Think about how amazing it is to see an American bald eagle soaring over downtown Chattanooga. Yet almost every day, within eyesight of the Tennessee Aquarium, these majestic birds are seen soaring overhead and even rearing their young. These sightings weren’t always so common.

In short, the law helps ensure that careful planning is in place so that future actions don’t threaten the existence of any listed species or cause the critical habitat of listed species to be destroyed or significantly modified in ways that would jeopardize listed species. The law also prohibits “taking” of any listed species of endangered fish or wildlife.

According to a USF&WS press release, today is the day to remind everyone about these animals and the ones that still need a helping hand. “Endangered Species Day provides an opportunity to celebrate our successes and strengthen our partnership with the American public to conserve our shared natural resources,” said U.S. Fish and Wildlife Service Director Dan Ashe. “By taking action to help our threatened and endangered plants and animals, we can ensure a healthy future for our country and protect treasured landscapes for future generations.”

The Aquarium is also a place where people can see endangered species like Conasauga logperch, Barrens topminnows, West African dwarf crocodile and the beautiful Palawan peacock pheasant. Many of the turtles on display at the Aquarium, like the yellow-spotted Amazon river turtle, are also endangered species. Even in the new River Giants exhibit you’ll find giant pangassius catfish that are listed as endangered species.

Many more Aquarium animals are “vulnerable” species like the toothy sandtiger shark, lined seahorse and many of the corals featured in the live coral exhibit within the Boneless Beauties gallery. Look for the status of species on the animal ID graphics near each exhibit on your next visit.

We hope our guests make a connection to these amazing animals while seeing them up close. Those connections help people better understand each of these wonderful creatures and why we should all be eager to protect them.

So, it’s with the enthusiasm of oceanographer Dr. Sylvia Earle that we celebrate Endangered Species Day. We can admire truly remarkable species with a special realization that it’s our responsibility to make sure they don’t disappear on our watch. “This is the first time in our history that we are capable of understanding our effect on the Earth’s atmosphere, the chemistry of the ocean, and the biodiversity of life. We’re the only species on the planet that can do something about it.” – Dr. Sylvia Earle

Inspiring Future Conservationists - By Ashford Rosenberg, Tennessee Aquarium Conservation Institute, TNACI, Sustainability Coordinator
There have been a lot of things to celebrate in April: Easter, Earth Day, the coming of spring. For us at the Tennessee Aquarium Conservation Institute and the Tennessee Aquarium, it was a month to celebrate milestones. The Tennessee Aquarium celebrated its 20th birthday and the opening of a new River Giants exhibit, and TNACI celebrated the continued success of the Lake Sturgeon Reintroduction program, one of our local river giants. Each year we release juvenile sturgeon that are about six months old and six inches long. Occasionally we hold fish a few months longer so that they can be released at larger sizes, which is exactly what we did this year.
Lake Sturgeon are very special fish that live in many rivers across the U.S. They are a river giant in their own right. The largest on record are 8 ft and 310 pounds, though now sizes of 5 ft and 100 pounds are more common. They can live up to 150 years and they do not reach sexual maturity until they are in their teens. While they are not listed as federally endangered, Lake Sturgeon are considered imperiled in Tennessee. In the 1960s, a combination of habitat degradation and overfishing caused the Lake Sturgeon to become extirpated from the Tennessee River. After some improvements in dam discharge practices as well as benefits from the Clean Water Act in 1972, a group of agencies decided to work together to bring the Lake Sturgeon back to the Tennessee River. The Tennessee River Lake Sturgeon Working Group partners include the Tennessee Aquarium Conservation Institute, Tennessee Wildlife Resources Agency, World Wildlife Fund, Tennessee Tech University, the University of Tennessee at Knoxville, U.S. Fish and Wildlife Service, Tennessee Valley Authority, United States Geological Survey, Wisconsin Department of Natural Resources, and Conservation Fisheries, Inc
On April 27th, we drove up to Nashville to meet up with TWRA and a group of students from Mt. Juliet, Tennessee. We met them at Shelby Park near Shelby Bottoms Nature Center in downtown Nashville where the Cumberland River runs through the city. Dr. Zeb Hogan, National Geographic Explorer and host of Monster Fish on the National Geographic channel was in town to help the Tennessee Aquarium open the new River Giants exhibit, so he decided to come along and help us with the release.

TWRA brought thirty fish that were 2-3 years old and ranged in size from 24-30 inches. They are still very young, and will not be old enough to spawn for at least another ten years if not longer. These fish were born at Warm Springs Hatchery in Georgia and some of them lived with the TNACI for a few months before they were taken to TWRA’s hatchery.
Each fish has a scute, the bony plate that runs along the side and back of a sturgeon, removed that designates how old it is. We do this so that when we catch the fish on monitoring trips, we can determine how old it is. To date, 130,000 juvenile Lake Sturgeon have been released across Tennessee.

We all had a great time! TNACI got to drive to Nashville in style in a River Giants wrapped Volkswagen Beetle.
The kids had a good time too. Many took the opportunity to touch these majestic fish before letting them swim away into their new home. We hope that this experience will inspire these students to be conservationists.
