When I fish on the shore of lake when camping I bring a stringer, stake it by the edge of the water, put a link in mouth and out in front of gills so they can swim to get oxygen. If they stay alive until I am ready to walk back to camp, I whack them.

I never had you figured for a guy who believes in torturing small helpless creatures.
