The Fisheries Deputy Director has given instructions to fishermen to stay off prohibited fishing practices as the department has imposed a strict ban on unscientific techniques impacting marine biodiversity. Use of LED lights, explosives such as dynamite, poisonous substances, pair trawling and banned nets will not be permitted as per Kerala Marine Fishing Regulation Act. Legal action would be taken against those violating the ban and their vessels would be impounded, department officials said. Boats seized During a patrolling session on Tuesday night, marine enforcement had seized boats from Vaady, Moothakkara, Thangassery and Eravipuram for employing prohibited fishing techniques. The officials had strengthened surveillance following a tip off that artificial lights are being used to attract fish. Also seized They also seized batteries, lights, thermocol and other equipment during the inspection. The monitoring will continue in the coming days and strict legal measures will be taken against owners of seized fishing boats,” said the officials.
