On the boat WHILE you're fishing? I mean maybe you got into a great boil that lasts a couple of hours, and you don't want to miss any more catches, so you just put them in the live well. THEN when the catching is dead again, perhaps THEN you might want to to the killing and cleaning. Am I missing something? For the winter months here in Colorado, we'll mostly be trolling for wipers and such (hopefully we'll get lucky and NOT catch trout). So the killing as soon as possible I get, but it's the HOW that I'm asking about :duh: Maybe I just beat them to death like this poor guy...
