In the meantime, cut your orange into ¼ inch slices.
Season the salmon with salt and pepper. Top with the orange slices. Flip your salmon onto your baking sheet so it is skin side up with the orange slices under the salmon. Trust me...this way all that delicious fat on the skin side runs into your salmon. Set aside until the oven is preheated.
Cook until desired doneness or until the salmon easily flakes and the white albumin starts to form on the top. This can take anywhere from 10-20 minutes depending on the thickness of the salmon. Because the copper river sockeye so dark in color, the color does not change as much as it does with regular salmon.
