Abstract

The results of managing Dermochelys coriacea (Linnaeus, 1766) nests by Projeto TAMAR - IBAMA, in Northern Espírito Santo, Brazil, during the nesting seasons from 1989/90 to 1998/99 are analyzed. The influence of the translocation time on hatching success of the studied nests is discussed. The time translocation, in relation to natural oviposition, seems to increase the number of non-developed eggs found in each nest if translocated between 6 hours and 15 days post egg-laying. There was no relationship established between either the number of yolkless eggs in a translocated nest or the clutch size, with hatching success. The translocation of Dermochelys nests either within 6 hours or after 15 days from natural oviposition is recommended.
