On October 13, 2026, the Tennessee Aquarium will hold a public event at Coolidge Park to release 500 juvenile Lake Sturgeon into the Tennessee River. This initiative marks the 26th year of efforts to restore the state-threatened species to its native waterways.
Why it matters
The reintroduction program aims to reverse the decline of the Lake Sturgeon, which disappeared from the Tennessee River due to historic overfishing, damming, and poor water quality. The last wild-born sturgeon in the region was recorded in 1963.
The 500 juvenile sturgeon measure between six and 12 inches long and were raised at a freshwater field station from eggs sourced in Wisconsin. Since the program began in 2000, 430,000 sturgeon have been released into native habitats.
The players
Tennessee Aquarium
An organization based in Chattanooga that manages aquatic exhibits and conducts freshwater conservation research.
Tennessee Aquarium Conservation Institute
A research entity focused on the recovery of aquatic species and the protection of native freshwater ecosystems.
Southeast Lake Sturgeon Working Group
A collaborative organization established to coordinate the restoration of Lake Sturgeon populations in the region.
The details
Biologists at the Tennessee Aquarium Conservation Institute raised the juvenile fish over the summer at their field station to prepare them for the river environment. The project follows the formation of the Southeast Lake Sturgeon Working Group, which launched in 1998 to address the population collapse.

Culture Shift
This release continues a long-term conservation trend aimed at restoring native species that were decimated by industrialization in the 20th century. It mirrors ongoing efforts across the Southeast to restore biodiversity in watersheds previously altered by dams and overfishing.
Residents can observe the fish release firsthand at Coolidge Park on October 13. The program relies on public awareness to support ongoing water quality improvements in the Tennessee River.
The takeaway
The return of the Lake Sturgeon represents a significant milestone in restoring the native biodiversity of the Tennessee River watershed. Public involvement in these release events helps track the species' progress toward establishing a self-sustaining population.
