our pond is 1.5 acres, recently added aeration professionally installed. Pond is about 7yrs old(rebuild busted dam) and was stocked with large mouth , blue gill, channel cats, shell cracker and a few grass carp. Chain pickerel are in there naturally as well. Also an otter or 2 regularly show up. I want to put crappie in there but i keep reading that they will out compete the bass because large mouth arent aggressive enough, but what I havent seen is any mention of the pickerel. We joke and call them "fresh water barracuda". I also love pan fried crappie. Will the barracuda, otter, and myself be enough to manage crappie in this pond? btw.... I am also putting out about a 40lb bag per month of "floating catfish food" from 2 different piers. Pond is spring fed and the water has never stopped flowing out the overflow pipe.
