First and foremost, Mitch, you need to remove those carp. Having 400 pounds of carp in a one acre pond is bad news. I imagine water clarity is very poor.
Your best bet, honestly, is to completely kill this pond. If you can, I would drain it, deepen it another 6 feet or so, make sure everything that was in it previously is gone. Then you'll have a clean slate and entertain those out of the box species you want.....
I agree, you need to remove those carp!
Catch them - not difficult in turbid water - chum them with fish pellets, corn or bread scraps - toss a baited hook and hang on -
Kill off the pond for 20 carp - you gotta be kidding....
...
Carp are now being classified as highly regarded sport fish and are sometimes called "Golden Bones" - in reference to saltwater bonefish!
20lb trophies - wish I was close enough to help "eradicate"!
