Pengaruh Kedalaman Sarang Terhadap Daya Tetas Telur Penyu Lekang (Lepidochelys olivacea Escholtz, 1829) di Kawasan Penangkaran Penyu Kota Pariaman

Abstract

This study aims to determine the hatchability of Olive Ridley Sea Turtle eggs at different nest depths. This is an experimental research that used a Completely Randomized Design (CRD) with four nest depths P1:30 cm, P2:40 cm, P3:50 cm, P4:60 cm and 4 repetition with each nest filled with 10 eggs. Environmental nest temperatureair and air humidity were measured during the incubation period. The number of hatched eggs collected on day 60 incubation or when the moment hatchlings reveal at nest surface. Data collected after 60 days incubation as the average percentage of hatched eggs and test by ANOVA, with Duncan New Multiple Range Test (DNMRT). The result showed the average of percentage hatchability P1 92.5%, P2 90.0%, P3 82.5% and P4 60%. Based on statistical analysis the P1, P2, and P3 increased hatchability significantly higher (p<0,05) compared to P4. From the results studied it can be concluded that the nest depth has influenced egg hatchability of Olive Ridley Sea Turtle in Turtle Breeding of Pariaman City.
