Fishing for carp is very under-rated in the USA. In several countries in Europe, carp is king. They grow large, fight very hard, and can be difficult to catch.
Nightcrawlers are usually good in most open water situations, but at times other bait works as well or even better. There are several carp baits on the market now and I suspect they probably work well some of the time. We used to fish for carp on Lake Zumbro with corn and nightcrawlers on the same hook. I’ve had carp hit jigs on several occasions. Good luck and let us know how your fishing goes.
Good Fishing,
Mike
