The purpose of a hatchery, as I understand it, is to serve a number of functions. Among them is enhancing stocks, certainly, but it's also in order to provide opportunities for harvest. That's the whole idea of Robertson Creek Hatchery, and on and on it goes.
The idea is that you're serving a number of different functions, depending on what system you're dealing with. Again, if you turn towards 100% marking, that marking provides some excellent opportunities to enhance systems that currently don't have any kind of enhancement and may desperately need it, and that do not mark those fish. They are treated in all circumstances as wild fish.
