On a Poorly Known Rookery of Green Turtles (Chelonia mydas) Nesting at the Chabahar Beach, Northeastern Gulf of Oman
Tóm tắt
There is a poorly known rookery of green turtles (Chelonia mydas) nesting in sandy beaches of Chabahar town, northeastern Gulf of Oman, Iran.This study has been carried out to evaluate nesting activity of this small rookery in 2014 nesting season (June to October). In this study, total clutches were collected and transferred to an artificial hatchery. The peak of nesting occurred from the third parts of August to the end of September. Mean CCL was 106.3 ± 6 cm and mean CCW was 94.5 ± 5 cm. Females laid on average of 99.42 ± 47.8 eggs per clutch. The mean inter-nesting interval was 18.5 days. The observed clutch frequency was 3.4. Mean hatching success was 36.63 ± 4.1%. The incubation period was 61.07 ± 5.4 days. Nest status evaluation represented that major causes for the failure was unhatched egg with no obvious embryo followed by unhatched eggs with obvious but undeveloped embryos > unhatched eggs with developed embryos > hatched eggs but dead embryos. The results achieved in this study are a valuable contribution to cognition of the reproductive ecology of the green turtle population globally and regionally.
