GATICA, Claudio  y  HERNANDEZ, Aldo. Standardized catch rate as index of relative abundance in fisheries: approach to Generalized Lineal Models. Investig. mar. [online]. 2003, vol.31, n.2, pp. 107-115. ISSN 0717-7178.  doi: 10.4067/S0717-71782003000200011.

The basic suppositions associated to the use of capture rates standardized as index of relative abundance in fisheries were revised, being discussed the advantages of the Generalized Lineal Models (MLG) as tool of standardization, considering the variations in the efficiency of the vessels as the product of the incorporation of new technologies and/or changes in the composition of the fleet. The validity of the capture for unit of effort (CPUE) as index of relative abundance in multispecies fisheries and highly migratory species was analyzed; together with their utility like auxiliary information in the calibration of age-structured models
