5. Over medium heat, warm the oil in a large Dutch oven. 
6. Add the flour, whisking constantly, until smooth and lightly browned, about 1 minute. 
7. Add the onion, bell pepper, celery, and garlic. 
8. Cook, stirring often and scraping the bottom of the Dutch oven to prevent scorching, until softened, about 8 to 10 minutes.

10. Bring to a simmer over medium-high heat.

13. Cover and cook until the fish and shrimp are cooked through, about 5 to 8 minutes. 
14. Remove and discard the bay leaves; season with salt and pepper.
