DEEP Fishing Report – December Updates

DIDYMO – Invasive alga again found in the West Branch Farmington River.

The invasive freshwater alga, Didymosphenia geminata, known as “didymo” or “rock snot”, was first found in the West Branch Farmington River in March, 2011. Interestingly, didymo was not found in the West Branch during spring, 2012. This lack of didymo may have been due to the high flows that occurred in late summer and fall, 2011 that scoured the substrate. However, in late November, 2012, DEEP staff did again find a fairly dense bloom of didymo at a site on the river in the Riverton area. These remain the only reports of didymo in Connecticut.

Didymo is typically found in cold, shallow streams with rocky substrate. The microscopic didymo cell produces a stalk to attach to the substrate. Under ideal conditions, blooms of didymo can form thick mats of stalk material that feel like wet wool and are typically gray, white and/or brown, but never green in color. These mats form on the bottoms of rivers and streams, and if dense may have negative impacts on the ecological, recreational and aesthetic values of rivers with suitable habitat (cold, rocky, well-lit areas).

Anglers, kayakers and canoeists, boaters and jet skiers can all unknowingly spread didymo. The microscopic cells can cling to fishing gear, waders (felt soles can be especially problematic), boots and boats, and remain viable for months under even slightly moist conditions.

Numerous clumps of didymo were found in the West Branch Farmington River in spring, 2011. Although not found during spring, 2012, DEEP staff recently (late November) found a didymo “bloom” in the river just below Riverton.
