BOSTON, Mass (WGGB) – Officials from the Massachusetts Departments of Fish and Game (DFG) and Conservation and Recreation (DCR) say Didymosphenia geminate (didymo) or ‘rock snot’ as it’s sometimes called was recently detected in the Green River in the Berkshire County towns of Alford and Egremont.
This finding is the first confirmed occurrence of didymo in Massachusetts.
“The Department of Fish and Game and its Division of Fisheries and Wildlife are trying to inform the public as quickly as possible about the recent discovery of didymo in Massachusetts, and provide best available information about how to help prevent the spread of this freshwater algae,” said DFG Commissioner Mary Griffin.
Didymo can produce dense, slimy coverings on rocks and may appear gray, brown or white.
Extensive didymo blooms may cover stream bottoms, and make swimming, boating and fishing difficult and/or less desirable.
Although there is no known method for eliminating didymo from a waterway or controlling a bloom, all recreational boat users are asked to wash their equipment, clothing, waders and boats in hot, soapy water.
