Range Description

Gulf Sturgeon were first described as a subspecies to A. oxyrinchus (Atlantic sturgeon) in 1955. They occur in most major river systems from the Mississippi River to the Suwannee River in Florida and in marine waters of the Central and Eastern Gulf of Mexico south to Florida Bay. Though the species was previously listed as also occurring in Mexico, a review of the literature fails to support that contention. A single "sturgeon" was reported seen (but not captured) in the Rio Grande River which separates Texas and Mexico. The Gulf sturgeons current area of occupancy is spread over 2,500+ river km and 1,500+ km of coastline. However, construction of dams, sills and other water control structures throughout the 20th century severely restricted inland migrations of Gulf sturgeon in many waterways from St. Andrew Bay, FL to the Bogue Chitto River, LA.
