Resumo: | To determine the existence of different population units of longtail hake (Macruronus magellanicus) of the Argentine Sea, the meristic and morphometric characters of 861 specimens from two different areas were studied measuring 24 body distances with the landmark methods. Besides, the relation among weight, width and thickness of 806 pairs of sagittae otoliths as a function of length and sex of individuals was analyzed. Using the General Linear Model, the Principal Component Analysis and the Multivariate Analysis of Variance the fitted morphometric variables, the meristic characters and their relation to the Area and Sex factors were assessed. The variability observed does not show any conclusive evidence about the existence of more than one stock in the Southwest Atlantic Ocean.
