This picture reminds me of that Congressman that was on the News Hour a few times in the late 1990s. His last name was Salmon. The first time I saw him he talked about how working on (whatever the issue was) gave him that "salmon day feeling". You know, the kind where you swim upstream until you are practically dead from exaustion and then you get screwed. He retired after three terms because he had promised to when he first got elected. His reasoning was that he couldn't expect other people to keep their word if he didn't.
If you want more sustainable seafood, look for the Marine Stewardship Council label.
