Answer:
Catch and release makes sense for both the fly fisher and the fish. The angler will hook more fish using the C & R method and will land just as many if he learns to keep the line tight and properly "play the fish". The fish is released with minimal harm to its mouth as the barbless hook is much easier to remove. I personally like this method, because it requires less pain for animals, and it also leaves less of the chance of leaving behind plastic of fishing waste that could be harmful to the water. :)
