Abstract
In the present study, a generalized linear model (GLM), assuming a Tweedie distribution and log as link function, was used to generate a standardized catch per unit effort (CPUE) series for the sailfish caught by sport fishing boats based in São Paulo, Rio de Janeiro, Espírito Santo and Bahia States, from 1996 to 2014. The response variable was the number of sailfish caught per number of boats registered in the tournament per day. The following factors were tested in the analyses: "year" "month" and "local" representing the main effects of the explanatory variables. The overall pattern of the standardized catch rate indicates a relatively stable trend with a slight decline in the recent years, from 2009 to 2014.
