My pond filled up really fast and it took a couple of weeks before I could get fish until last Thursday. The pond already had a lot of baby crawfish, tadpoles and a bunch of frog eggs. I am hoping the fish with eat the growing food supply. I stocked 75 bass, 300 catfish, 350 bluegill and 10 lbs of minnows. Since Monday their have been 5 ducks in the pond, should I run them off or are they able to help control the frogs and catfish with a limited amount of fish before moving on.
