Thaw the fish in the refrigerator. Preheat the oven to 350°. Cut the fish into four pieces and place in a 9 by 13 baking pan. Combine paprika, garlic and onion powder, pepper, oregano and thyme in a small bowl. Sprinkle spice mixture and lemon juice over the fish. Drizzle melted butter or margarine on top. Bake until fish flakes easily with a fork, which takes about 25 to 30 minutes.
