'Operation Oliver' to conserve vulnerable turtles
The Coast Guard in Odisha has launched ‘Operation Oliver’ as part of its annual mission to ensure the safe mid-sea visit of breeding Olive Ridley sea turtles in Gahirmatha marine sanctuary area of the State.
The operation is being conducted in collaboration with the forest department in order to keep watch and vigil on illegal fishing along the turtle concentration zone.
The authorities have also deployed a state-of-the-art CG ship and a dornier aircraft for the exercise for surveillance on trespassing and keep an eye on illegal fishing in Gahirmatha marine sanctuary. The coast guard has organized interactive sessions with fishermen communities to sensitize them on the legal embargo on fishing during Ridleys’ nesting season.
It is worth recalling that the Odisha Government recently imposed a 7-month fishing ban within 20 km from the river mouths of Dhamara, Devi and Rusikulya in Gamjam district to protect nests of endangered Olive Ridley sea turtles. The ban on the 20 km span of the Dhamra-Rushikulya river mouth has been imposed in accordance with Sections 2, 7 and 4 of the Orissa Marine Fishing Regulation Act, 1982. These prohibitory orders are now enforced every year to ensure the safety of turtles.
