Yeah, I knew that even as I was posting that you'd say that. But as I already stated, I posted it to provide a historical perspective and to establish that illegal fishing for salmon has indeed been a "trend," as you called it previously, for a number of decades. It hasn't stopped, although evidence suggests that China's emerging aquaculture industry may prove to be a more lucrative and less dangerous option, resulting in a decrease in IUU activity.
I don't believe I claimed that most "American salmon spend time in the Sea of Japan," that's just not how salmon migration works, but at least one of the king runs in the Yukon-Kuskokwim Delta spent their ocean phase in that region, and illegal/overfishing in the Sea of Japan pretty much decimated it. It was simply an example. Multiply that by a thousand or more other areas where "our" salmon are spending their ocean phase and the preponderance of illegal fishing in these areas, and you've got a lot of smoke.
It's really easy to find where I'm getting my numbers from via Google, by the way. Most of the vessels turned and ran, and a few refused to allow boarding, but I'm sure everything was on the up and up, right? The listed violations included shark fins, but they didn't list all of the violations, and who knows what were on the others that ran away or refused to allow officials to board. But the thing is, when you're bottom trawling with 5+ mile nets in the North Pacific, you're going to bring up salmon; there's just no way not to.
And oh look, another unfortunate "one-off." Must have been a silly misunderstanding, right? You do realize that for every one of these that are caught, numerous others very likely exist undetected?

Probably not a good idea, though, to think that just because something is tough to find on Google means it doesn't exist, especially where international matters involving remote parts of the planet are concerned. Most of this activity isn't even caught (the usual strategy is to turn off the vessel's transponders to avoid detection, and although satellite surveillance can still catch some of it, it's pretty much a needle-in-a-haystack scenario), and enforcement is typically left to the flag country per international law. You're not going to find much on Google out of China; they've even got their own maritime enforcement ships cruising the North Pacific, but their IUU prosecutions don't make it to Google. Nonetheless, wild salmon is among the
Again, my point remains that whatever's diminishing the king salmon stocks is happening before the fish even reach Alaska waters, and that something is happening in the areas where they live out their ocean stage. All salmon species spend this stage in deep waters, but king salmon go deeper than others, which raises questions about the ocean acidification theory at this point in time, at least. As the oceans continue to heat up, who knows.
But if you want to believe that although China is pillaging the planet's seas, including the North Pacific, they're somehow leaving the salmon in international waters alone, be my guest. But that's not how these mega-trawlers work.
