Every day we impact water, and water impacts us.
The Tennessee Aquarium Conservation Institute (TNACI) furthers the Aquarium’s impact by conducting scientific studies, restoring our region’s natural ecosystems and educating members of the public to take conservation action.

Current Projects
Race for the Laurel Dace
The Laurel Dace, listed as federally endangered in 2011, is of great conservation priority as it is considered one of the top ten most endangered fish species in the United States.
In cooperation with The U.S. Fish and Wildlife Service, the Aquarium monitors Laurel Dace populations and habitat, works with landowners to promote best management practices, and raises awareness of the Laurel Dace’s plight through outreach events and media.
Saving the Lake Sturgeon Program
To date, the Aquarium and its partners, the Southeast Lake Sturgeon Working Group, have released more than 425,000 of these giants-in-waiting into the Tennessee River and Cumberland River. Hopes are running high that there will soon be signs that this ancient, long-lived fish has established a self-sustaining population in these native waterways.
Southern Appalachian Brook Trout
Southern Appalachian Brook Trout are the only native trout species in Tennessee. Aquarium staff are working with the Tennessee Wildlife Resources Agency and other partners to evaluate their status in the state.
Barrens Topminnow
Since 2001, the Tennessee Aquarium has worked to study and safeguard the Barrens Topminnow. In cooperation with Knoxville, Tennessee-based Conservation Fisheries, Inc., specialists from the Aquarium have monitored the few remaining populations in the wild, propagated and released more than 44,000 Barrens Topminnows and even occasionally rescued Barrens Topminnows threatened by prolonged droughts.
Ridges to Rivers
This project helps to implement land management practices that conserve natural resources and protect aquatic habitats.
Areas of Expertise: Freshwater Mussels, Field Biology, Grant Professional, Aquatic Species Conservation
In 2019, Stephanie joined the Tennessee Aquarium team after 15 years of working as an aquatic biologist for the federal government. She worked as a malacologist for the Tennessee Valley Authority before transitioning to the U.S. Fish and Wildlife Service, where she worked as a listing and recovery biologist for ten years. Throughout her career, Stephanie has worked throughout the Southeast, in collaboration with conservation partners to ensure the protection of rare aquatic fishes, freshwater mussels, and aquatic insects.
Stephanie is excited to lead conservation programs for the Aquarium and hopes her passion for freshwater species will inspire you to learn more about your local river or stream.
