Resumen : The Spanish purse seine fleet operates in a wide area of the Indian Ocean since 1984. A logbooks system provides detailed information of catches (set by set) and effort. Together with this information, an intensive work of interview during 4 years (1994-1997) has provided technical equipment data. These data have been used to estimate standardized catch per unit effort (CPUE) indices of abundance for yellowfin from the Indian Ocean. Standardized catch rates have been estimated using the Generalized Linear Model (GLM) approach. The model proposed includes factors related with the stock abundance together with factors related with catchability changes.
