Southwestern Roast Salmon with Spicy Avocado-Mango Salsa

I can't wait to try this with fresh caught wild salmon. Won't be for a while though. I was able to buy a fairly fresh 5 pound whole salmon (sorry but I don't know if it was wild or farm grown). This is my version of roast salmon with avocado mango salsa, which it much spicier than other mango-avocado salsa recipes I've tried. I served it with roasted root vegetables, a spinach leaf salad with a citrus Vinaigrette dressing, and some fresh baked homemade sourdough biscuits with honey butter.
