Invasive and Now Not
July 1st marked the end of a ban on the use of felt-soled waders in order to prevent the spread of a type of algae called “rock snot.” The algae were thought to be invasive in the Northeast, but researchers have now concluded the aquatic algae are in fact native to the northern United States.

The aquatic algae, Didymosphenia geminata, have caused massive blooms in some U.S. rivers. Fishermen spotted it in rivers in Vermont in 2007, sparking alarm.

The algae, also known as didymo, attaches to rocks in river bottoms and has been described as resembling a sewage spill. It prefers pristine, low nutrient rivers. In its early stages, it forms nubby brown growths on rocks and later develops a woolly texture.

While the waders may be used again on July 1, the Vermont Fish and Wildlife Department is urging anglers and others to clean and dry all equipment after leaving any body of water and before going to another one to prevent the spread of aquatic invasive species that can sicken fish.

Minnesota aquatic invasive species control - Minnesota DNR is stepping up efforts to prevent the spread of aquatic invasive species. Armed with tougher laws and more costly penalties for violators, the DNR will staff portable “stop-and-inspect” stations as well as portable “decontamination” boat washers to spray down watercraft and trailers thought to be carrying invasive species such as zebra mussels, Asian carp, round gobies, spiny water fleas, and Eurasian watermilfoil.
