I've been a disciple of catch and release since I've become a fly fisher, partly because the sport of fly fishing is so elegant the kill is a minor component and easy to forgo and I don't need to kill for sustenance. If I feel like eating fish it is just as easy to purchase one in the market as it is to bop one on the head streamside. And maybe it helps to salve the guilt I still feel when I think of all the fish I left suffocating on the bank as a young boy with no intention of keeping them.
