Congress has recognized that endangered and threatened species of wildlife and plants “are of aesthetic, ecological, educational, historical, recreational, and scientific value to the Nation and its people.” When it passed the Endangered Species Act (ESA) in 1973 Congress promoted the recovery of  threatened and endangered species, and the conservation of the critical habitat on which they depend. All sea turtles species in the Gulf are at risk of possible extinction, but none are … NOAA Fisheries and the U.S. FWS co-manage Gulf sturgeon. The decline was exacerbated by habitat loss associated with the construction of water control structures, such as dams and sills (submerged ridge or vertical wall of relatively shallow depth separating two bodies of water), mostly after 1950. Gulf sturgeon are among nine sturgeon species and subspecies native to North America and among at least five listed as endangered or threatened. The Gulf of Maine DPS is one of eight NMFS Species in the Spotlight, which is comprised of species listed under the ESA for which immediate, targeted efforts are vital for stabilizing their populations and preventing their extinction. This sill, located on the Bogue Chitto river near Bush, LA, is a permanent concrete structure that impedes Gulf sturgeon attempting to migrate upstream to spawn.

They are big – reaching 14 feet in length and 800 pounds (though the Gulf sturgeon does not reach the large size of their cousin the Atlantic sturgeon). A species is considered endangered if it is in danger of extinction throughout all or a significant portion of its range. The species, which inhabits coastal rivers, bays, and estuaries from Louisiana to Florida and the Gulf of Mexico, was listed as threatened under the Endangered Species Act in 1991. “This widespread evidence of decline alerts us to the fact that despite protective fishing regulations, sturgeon are still in trouble due to historic fishing, current illegal fishing and habitat degradation,” says Dr Kent Carpenter, IUCN Global Marine Species Assessment Director . Although scientists have classified approximately 1.7 million organisms, they recognize that the overwhelming majority have not yet been catalogued, as it is estimated that between 10 and 50 million species may inhabit our planet worldwide (Why Save Endangered Species? These protections were needed … Following delisting, a long-term fishery management objective is to establish self-sustaining populations that could withstand directed fishing pressure within discrete management units. The decline started back in the 1800's. We are committed to the protection and recovery of the Gulf sturgeon by implementing various conservation, regulatory, and enforcement measures. Gulf sturgeon spawn in rivers in the spring and fall and spend the summer months in the riverine habitat between the upstream spawning areas (where they lay their eggs) and the estuary (area where a river meets the sea). The Gulf sturgeon, Acipenser oxyrinchus desotoi, is a large, primitive fish that has bony plates, or "scutes," rather than scales and a hard, extended snout. Our work includes: We conduct various research activities on the biology, behavior, and ecology of the Gulf sturgeon. In addition to the seven spawning riverine populations, Gulf sturgeon are also known to inhabit the Mississippi, Mobile, and Ochlocknee rivers. Gulf sturgeon are anadromous fish, spending winter months in the warm waters of the Gulf of Mexico where they grow and increase their condition by feeding on tiny, bottom-dwelling invertebrates. Research should particularly focus on movements made from the nearshore estuarine environment to the marine environment and back for adults and juveniles and within-estuary movements for young-of-year sturgeon. There is an ongoing multiyear survey and monitoring project to standardize data collection and collect critical data to assess the status of the Gulf sturgeon. Subadults and adults do not feed when they are in the river. In 1991, Gulf sturgeon were listed as threatened under the Endangered Species Act after their population was greatly reduced or eliminated throughout much of their range because of overfishing, dam construction, and habitat degradation. The dredging of river channels is a practice that can destroy or suffocate sturgeon eggs located on objects in the river.

Fish and Wildlife Service publication, Why Save Endangered Species? However, the majority of individuals show a strong fidelity to specific rivers, requiring research and recovery efforts that focus on individual rivers. Because Gulf sturgeon spawn in the rivers in which they were born, a breeding population can be defined as the individuals natal to a particular river, and abundance is calculated as the number of individuals within that breeding population. This is one of the most promising means of inexpensively estimating the abundance of sturgeon in a river at a given time. Sturgeon Decal. The populations in Canada are not protected. Partially funded by the USFWS Partners for Fish and Wildlife Program, the Tuolumne River Trust worked for 10 years to acquire the Dos Rios Ranch property in Modesto, California. Tracks the implementation of recovery actions from Endangered Species Act (ESA) recovery plans. Tools exist to help communities identify threatened and endangered species and critical habitat within their jurisdictions. We conduct various research activities on the biology, behavior, and ecology of this species. The text and links below explore the stories of just a few of these species and their ties to the floodplain. Beluga sturgeon populations have been decimated in part due to unrelenting exploitation for black caviar – the sturgeon’s unfertilized eggs – considered the finest in the world. The other species, Russian, stellate, Persian and ship sturgeon have also suffered declines due to overfishing as well as habitat degradation in the Caspian Sea region.
