DAYA TETAS TELUR PENYU SISIK (Eretmochelys imbricata L.) PADA KEDALAMAN SARANG DAN STRATA TUMPUKAN TELUR BERBEDA

Abstract

The aimed of this research to know the coused of the Hawksbill Turtle (Eretmochelys imbricata L.) population decreased. The World Conservation Union lists them into endangered species. The hatchability of Hawksbill Turtle eggs is 50%. One of the influent factors of it was the nest pattern including the nest-depth and eggs layer. The research conducted factorial CRD with 35, 55, and 75 cm depth nest factor and 1, 2, or 3 egg layers factor. The natural nest became a control group. The data analyzed by ANOVA and DNMRT. The result shows percentage of eggs hatchability based on depth-nest in control, 35, 55, and 75 cm are 91.2%, 83.6%, 23.3% and78.7%. Based on the eggs layer, the eggs hatchability shows in 1, 2, or 3 egg layers and control are 79.12%, 85%, 91.6% and 82.23%. It can conclude that the depth-nest and eggs layer influence the eggs hatchability of Hawksbill Turtle (Eretmochelys imbricata L.)
