Hopefully they are just behind schedule, and not depleted.

Hopefully they are just late returning and not just gone.

The whole pacific off the west coast has been in turmoil this year. Massive die offs of birds, starfish, seals, and whales and other mammals. And the recent runs of millions of red crabs trying to escape the pacific.

Alaska has had air temperatures of over 20 degrees over normal, melting permafrost, and record wildfires across the state this month. Without the fishing industry they will take another big economic hit.

There is a large "blob" of unusually warm water off Alaska they have been worrying about moving north and adding to the sea ice melt. This unusually warm water off the coast has also contributed to a widespread red tide poisonous algae bloom. And the warm water has much lower oxygen levels than cold water, which is why the normally cold north pacific waters normally have so many fish. I am sure adding Fukishima radiation releases into the pacific are not helping either.
