| Abstract: | Nesting and mortality of Lepidochelys olivacea (Eschscholtz, 1829) was studied in 50 km beach stretch along the Nagapattinam coast during December 2000 to May 2001. Lepidochelys olivacea was common constituting 97.1 % of turtles recorded. This species emerged from sea for nesting during December and continued till April. The nesting of Lepidochelys olivacea was sporadic and the peak was observed in the second fortnight of February. The poor nesting (20 nests/ km) in the area could be due to high adult mortality (12 % females) due to incidental catch in the gill nets, and nest predation (> 90 %) by human. The Nagapattinam coast will not sustain the nesting population of Lepidochelys olivacea longer, if immediate conservation measures are not undertaken. |
