BTW, most "Atlantic" salmon is farmed, not wild. There is wild Atlantic stuff, but you're probably not getting it unless the sign in the seafood department specifically says so. I've never seen it for sale myself, personally. I've heard on TV it's almost fished-out of the Atlantic too. Per Wikipedia, the amount of farmed vs. wild Atlantic salmon produced was 1,433,708 tons vs. 2,989 tons in 2007, respectively.
"Alaskan" salmon tends to be wild-caught. It's also usually more expensive (on the East Coast), and harder to find (Whole Foods is usually you're best bet). Typically, "wild" is better for you than "farmed" salmon:
It has better nutritional value, including better Omega 3 to Omega 6 fat ratio, higher protein and lower fat quantity, and is usually lower in PCB's. If it's not marked as "Alaskan" or "wild", it's probably farm raised.
