I don't remember when I decided to try to catch a carp on a fly rod, but after many failures I started asking around about carp, to see how I could improve my chances. What I learned was that going after carp was a lot like fishing the flats for Bone fish, something I had not had the opportunity to do. I'm a bass, trout, crappie, walleye, etc man myself & had never needed to learn these kinds of techniques. (ever catch a walleye on a fly??)
There has been growing interest in recent years about catching carp on a fly & for good reason. It can be very fun & challenging. Plus, when you connect with even the smallest of carp, look out.
After many tries I finally hooked up with my first carp several years back. It was near dark on a late spring evening & even though it was a small one, you'd have thought I set a world record by my reaction. After trying & failing many times I was elated to catch my first (be it oh, so small) carp.
Here is a great article about fly fishing for carp. I discovered it on the Fishing For History blog - a great daily read I highly recommend you check out. The article focuses on the carp's great ability to hear, which is one of the first things you learn when trying to catch them. The slightest noise will spook them.
If you haven't given it a try, I think you should definitely try your hand at fly fishing for carp. If you live in an area where it's too hot this time of year for trout fishing & you want to go after something else besides bass or pan fish, give carp a try. Once you land your first one, you'll be hooked!!!
