The Gulf Sturgeon (Acipenser oxyrinchus ssp. desotoi) as the name implies lives in the estuaries of the Gulf of Mexico but migrates up coastal rivers to spawn (anadromous). It is found in rivers from spring until fall and in the Gulf during the winter. It feeds heavily while in the Gulf, but adults eat very little (or not at all) while in the rivers. The species declined dramatically after the late 1800s. It fell victim to overharvest for its meat and roe, dam construction, and dredging activities. The largest population is currently in the Suwannee River in Florida.
