The number of purse seiners active in the Western Indian Ocean decreased sharply from an all high of 54 in the first quarter of 1990 to 44 by June. This, however, still represents an increase in the number of active vessels from the same period last year when there were 38 vessels in operation. Fishing results continued to be poor throughout the second quarter, showing only a slight improvement in June. Catch rates were an all time low since 1985 averaging 10.3 MT/day for the quarter compared to 13.5 MT/day for the same period in 1989. The proportion of yellow fin in the catch decreased to 25% in April, 23% in May and then recovered remarkably in June (80%). These results however are not entirely unusual for this time of the year. The fishing pattern followed that established in the preceding years with fishing activities concentrated in the Mozambique Channel during April and May and vessels moving northward by June. This year, however, the fleet was more widely dispersed as vessels moved around to find fish. The poor fishing results might in part be attributed to abnormal oceanographic conditions including the occurrence of the cyclone Kinjo in the second half of May 1990 which even attained the latitude of the Seychelles Group. As determined from seiner logbooks received by the 30th June 1990, the cumulative catch by purse seiners in the Western Indian Ocean for 1990 now stands at 65,781 tones.Pages
