Splitting the eggs methods: Comparison of egg survivorship between styrofoam and open area nests for Penang Island and turtle conservation

This research paper reports the observation of successful hatching comparing Styrofoam and Open Area nest. Splitting the eggs method was studied using green turtle (Chelonia mydas) clutch size whereby they were divided equally and incubated in two nest plots (Styrofoam and Open Area). The aim of t...

Splitting the eggs method shows that Open Area nest produced a good rate of hatching success and hatchling morphological characteristics. It is recommended to further this study to test the hatchling physical performance between Styrofoam and Open Area nest, as high energy reserved within individual’s hatchling body does impact their longer survival to face the ocean’s predator and also for a greater fitness.
