Scientists scrutinize virus, contaminants in smallmouth bass die-off
Bay Journal — by Donna Morelli — July 5, 2018
Biologist Vicki Blazer of the U.S. Geological Survey Leetown Science Center has been leading a long-term study of wild bass from the Susquehanna. Her team of federal and state researchers have been working on the premise that multiple infections of disease and parasites caused the widespread deaths of young smallmouth bass that were first observed in 2005. Those infections, she argues, may have been triggered by a brew of chemicals polluting the Susquehanna that weakened fish immune systems.
