Abstract

This paper deals with the mackerel fishery of Calicut area for the years 1959-60 to 1967-68. Monthly figures of efi'ort, catch and catch/eff'ort for each gear as well as standard effort, catch and catch/standard efi'ort for each month and each season are given. Though the total landings showed considerable fluctuations from year to year, the catch trends indicated that there was a marked improvement in the fishery every third year followed by a fall in the catches in the next two successive years. In 1959-60, 1961-62, 1962-63 and 1964-65 fishing seasons, when the catch returns were high, an increase in effort could have resulted in higher landings
