Introduction
|
The Southwestern Atlantic Ocean is an important developmental area for juvenile loggerhead sea turtles. Previous research has shown that individuals belonging to diverse nesting populations congregate at this productive area to feed.
This area is also exploited by several pelagic longline fleets, which incidentally capture juvenile loggerhead sea turtles in large numbers throughout the entire year. The capture rates reported for this region are among the highest worldwide. The Uruguayan pelagic longline fleet (targeting mainly swordfish, tunas and sharks) has been continuously monitored by the Programa Nacional de Observadores Abordo de la Flota Atunera Uruguaya (PNOFA) since 1998. PNOFA’s scientific observers record data of the catch as well as fishing gear and operative.
Since early 2008, PNOFA observers have deployed a total of 13 PTTs (SPOT and SPLASH (Wildlife Computers)) on juvenile loggerhead sea turtles captured as bycatch in Uruguay's pelagic longline fishery. The aims of this study are to understand the movements and habitat use of satellite tracked loggerhead sea turtles and their overlap with fisheries operating in the Southwestern Atlantic Ocean. Additionally, tracking data will be used to evaluate the lethal and sub-lethal effects of a capture event on these turtles.

El Atlántico Suroccidental es una importante área de desarrollo de tortugas cabezonas juveniles. Investigaciones previas han demostrado que individuos pertenecientes a diversas poblaciones anidadoras se congregan en esta productiva área para alimentarse.
Esta área es también utilizada por varias flotas de palangre pelágico, las cuales capturan incidentalmente tortugas cabezonas juveniles en grandes cantidades a lo largo de todo el año, con tasas de captura que se encuentran entre las más altas a nivel mundial. La pesquería con palangre pelágico de Uruguay (dirigida al pez espada, atunes y tiburones) ha sido monitoreada continuamente por el Programa Nacional de Observadores Abordo de la Flota Atunera Uruguaya (PNOFA) desde 1998. Los observadores de PNOFA registran datos de la captura y también del arte y operativa pesquera.
Desde inicios del 2008, observadores del PNOFA han colocado un total de 13 transmisores satelitales (SPOT y SPLASH, Wildlife Computers) en juveniles de tortuga cabezona capturados incidentalmente por la flota palangrera Uruguaya. Los objetivos de este estudio son entender los movimientos y uso de hábitat de estas tortugas y su solapamiento con las pesquerías operando en el Atlántico Suroccidental. Adicionalmente, los datos de rastreo serán utilizados para evaluar los efectos letales y no letales de la captura incidental en estos individuos.
