Hey, lets all get together over a beer and try to design a miniature depth charge rack that can be bolted to fishing boats. The depth charges would be the size of a beer can. Using the fishfinder to locate schools of these asian invaders, you'd make one pass over them rolling depth charges, give the water time to settle again, then come back and fish the spot you "prepared". The cats would probably be stacked up there, feeding on the "chum" created by "preparing" the Asian Carp.
