Pressure, pressure on the department of fish and game applied by the tourist industry, by the residential fishermen, by the commercial guides association, all of these culminate in political pressure to keep things going as they have always ran.
Ard,The folks who talk to me about this situation seem to be so opposed to this thought that is is obvious. I don't preach it, I make mention that I think we may have over-killed but I don't enter into debates on the topic. I see this like a community with a limited aquifer to draw water from deciding that everyone is entitled to have a swimming pool only when the wells run dry they are desperately searching for someone other than the pool owners to blame for the dry wells.
I can't say that I have a solution, but let me point something out. What your writing makes obvious is that the parties involved are competing with each other, but they need to be collaborating. It's also obvious from what you say that whatever the solution is, it will require sacrifice, and on a mass, even global level.
We don't have that kind of culture, and that's where the problem lies. Our culture is driven by capitalism (emphasizing self-interest and immediate gain) and that produces the sort of politics you describe.
We need a cultural outlook that promotes bringing people together in a collaboration of willing sacrifice on a mass level, and that is a very tall order.
Christianity proposes just such a thing. It's universal in that every man, woman, and child, is important and matters and that all must contribute to the universal good. It makes sacrifice central--the sacrifice on the cross on Good Friday is paramount. As I will be telling a group of retreatants on Good Friday, the grain of wheat had to fall to the ground and die to bear fruit. Christianity says that spirit has to be replicated in an individual's own life for salvation.
Imagine if that spirit could be replicated again, again, and again across many people and places. It may just result in the kind and numbers of people who can come together in the sort of mass collaboration and sacrifice that will be necessary to save those precious salmon runs.
Without it, I don't think there's much hope at all. The solution has to overcome a natural inclination in us to be greedy, selfish, and exploitive.
Christianity contains within it that spirit, and especially its Catholic version. The Church is said to be Universal and, for believers, that mandates engaging in a universal effort for the good and love of others in absolutely every dimension of human life. Anything less is a failure in a Christian and a failure for humanity. Imagine if a spirit like that could be brought to bear on the problem of those salmon streams.
I don't think much else offers that kind of spirit. Marx proposed communism, but that's ultimately a system based on force, the results were horrifically bloody, and it became a system of haves vs. have-nots as well.
If you want to see it explained here's a link to Pope Francis's Laudato Si "A Care for our Common Home" http://www.vatican.va/content/franc...-francesco_20150524_enciclica-laudato-si.html
I can give you this much: I will use this example in my retreat talk this Friday. At the very least, a group of mostly college students will hear your story of the salmon and learn that fixing a problem like that is their duty, and they are called to develop in themselves the sense of self-sacrifice and service in themselves so they can do it.
