I'm not sure I agree that the Tribes going in early can honestly be compared to anything resembling selective fishing. When you string gillnets across rivers, your intent to target one stock over another doesn't make you selective; it makes you irresponsible, especially when whatever incidental catches you do get will be from endangered stocks (and dead, which means you have failed in being selective).

Not implying C&R doesn't come with casualties, but at least the intent is genuinely selective, and for the most part, the practice is very effective.
