Resumo: 	The reading of otoliths sagittae collected during the INIDEP (National Institute for Fisheries Research and Development, Argentina) assessment cruises carried out in the 1993-2003 period allowed to estimate length and weight growth parameters and the condition factor of hake (Merluccius hubbsi) and to prospect the two management units of the species north and south of 41ºS (Argentine Sea, SW Atlantic). A great variability in total length and weight in each age group was observed; nevertheless, stable mean length and weight values per age group were observed in the period analyzed. Besides, the values estimated to determine possible growth variations in each and between both management units north and south of 41ºS were compared. The comparison of growth curves of males and females in each area showed highly significant differences. When each sex between stocks was compared, some years those differences were observed for growth as a whole and only for some parameters in others.
