    data summary

    One of the primary objectives of the Indian Ocean Tuna Commission (IOTC) is to develop and maintain an information centre for tuna and tuna-like species in the Indian Ocean (Figure 1). Historical and current fisheries statistics are collected, processed and disseminated for use in the development and management of tuna fisheries. This activity was built on the data collection initiated by the Indo- Pacific Tuna Development and Management Programme (IPTP) between 1982 and 1997. The agreement defining the statutes of IOTC was approved by the FAO Council at its Twenty Sixth Session at the end of 1994, opening the Commission to accession by parties qualified to join. Accession is open to coastal states and to non-coastal states or regional economic integration organisations to which these states have transferred competence over matters within the purview of this Agreement and whose vessels engage in fishing stocks covered by the Agreement within its area of competence. The Agreement entered into force on the accession of the tenth Member on 27 March, 1996. IOTC has twenty one Contracting Parties which are Australia, China, Comoros, Eritrea, France, India, Iran, Japan, the Republic of Korea, Oman, Madagascar, Malaysia, Mauritius, Pakistan, Seychelles, Sri Lanka, Sudan, Thailand, Vanuatu the United Kingdom and the European Union. The First Session of the IOTC was held at the FAO Headquarters in Rome, from 3 to 6 December, 1996. At this session, the member countries chose Seychelles as the location for IOTC headquarters. The Secretariat was established in Seychelles in 1998 and was full staffed by the end of 1999. In the intervening period, the database system has been completely re-designed. In the process of normalisation and transfer of the data, many inconsistencies have been identified and corrected. The database permits entering all data irrespective of the resolution. IOTC collates data supplied by contracting and collaborating parties, including: 1. Annual nominal catch by country, species, gear and IOTC statistical area; 2. Estimates of incidental catch and discards from tuna fishing operations, to the same degree of aggregation as the nominal catch; 3. Catch and effort statistics by species, gear, fishing ground (by 1°x1° or 5°x5° square) and month ; 4. Size-frequency data by species, gear, fishing ground and month; 5. Annual tuna fishing craft statistics aggregated by gear and boat size class; 6. A record of tuna fishing vessels active in the Indian Ocean with details on the vessel, owners and operators; 7. An activity (port call) record of foreign fishing vessels. This Data Summary, No. 22, was compiled from cross-tabulations of the annual nominal catch and fishery fleet statistics from 1991 to 2000. The available nominal catch, catch and effort and size frequency statistics at the Secretariat for the period 1951-2000 are also listed graphically. Nominal catch data are also distributed together with a programme for data query and analysis, FISHSTAT PLUS, available through the IOTC Web site [] or, on request, by e-mail, on magnetic media or CD-ROM.
