Officials warn about algae found in western MA

Posted: Updated:

Officials from the Massachusetts Departments of Fish and Game and Conservation and Recreation have been warning residents about an invasive algae that was discovered in the state in May.

According to DFG officials, Didymosphenia geminata, or didymo, was recently detected in the Green River in the Berkshire County towns of Alford and Egremont.

"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," DFG Commissioner Mary Griffin said in a press release.

According to environmental officials, didymo is a freshwater algae that occurs in North America and generally favors cold, clear, nutrient-poor waters with a neutral or slightly basic pH. In addition, didymo blooms can produce a dense covering on rocky substrate and eventually result in long, unsightly stalks.

Didymo may appear gray, brown or white and a texture comparable to wet wool or cotton balls. Officials said that extensive blooms can cover river substrate, and could temporarily impact aquatic habitats.
