I just smoked a batch of salmon, skin-on. When we eat some, some very happy dogs get the skin. I would be curious if there was a good prep for human consumption though.
I'm not usually a fan of the texture straight off the meat, but frying it up does sound good! And after all, this has been smoked already, so there's a ton of flavor.
Humans can eat it the same way. I just pan fry until it's crispy and add some salt to taste. My kids love fried salmon skin (along with salmon + rice + dry seaweed wrap).
