The Bulletin aims to improve understanding of the Maldivian marine environment and to promote sustainable utilization of marine resources by providing a means of disseminating relevant information. Each issue is dedicated to a single theme, on any marine topic, but with particular emphasis on fisheries and marine life. Bulletins will include original research results, reviews and manuals. The Maldives Marine Research Bulletin will be published in English with a Dhivehi summary. Information published in any Bulletin may be freely used, but the source should be acknowledged.

In addition to his significant role in the development of marine research in the Maldives, he was well known for his photography. This volume is dedicated to the memory of Maizan Hassan Maniku (1953 – 2002), inspirational Founder Director of the Marine Research Section. Among his numerous achievements, he conceived and launched the Maldives Marine Research Bulletin in 1995 MALDIVES MARINE RESEARCH BULLETIN VOLUME 6 10 DECEMBER 2002 REPORT ON FISHING SURVEY INCLUDING OPINION ON POSSIBILITY OF CANNING FACTORY IN THE MALDIVES BY YOSHITSUGU SHIJI Marine Research Centre Ministry of Fisheries, Agriculture and Marine Resources Male’, Republic of Maldives To be cited as: MRC (2002) Report on fishing survey including opinion on possibility of canning factory in the Maldives – 1962. MMRB 6: 152 pp Shiji, Y. (1962) Report on fishing survey including opinion on possibility of canning factory in the Maldives. Maldives Marine Research Bulletin 6: 139 pp ISBN: 99915-57-04-0 © 2002 Marine Research Centre Ministry of Fisheries, Agriculture and Marine Resources Male’, Republic of Maldives EDITORIAL This volume of the Maldives Marine Research Bulletin reprints a report by Mr. Yoshitsugu Shiji who visited Maldives in 1962 on the request of the Government of Maldives. He was accompanied by a Mr. Sato, and together they conducted a survey on the possibility of establishing a tuna canning factory in the Maldives. They obtained information during the course of two survey trips, during which they visited much of the Maldives. Further data on Maldivian tuna catches was obtained from the Ministry of Home Affairs; these data now give a fascinating snapshot of past catches in the Maldives. The data presented in the report by Mr. Yoshitsugu Shiji is the only available catch and effort data for that period and therefore it is particularly valuable. The surveys carried out by Shiji and Sato suggested to them that the Bonito (skipjack) stock was not a migrating population but one, which lived around the Maldives and had a vigorous appetite for bait. It was recommended that 20 to 50 tons mechanised fishing boats be used for this fishery. Export of frozen tuna to the United States and Europe, and increased production of dried and salted fish using screens to protect the fish from harmful insects were other recommendations for increasing income and resource utilization. Another important recommendation was to conduct a pilot study on a small scale to obtain the necessary data regarding the cost of establishing and managing a canning factory. Careful attention has been given in publishing this report to maintain the format of the original document. Names of atolls and islands have been published as written in the original, not as they are spelt now. A table of these atoll and island names, together with their modern equivalents, is shown at the end of this Bulletin. As there were some very obvious mistakes in the tables, they have been formatted with an additional column showing the corrected totals. However, the figures have been made using the original data. The traces of the two surveys have been done with careful precision in order to obtain an exact replica of the original. All of this could not have been done without the help of all the staff at MRC to whom we would like to express our heartfelt gratitude. We would like to take this opportunity to thank Ms. Fathmath Zeena Ali for word processing, Ms. Aishath Shahindha for word processing and doing all the graphics and Mr. Ibrahim Faizan for creating an almost exact replica of the two survey traces. In addition we would also like to thank Aminath Sheron, Ashiya 4 Abbas, Hussein Mohamed, Ibrahim Asghar, Misbah Ahmed, Miusam Mohamed, Mohamed Ilham, and Mohamed Sudhaau, and for their invaluable help given throughout the different stages of making this bulletin. Special gratitude also goes to the Minister of Fisheries, Agriculture and Marine Resources Honorable Abdul Rasheed Hussein for his continued support and encouragement towards the publishing of the Maldives Marine Research Bulletin. On a more somber note, the Maldives Marine Research Bulletin would not have come into existence if it were not for the hard work and dedication of the late Maizan Hassan Maniku. He was the former Director General of the Marine Research Centre, and the founder of the Maldives Marine Research Bulletin. His passing away in July this year is an irreplaceable loss to the fisheries industry and to the Maldives as a whole. This volume of the Maldives Marine Research Bulletin is dedicated to his memory. May Almighty God rest his soul in peace. Amen.
