A total of 2363 nests were collected with 2,58,775 eggs, which were meticulously translocated to departmental hatcheries. Monitoring was carried out 24/7 in all these hatcheries right from the translocation till release of every hatchling. While doing so all the parameters were recorded including temperature of all the nests. The department released 2,15,778 hatchings this year, which is the highest ever recorded so far.
