Slightly different angle. I've never really thought about it but if I've reached a limit, isn't it still legal to fish as long as I do not keep any? That would be like a bass tourney when someone has their fish limit but is searching for a bigger fish?
In a tournament, usually they apply for a culling exemption. Otherwise once you decide to keep a fish, it counts for your limit. So in a tournament they can keep fishing an cull as needed. But other than that, if you have limit, You likely could be sited as you have your limit, once you pull that 1 over limit out of water, regardless of intention to immediate release, you are over your possession limit by definition.....cited for it? depends on CO.
