Chennai, Jan 18 (NationPress) The nesting behavior of Olive Ridley turtles is steadily increasing along the coastal delta of Tamil Nadu, particularly in the districts of Mayiladuthurai and Nagapattinam, following a slow onset this season.
According to data from the Forest Department, a total of 48 nests have been documented in Mayiladuthurai and 24 in Nagapattinam, resulting in over 9,000 eggs collected thus far this season.
This year's nesting period commenced later than anticipated, especially in Mayiladuthurai. While Nagapattinam recorded its first nesting on December 13, Mayiladuthurai did not see its first nesting until December 31, 2025.
Officials noted that the delay in turtle arrivals was due to unfavorable sea conditions and compacted, waterlogged beaches, which presented challenges for the turtles to reach the shore for egg-laying during the initial part of the season.
With sea conditions improving gradually, authorities are optimistic about an increase in nesting activity in the upcoming weeks.
February is usually the peak nesting time along this coastal stretch, and officials are hopeful for the arrival of more turtles as tidal and weather conditions become more favorable.
In Mayiladuthurai, 5,750 eggs have been secured from the 48 nests identified so far. Nagapattinam, which started nesting activity earlier, has collected 3,574 eggs from 24 nests to date.
However, persistent rainfall in recent days has hindered night patrols and monitoring efforts, resulting in no significant increase in nesting counts during that time.
Forest officials expect a surge in nesting activity over the weekend, coinciding with the new moon. Olive Ridley turtles have a tendency to come ashore in greater numbers during new and full moon phases when spring tides create higher water levels, facilitating their access to nesting sites.
Nagapattinam district is currently home to nine hatcheries, including five permanent and four temporary facilities located across the Nagapattinam and Vedaranyam forest ranges.
Mayiladuthurai operates 11 hatcheries, consisting of three permanent and eight temporary units within the Sirkazhi and Mayiladuthurai forest ranges.
Nesting sites are being geo-tagged, and officials have indicated that additional shelters and temporary watchers could enhance protection in vulnerable coastal areas.
In addition to nesting, turtle mortality is also under surveillance. To date, nine turtle carcasses have been identified in Nagapattinam district, while Mayiladuthurai has reported no carcasses.
To promote safer nesting conditions, the Fisheries and Forest Departments have ramped up awareness initiatives in coastal villages, focusing on the preservation of nesting sites, minimizing disturbances, and protecting the delicate coastal ecosystem that is crucial for the survival of Olive Ridley turtles.
Point of View
It’s essential to highlight the significance of Olive Ridley turtles' nesting activities along Tamil Nadu's coastal delta. Their resurgence signifies not only a success for conservation efforts but also a reminder of the delicate balance we must maintain in our coastal ecosystems. With the continued support of local communities and authorities, we can hope for a thriving future for these remarkable turtles.
