Personally I think the rule that says you can cull fish as long as the one you release is alive and healthy is a subjective term.

Once they have been fought and released is one thing, but they still have a build up of lactic acid. If they are in a live-well banging around for a while or have their lower jar pierced and them tore to the jawbone by a stringer followed by being caught.. Its pretty sketchy in my own ethical view. Ones persons alive and healthy VS someone else's is the subjective component of this condition.

I personally can't do that, but the law is the law.
