The invasive freshwater alga,
Didymosphenia geminata, commonly called didymo, was discovered in the West Branch of the Farmington River. This is a very popular trout stream in northwestern Connecticut. Fishermen reported the suspected infestation which was then confirmed by the Connecticut Department of Environmental Protection in March, 2011. There is no known way to remove didymo once it has become established. Prevention by thoroughly cleaning clothing and equipment when going from one fishing location to another is the only way to stop it from spreading. Read the article by the
