It is still legal to snag salmon in some places here in MT, in fact, snagging season just opened yesterday. Most folks I know of, can all they snag, and dont bother to prepare any other way. It don't matter if they get a little mushy, 'cause you are just treating them like any other canned fish, sandwiches, crackers, etc.
Just a few days ago, I caught several hook jawed males that were a little grey, and they were still firm and did just fine in the smoker101eatdrink101
