I agree that feeding the fish is the fastest, easiest way to put a big belly on your fish. I use four or five feeders on my smaller pond and the fish around the feeders will be much bigger then the areas where I do not feed. After Cecil wrote about his pigs( he can really grow all kinds of fish) having fatty cells and imperfections in their innards, I would not eat any fish fed these high fat diets. This is only my view but I have donated the last thirteen years battling(it is winning) cancer. If you want to grow them to be big this is the way to go but I do not think it would be good to eat these fish at all. We only eat crappie(they eat shad) so I do not think they will hurt you but I would never feed these huge, obese fish to anyone. I hope everyone has a full pond loaded with lunkers.
