Pond Boss Forums INTRO Questions & Observations Cyanobacteria (blue-green algae) toxin

Quick bit of research reinforced the role of warm, stagnant, nutrient-rich water in cyanobacteria blooms. Thus, systems that move water & help cool near surface areas should be helpful, as would floating islands that take out excess nutrients. Also, of course, it is smart to see if nutrient load can be reduced at the source(s) in the watershed.

Even with liming & fertilization, I struggle to get a good phytoplankton bloom, but maybe that's not entirely a bad thing as it also means less danger of cyanobacteria bloom. As for the airborne toxin, I remember reading years ago a claim that even walking around a lake infested with blue-green algae could cause amyloid plaque brain changes similar to Alzheimer's, though I haven't seen much on that since then.

PS I wonder if filter feeders like paddlefish or threadfin shad might be useful? Or perhaps vigorous harvest of other fish might help remove some nutrients. Another reason to take out LMB?
