There is a ban on mechanised fishing boats in a five nautical mile area during the three-month nesting season. Gill nets which trap turtles and don't allow them to breathe till boats reach shores are also banned, but conservationists blame fishermen for violations.
Shravan Krishnan, a conservationist, says, "We've introduced nets that have LED lights, which repel turtles, and excluder devices which allow them to escape through openings. These openings may allow around two per cent of the fish to escape which is why fishermen don't use these nets."
It's heart-breaking to find dead turtles tangled in nets with the soft tissue of their neck and fins sliced by nylon strings along the beaches.
However, he denies alegations that mechanised boats violate the fishing ban in the five nautical mile area. He said, "That zone is exclusively meant for fishermen with country crafts (non-mechanised boats), who wouldn't let mechanised boats here as it would ruin their livelihood."
The endangered Oliver Ridley turtles, well-known for their coordinated nesting in large numbers, mostly breed between January and March in southern India. After nesting, the female turtles swim ashore to lay eggs by digging pits in the sand. The hatchlings emerge 45 to 50 days after nesting. The female turtles, however, do not wait to see their eggs hatch and return to the sea.
