The Gulf sturgeon (Acipenser oxyrinchus desotoi) is a subspecies of sturgeon that lives in the Gulf of Mexico and some rivers draining into it. The Gulf sturgeon was first recognized as a separate subspecies in 1955. The nominate subspecies is the Atlantic sturgeon, A. o. oxyrinchus. [5]
Timing and the unusual migratory behavior of sturgeon is a result of temporal water temperature changes. [7] Studies have also shown that amongst sturgeon in Gulf of Mexico and Suwannee River in Florida, fish gained 20% of their body weight while in Gulf of Mexico and lost 12% of their body weight during their time in the river.

Globally, sturgeon fisheries are of great value, primarily as a source for caviar, but also for flesh. [42] Several species of sturgeon are harvested for their roe which is processed into caviar—a delicacy, and the reason why caviar-producing sturgeons are among the most valuable and endangered of all wildlife resources.

Acipenser is a genus of sturgeons.With 17 living species (others are only known from fossil remains), it is the largest genus in the order Acipenseriformes.The genus is paraphyletic, containing all sturgeons that do not belong to Huso, Scaphirhynchus, or Pseudoscaphirhynchus, with many species more closely related to the other three genera than they are to other species of Acipenser.
Vulnerable (VU) species are considered to be facing a high risk of extinction in the wild. In September 2016, the International Union for Conservation of Nature (IUCN) listed 1245 vulnerable fish species. [1]

Gulf Sturgeon, Alabama Shad, and Skipjack Shad use the river for spawning activities; the U.S. Fish and Wildlife Service even collected 522 different sturgeon during a study conducted in October and November 2008; sizes ranging from 1 to 160 pounds. Scientists report sighting sturgeon as far upriver as Newton; they appear to prefer the ...
