The Connecticut Yankee blog reports on the recent discovery of the invasive algae Didymosphenia geminata, also known as “rock snot”, in the West Branch of the Farmington River. The bloblike algae, which forms large, disgusting mats of goo on the bottom of river and streams, chokes off endemic plants and destroys the natural habitat of many aquatic insects.

Here’s an excerpt from the blog:

“Perhaps it was only a matter of time, but troubling news reverberated throughout the local angling community last week. An invasive type of algae, Didymosphenia geminata, or didymo for short, was positively identified in the fabled West Branch Farmington River. This is the first confirmed report of didymo in Connecticut waters, but it has been plaguing trout streams in the Northeast since 2007.”
