Eastland,
your thinking is right its just tough to get enough large catfish in a pond to eat 12 inch stunted bass. I have seen small ponds that have big problems when stocked with too many catfish. once CC get big they will eat up most everything, the only fish you have left are the big 10-15 pound cats. so in theory you are right but in the real world its impossible to predict how many large catfish it will take, I've never seen any research on the matter. then where do you get catfish that big? if you buy stockers you have 4-5 years of feeding to do to get CC up large enough to help you eat bass. thats 5 more years of bad bass fishing. then what happens if you stock too many catfish? now you have catfish to remove instead of bass.
A 30 acre lake is very diverse, there is a strong possiblility that the CC will find a more suitable food resourse than 12 inch bass. If that happens you are back to where you started.
I'll kill myself before I'll stock a flathead into someones pond. they will wipe it out, I've only seen it once but the flatheads totally wiped out he pond. they are a predator unparrelled by any other in freshwater except maybe a pike or muskie. we dont have those fish around here so the flathead is very near top of the food chain. No way do I want that big ugly thing eating up all my fish.
Blues? dont know never stocked one
there are more factors to consider than just adding another predator. your best bet is to remove those little bass. the others will grow. If I had a pond in south Ga. that I wanted big bass in I would adjust the bass population and stock shad, threadfin to start then gizzard. now you've got the nuts, as the poker players say
