Last browny I shot, I was determined to be "ethical" and salvage meat with the hide and skull. First cut I made nicked the gut and a ball of tapeworms the size of a softball came rolling out at my feet.
I'll hang the salmon that have a few in the gut cavity; many do. But the ones which have tapeworms in their flesh, usually along with a pus-y pocket accompanying, get a fee pass to starfish heaven.
