captura por unidade de esforço (CPUE), peixes de bico, modelo linear generalizado, distribuição de tweedieResumo
No presente trabalho, um modelo linear generalizado (GLM) assumindo a distribuição de tweedie e função link log, foi utilizado para gerar uma série de captura por unidade de esforço (CPUE) para o agulhão-vela capturado pela pesca esportiva baseada nos estados de São Paulo, Rio de Janeiro, Espirito Santo e Bahia de 1996 a 2014. A variável resposta foi o número de agulhões-vela capturados pelo número de embarcações registradas por dia de torneio. Os seguintes fatores foram testados: "ano" "mês" e "local" representando as principais variáveis explicativas do modelo. O padrão geral da série de CPUE padronizada indica uma tendência relativamente estável com um leve declínio nos anos recentes entre 2009 e 2014.
