With the October 27 opening of the Tennessee Aquarium Conservation Institute’s (TNACI) riverfront facility, the Southeast’s rich – but imperiled – aquatic biodiversity is going to receive a much-needed shot in the arm.
Located near a natural wetland along the banks of the Tennessee River downstream from downtown Chattanooga, the 14,000-square-foot facility will serve as the headquarters for a newly expanded staff of conservation scientists as well as visiting experts. Featuring an environmentally conscious design, the building provides access to cutting-edge equipment, including morphology and genetics laboratories, and offers much-needed space for staff to centralize and streamline ongoing projects, initiate new research, and host educational programs.
“We’re surrounded by amazing animal communities in our rivers and streams,” said TNACI director Dr. Anna George. “It’s why our region is so exciting to the scientific community and why we’re committed to protecting our aquatic treasures so they can continue to be enjoyed by all. This new science center will give us more capacity to expand our research, restoration, and education programs.”
Since TNACI’s foundation in 1996, its staff has pursued projects to study and, in some cases, restore, some of the region’s most imperiled species, including long-term captive propagation of Lake Sturgeon and Southern Appalachian Brook Trout. Previously, those programs were managed at separate off-site locations, some more than 45 minutes away from Chattanooga. They now will be housed on the first floor of the new building in a space specifically designed for the animals’ needs. Even with the newly relocated programs, additional square footage has been reserved at the site to expand TNACI’s propagation efforts in the future.
The building’s dedicated genetics laboratory will simplify the research process and increase the capabilities of TNACI staff. Formerly, institute researchers conducting DNA testing worked at a makeshift station in a corner of the Aquarium’s Animal Care Facility.
By bringing together formerly far-flung projects and offering access to lab equipment that can more effectively handle research needs on-site, the new facility eliminates many of the obstacles that previously hampered TNACI’s conservational efforts, said Dr. Bernie Kuhajda, director of TNACI’s science programs.
“Just getting together to work collaboratively with our team was always logistically challenging since we were in separate buildings,” he said. “Now we’ll have all of our field gear, labs, and offices in one place. A huge benefit is this new shared space, which not only helps us work together more closely, but also gives us space to bring together fellow scientists from across the country to discuss conservation solutions.”
Although it is just now opening its doors, the new facility already is the hub of numerous active conservation programs, including:
An ongoing population analysis and newly funded genetic study lead by Kuhajda and George of the Laurel Dace, an endangered fish whose habitat is restricted to a small system of waterways on Walden Ridge.
A new study funded by a U.S. Fish and Wildlife grant to establish the population genetics of the Cumberland Darter, an endangered fish found in only a handful of tributaries of the Upper Cumberland River in Tennessee and Kentucky.
A three-year project initiated earlier this summer by TNACI aquatic biologist Dr. Josh Ennen in partnership with the Tennessee Wildlife Resources Agency and Southeast Missouri State University to study and determine the conservation status of Alligator Snapping Turtles in Tennessee.
A new on-site program utilizing an artificial stream with controllable water temperatures to gauge the potential impact of climate change on salamanders and other small stream species.
An ongoing survey initiated in September and lead by Dr. Kuhajda of six threatened and endangered fish species living in the Mobile Basin, including the Blue Shiner, the Cahaba Shiner, the Goldline Darter, the Rush Darter, the Vermillion Darter and the Watercress Darter.
In addition to its scientific initiatives in the field, TNACI’s new facility also will serve to bolster the institute’s educational outreach. A large teaching lab on the first floor will target regional high school and college students who hope to pursue – or who are pursuing – a degree in a scientific field and connect them with freshwater scientists and educators.
The site also will serve as a nexus for conservation science beyond Chattanooga, with office and research space on the second floor designated for use by visiting scientists.
More than 1,400 aquatic species reside in waterways within a 500-mile radius of Chattanooga, including about three-quarters (73.1 percent) of all native fish species in the United States. More than 90 percent of all American mussels and crayfish species live within that same area, as do 80 percent of North America’s salamander species and half of its turtle species.
