Every spring I order real wild Copper River salmon from Alaska. I get enough to last us all year and put it in my freezer. It's so much better than the farm raised salmon in the grocery store and fresher than the wild salmon they sell that's been sitting out, for who knows how long, defrosted in the fish case. Some of that stuff looks pretty sorry.
I order my salmon from this place and it comes on dry ice, each fillet individually vacuum sealed so you can take out from the freezer just how many pieces you need at a time.
These are absolutely gorgeous fish - so fresh and firm with bright silver skin. I order two kinds, the cheaper Sockeye salmon and a little of the more expensive King salmon. The King salmon fillets are thicker than the Sockeye and and are a little higher in fat, which contains all those great Omega-3 fats.
