I C&R for the most part, but once in awhile when I haven't eaten fish for awhile I may keep the last one I catch that particuler day. (do to water pollution in fresh and salt water I try to only eat fish about a half dozen times a year, with fresh water only about twice) The only other time I will keep a fish is if I screw up and fight the fish to hard and it won't fully revive when I try to release it.
