Strike zone,
Remember that C&R fishermen can be excellent enforcers of C&R regulations. The poachers who are a real problem are those who can sneak down to where no one will see them, where a warden is unlikely to nab them. For example, in my opinion, the loss of the C&R season in the Puget Sound rivers will actually hurt steelhead more than it helps them, precisely because these cunning poachers won't have C&R fishermen to watch for. This is of course a theory, but I believe there is logic behind it. I've heard it spread around before.
