In a large stockpot, bring first 10 ingredients to a boil. Reduce heat to a brisk simmer and continue to cook, skimming the tomato foam from the top of the stock.
While the stock is simmering, make a dark roux using the cottonseed oil and flour. To the roux, add the okra, stirring constantly. Once the okra is incorporated into the roux, add the onion, celery, green onion, bell pepper, parsley, garlic, Creole Seasoning, and Cayenne and Garlic Sauce, stirring well to incorporate. Cook until the vegetables become soft. Add the shrimp and continue stirring until shrimp turn pink. Add the oysters.
Turn up the heat on the simmering stock. Transfer the seafood-roux mixture to the hot stock and stir vigorously until the roux is completely dissolved. Bring the stock to a boil once more and then reduce to a simmer. Add the crabmeat.
Remove the gumbo crabs and serve over rice.
