Too many bluegill can't stunt bass growth because bluegill is the food source not the food competitor with bass. Too many bass in a pond will definetely stunt their growth. You don't want Florida anyway because 1: they don't grow big in Indiana, 2: they're hard to catch, much harder then the northern strain. What you will want is a mix northern breed called Tiger Bass, or a hybrid of a Florida strain and Tiger called Gorilla Bass. There was an article on this hybrid in bassmaster mag. last year. These fishes are supposed to growth faster then normal northern strain and as aggressive as a smallmouth. Ray Scott, I know how much we're all hate him right now, but he has a good video series called Great Small Water. Here is some info on the super bass. http://www.strikeking.com/journal/00022/1.php
