Late yesterday I caught a few CNB from our 70 acre lake directly in front of my feeder. We have 11 feeders and only mine is feeding year round. All of the CNB had some type of ulcers on them, with some being infected more than others. I was going to go out this morning to our other feeders to sample more fish but the temps had dropped and the winds were howling. Can anyone give me a guess as to what this might be and is there any control over it. PS I don't think it has anything to do with handling the fish because we rarely fish for Bream. Also have seen no mortality of our CNB.
