I think mine are just now kick'en off. I have numerous ponds with them including my two main bass growout ponds. One of those shows no signs. The other had about 25 water-turkey's on it. I ran them off and drove up to see about a dozen dead tilapia floating and 1 of my prize grown Florida bass. Alright, look I don't mind them eating up the dead Tilapia, but they crossed the line with the bass. I will be taking "preventative measures" tomorrow. LOL
