It seems like the Tribe isn't actively looking for the ventral clip. That explains a lot. But that isn't all that's missing if effective monitoring of the program were the goal. That the OPGA are tallying their catch of Snyder fish is good, but as far as it goes, it's in the category of anecdotal information, still falling short of monitoring for program effectiveness. I don't hear anything about how many of the Snyder fish are escaping to spawn naturally or what their geographic distribution is. And the follow up to that knowledge would be tissue sampling for genetic analysis and a comparison of spawning success. Then it wouldn't be necessary to refer to the Hood River studies.
