Bob, on the same topic (I think)I just stocked a 3/4acre pond with 100black crappie and 100 channel cat 8lbs of fathead minnows...Now saying that, my wife just purchased 4 muskogee ducks for the pond.My question is this..Do the ducks eat fish or just the algea and feed we give em? WE were told the keep the pond clean of weeds...
