Resumo: 	The number of purse seiners active in the western Indian Ocean averaged 53 during the first quarter compared to 41 vessels during the same period last year.  Fishing activity was high during the first half of the year with a record for the month of March of 55 licensed vessels. The fishing results for the first quarter were not as good as those previously recorded in the last three years, however there are still 28 logbooks outstanding at the time of publication.  Catch rates averaged 14.6 MT/day compared to 22MT/day in 1991 and 26MT/day in 1990.  The high number of vessels licensed during the first quarter can be attributed to increased number of licenses issued to French and Japanese vessles. 1992 has been a notably strong El Nino year, giving rise to a dramatic change in climatic and oceanograhic conditions.  This, however, has resulted in a higher than normal concentration of fishing activity in the Mozambique Channel during the first quarter.  The purse seine fleet has yet to start intensive fishing in the western Indian Ocean.  The usual high percentage of yellowfin tuna in the first quarter catch statistics cannot be observed for this year.  The catch has been dominated by skipjack, which in previous years, especially 1991 had a much lower percentage of the Western Indian Ocean based on logbooks received by 31st March, stands at 42 787 MT for 1992. Transhipment in Port Victoria, during the first quarter, shows that more skipjack is being transhipped than yellowfin.  The number of vessels transhipping is relatively high at 111 vessels compared to the 1991 figure of 77 vessels.  However the total weight of fish transhipped is less than the 1991 figure, of 47 151 MT, at 45 415 MT. During 1991 two new fishing agreements were signed, one with Japan allowing for more Japanese purse seiners to obtain fishing licenses.  The other agreement was with Iran permitting two seiners to fish within the Seychelles EEZ.
