I have two successful fish ponds based on the great info that folks have provided here (BG/LMB & YP/SMB). My 3rd pond will go off course a bit with crappie and catfish in a 0.4 acre pond, but I am going in with my eyes wide open. Nothing but FHM and lake chubsucker in the pond now and I am still hoping that I can locate some blue catfish locally to transfer in rather than ordering CC. If things go awry, it won't be due to not being given fair warning. Just wanting a different mix of fish that will spawn. I do have a neighbor who loves to fish, so that might save me if the catfish cannot control the crappie. I could also perhaps add GSH to eat eggs if things start going downhill. Sounds like spotfins are really no advantage in this pond, but might work in a RES & grass pickerel pond since perhaps the breeders might be too big for most of the predators?
