A couple of rules of thumb also have to be considered. The "average" pond will support about 100 lbs of predators per acre. Intense and knowing managers, like Meadowlark, can push it to a higher level. But, it's a lot of work and the stars have to pretty well stay aligned in the heavens. We call that luck, management, and clean living. Water quality and the right forage are the keys to the predators success. Aeration can be a huge insurance policy in the water quality part of the equation. To thrive and sometimes even hold its own , a big bass needs to eat forage that is 1/4 to 1/3 it's length and size. It's a matter of energy expended vs calories received. Annual tilapia additions can help here.
As Meadowlark and I have both experienced, big fish in a one acre and/or smaller pond also become hook shy if you try to fish it over 3 or 4 times per year. Is it worth it? you be the judge on your energy and $ expended vs fun.
It is also better to raise the bass in the pond. Transplanting big bass can be problematic. Most that I've seen transplanted don't thrive or sometimes even survive.
