Preheat oven to 350F.
Wash the fish under the cold water and pat with the paper towels. Rub the fish lightly with the oil and sprinkle with 1/2 tsp salt and 1/8 tsp pepper on both the inside and outside.
Now it is time to make the stuffing. Place the butter in the skillet and saute' the celery, onion, and the green pepper until the onion becomes soft. Then add the tomato, parsley, and bread crumbs. Season this mixture with a dash of pepper, and the salt. Now spoon the stuffing into the cavity, and close the opening with the wooden picks or skewers.
Place the fish into a greased, shallow roasting pan. Alternating the slices, arrange while slightly overlapping the slices of lemons and limes over the top of the fish, and sprinkle with lime juice.
Cover the fish with foil and bake for about 45 minutes, or until the fish flakes easily when tested with a fork.
With a large spatula, really carefully lift the fish to a heated platter. Garnish with the parsley.
