I had all sizes in the fish I took out from this kill. Probably two thirds to three quarters of the floaters were BG - and I would say only a third of these fish, at most, were what I would call "keepers" if I was fishing. I know I have several bass in there that are around 3 lbs and I have only seen one of those floating.
So maybe the good fish did die and just sunk instead of floated? Nice thought...very encouraging..
On the weird side I did discover I had an over 3' grass carp. I didn't even know I had it in there... At first I thought it was basszilla when I saw it floating.
