Effects of Handling on Hatchability of Eggs of the Leatherback Turtle, Dermochelys coriacea (L.).
Pertanika, 8 (2).

Abstract
The infertility rate among clutches of leatherback sea turtle (Dermochelys coriacea) eggs
incubated in the hatchery at Rantau A bang, Malaysia is estimated at 22%. Variance in hatchability
among fertile clutches ranges from 35.7- 96. 7% (x = 78%) 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.
