Abstract

The infertility rate among clutches of leatherback sea turtle in Malaysia is estimated at 22. Variance in hatchability among fertile clutches ranges from 35.7-96.7 for eggs handled with maximum care. For such eggs hatchability did not show a correlation with the time between oviposition and reburial. Leatherback eggs can tolerate rough handling only up to 5 hours after oviposition. Beyond this threshold careful handling to prevent rolling bumping rotation and disorientation of the vertical axis will enhance hatch rates
