My philosophy with my limited knowledge is: Feed the best stuff while the fish are small, then feed the cheaper stuff, like catfish pellets. From what I have read, immature fish get more benefit from high quality, high protein food, and this benefit diminishes as the fish mature. My 6" CC grew to near four pounds in one year by doing this, and my stocked BG to breeding size (and nearly eating size) the same way. Once you have mature fish, they might eat most of the food anyway, so the small ones might have less benefit.
