I know there is a lot of confusion about mercury in fish as well as the difference between farmed salmon and wild salmon.
For information about mercury, the EPA has a website with good information:

If you want to make seafood choices that are environmentally responsible as well as know potential health dangers, I would recommend looking over Seafood watch provided by the Monterey Bay Aquarium:

If you want to know about Salmon specifically, I recommend reading over the Salmon page provided by Seafood Watch:

Would you know if Copper River salmon is really better than other types? There seems to be a lot of hype surrounding it, and it's expensive. I don't mind paying more for special foods, as long as it's worth it. Have you tried it?
