Researchers said that with this, they can
confirm a long-held speculation that Olive Ridleys in Maharashtra nest more
than once in a single season.
Savani had earlier
laid 87 eggs at Anjarle beach
A female Olive Ridley turtle, nicknamed
‘Savani’, who was fitted with a satellite tracker at Anjarle beach in Ratnagiri
district on January 25, delivered 76 eggs on Friday at the adjacent Kelshi
beach (her second nesting in a span of one month).
Two turtles, Prathama and Saavani, were
the first to be fitted with satellite trackers to monitor their movements. They
were released from Velas and Anjarle beach in Ratnagiri on January 25.
Of the two, Prathama has since travelled
about 75kms south of the coastline, while Saavani remained in shallower waters
closer to the shore, returning to lay eggs once again on Friday. Both turtles
are expected to venture into deeper waters sometime in March after a change in
prevailing currents. It is currently speculated that the Ridleys move toward
either the Middle East, Pakistan or towards Sri Lanka after laying eggs in
Maharashtra.
No further
satellite tagging of Olive Ridleys is to be carried out as part of the study.
“Only their movements will be monitored,” said
VirendraTiwari, APCCF, mangrove cell. While satellite monitoring of Olive
Ridleys -- whose conservation status has been assessed as ‘vulnerable’ by the
International Union for the Conservation of Nature (IUCN) -- has been
previously carried out on India’s east coast, this marks the first time such a
study has been commissioned in the west. The study received approval in October
2020, during the third governing body meeting of the Mangrove Foundation
Conservation needs
to be looked at as a landscape issue,
R Suresh, a scientist
who researches sea turtles at the Wildlife Institute of India, said the
researchers have always held that sea turtles have a fidelity to their nesting
sites and that they nest multiple times. “But what we have seen today is that
the turtle has nested a second time at an adjacent beach. So, conservation
needs to be looked at as a landscape issue, and the entire coastline requires
protection. Not just individual beaches. Perhaps the turtles are regulating the
sex of the hatchlings by nesting on beaches with different properties that
helps regulate the temperature of the nests. Further study may give us a better
idea on this,” he said. |
