any rule changes that may happen have to be ones that "can be enforced".
For example... if they ban using treble hooks while trolling for salmon... thats easier to enforce, as when they board your boat and inpspect your salmon lures, it becomes clear to the naked eye if your in compliance.
A quit once you have netted 2 keepers... impossable to enforce! Most will never comply with that, it is too easy to lie. just human nature!
