Biologist studies mass mortality event of mussels in clinch river

U.S. Fish and Wildlife Service biologist Rose Agbalog sorts through the shells of recently dead freshwater mussels at Frost Ford along the Clinch River in Tennessee. In just a few minutes of searching she found recently dead fluted kidneyshell, cracking pearlymussel, birdwing pearlymussel, fanshell, Cumberlandian combshell, dromedary pearlymussel and oyster mussel. All are endangered species. The pheasantshell population is nearly gone at Frost Ford.
