Place the fish in a non-reactive casserole.
In a small bowl, combine the lemon juice, garlic, 1/2 cup oil, bay leaves and teaspoon pepper and whisk to emulsify. Pour the marinade over the fish and refrigerate 2 hours, turning fish once.
Preheat the oven to 400 degrees F.
Brush 4 full sheets of parchment paper with 1 tablespoon each of the remaining olive oil. Remove the fish from the marinade and place 1 in the center of each piece of paper. Season with salt and pepper and sprinkle with some of the olives. Wrap the fish in the paper and seal the edges. Place each package on a sheet tray and bake in the oven for about 10 minutes. Serve immediately.
