You know how many are in there. IF, IF you can fish them out before any spawn it might work. Get your dad and nephews to come back pronto and get busy fishing. Use primarily live bait, worms, crickets wax worms on small hooks. Put a bounty on the fish of $1.00 to $2.00 ea providing they can catch all 27; $0 if they don't get at least 26. Then we will see how good of anglers they are! You have to get them BG out before they build a nest and spawn. Otherwise nuking the full pond will cost about $200-300/acre to kill it with rotenone - license required. Other option is to pump or siphon out the water and treat the last 4"-8" with a heavy dose of hydrated lime or chlorine. I don't like the chlorine method due to creation of trihalomethanes.
