Sprinkle fish with salt; place in a heavy-duty zip-top plastic bag. Add hot sauce; seal and chill 2 hours, turning occasionally.
Remove fish from marinade; dredge in cornmeal. Place fish on a baking sheet coated with cooking spray.
Bake at 425° for 10 minutes or until fish flakes with a fork. Broil 3 inches from heat (with electric oven door partially open) 4 minutes or until lightly browned. Serve with Tartar Sauce.
