You might have heard to eat Wild Alaskan Salmon. You might still wonder why Farm raised is so much cheaper. This article goes into great detail of the differences. I recently have found a source of buying Wild Alaskan Salmon as a buying club at wholesale prices. If you are in Austin and want some Wild Alaskan Salmon for $13 per lb, let me know! Otherwise you can join as a buyers club yourself.
