John hi. I've never shipped salmon but it's done all the time by markets and such. There are shops in the malls that handle shipping of northwest products. They may be of some help. I do get smoked fish from my Norwegian inlaws occassionally. They have lots of contacts in the deepwater industries. Go figure. They usually smoke the fish and then vacume seal, and freeze it. Keeps well that way, sometimes for months. Hope this helps. You catching that much salmon on a fly rod?
