Feeding success during the early life stages of fish is one of the main factors that determines recruitment and stock fluctuations. In the Argentine Sea, the Patagonian stock of Merluccius hubbsi is the most impor-tant in biomass, spawning from December to April in the north Patagonian shelf region (43?45º30?).Since previous knowledge about larval feeding of the species in this region is fragmentary, adequateinformation is required for a complete assessment of its importance in the food web and its effect upon recruitment. Our primary objective was to examine the feeding strategy of M. hubbsi larvae in relationwith prey availability in the nursery ground. Feeding incidence was 87%; hake larvae consumed mainlycalanoid copepodites
