species of freshwater fish in the pike family (family Esocidae) of order Esociformes: the redfin pickerel, E. americanus americanus Gmelin, 1789, and the grass pickerel, E. americanus vermiculatus Lesueur, 1846. Both subspecies are native to North America. They are not to be confused with their aggressive counterpart the Northern pike. The redfin pickerel's range extends from the Saint Lawrence drainage in Quebec down to the Gulf Coast, from Mississippi to Florida, while the grass pickerel's range is further west, extending from the Great Lakes Basin, from Ontario to Michigan, down to the western Gulf Coast, from eastern Texas to Mississippi. Order: Esociformes, Family: Esocidae.
