Apparent survival probability and abundance of juvenile green turtles in the foraging ground at Kuroshima Island, Ryukyu Archipelago

An understanding of the survival probability and abundance endangered species is critical for their effective conservation management. In this study, long-term capture-mark-recapture data were used to estimate apparent green turtles Chelonia mydas at Kuroshima Island in Yaeyama Islands, Japan. A total 453 captured from 2009 2020 using entangling nets. All juveniles subadults; no adult during study. The estimated rate aggregation was 0.82 (95% CI = 0.76-0.86) Cormack-Jolly-Seber model, which accounts both permanent emigration death. Annual Horvitz-Thompson estimator. Estimated increased 234 182-286) 418 325-510) 2020. This trend foraging ground may result increasing nesting population region.
