Tuna Purse Seine Shooting Operation Technique of R/V Nippon Maru

Abstract

The fisheries technical assistances by Japan Marine Fisheries Resource Research Center (JAMARC) to Southeast Asian Fisheries Development Center (SEAFDEC/TD) to develop tuna purse seine in the Southeast Asia Region, had been carries out for 10 years. The first tuna fishing technical assistance was conducted in November 1992 to January 1993, by assigning Mr. Aussanee Munprasit to practice and observe on tuna purse seine operations onboard R/V NIPPON MARU. The objective was, to prepare the human resource for the new fisheries/training vessel, M/V SEAFDEC. The observation report on tuna purse seine fishing operations around Seychelles water onboard R/V NIPPON MARU has been released in February 1993. The second tuna fishing technical assistance was conducted for SEAFDEC staff development program of tuna purse seine in December 2000 to April 2001. The second tuna purse seine training had separated into 2 sections. The first section was the tuna purse seine fishing operation training. The training had been conducted by assigning Mr. Isara Chanrachkij attended onboard R/V NIPPON MARU during December 2000 to February 2001. The second section was the practice on tuna processing onboard tuna purse seiner. The training had beenconducted by assigning Mr. Wirote La-ongmanee attended onboard R/V NIPPON MARU during March to April 2001. The observation reports on tuna purse seine fishing operation around Eastern Indian Ocean water onboard R/V Nippon-maru has been submitted to JAMARC, on July 2001. Shooting net operation is one of the most important steps for tuna purse seine fishing operation. The successful of the catch and the trouble hauling net are indicated by the selection of net shooting. The selection is not only the direction of net shooting but also the justification of the suitable time, current and wind condition. Tuna purse seine information has been a part of the purse seine subject for training course since 1993. Fishing participants are always interested in the tuna purse seine fishing operation techniques especially for the shooting selection. This shooting operation catalogue is published to guide participant clearer understanding on net shooting of tuna purse seine. The shooting operation details were collected when the first training/observation in 1992 by Mr. Aussanee Munprasit and the second training/observation in 2001 by Mr. Isara Chanrachkij. The net shooting information was recorded from 68 fishing operations without any serious trouble. The numbers of net shooting operation have been collected enough for publishing, aim to educate by the SEAFDEC participants on the purse seine fishing subject particularly the fishing simulator practice. Authors wish that SEAFDEC participants and people who interested in tuna purse seine fishing operation are able to understand the shooting pattern of tuna purse seine that will lead on the safety tuna purse seine fishing operation.
