Abstract

The impact of artisanal fisheries on marine turtle populations is still understudied in the southern Caribbean. In the Venezuelan Guajira Peninsula, artisanal fishing of marine turtles by the indigenous Wayuú people has occurred for generations. Nevertheless, understanding the issues regarding turtle take is challenging. Surveys and semi-structured interviews were carried out at eight landing sites located in three different zones in Kazuzain village, Middle Guajira. Carapaces or plastrons were recorded to estimate take level, and measured to determine life stage. Minimum take was 167 marine turtles over 53 weeks, or 3.15 turtles/week on average (estimated 163.8/yr). Most records encountered were from green turtles (n=154; 92.2%), and the majority of these were immature (n=76; 89.4%). Key-informants reported that marine turtles were not the target catch. However, most interviewees affirmed that take of marine turtles in Kazuzain is not only for traditional purposes, but also to meet economic shortfalls. They also stated that trade of marine turtles has increased over the last ten years due to the Venezuelan economic crisis. This is the first assessment of marine turtle take in this village and fills an information gap that can aid resource managers to mitigate the impacts of take, and develop potential conservation solutions for marine turtle aggregations and the people that depend on them.
