【 摘 要 】

From abstract: This paper presents corrected catch histories, standardized catch rates, and evaluations of the accuracy of federally mandated commercial logbooks for billfishes taken as incidental catch by the Hawaii-based longline fishery. The study was conducted because billfish misidentifications in logbooks caused by similarities in body size, shape, and coloration have long represented a major challenge in monitoring this fishery.
