Última Patrones estacionales de abundancia en el Golfo Nuevo y migración a lo largo de la plataforma Argentina de cazones (Galeorhinus galeus ;Linnaeus;) y gatopardos (Notorynchus cepedianus ;Péron ;) (Argentina) Ecología austral Irigoyen,Alejo; Sibbald,Carolina; Cuestas,Mariano; Cristiani,Franco; Trobbiani,Gastón. Conocer los patrones de movimiento de una especie tiene implicancias sustanciales para su manejo y conservación, en particular en aquellas que realizan migraciones de gran escala. El objetivo de este trabajo fue estudiar los patrones estacionales de abundancia de cazones y gatopardos en el Golfo Nuevo, provincia de Chubut, y sus patrones migratorios a lo largo de la plataforma argentina, por medio de un plan de marcado y recaptura convencional. Se capturaron y marcaron un total de 13 gatopardos y 228 cazones a lo largo de un ciclo anual completo. A partir del análisis de datos de captura por unidad de esfuerzo (CPUE) se encontró que el cazón presentó un patrón estacional marcado, con una abundancia mayor desde mediados del verano y durante el otoño; la...

Ano: 2015 URL: http://www.scielo.org.ar/scielo.php?script=sci_arttext&pid=S1667-782X2015000200010 Large-scale migration of a school shark, Galeorhinus galeus , in the Southwestern Atlantic Neotropical Ichthyology Jaureguizar,Andrés J.; Argemi,Federico; Trobbiani,Gastón; Palma,Elbio D.; Irigoyen,Alejo J.. ABSTRACT Knowledge of the spatial and temporal distribution patterns of chondrichthyans is critical for their effective management. In this study we report and analyze a large-scale latitudinal migration (~ 1,425 km) of a female school shark in the Southwestern Atlantic shelf where it is currently classified as Critically Endangered. During the austral summer (February 15, 2015), ninety-four school sharks were captured (75 females and 19 males) and tagged with fin tags in Nuevo Gulf (~ 42°43’S, 64°53’W, Argentina). A female of 112 cm total length was recaptured in Uruguayan shelf waters in the austral winter (August 17, 2015). This long displacement represents the first direct evidence to support Vooren and Lucifora’s hypothesis of a single transnational...

Abstract Globally, sharks are impacted by a wide range of human activities, resulting in many populations being depleted. Trophy large-sized sharks of the Argentinean coast, the sand-tiger Carcharias taurus , the copper Carcharhinus brachyurus and the sevengill shark Notorynchus cepedianus are under intense sport and artisanal fishing since the 50's decade. However, the current and historical information for the assessment of its populations status is scarce. The aim of this work was to analyze the status of conservation of these species through the gathering of expert fishermen knowledge (FK) on semi-structured interviews. Abundance variation perception between the beginning and the end of fishermen careers revealed a critical status for the species study...
