Combine celery salt, dry mustard, pepper, paprika, nutmeg and ginger. Toss tater tots with seasoning to coat and bake according to package directions.
Meanwhile, in a shallow bowl, mix together cornmeal, flour, salt, paprika and cayenne. Heat oil in a large sauté pan over medium high heat. Have a sheet pan or plate lined with paper towels ready for draining. Dredge several strips of fish in the cornmeal mixture and carefully place in hot oil. Fry for 5 to 8 minutes total depending on thickness of fish, turning often, until golden and crispy. Transfer to paper towel lined pan and continue to dredge and fry remaining fish in batches.
