So people are allowed to fish and kill a lot of them and you guys are more limited on fire many you can fish to reproduce? Wow, I never cease to be surprised by how stupid government can be.
Past certain level of efficiency, there's likely something of the trade-off triangle ("good, fast, cheap, pick two"), and two of its vertices are "smart" and "democratic".
People are allowed to fish and kill more than protect and reproduce, because the "kill" side has a lot of people with money, who don't give a damn about ecology or even long-term viability of their businesses, whereas the "protect" side that does the reproduction is also the same people who set up limits on what to do with the fish, so they kind of obey their own rules.
Can you rephrase this in the form of a sentence?
If you really want to increase genetic diversity there is a really cheap and simple solution. Reduce recreational fishing.
Okay, ... and is this management working? can counteract the increase of predator pressure (normal predators plus new pirate fishing at sea)?
Then all is fine and we shouldn't be talking here about extinction levels, and caring about the future of the salmon, should we?
"The Council estimates that the true cost of bringing a single spawner back to that uppermost region is as much as $68,031"
Why are even recreative fishers still allowed to catch a 68000 dollars fish (paid with money from taxes) for..., how many?, a fourty dollar license?, 500 dollars in permits and hotel and you can take two or tree fishes? Is a stupid deal. Why they are allowed to destroy all this hard work that aim to return the population to sustainable levels?
If you are bored go play baseball, make photos from nature, or read a book. If you want to see fishes, go to an aquarium or see Sponge Bob on tv.
Either somebody will fix it, or somebody will eventually have a good time fishing the last one. In both cases problem solved.
