I guess I don't know enough to know if I have had a kill but have never seen any fish floating on the surface. I just assumed It was bass heavy with the small size LMB and big BG; I just don't want to take too many out if that is not the problem:

Don't know if this has to do with anything But after a big Flood 3 years ago the pond flooded into my backyard and the BG went crazy eating in the grass we caught them hard as long as it rained, then I found an eel swimming in the yard about 2 ft long thought that was interesting
