dc.description.abstractThe total length distribution of pink cuskeel Genypterus blacodes catches is difficult to obtain. On the contrary, it is easy to have access to the head length distribution. So, the purpose of this study was to obtain a relationship between a certain head measurement and total length to estimate the length distribution of the catches. Individuals were obtained from bottom-trawl surveys between 39°-47°S and the San Jorge Gulf of the Argentine sea. Sets of measurements of total length (LT), maxillar length (Lmax), head length (Lc),orbital length (Lo), preorbital length (Lpo) and head length-total length ratio (r=Lc/LT) by sex were obtained. The total length was estimated with a regression model using the head length as independent variable. No significant differences between males and females were found. The combined relationship was LT= 0.737638+ Lc 4.632991. With this relationship, the length distribution of catches of each area, of total area and of other cruises were estimated. For a length range distribution of 4 cm, the coincidence percentage between the observed and estimated length distribution was higher than 87. in all areas. The head length increased with size while the head length-total length ratio was around 20 for both sexes.en
