All the BG are about hand size and the LMB are generally 2# but I saw one LMB that could of went around 3.5#. We have never had fish die like this so it just seems weird to me. I sort of assumed it had to do with the spawn. I think my pond is at the tail end of the spawn here in NE Ohio. That super moon is what started it off as far as I could tell. As for that white lip thing that was on BG that were still alive swimming around. I don't know if that is like a clue or what but they looked really weird.
