Most of the marine fish landings from the Indian waters are from the fishing operations in the coastal shelf area, especially from the shallower region ranging from 5 to 100 m depth. Heavy demand for seafood in domestic and international markets underlines the need for increasing the marine fish production. Catch trends indicated that the production from the coastal fisheries is almost stagnant and point towards the need for harvesting unexploited or under exploited oceanic fish resources. Present fleet size of the distant water fishing vessels is very less in spite of India’s vast EEZ of 2.02 million sq km and two Islands groups, viz., Andaman, Nicobar and Lakshadweep. ... Experimental longline operations were initiated in the Lakshadweep Sea to tap the unexploited oceanic tuna fishes. This paper discusses the effect of depth of operation and soaking time on the overall catching performance and species selectivity in the longlines operated.
