Preheat oven to 400°.
Combine first 3 ingredients, stirring with a whisk. Place salmon on rack of a broiler pan lined with foil; sprinkle fish evenly with salt. Spread half of marmalade mixture over fish. Bake at 400° for 18 minutes or until fish flakes easily when tested with a fork. Remove from oven. Spread remaining marmalade mixture evenly over fish.
Broil fish 3 minutes or until topping browns.
