The marine waters of New York State (excluding the Hudson River) are home to a large and diverse ichthyofauna that includes pelagics, migratory coastal fishes, resident species, anadromous and catadromous fishes, euryhaline-estuarine forms, and freshwater and deep-ocean strays. This diversity is attributable, in part, to the broad variety of habitats composing New York's marine waters. Also, although New York is located near the center of the Virginian biogeographic province, seasonal representatives of the Acadian and Carolinian provinces increase the breadth of its ichthyofauna. We record 338 fishes (114 families) reported from these waters, with annotations where warranted. Rare and unusual specimens are documented where possible with museum and literature citations.
