The burgeoning world population has prompted mankind to. exploit new and varied avenues for acquiring food. The sea is often seen as a vast and endless source of food for mankind. The f.ishery resources of the sea have been exploited by man from time immemorial and the recent rapid strides in technology have enabled him to utilise the vast and deep expanses of the oceans effectively. The total annual world fish production is estimated as 92.86 million tonnes in 1999. Of this, production from marine fisheries alone accounted for 84.6 million tonnes (FAO, 1999). India ranks eighth (FAO, 1999) in the total fish production in the world. With its long coastline of 8129 km and an extensive Exclusive Economic Zone of 2.02 million sq km, with an estimated fishery resources potential of 3.9 million tonnes (Anon, 2000), the importance of the marine fisheries sector in the national economy, food security and employment generation need not be overemphasised. In the 3651 fishing villages situated along the coastline, about one million people are employed full time in marine capture fisheries. The fish ing sector dominated by small scale and semi industrial operations, support several ancillary industries such as boat building yards, processing plants etc (Devaraj and Vivekanandan, 1999). Marine fisheries operations have grown from a subsistence level carried out almost exclusively by the traditional fishermen in the preindependence days, to that of a capital-intensive industry requiring close monitoring and management for their sustainability. In the course of the past over five decades of independence, the average annual marine fish production increased from six lakh tonnes in the fifties to the current level of 2.72 mt in 2000. The mechanisation of indigenous artisanal fishing craft and the introduction of modern gear materials during the fifties, introduction of synthetic gear materials during the sixties, advent of purse seining and the motorisation of artisanal craft in the seventies and the substantial growth of motorised artisanal craft operating ring-seines in the eighties were some of the factors contributing to the phenomenal growth of the fisheries sector (Devaraj et al., 1997).
