People that pretend to not understand why anyone would go fishing if they don't intend to keep any, are irritating. If I kept every legal sized fish that I caught, and then immediately stopped fishing when I got a limit, then I wouldn't be fishing very often. A couple fish dinners per month is good but I don't want fish for dinner every single night....or even once every week, to be honest.
Just consider C&R as PRACTICE.
Successful Hunters practice at the range.
Gardeners practice too.
