Nuevos antecedentes de Pseudocarcharias kamoharai (Matsubara, 1936) (Chondrichthyes: Lamniformes: Pseudocarchariidae), frente al norte de Chile

Abstract: La pesquería del pez espada (Xiphias gladius Linnaeus, 1758) ha permitido tener acceso a una ictiofauna oceánica pelágica que en muchos casos es altamente migratoria. Estos peces son capturados como fauna concurrente y/o asociada a la mencionada pesquería, la cual ha sido escasamente estudiada y no se tiene real certeza de su composición taxonómica (Acuña et al. 2002). De ellos, se debe considerar el importante aporte de los peces condrictios, los cuales, según Acuña et al. (2002), alcanzan al 72% de la captur… Show more

“…Even though P. kamoharai is globally widespread, it is reported to have a patchy distribution in most areas of occurrence (Béarez et al , 2001; Stewart, 2001; Meléndez et al , 2006). The first records for the Atlantic Ocean came from the eastern Atlantic (Cadenat, 1963), and since then the species has been regularly recorded as by‐catch of commercial pelagic longliners operating along Brazilian oceanic waters, being particularly abundant in the tropical western Atlantic (north‐eastern Brazil) (Hazin et al , 1990).…”

“…paucus and P . kamoharai are incorporated as new records, and are by‐catch in the pelagic longline fishery targeting swordfish and tunas (Meléndez et al ., ; Bustamante et al ., ). Unconfirmed species are present in all zones and generally reflect low human population density and limited commercial fishing activity in coastal regions such as the oceanic islands and austral south zones, which limit accessibility and specimen collection.…”

“…Given that E. brachyurus, E. lucifer and E. unicolor are noted for having a restricted distribution in the north-west Pacific Ocean, these rare-occurrence species could be the result of misidentification of currently undescribed species in the Chilean oceanic Island region (Ebert et al, 2011;Straube et al, 2011). Species such as I. paucus and P. kamoharai are incorporated as new records, and are by-catch in the pelagic longline fishery targeting swordfish and tunas (Meléndez et al, 2006;Bustamante et al, 2009). Unconfirmed species are present in all zones and generally reflect low human population density and limited commercial fishing activity in coastal regions such as the oceanic islands and austral south zones, which limit accessibility and specimen collection.…”

“…Como consecuencia de los nuevos registros de los taxa capturados en aguas chilenas se observó un aumento de 48 a 56 en el número de especies, sumando una familia previamente no registrada: Pseudocarcharhiniidae (Lamniformes) (Rubio et al 2005, Meléndez et al 2006, Reyes & Hüne 2006. Al respecto, cabe señalar la confirmación de la presencia de Isurus paucus en la zona centro de Chile, captura efectuada el 2004 en Caldera y Paico, y cuya presencia fue también registrada en marzo del año 2007 en el Pacífico suroeste (32º30'S, 74º30'W) en Caleta Portales, Valparaíso (Bustamante et al 2009), que junto con Sphyrna lewini (conocida en el Perú) no han sido confirmados en los registros de pesquerías artesanales e industrial, aumentando el rango de distribución de ambas especies (Sebastian et al 2008).…”

“…A nivel de Familia, se adiciona la familia Pseudocarchariidae al orden Lamniformes, con una sola especie, Pseudocarcharias kamoharai (Matsubara, 1936), representada por un ejemplar capturado en la costa norte de Chile (Meléndez et al 2006). Esto permite documentar la presencia de un nuevo taxón para aguas chilenas y geográficamente, indica la amplia distribución austral de esta especie en el Pacífico suroriental.…”
