  Se describen los procesos de conservación y ecología de anidación de la tortuga carey (Eretmochelys imbricata), producto del monitoreo sistemático entre 2018 y 2019 en el corregimiento de Rincón del Mar, San Onofre, Sucre. Se registraron seis nidadasde tortuga carey, todos fueron dejadas in situ y un nido fue saqueado por humanos. Las hembras desovaron un total de 761 huevosen cinco nidadas (promedio ± DE: 152,2 ± 15,5 huevos por nidada). El éxito de eclosión fue en promedio 78,2 ± 12,4 % y el éxito deemergencia fue en promedio 74,7 ± 14,1 % (n = 5). El periodo de incubación fue en promedio de 54 ± 7,8 días (n = 4). Fueron liberadas 591 crías al mar, de las cuales 22 (3,72 %), fueron rescatadas y liberadas con la comunidad. Además, se realizaron mediciones físicas de los nidos (ancho, profundidad, distancia a la playa), medidas morfométricas de los neonatos (ARC, LRC y peso) y se identificaron amenazas en el sector. Nuestros resultados contribuyen al conocimiento del estado actual de la tortuga carey, así como lo indispensable de la participación comunitaria para su conservación en Rincón del Mar.

  The conservation and nesting ecology processes of the hawksbill turtle (Eretmochelys imbricata) are described, as a result of systematic monitoring between 2018 and 2019 in the municipality of Rincón del Mar, San Onofre, Sucre. Between July and September, day and night patrols were carried out a 7 km stretch of beach with 1674 hours of effort for the two years. Six hawksbill turtle nests were recorded in situ, one nest was poached by humans. The nesting female spawned a total of 761 eggs in five clutches (mean ± SD: 152.2 ± 15.5 eggs per clutch). Hatching success was (mean ± SD: 78.2 ± 12.4%) and emergence success was (mean ± SD: 74.7 ± 14.1%) (n = 5). The incubation period was (mean ± SD: 54 ± 7.8 days; n = 4). 591 hatchlings were released into the sea, of which 22 (3.72%) were rescued and released with the community. In addition, physical measurements of the nests (width, depth, distance to the beach) and morphometric measurements of the hatchlings (SCW, SLC and weight) were carried out. More than 120 people participated in the different environmental education activities: local experts, releases, beach clean-ups, workshops, training and awareness. Finally, 14 natural and anthropogenic threats were identified for the species in Rincón del Mar and different degrees of threat, according to the beach sector, being high, medium and low for Chichimán, Ana Gómez and Balsillas with Punta Gorda respectively. Our results to contribute to the knowledge of the current status of the hawksbill turtle, as well as the indispensable of community participation, the importance of systematic and standardized monitoring, and the urgency of generating plans and management units for their conservation in Rincón del Mar.
