Shortnose Sturgeon
Acipenser brevirostrum LeSueur, 1818
Ray-finned Fishes

New York State Distribution [-]
Shortnose sturgeon are restricted to the Hudson River between New York City and the Troy dam. Historically, this species occurred north to Cohoes Falls at the mouth of the Mohawk River (Carlson 1998).

Global Distribution [-]
The shortnose sturgeon is found on the Atlantic Coast of North America where its range extends from the Saint John River, New Brunswick to the St. Johns River, Florida. The federal recovery plan (NMFS 1998) for the species identifies 19 distinct population segments, each defined as a river/estuarine system in which shortnose sturgeons have been captured in the generation time of the species (30 years). The population segments recognized by the recovery plan are: Saint John, Penobscot, Kennebec System (Sheepscot, Kennebec, and Androscoggin Rivers), Merrimack, Connecticut, Hudson, Delaware, Chesapeake (Chesapeake Bay and Potomac River), Cape Fear, Winyah Bay (Waccamaw, Pee Dee, and Black Rivers), Santee (Santee River and Lake Marion), Cooper, ACE Basin (Ashepoo, Combahee, and Edisto Rivers), Savannah, Ogeechee, Altamaha, Satilla, St. Marys, and St. Johns. As of the late 1980s, the largest concentrations were in the Saint John River (New Brunswick); Kennebec River (Maine); Hudson River (New York); Delaware River (New Jersey); Winyah Bay, Pee Dee River, and Lake Marion (South Carolina); and the Altamaha River (Georgia). The species recently reappeared in the lower Susquehanna River drainage of the upper Chesapeake Bay basin (possibly from the Delaware River via the Chesapeake and Delaware Canal) (see Burkhead and Jenkins 1991). Populations may be semidisjunct (Carter 1989). See Stone et al. (1994) for information on distribution and relative abundance in mid-Atlantic estuaries.
