| Tagging is considered an excellent tool for estimating the importance of interactions and competition between fisheries as well as to study tuna stocks and migrations. The Regional Tuna Project of the Indian Ocean Commission (IOC) conducted five tagging cruises in the western Indian Ocean, during which 955 fishes were tagged. Out of the total number tagged 15 were recaptured. Tuna tagging in the Indian Ocean was also undertaken by the Indo- Pacific Tuna Programme and by the Japanese National Research Institute of Far Seas Fisheries. 39 tuna marked by these organisations were recovered in Mauritius. Analysis of data collected from the tag recoveries provide some preliminary estimates of growth rate and migration of tuna. Tagging is the most direct method to... |

| The catches made by purse seiners on schools associated with logs constitute more than half of the total catch of the purse-seine fishery of the western Indian Ocean. In the purse-seine fishery on log-associated schools of tuna, either natural logs are spotted by vessels and are marked with radio beacons, or artificial logs are set at sea to concentrate the tuna prior to fishing operations. The first attempt at commercial purse seining was successfully carried out in the Indian Ocean in 1979 by a joint-venture Mauritian vessel using the same technique as the Japanese, who had traditionally fished on schools associated with logs in the Pacific Ocean. They started fishing in the Indian Ocean after experimental purse-seine fishing was conducted by the Japan... |

| The Fisheries division of the Ministry of Fisheries and Cooperatives is involved in research, development, management and protection of fishery resources of Mauritius. It is divided into a Fishery Research and Development Service and a Fisheries Protection Service. The latter section is primarily concerned with the protection of fishery resources and enforcement of Fisheries Act. The Albion Fisheries Research Centre (AFRC), established in 1982, comprises the technical services of the Ministry and is responsible for research and development in the fishery sector. Its activities include resource assessment and management, development of fishing technology, fish quality inspection, studies on the marine environment, establishment of marine parks, and... |

| The AFRC has been conducting research on tuna since 1985 with emphasis on the collection of catch/effort data and length frequency data. A computer system for data collection, codification and processing similar to that which was used in the Atlantic Ocean has been set up at AFRC since 1987 by IRD (ORSTOM) scientists in particular Dr Patrice Cayré. Mauritian technicians have been trained to use the system, to collect tuna data and perform the necessary processing to produce various tuna statistical reports.
