According to Forest department officials, an estimated 26,000 traditional marine fishermen in coastal Kendrapara and Jagatsinghpur districts would be affected by the ban which would remain in force from today till May 31.
The ban has been clamped in accordance with Sections 2, 7 and 4 of Orissa Marine Fishing Regulation Act (OMFRA), 1982 and provisions of Wildlife Protection Act, 1972.
"The prohibitory orders are strictly enforced for the safety of the turtles. Trawl operators have been cautioned not to venture into prohibited water zone. Any act of trespass will invite punitive action," Divisional Forest Officer, Rajnagar Mangrove (wildlife) Forest Division, Kedar Kumar Swain said.
In view of the drop in marine fish catch and subsequent loss of avocation during the ban period, fishermen have been demanding that temporary permits be provided by government for fishing activity once a week.
The breeding turtles get killed by the trawlers which use mono-filament nets that entangles the turtles, said Tushar Sardar, the district president of Traditional Marine Fishermen's union said and claimed that the 'kani' or net used by traditional fishermen did not harm the Olive Ridley Turtles.
