“The authorities cleaned only 2 km—3 km stretch of the beach. Many eggs were damaged due to the effect of oil deposits. Moreover, many baby turtles failed to move out of the nest as the soil also got harder，” Sahu, who along with villagers of Purunabandha has been working in the turtle conservation programme in the last 16 years, said.

　　Turtle expert Kartik Shanker also raised similar concerns. “The oil spill will have an effect on the mortality rate of the hatchlings. But scientifically, it is not possible to arrive at a mortality figure for it，” Shanker, a professor at the Indian Institute of Science, Bengaluru, said.

　　Marine scientist Bijay Kumar Sahu said there was an immediate need for a detailed multi­discipline faculty study on the long­term impact of the oil spill on the marine environment. State forest and wildlife officials, however, refuted (反驳) the claims. “The oil spill has had no effect on the hatching process. Oil was cleaned from the beach a long time ago and the issue is now a closed chapter，” the state's Chief Conservator of Forests (Wildlife), Srivastava said.

　　The mortality rate of the hatchings is usually high with only one out of every thousand surviving to become an adult turtle. “Out of around 100­120 eggs laid by a single female turtle, only about 80 of them hatch. The new­borns then face threats from predators like crows, jackals, etc. They also get eaten up by sea predators，” wildlife activist Biswajit Mohanty said.
