Preheat oven to 400°. Spread salmon with hoisin sauce; sprinkle with pepper. Place on a greased foil-lined baking sheet, skin side down. Bake 12-15 minutes or until fish begins to flake easily with a fork.
Meanwhile, in a small saucepan, combine pineapple and marmalade. Bring to a boil, stirring occasionally; cook and stir 4-6 minutes or until slightly thickened. Spoon over salmon; sprinkle with cilantro.
