Thanks for the replies. The kids and I fished this past weekend and caught mostly hybrids and yes quite a few Sun Fish. After catching some of the fry, I determined they were in fact Sun fish. Not sure how they arrived, however I know it happens.

Of course my air diffuser is in the deepest part of the pond and run 24/7.

Thanks for the links for the Winter aeration I want my giant Largemouth bass back! My 12 year old did manage to pull a 5lb. 6oz. Largemouth out. He wasn’t happy when he had to let him go! He knows that is a big Bass for Michigan.
