Olive Ridley Turtle Deaths Raise Alarm in Andhra Pradesh
Why in the News?
As the Olive Ridley turtle nesting season begins along the Visakhapatnam–Anakapalli coastline, several turtle carcasses have washed ashore, alarming conservationists. At least three dead Olive Ridley turtles were found at Muthyalammapalem, Thantadi, and Rajanapalem beaches, likely due to entanglement in fishing nets. With the Forest Department planning to set up new nesting zones, concerns have also been raised about the impact of artificial lighting and coastal activity during the nesting period.
Background
- Olive Ridley turtles (Lepidochelys olivacea) are listed as ‘Vulnerable’ under the IUCN Red List.
- India hosts one of the largest nesting populations globally — especially along the East Coast.
- Nesting season: December to April
- The Andhra Pradesh coastline is a significant nesting habitat, particularly around Visakhapatnam.
- The turtles migrate long distances and return to sandy beaches to lay eggs.
Key threats include:
- Fishing nets
- Coastal pollution
- Artificial lighting
- Tourism disturbances
Features
Recent incident
- Three dead turtles were found on Visakhapatnam beaches.
- Believed cause: drowning after entanglement in fishing nets.
Biology note
- Turtles need to surface every 40–45 minutes to breathe.
- If trapped underwater, they suffocate.
Legal protection
- Andhra Pradesh Marine Fishing Regulation Act
- Restricts illegal fishing within 8 km of the coast
Conservation action
- Forest Department to create four nesting zones
- Collaboration with The Tree Foundation
- Four hatcheries to operate along the coast
- Special protection planned during Visakha Utsav (Jan 23–31)
Concern
- Artificial lighting disorients turtles
- affects nesting females
- confuses hatchlings who rely on moonlight reflection to reach the sea
Challenges
Bycatch Mortality
- Lack of Turtle Excluder Devices (TEDs) in fishing nets
- Non-compliance with coastal fishing regulations
Artificial Lighting & Tourism
- Bright lights disturb nesting behaviour
- Night-time beachfront activity causes stress
Habitat Disturbance
- Beach erosion, vehicles, and littering
Weak Enforcement
- Monitoring gaps in no-fishing zones
Awareness Deficit
- Many fishermen are unaware of the ecological impacts.
Climate Stress
- Rising sea levels and temperature shifts affect hatchling survival.
Way Forward
Strict Enforcement of Coastal Fishing Rules
- Ban mechanised fishing near nesting beaches during the season
Mandatory Use of Turtle Excluder Devices (TEDs)
- Training and subsidisation for fishermen
Light Pollution Control
- Shielded, downward-facing lights near beaches
- Night-time illumination restrictions during nesting
Community-Based Conservation
- Engage local fishing communities as partners
Scientific Monitoring
- Track nesting data, mortality causes, and beach health.
Eco-Sensitive Tourism Guidelines
- Restrict beach vehicle movement
- Create silent, dark turtle zones
Education & Outreach
- Awareness programmes for schools & coastal residents
Conclusion
The deaths of Olive Ridley turtles at the onset of nesting season highlight the fragile balance between marine ecology and human activity on Andhra Pradesh’s coast. While government initiatives such as hatchery development and nesting zone creation are welcome steps, effective enforcement, community participation, and mitigation of fishing-related mortality are crucial to safeguarding this vulnerable species.
