Add the flour and reduce the heat to low and cook for about 3 minutes, stirring often.
Add the vegetable broth; increase the heat to high and bring to a boil.
Add the seafood, fish, corn, and all the seasonings (garlic salt, black pepper, curry powder, cumin, celery salt, cayenne pepper, ground ginger, and ground coriander seed).
Reduce heat to low and simmer uncovered for about 10 minutes, until the seafood and fish is just cooked.
