Biologists investigate mass die-off of freshwater mussels
In recent years though, biologists and fisherman noticed something was wrong. On sections of the Clinch and other waterways in the Pacific Northwest and Midwest, dead mussels were turning up on shores and could be seen glinting from the river bottom. … “The loss is really huge and it’s happening really quickly,” says Emilie Blevins, a conservation biologist with the Xerces Society for Invertebrate Conservation. “It’s a major concern for the future and for the future of our fresh water.”
