Ya knoW, I was just gonna leave it at the smart alleck comment, but I'm baffled by the OP and the attitude of some of you OAF'ers..
If you truly respected the fish with the type of reverence you mention, why do you fish in the first place? You dangle a fake piece of food in front of them, drag them forcibly from their homes into a world that immediately begins to kill them, you'd think the least you could do is put the danged thing out of it's misery! But no, you torture it and then put it back.. Why? SO THAT HOPEFULLY SOMEONE ELSE CAN TORTURE IT TOO!
The fisherman spends hundreds on gear, thousands on the boat, hours tying a fly or crafting a popper, years honing his skills with the equipment, countless time contemplating the eventuality of catching that monster fish.. And when it happens he's supposed to smile quietly and either quickly put it back (making sure to not touch it or bump it against anything), or quietly and respectfully say a prayer and slice it's throat?
I don't think I'll be posting any more fishing reports here, I obviously don't respect the fish enough..
