Dont chuck the carp back if ya catch one. Its illegal to return them to the water.
Corn kernels are ideal for carp. Redfin are just as much a pest fish as carp but you can throw them back but apparently they do taste ok.
If ya want to have a crack at lures buy a packet of soft plastic squidgies or similar brands.
You will end up with about 10 lures for the price of one hard bodied lure and in my opinion are way more effective especially for a novice. Just wind them in slowly and hope them a bit if you want.
