CHATTANOOGA — The approach of summer coincided with the arrival of thousands of juvenile lake sturgeon in the Tennessee Aquarium Conservation Institute. 

Biologists at the Aquarium’s freshwater field station welcomed 2,500, 2-inch babies into their care. After a steady diet of bloodworms and brine shrimp, bringing the fish to at least 6 inches, they will be reintroduced into the Tennessee River.

These tiny fish hold tremendous promise. Adult lake sturgeon may reach lengths of 8 feet and live 150 years. 

“They start out really small, so it’s shocking to think how big they can get,” says reintroduction biologist Sarah Kate Bailey. “The first year of life is when they grow the quickest. 

“They grow so fast while we have them here. You’ll go home for the day, come in the next morning, and they look like they’ve grown overnight.”
