The present paper deals with the standing stock (Pw1) of the common hake (Merluccius hubbsi) and the austral hake (Merluccius polylepis), using the swept area method (Alverson, 1971) and with the Potential Yield (Cmax) using the Gulland (1970) method. The standing stock of the common hake was 2.642.715 tons. The highest concentrations of this species were distributed over 12.348 nm² (13% of the total distribution area) with 1.178.843 tons. This area was located between 41° and 45° of south latitude and between the coast and 100 m of bottom depth in the Patagonian Shelf. The other 1.463.872 tons were distributed over a wide area of 82.727 nm².
