Rao, V Ramamohana and Sekharan, K V and Pradhan, M J (1962) On the mackerel fishery of the Mangalore area during the period 1957-61. Indian Journal of Fisheries , 9A (2). pp. 653-678.



At Mangalore, studies on the mackerel fishery were initiated in 1957. The programme of work was intensified from 1958 onwards and detailed observations were made particularly at Ullal, an important fishing centre near Mangalore. This paper deals with certain interesting observations made during the years 1957-61 at Ullal and other centres in the region between Kasargod and Malpe, especially in regard to growth, maturity, and trends of catches. The von Bertalanffy growth equation has also been applied to the length-frequency data and tentative estimates of the parameters obtained. In order to study the variation in catches in relation to certain factors, the data collected by one of us (K. V. S.) at Malpe during 1954-55 have been incorporated.
