Update the standardized catch rates of sailfish (Istiophorus albicans) caught as bycatch of the Spanish surface longline fishery targeting swordfish (Xiphias gladius) in the Atlantic Ocean

[EN] Standardized catch rates of sailfish (Istiophorus albicans) were obtained from 14,473 trip observations of surface longline fishing targeting swordfish during the period 2001-2019. The nominal effort modelled represented 80.65% of the total effort developed by this fleet during that period. In...

The nominal effort modelled represented 80.65% of the total effort developed by this fleet during that period. In roughly 28% of these trips at least one individual belonging to this species was found. Because of the low prevalence of this species in this fishery, the standardized CPUE was developed using a Generalized Linear Mixed Model assuming a delta-lognormal error distribution. The results indicate that the overall trend of the standardized CPUE was similar for the Atlantic Ocean and for the East and West stocks. The results showed an increasing trend for the Atlantic Ocean and for the East and West stock reaching a peak in 2015 or 2013, followed by a decreasing trend in the recent years analyzed, although the values remained higher than at the beginning of the series.[FR] Des taux de capture standardisés du voilier (Istiophorus albicans) ont été obtenus de 14.473 observations de sorties en mer de pêcheries palangrières de surface ciblant l’espadon au cours de la période 2001-2019. L’effort nominal modélisé représentait 80,65% de l’effort total exercé par cette flottille pendant cette période. Dans près de 28% de ces sorties en mer, au moins un spécimen appartenant à cette espèce a été rencontré. En raison de la faible prépondérance de cette espèce dans cette pêcherie, la CPUE standardisée a été développée à l’aide d’un modèle mixte linéaire généralisé en supposant une distribution d’erreur delta-lognormale. Les résultats indiquent que la tendance globale de la CPUE standardisée était similaire pour l’océan Atlantique et pour les stocks de l’Est et de l’Ouest. Les résultats indiquaient une tendance à la hausse pour l’océan Atlantique et pour les stocks de l’Est et de l’Ouest, atteignant un maximum en 2015 ou 2013, suivie d’une tendance à la baisse au cours des années récentes analysées même si les valeurs restaient supérieures à celles du début de la série[ES] Tasas de capturas estandarizadas del pez vela (Istiophorus albicans) fueron obtenidas a partir de 14.473 mareas de palangreros de superficie dirigidos al pez espada, observadas entre los años 2001 y 2019. El esfuerzo nominal modelado representó el 80.65% del esfuerzo total desarrollado por esta flota durante ese periodo. En el 28% de las mareas hubo presencia en sus capturas de al menos un individuo de esta especie. Debido a la baja prevalencia de esta especie en esta pesquería, la estandarización de la CPUE fue realizada mediante un modelo del tipo Modelo Lineal Mixto Generalizado asumiendo una distribución de error “deltalognormal”. Los resultados sugieren una tendencia general de la CPUE estandarizada similar para las áreas del Atlántico total y para los stocks Este y Oeste. Los resultados muestran una tendencia creciente alcanzando picos sobre 2015 o 2013 seguida de una tendencia decreciente en los años recientes del análisis, aunque permaneciendo valores más altos que al inicio de la serie.Peer reviewedInternational Commission for the Conservation of Atlantic TunasConsejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202420242023info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/350484reponame:DIGITAL.CSIC.
