In a shallow bowl, combine the cheese, cracker crumbs, cornmeal, garlic salt, creole seasoning and pepper. In another bowl, beat eggs and beer, dip fish in the egg/beer mixture, then gently roll in the crumb mixture.
In a cast iron skillet, heat oil. Fry fish in hot oil for 5 to 7 minutes or until fish flakes easily with a fork. Drain fish on paper towels.
Notes
*Note: You can substitute; catfish, walleye, bluegill, crappie, or lake trout for the perch.
