The mass nesting commenced on March 10 and concluded on March 24, DFO of Rajnagar Mangrove Forest and Wildlife Division Bikash Ranjan Dash said.
He said this time less numbers of endangered Olive ridley sea turtles reported for laying eggs at Nasi -2, the favourite nesting place of the endangered species within Gahirmatha marine sanctuary.
Last year over 4.07 lakh of female Olive Ridley sea turtles had laid eggs at Nasi -2, but this year the mass nesting figure remains only 3.49 lakh.

Mr. Dash said an interesting fact is - a couple of tagged Female Olive Ridley sea turtles which were tagged in 1998-99, also came to lay eggs once again to Gahirmatha Marine sanctuary, the largest rookery of the species.
This proved that tagged female turtles are finding their way to Gahirmatha, where they had come earlier for laying eggs.
It has been now ascertained that the turtles generally come to the favourite nesting place again and again for laying eggs at the golden beach of Gahirmatha where they earlier laid egg, the DFO said.
Even, this year, the researchers of Zoological Survey of India have tagged about 1060 female Olive Ridley sea turtles at the Nasi -2 beach to ascertain their behaviour, migratory route and areas of foraging.
The endangered species rarely turn up in such large numbers anywhere on the planet which comes en-masse to the golden beaches of Gahirmatha marine sanctuary for laying eggs.
The Gahirmatha marine Sanctuary, instead of being the beacon of life has turned into a bane for Olive Ridley as more than 10 percent of eggs laid were destroyed due to over layering during the mass nesting period as turtles came to lay eggs on the same spot where other turtles earlier laid eggs.
Turtles lay their eggs at midnight in 45 centimeters pits, which they dig 2-3 foot long pits to lay eggs with their rear flippers.
After laying the eggs in the pits, the female turtles cover the nests with sand and return to the sea in a zigzag manner to confuse predators about the location of the nests.
After laying eggs they returned into the deep sea water. Hatchlings emerge from these eggs after 45-60 days and find their way to the sea creating a cacophony.
It is one of Nature’s rare phenomena where babies grow without their mother. (UNI)
