Mining has done nothing to salmon fisheries.  OTOH, if you really want to save the fish, do something about commercial fishermen in Cook Inlet.  Silver fishermen in the MatSu, Anchorage and Turnagain Arm are all seeing few silvers due to the 100,000+ caught so far by commfish.  Far easier to rail against mining and hydroelectric power than to go after those who are actually doing the damage to the resource.  Cheers -
