Preheat the oven to 375 degrees F. If using whole fish
, fillet each fish and cut the skin from the fillets. Place the fillets in a bowl of cold, salted water for 10 minutes. Pat the fillets dry. Put the potato chips on a large plate. Dip each fillet into the melted butter and then roll the filets in the crushed potato chips
to coat. Lay the fillets on a foil-lined baking pan and sprinkle with the cayenne and lemon pepper. Bake until golden brown, 8 to 10 minutes.
