A year or 2 ago in the Oregon legislature, the tribes joined with the republicans to try and stop fin clipping in Oregon as an "unnecessary state expense" since we have lots of returning fish (now) and there's (in their eyes) little difference between wild and hatchery fish. The republicans wanted to make it difficult to distinguish between wild and hatchery fish so that ESA regs would be harder to administer with a less clear picture of declining wild fish runs. The tribes wanted more ability to net without conserns over wild fish, thus increasing their take. ie. If you can't tell the difference between wild and hatchery fish, who's gonna get upset over increasing tribal catch and rolling back wild fish protections, so long as the total number of returning fish is good? I don't believe the tribes or republican legislators give a dam about wild fish.
The legislation I believe was tabled due to a threatened veto from Gov. Kitzhaber.
