    A war in the water

    Eastport, Mississippi — This stretch of the Tennessee River is considered the most aquatically biodiverse in the nation, teeming with sportfish and at-risk snails and mussels. Locals boast that Pickwick Lake, where Mississippi, Alabama and Tennessee come together, is “the smallmouth bass capital of the world.” Catfish and buffalo fill commercial angler’s nets. Marinas lining the reservoir’s roads attest to Pickwick’s huge economic impact. Yet the Tennessee River, and a way of life, is under siege.  Learn more...

    Lake sturgeon restoration in the Upper Tennessee River

    June 7, 2017 | 2 minute read

    The Warm Springs National Fish Hatchery works cooperatively with partners that include numerous states, non-governmental organizations, universities, and federal agencies to achieve restoration goals for lake sturgeon in the upper Tennessee and Coosa Rivers in the southeastern United States. Warm Springs National Fish Hatchery has been involved, since 1998, with lake sturgeon production to improve culture techniques, feeding, fish health, habitat assessment, and telemetry studies. Hatchery staff members Carlos Echevarria and Chad Shirey traveled to Shawano, Wisconsin, in April to spawn lake sturgeon in the Wolf River, and transport fertilized eggs back to Warm Springs.  Learn more...
