The Wildlife Management Authority, in collaboration with the Coringa Wildlife Sanctuary, has successfully conserved nearly 20,000 Olive Ridley turtle eggs on Hope Island in Kakinada Bay, Andhra Pradesh. This highlights the growing importance of the East Coast, beyond Odisha, as a critical habitat for marine conservation.

Hope Island: A Sanctuary in Kakinada Bay

Hope Island serves as a vital nesting ground in Andhra Pradesh. Conservationists utilize the in-situ conservation method, where eggs are protected in their natural nesting environment to ensure higher hatching success and maintain the ecological balance of the bay.

Species Profile: Olive Ridley Turtles (Lepidochelys olivacea)

• Physical Characteristics: They are the world’s smallest and most abundant sea turtles. They are recognized by their unique heart-shaped, olive or grayish-green carapace.
• Habitat: Primarily found in the tropical waters of the Pacific, Indian, and Atlantic Oceans, inhabiting both the open sea and coastal regions.
• Diet: Being omnivorous, they feed on a variety of marine life including jellyfish, snails, crabs, and shrimp/algae.
• Behavioral Phenomemon (Arribada): They are famous for "Arribada"—a Spanish term for "arrival"—which refers to the synchronized mass nesting where thousands of females come ashore simultaneously to lay eggs (approx. 100–140 eggs per female).

Distribution and Key Indian Nesting Sites

The turtles undertake massive migrations from the Pacific toward the Indian coast, typically arriving between November and December and staying until April–May.

• Odisha: Home to the world's largest nesting sites, including Gahirmatha Marine Sanctuary, Rushikulya, and the Devi River mouth.
• Andhra Pradesh: Increasingly significant sites in Kakinada (Hope Island) and Visakhapatnam.
• Others: Andaman and Nicobar Islands and parts of the Tamil Nadu coast.

Conservation Status and Legal Framework

To mitigate the decline in population, Olive Ridleys are afforded the highest level of protection:

• IUCN Red List: Vulnerable.
• Wildlife Protection Act (WPA), 1972: Schedule I (highest protection in India).
• CITES: Appendix I (prohibits international trade).
• CMS (Convention on Migratory Species): Protected under this global intergovernmental treaty.

Threats and Protection Measures

Despite legal safeguards, the species faces multifaceted challenges:

• Major Threats:
  • Bycatch: Accidental entanglement in trawl and gill nets is the leading cause of mortality.
  • Poaching: Illegal trade of eggs and meat.
  • Habitat Loss: Coastal erosion and light pollution (which disorients hatchlings).
• Key Conservation Initiatives:
  • Operation Olivia: An annual mission by the Indian Coast Guard to enforce seasonal fishing bans and protect nesting sites.
  • Turtle Excluder Devices (TEDs): Mandated for use in trawl nets to allow turtles to escape while retaining the fish catch.
  • Tagging Programs: Using metal tags to track migration patterns and nesting frequency.
