Hello, we have a new pond finished last October in Northeast Louisiana built on a spring fed creek. It is full with water running through the spillway. We have these “globs” all along the shoreline - probably thousands of them. They are firm but pliable, and hold their shape. Picture is in my wife’s hand for scale reference. But they do vary in size. Is this Ophrydium Versatile? On another forum someone said it might be Cyanobacteria (Rivularia). Any thoughts? Is this something that needs to be dealt with? Not really looking for a pristine and clear pond, but also don’t want anything to take over and/or get out-of-hand. Thanks!
I agree that these gelatinous globs are very probably composed of the Cyanobacteria genus called Rivularia that has around 20 different species. It often grows in clear water that can have a good amount of calcium content. The gelatinous coating protects the Cyano (bluegreen) filaments in the colony and makes it difficult to kill chemically. I would not at this point try not to kill it. Let nature take its course. Be watchful of its development.
