Principal Chief Conservator of Forests and Chief Wildlife Warden of the state Forest Department V K Melkani told the court about the matter after the court suo motu took up as PIL a report on Olive Ridley turtle deaths published in an English daily.
Earlier, the First Bench, comprising Chief Justice Sanjay Kishan Kaul and Justice M M Sundresh, decided to take up the report on mass deaths of sea turtles as a PIL. It also appointed an amicus curiae to assist the court.
Listing the awareness campaigns organized by the department in the past five years, the officer said "there is almost no incident of turtle poaching from the year 2012-13 onwards."
The officer admitted that Tamil Nadu forest department had not taken any specific and authentic study on turtle mortality but said that it had been observed from various sources/students that trawlers and various destructive fishing practices caused trouble.
The First Bench adjourned the matter to April 1 for further hearing.
