Do what I did. It is expensive but well worth the money. My new 7 acre pond somehow got full of green sunfish and crappie. With my stocking plan blown, I purchased 85 one to three pound bass. They knocked the numbers down dramatically. Not only does this work fast, but you have large fish to catch and enjoy. I bought my fish at Insleys Fish Farm in Connerville. Go see Theop and Donald, they will even let you catch your own fish out of their holding pond. Believe me , catching 85 one to three pound bass will wear you out.
