Early results from radio-tagging Olive Ridley turtles off Chennai suggest the animals come back to the same nesting sites. This is Tamil Nadu's first telemetry study of the species, which the Advanced Institute for Wildlife Conservation and the Wildlife Institute of India began at the Besant Nagar hatchery in January 2026. Flipper and satellite tags are being used to trace the turtles' movements in the Bay of Bengal. The Forest Department operates 49 hatcheries across 10 coastal districts, safeguarding 1,150 nests holding 1,35,304 eggs, though 680 turtle deaths occurred this season, mostly in the Chennai division.
