During the same period last year a maximum of 46 vessels were in operation.Poor fishing results obtained during the second quarter continued throughout July and August, with daily catch rates averaging 11-13 MT. In September, however, fishing success improved considerably with catch rates rising to 26.5 MT/day, nearly reaching the level obtained (30 MT/day during the same period last year.
