240502 Lake Sturgeon Release 02This juvenile lake sturgeon was one of 50 released into the Tennessee River from Chattanooga’s Coolidge Park on May 2. The lineage of the fish can be traced millions of years, but overfishing, dams and habitat destruction has led to widespread population declines throughout its natural range.  Doug Strickland/Tennessee Aquarium

Lake sturgeon recovery links rivers and experts in Tennessee and Wisconsin

CHATTANOOGA — Just across from the iconic peaks of the Tennessee Aquarium on the shore of the Tennessee River, a group of scientists with the Tennessee Aquarium Conservation Institute gathered on an early May morning to restore a primordial fish to the state’s primary waterway.

One by one, they carefully navigated down a boat ramp at Coolidge Park before gently releasing juvenile lake sturgeon, each just under a foot in length, into the river’s shallows.

These 50 sturgeon were the final youngsters to be reintroduced from a class of hundreds of sturgeon fry that arrived at the Conservation Institute’s freshwater field station last summer. Their introduction to the Tennessee River represented the latest milestone of a decades-long conservation effort to restore this state-endangered fish.

Despite reclaiming their one-time home in the waters of the Volunteer State, these newfound Tennesseans began life some 850 miles north of Chattanooga.

Join in a great event on Saturday, Oct. 7 for Sturgeonfest 2023 where you will have the opportunity to see the release of baby sturgeon into the French Broad River.
 
When: Saturday, Oct. 7, 2023 from 10 a.m. to 2 p.m.
 
 
The sturgeon release will begin at 11 a.m. and there are 1,000 baby sturgeon to release.
 
Due to habitat degradation, barriers to migration, overharvest and pollution, lake sturgeon have been almost extirpated from much of the Southeast US for more than 50 years.
 
In 2015, the N.C. Wildlife Resources Commission joined surrounding states in the Southeast Lake Sturgeon Working Group in an effort to restore lake sturgeon to the Tennessee and Cumberland river systems.
 
Brood stock comes from the Wolf River in Wisconsin, where the U.S. Fish and Wildlife Service works with Wisconsin Department of Natural Resources to collect eggs and milt for transportation and hatching at the Warm Springs National Fish Hatchery in Georgia.After hatching and growing, lake sturgeon are sent to the USFWS National Fish Hatchery at Edenton, N.C. and the Wildlife Commission’s Table Rock State Fish Hatchery for several months before release.
 
Approximately 2,000-9,000 juvenile lake sturgeon have been stocked annually in the French Broad River since 2015.
 
Dylan Owensby of the U.S. Fish and Wildlife Services says lake sturgeon are slow-growing, long-living fish. They might live up to 150 years and can grow more than 6 feet and up to 200 pounds. Females mature at 14 to 33 years of age and reproduce only once every four or more years. Males mature at 8 to 20 years of age. Sturgeon are bottom dwellers feeding on larval insects, crayfish and mollusks.
