Mechanised boats did not set sail off Thoothukudi coast on Tuesday as they mourned the death of a Rameswaram fisherman at sea. Arulraj, 52, a native of Thangachimadam in Rameswaram, died of heart attack 10 nautical miles off the coast around 5.30 p.m on Monday, when 177 mechanised boats went fishing for the first time in nearly nine months. Out of them, as many as 142 boats were unregistered. Nevertheless, the boats returned without any incident on Monday. Joint Director of Fisheries R. Amal Xavier said that a chargesheet would be filed against the owners of 142 unregistered boats, and they would be summoned for an enquiry. He said that action would be taken based on the outcome of the enquiry. Assistant Director Sivaramachandran said that the process of filing chargesheets had started and they would be submitted to the JD’s office soon. Meanwhile, a weather advisory cautioning fishermen to be careful while venturing into sea has been put up at the harbour here. When many fishermen set sail after a long period, such a warning has come as a dampener. Sources said that nearly ? 3 to ?4 crore-worth fish was netted on Monday. For the number of fishermen and boats that went for fishing, the catch was on the higher side, they added. M. Samy, president of Annai Teresa Boat Owners’ Association, said that varieties such as paarai, ooli and kaaral were caught in large quantities. While a majority of fishermen were happy about the catch, they expressed concern over the fuel price, which touched a new high, that ate away their income.
