WOW 34"...for the flowage that's a monster! I don't know the scientific name (Blue help me out here) but it's called Black Spot. It's a parasite that is hosted by snails who are eaten by smaller fish who are a prey species for larger game fish. Each acts as a host. According to reports you can eat them, since cooking kills the parasite. I'm not sure if humans could be a host not. But, a)...not very pretty and b)...why chance it?
