Horse feathers: there are and have been farming fish in locations all around the world.  I was recently in Iceland and saw how they are growing the farming into a world market. Alaskan fisherman are simply wanting to keep the current system of fishing in place as the rest of the world grows this industry.  
There will be a place for traditionally caught wild fish in the market. But that is not a growing market as the availability of farmed fish from around the world is getting it share of a market that can not sustain the prices Alaskan salmon now demand.  At $ 12 to $ 15 a pound for red salmon in the fish markets,  the world market  will go elsewhere for lower prices as farmed fishing grows. Yes there will be a select part of the population who will want the fresh wild Alaska salmon. Every salmon caught is not a Copper River or Bristol Bay red. 
Thirty years ago there was the attitude that frozen salmon would never replace canned salmon.  That proved to be yet another fishing myth.
