Bass are 100% predator and will eat enything smaller than themselves. I'd have to ask my brother where it is but a pond in Mississippi has ONE bass in it and several brim/perch and very little cover/grass etc for any of them. It is a swimming hole and I have been under water in it watching the bass and brim. It is just under an acre in size.
If you do this, know that either you feed them or they starve because a pond that size won't support but a pair of brim and the feed minnows to go/w them and be self
sustaining. But...you can put in a divider made of a wall of congested brush with the floating Hortworth on the smaller side of it and then the minnows/shrimp can actually breed/multiply enough to feed the fish and the pond would need practcally Zero maintenance/air/filters etc.
You can then throw in any food you like but not have the pond dependant on it.
You can do this any way you like but you won't need that big bucks breeding opperation to have the pond as I suggested...your choice.
In this case you could put in what are called Goggle Eyed perch/Rock Bass(same fish)
that get fairly large (don't know exactly but like 7") and from the name you can guess that they look almost like a Bass and are just as predatory and only eat live food. Other brim can be taught to eat pellets. They can by bought from here.
BTW my brother has pond for years and uses an extension cord to heat it and run his fountain pump. He has a common Pleco living in it all year and it gets down in the 50's in the winter in it. Maybe even less. But he just has one of those plastic Loew's ponds.
It is two tiered and the Pleco actually goes up to the top level up the water fall whenever he wants to.
