Pond Boss Forums STOCKING A NEW POND Types of fish to choose Only fish necessary for pond health

I have a newly cleaned pond and kids are requesting no fish. I think the bluegill had gotten out of control and they were often bitten pretty hard, I also was torpedoed in the back once (possibly a careless bass lol). To my knowledge we had bluegill, bass, perch, and grass carp. So, what fish are necessary to keep the pond healthy, but the least of a nuisance to swimmers? We are in NW Ohio and do have pet ducks, if it matters. I am also planning on buying a new fountain/aerator to keep it as healthy as well.
