Increase heat to medium and gradually whisk fish stock and milk. Bring to a simmer over medium heat. Cook and stir until the mixture is thick and smooth, about 10 minutes. Stir in 1/2 of the Cheddar cheese, nutmeg, and pepper. Remove from the heat.
• Layer 1/2 of the potatoes, 1/2 of the onion, and 1/2 of the spinach in the prepared casserole. Follow with white fish fillets and flaked salmon, then remaining onions, spinach, and potatoes. Pour all of the white sauce over top and sprinkle with Parmesan and remaining Cheddar.
