My Answer: Common carp are omnivorous and will eat water plants, but they seem to have a preference for insects, crayfish, and worms. They also like corn--a lot. Perhaps the simplest way to catch carp is to use a bottom-bouncer rig. Tie on a fairly heavy egg sinker about 8 inches above a No. 8 snelled hook. Pack the hook with as many corn kernels as will fit, cast, and let it sit. It sometimes pays to chum the hole that you're intending to fish a day or so ahead of when you plan to fish.
