Odisha begins seven-month fishing ban to protect Olive Ridley turtles; turtle excluder devices now compulsory
In 60 seconds: Odisha's annual seven-month fishing ban to protect nesting Olive Ridley turtles began on 1 November and will last until 31 May 2027. Fishing is barred within 20 km of the coast in the Gahirmatha marine sanctuary. Fourteen protection camps and four patrol boats will enforce the ban, and trawlers must now carry turtle excluder devices. Odisha hosts about half the world's Olive Ridleys.
Why it matters
Odisha is home to half the world's Olive Ridleys. Protecting them also matters for trade, as US curbs on Indian shrimp are linked to turtle-safe fishing.
Explain it simply
It's like a 'quiet zone' outside a hospital: for seven months the sea off Gahirmatha becomes a maternity ward for turtles.
The 3-minute read
What happened
The forest department has set up 14 turtle protection camps, including four offshore camps on Madali, Sasanipada, Ekakula and Babubali islands, backed by marine police and the Coast Guard.
Background
Odisha hosts about half the world's Olive Ridleys and about 90% of India's. In 2025 an estimated 6,06,933 turtles nested at Gahirmatha in March, but no mass nesting happened in 2026.
How it works
A turtle excluder device is a grid fitted in a trawl net that lets turtles escape while fish stay in. MPEDA gave 1,200 of them, each costing ₹28,000, free to Odisha trawler owners in October.
What's next
Officials expect large numbers of turtles to nest this season. A forest officer said a missed mass nesting in one year is natural and does not by itself signal a decline.
What it means for you
Fishers fear a 10–20% fall in catch, but MPEDA studies put the loss at 1–5%. When facts and fears differ, look for the data.
Key numbers
- 7 months: Length of the fishing ban (1 Nov–31 May)
- 20 km: No-fishing zone from the Gahirmatha coast
- ~50%: Share of the world's Olive Ridleys that come to Odisha
Both sides
- Forest department and MPEDA: The ban and turtle excluder devices protect turtles and could help lift US curbs on Indian seafood.
- Fishers: Seven months without fishing near the coast and new gear hit incomes; they fear smaller catches.
Key terms explained
- Olive Ridley turtle
- A small sea turtle known for mass nesting on a few beaches, including Odisha's Gahirmatha and Rushikulya.
- Turtle excluder device
- A grid fitted in fishing trawl nets that lets trapped sea turtles escape.
The story so far
- 1997: Gahirmatha in Kendrapara district is declared a marine sanctuary. The sanctuary covers 1,435 sq km of sea between Hukitola and Dhamara and is a major Olive Ridley nesting ground.
- 2019: The US restricts imports of wild-caught shrimp from India over sea turtle bycatch. MPEDA estimates the curbs have cost India about ₹4,500 crore; wild-caught shrimp exports fell from 1,53,286 tonnes in 2018-19 to 65,882 tonnes in 2023-24.
- Today: Odisha's seven-month fishing ban for Olive Ridleys begins
Exam notes (UPSC, SSC, Banking, PSC)
- Olive Ridley (Lepidochelys olivacea) is listed as Vulnerable on the IUCN Red List and protected under Schedule I of the Wildlife (Protection) Act, 1972.
- Mass nesting of Olive Ridleys is called 'arribada'; Gahirmatha and Rushikulya are major arribada sites in Odisha.
- Gahirmatha Marine Sanctuary in Kendrapara district was declared in 1997.
- The Marine Products Export Development Authority (MPEDA) works under the Ministry of Commerce and Industry.
