Another good way to cull fish in a large BOW is to have a charity fishing event.
I have worked as a volunteer at some. If you want to see some big smiles, then load up a kid in a wheelchair onto the front platform of a bass boat. After taking about thirty 9" bass off the hook for them - you will have a great big smile too!
If you really wanted to do it right, I know Freedomeagle hosts some fishing events for injured vets at his ponds. I bet you could contact him via PM if someone on your end wanted advice on the organizing.
If you determined your culling needs, then you could pre-fish before the event and determine the proper bait combination to remove your targeted fish.
I have put on small minnows when the target was primarily small bass. I have also put on tiny bits of worm when we wanted the kids to remove little BG and the green sunfish.
Of course, the kids will catch a little bit of everything. One time the kid in the boat beside us caught a 4# channel cat on the little ultralight he was fishing with. He needed some help to fight the fish, but his he was awfully proud when the fish was on the deck!
Best wishes,
