I have a large pond (dug out by a large bulldozer and would guess larger than 1/4 acre size but really deep) and I have 3 pair of swans, several geese and ducks. my que is, I want to put some fish in the pond and want to make sure that what ever I get will not hurt my swans (babies due next week). I put 5 Koi in it last year (only see them every once in a while) and 6 grass carp in it the year before when I had duck week problem. When the fish truck come, my choices are Channel Catfish, largemouth bass, redear, bluegill (bream), minnows, black crappie, grass carp, koi. Now, these all are not available at all times. last time they were out of the large koi and only had small ones and they told me the big ones would eat the small ones so I didn't get them.
we will not be fishing in the pond, so they are just there to swim around.
