In a heartening development along the Chennai coast, over 10,000 Olive Ridley turtle hatchlings have recently been released into the sea this week. This significant event marks the culmination of efforts by the Forest Department, non-governmental organisations, and dedicated volunteers to safeguard these vulnerable creatures.
Also known as the Pacific Ridley Sea Turtle, Olive Ridleys are easily recognisable by their heart-shaped shells. Though small, these turtles are abundant and named for their olive-hued carapace, which develops from an initial grey colour as they mature. However, these beautiful creatures are vulnerable due to their reliance on a limited number of nesting sites and the disturbance to these beaches significantly impacting their population.
Since adult Olive Ridleys lay their eggs on beaches under the cover of night, forestry departments, often assisted by NGOs, meticulously collect their soft eggs and transfer them to safeguarded hatcheries built directly on the beaches. The Chennai Students’ Sea Turtle Conservation Network (SSTN) plays a crucial role during this period by organising "turtle walks." These walks allow visitors to witness the collection of eggs before they enter the incubation phase.
This year was no exception and since the beginning of the nesting season, conservationists have been hard at work, collecting over 42,000 eggs from beaches in Besant Nagar, Neelankarai, Kovalam, and Pulicat. These eggs were carefully transferred to hatcheries established along the coastline, where they were nurtured until they were ready to hatch.
Despite a slow start to the nesting season, officials have reported a notable increase in Olive Ridley nesting activity in recent weeks. But the impact of cyclone Michaung, which struck the coast in December 2023, has been evident, with substantial mortality recorded in certain nesting sites. However, in comparison to the previous season, which saw 38,721 hatchlings released, 2024 marks a substantial increase in Chennai's Olive Ridley population.
Recognising the importance of the Tamil Nadu coast as a nesting site for Olive Ridley sea turtles, the Forest Department has intensified conservation efforts. The number of hatcheries has been increased from 35 in 2023 to 45 in 2024. Furthermore, anticipating a harsh summer, ten hatcheries, including two in Chennai, have been outfitted with weather monitors. This crucial technology allows for temperature adjustments within the hatcheries, ensuring optimal conditions for the developing turtles.
Beyond Chennai's Marina Beach and Besant Nagar Beach, witnessing Olive Ridley hatchlings is possible across India. Some prime destinations include Gahirmatha Marine Sanctuary (Odisha), Rushikulya Beach (Odisha), Galgibaga (Goa), and Velas Beach (Maharashtra). Local NGOs often organise "turtle walks" along these coasts. These walks not only provide a chance to see these fascinating creatures up close but also raise awareness about the threats Olive Ridleys face. The IUCN Red List classifies them as "vulnerable."
But if you hope to witness these endearing hatchlings on your next beach trip, remember to minimise noise and movement. Using flashlights or torches should also be avoided, as they can disorient and startle the vulnerable hatchlings. Let's all do our part to ensure a smooth journey for these precious creatures.
