In a large mixing bowl, combine flour and cornmeal.
Add the flaked salmon, chopped bell pepper, diced onion, Worcestershire sauce, seasoned salt, black pepper, garlic powder, mayonnaise, and beaten egg to the bowl. Stir until the mixture is well combined.
Form the mixture into 6-8 patties, depending on your preferred size.
Heat a generous amount of vegetable oil in a large skillet over medium-high heat.
Once the oil is hot, fry the patties for 2-3 minutes on each side or until they are golden brown and crispy.
Serve the salmon croquettes hot, accompanied by your favorite dipping sauce or a fresh salad.
