A lot of guys around here bow fish for carp. Some are way into it and have bows set up with reels designed specifically for bow fishing. I have a sneeking feeling that this sport involves more beer than normal fishing.
I've done it a few times with my buddies on the Potomac River. It's pretty fun and it will take you a while to get the hang of it because the water distorts the fish. You can go out and buy a reel that hooks onto your reel.
I will say one thing, it isn't as fun as river hunting!
