Abstract

Information from the logbooks of the longline fleet operating under Mexican flag from 1980 to 1990 was analyzed to determine the tendency of the catch per unit effort (CPUE) of the sailfish fishery. Multivariate analysis techniques (principal components analysis) were used to group the fishing units of this fleet. Time series methods were used to estimate the tendency of the CPUE as an abundance indicator, and this was compared to the behavior of the same index for sailfish sport fishing in Manzanillo, Colima, during this period. The results indicate that the resource is underutilized.
