It happens to me on occasion, with dries, streamers, and nymphs. Someone made the observation about glo bugs earlier this season, so I started paying attention, and since then, I have not had a deep hooking with a glo bug, in a couple hundred fish. Moving water, however.

This IS a blood sport. You will kill fish, as long as you are having fish eat your fly. The only way to avoid completely the possibility of accidental kill is to not fish.
