Similar to sharks, Gulf sturgeon have tails where one side, or lobe, is larger than the other. Most barriers have the same general impact on fish—blocking migrations—but each requires a specific set of conservation actions.NOAA Fisheries and the U.S.
Tagged fish have been found in well-oxygenated shallow water areas that support burrowing macro invertebrates.
They have five major rows of dermal "scutes,” or thorny plates along the length of their body.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). Because of its success and research partners’ willingness to continue these efforts, additional funding for this project has been secured over the last several years.
Map and GIS data representing critical habitat for the conservation of… During the second year of our study, we recorded a total of 94,244 detections. Dredging operations may also destroy benthic feeding areas, disrupt spawning migrations, and resuspend fine sediments causing siltation over required substrate in spawning habitat.
Fish and Wildlife Service co-manage Gulf sturgeon.
Over the last several years, this research has provided valuable insight into Gulf sturgeon behavior and habitat use, as well as the necessary data to conduct mortality estimates and stock assessments in future years.Other ongoing work includes the assessment of estuarine habitat-use patterns by juvenile Gulf sturgeon, as well as trends in juvenile sturgeon recruitment, growth, survival, genetics, and kinship across the range of the species.Scientists use various tagging techniques to learn about the migration patterns of Gulf sturgeon and to identify important juvenile habitats.
Ancestry: Sturgeons are an ancient group of fish dating back about 200 million years to the age of dinosaurs. Juvenile Gulf sturgeon (304-890 mm FL) stay in the river for about the first two to three years and then move to the estuary where they forage until they reach sub-adult sized (891-1250 mm FL or three to four feet). Female Gulf sturgeon reach sexual maturity at 8-17 years of age. Gulf Sturgeon Facts Sturgeon: An ancient type of fish, with 5 rows of armor scutes, a cartilaginous skeleton, long snout, suction mouth, no teeth, and 4 barbels.
In the future, those baselines will allow sturgeon to be identified back to their natal river. Subadults and adults do not feed when they are in the river.
Removing outdated dams can greatly improve Gulf sturgeon access to historical habitats.
Acoustic and satellite telemetry tags (tags that use radios to locate) let researchers learn where Gulf sturgeon migrate, at what depths, and at what speeds.Gulf sturgeon researchers take small fin clips from every sturgeon they catch to better understand the genetic composition of all populations.
We conduct various research activities on the biology, behavior, and ecology of this species.
