The Chinook Salmon have collapsed like 99%. We are talking the endangered species act should of kicked in by now. In my last Fukushima rant when we rolled over day 3000 I shared the numbers thanks to Kevin.

The best thing you can do is talk to local fishermen. See if they will talk to you on camera asking them about the fish. I know all commercial fishing in Oregon and Washington has been shut down as a result of this catastrophe. I don't know about Alaska. Next time you see a dead whale take a big knife and carve the words "Fukushima did this to me" in big letters on its hide. I know it sounds gruesome and I wouldn't expect you to do that but if I was in Alaska and I saw one I would. Other activists have done this in the past to try to expose Fukushima.
