The annual breeding and nesting season of Olive Ridley sea turtles has commenced along the Odisha coast near the Rushikulya river mouth in Ganjam district. This natural phenomenon, locally known as arribada, involves thousands of female turtles coming ashore simultaneously to lay eggs on sandy beaches. Rushikulya is recognized as one of the most significant mass nesting sites for Olive Ridley turtles in the world, along with Gahirmatha and Devi river mouth in Odisha.
Forest and wildlife authorities have confirmed the arrival of turtles in nearshore waters, indicating the beginning of the nesting cycle. The breeding season generally starts in December and continues until March, with peak nesting activity usually observed between January and February. During this period, the turtles travel long distances from the Indian Ocean to return to the beaches where they were born.
To protect the endangered species, the Odisha Forest Department has intensified monitoring along the coastline. Patrolling has been increased both on land and at sea to prevent disturbances. Fishing activities have been temporarily restricted within a designated marine zone under the provisions of the Odisha Marine Fishing Regulation Act. Trawler movements are closely monitored, and mechanized fishing is banned during the nesting period to reduce accidental turtle deaths.
Authorities have also taken steps to minimize artificial lighting along the nesting beaches, as bright lights can disorient turtles and hatchlings. Local communities, volunteers, and conservation groups are actively involved in awareness campaigns, helping to safeguard nests and guide hatchlings toward the sea.
Olive Ridley turtles are listed as vulnerable under the International Union for Conservation of Nature Red List and are protected under India’s Wildlife Protection Act, 1972. Odisha plays a crucial role in the global conservation of this species, as the state hosts the largest known nesting population.
The Rushikulya rookery has gained importance in recent years due to consistent mass nesting events and successful hatchling emergence. Scientists and researchers closely observe the nesting patterns, as they provide valuable data on marine biodiversity, climate change impacts, and coastal ecosystem health.
With coordinated efforts by the government, conservationists, and local residents, officials hope for a successful nesting season. The annual arrival of Olive Ridley turtles not only highlights Odisha’s rich natural heritage but also reinforces the importance of sustainable coastal management and wildlife conservation.
