A major point that needs both litigation and gonads is AK and BC.

When the US/Canada Pacific Salmon Treaty was first being debated, the WA Tribes had a lawsuit threatening, the "All Citizens" which was to establish that the Indian share was 50% of all US harvestable. AK was refusing to agree (remember that the treaty needs US Senate approval). Bill Wilkerson developed the current Co-Management framework to get the Tribes to at least not file the suit. That is still out there. Maybe it needs refiling.

There are international laws about trafficking in Endangered Species (CITIES). This could be applied to salmon but it would be difficult to pass the red-faced test of hammering Canada for harvesting WA's ESA listed fish while AK goes on its merry way.

Perhaps recovery of our fish is just too damn inconvenient. We'll nibble around the edges, taking fish from the politically weak (NI commercial and sports fishermen), loggers, farmers, and others who don't get organized.
