Boils on trout
Was out yesterday, and about a third of the trout I caught, had what looked like boils on their bodies. Not open sores but dime size lumps. With the heat I did not want to handle and take time for pics, didn't even net just grab hook and quick jerk and off. Fish were feeding heavy in the heavy weeds where you could not get at them, was blue green in the weed tops. Anybody know what that was and if it's related to the blue green?
