When it comes to fishing except with some nedangered spiecies every state is responsible for it's own regulation/enforcement. Due to that the states are left to set and collect their own fees as they see fit. That is why the licences and stamps are not transferrable. But you need to check local regulation since on a lot of boundry waters you do not need additional licence. As to national catch and release licence - argument could be made that since not all relesed fish will survive those who practice C&R are still using some resourcec from the state they fish in. Then of course all of the states would start squabbling as who is gettin how much from the collected money... I think Status Quo is the best solution even though it can get quite expensive for the people that fish in numerous states.
On the other hand if you consider fishing laws and regulations in most of Europe fishing here is really cheap.
