Hi Issac....
I would not recommend using salmon Bones for stock,To oily.. When making any fish fumet use the frames from white fish and besure to remove the gills and blood line and rinse well in cold water and only simmer for 25 minutes and start only with cold water.After you fillet your salmon the meat that is on the frame can be scraped with a spoon and used for terrines;quenells,raviolis etc.The skin is great if you make sure it is well scaled,brush with vegetable oil,season with kosher salt and pepper and slow roast it until it is nice and crisp. You can cut into triangles etc and place as a garnish with your salmon entree,maybe as a top layer of a grilled salmon nepolian,or standing up in a dollop of leek/potao purre with your salmon. do a seared salmon caeser with diced crisp skin instead of croutons. Use your imagination
