Pond Boss Forums INTRO Questions & Observations Stocking an already populated pond.

Bill D. and Arktiger. The sunfish is a green sunfish.

Rex is getting old, his eyes are going and he has a small screen on his phone.

If you want to turn that pond into a LMB pond, you don't have to kill or remove them. Just stock advanced sized LMB at least 8"-10" or larger fish at 50 - 75 per surface acre. The GSF will eat fingerling LMB, so there's no point in stocking small ones. Wait until the LMB have chowed down on the GSF for a while before stocking BG, but then if you do you have to stock advanced sized BG to prevent the stockers from getting eaten by the LMB.

You could drain both ponds, either with a large trash pump or via the overflow if you have a valve on it. Then kill the remaining water and any wet spots in the pond bottom with either hydrated lime or rotenone.

Unless you want to do a lot of management (i.e. removing fish yearly) don't stock crappie. If you want to turn that other pond into a Channel Catfish pond, you might not have to drain and kill it, but the bullheads in there will be competing with the Channel Cats for food. Bullheads have rounded tails, Channels have deeply forked tails. BH are black or brown on top turning to white or yellow on the bottom. CC are silvery/blue on top usuallywith spots on the smaller ones turning to white on the bottom.
