Black bass hit the preferred live baits on the head for white perch. Grass shrimp and blood worms are hard to beat. Fish them on the bottom using a size 6 or 8 hook. I like using a typical tandem bottom rig you can buy at any sporting goods store. Use a 1/4 oz to 1/2 oz weight on the bottom and then pre snelled hooks for the arms of the rig. If there are white perch or any other small fish in there, they should tear that up... Even nightcrawlers will work, but not as well IME...

Those bass weights to lengths are bad... The bass definitely are not getting enough food. The lengths are longer than is typical with overcrowded ponds, which usually run 10"-14". Do you see any sunfish or any other smaller fish species in the shallows?
