The Fisheries and Fishermen Welfare Department here on Sunday cautioned of stringent action if fishermen use ‘Surukku Vala’ (Purse Seine Net) for fishing. An official release said, in spite of several efforts by the department to prevent fishing using purse seine net, some fishermen villages are still using it. Stringent action against those who use the banned net will be initiated under the Puducherry Sea Fishing Regulator Act 2008, the release said. Purse Seine Nat is banned to ensure the livelihood of all fishermen and to protect the marine resources and hence, the fishermen should cooperate with the department.
