I have stocked quite a few lakes and ponds with adult bass. Stocking adult bass at a rate over 20 fish per acre will result in an extremely bass heavy population in about 2 years. Of course these are Georgia ponds and not Indiana. You may have better results up there. I would recommend cutting that rate in half. 12 bass per acre. If you are unhappy with results you can always add more.

I'm not sure about the carring capacity for a pond up there. here in an unfertilized pond its about 100 pounds per acre. For arguments sake lets say your pond will carry 200 pounds per acre. that means your pond will hold 200 pounds of fish. it doesnt matter if its 200-one pound fish or one 200 pound fish, that is all the pond will hold. Now you stock 12 bass per acre and want them to grow. You will need 120 pounds of forage for those 12 fish to grow one pound. They will consume just over half the forage in the pond that year to grow one pound.

Now consider stocking at a rate of 25 fish per acre. It will take 250 pounds of forage for your fish to grow. The problem is you dont have 250 pounds of fish in the pond. Thats assuming your carrying capacity is 200 pounds per acre. Stocking 25 adult bass per acre into an unfertilized pond here in Georgia will result in skinny bass. My advice if you want good bass growth is to take it slow, add a few bass at a time and see what happens. they will help you control crappie and other unwanted fish. this method will also keep you from having to remove several hundered small stunted bass.
