Benthic Beasts: The Ecological Significance Of Lake Sturgeon And Blue Catfish In Eastern Appalachian Waterways, Stewart Thacker

Research Day

East Tennessee freshwater ecosystems comprise an abundance of an extremely diverse selection of species. This presentation examines Acipenser fulvescens and Ictalurus furcatus, two of the largest freshwater fish in the Appalachian area, which play significant ecological roles within the benthic dimension of our freshwater environments. Commonly known as “bottom-feeders,” Benthivorous species enjoy a broad range of food sources including other fish, detritus, crustaceans, and more. The extensive variety of food consumed by A. fulvescens and I. furcatus permits population control of other, denser, aquatic populations inhabiting other regions of the water column, as well as other organisms included …
