I eat it if I kill it. If it is under/over legal size i take a picture and put it back in the water. Personaly illd rather have the big red than the koi(you have a 50# koi? that impressive), especialy since he took 45+minutes of hard fighting to catch, and man he tasted good(when the hurricane hit it ruined alot of the fish i had in the freezer, i was PISSED cause i had four reds we were going to BBQ in there about two weeks later). I do beleive VERY strongly in practicing legal fishing, and being ethical about how i handle fis. It keeps populations up and makes for better fisheries, aside form being the ethical thing to do. I was supised when i started kendo, becasue the movements ina men cut are nearly identical to those used when casting a surf rod, just softer(you push with your right hand to achieve a whip with a rod alot more than witha shinai)
