Artisanal fishery landings of large pelagic fishes and sharks in the Ecuadorian coast during 2008Abstract
Se presentan los resultados del seguimiento de los desembarques de peces pelágicos grandes y tiburones procedentes de la pesca artesanal durante el 2008. Se determinó un total desembarcado de 32 150.37 t, que correspondió 67.4 % y 20.2% a peces pelágicos grandes y tiburones respectivamente. Entre los pelágicos grandes la familia Coryphaenidae fue la más representativa, en tanto que para el grupo de tiburones fue Alopiidae, y en menor presencia Carcharhinidae y Sphyrnidae. En los puertos de Manta, Anconcito y Santa Rosa se registraron los mayores desembarques de pelágicos grandes mayormente de la familia Coryphaenidae en tanto que para los tiburones los aportes más significativos están reportados para el puerto de Manta. Las capturas de dorado estuvieron principalmente sobre organismos entre 80 a 100 cm LT (62.5%). La distribución de frecuencia de tallas de tiburones presenta una marcada variabilidad en cada puerto y entre puertos.The results from the monitoring of large pelagic fishes and sharks landings during 2008 at the Ecuador continental coast are presented. A total landing of 32 150.37 t was estimated, corresponding to 67.4 and 20.2% of large pelagic fishes and sharks respectively. Coryphaenidae was the most representative in landings between large pelagic families, among sharks’ families; Alopiidae was the higher, and the minor contribution were Carcharhinidae and Sphyrnidae. Manta, Anconcito and Santa Rosa ports registered the higher large pelagic fishes landings, mainly Corypahenidae family, furthermore Manta Port contributed with the sharks landings significantly. Length frequency distribution showed organisms caught between 80 and 100 cm TL (62.5%). The length frequency distribution in sharks showed higher variability in ports and between ports.
