Abstract: Based on the comparison between length composition of landings and that of research cruises, filtered by the selectivity of the mesh used by the commercial fleet, to rebuild length distribution of catches, an indirect quantitative method was developed and used to estimate, in weight and number, the individuals discarded by the commercial fleet south of 41° S. Discards ranged between 15,563 and 46,113 annual tons in the 1986-1993 period which represented 10-13% in weight and 28-32% in number of actual catches, composed of around 87% of individuals age group 1, 12% of age group 2 and the rest of individuals age groups 0 and 3.
