In another shallow bowl, whisk together the salt and remaining flour. Slowly mix in the beer (batter will still have lumps).
Heat oil to a depth of 3/4" in a skillet to approximately 350F.
Coat the fish in the flour, shaking off the excess, then dip in the beer batter and add to hot oil.
Cook the fish until golden brown, turning as necessary. Serve immediately./
