Well If your looking to remove bluegill you can try this technique I use for my 1/8 acre pond. I use fish traps/minnow traps off of my small deck in my pond to control the population in my pond. After spawning, etc.. But, my pond is very small and I got bluegill, channels, red ear, and maybe 15 bass. It works for my pond prolly cause it's so small and I can see when there are too many hatched fish, esp. the bluegill. I started doing this for the bluegill these thnigs reproduce worse than rabbits. I started this after the first spawn and my bluegills are almost 1 lb in size and only stocked 2 years ago. so try it out it may help...
