Competition and commercialization in marine fisheries have generated discrepancies and imbalances in marine ecology, sustainable production and distributive justice. The private capital investment made on crafts-gears in capture fisheries does not any way compensate the social cost of overexploitation of certain resources, uncontrolled juvenile fishing and discards. The common property nature of marine fisheries coupled with market driven catching strategies and technological changes led to overexploitation of varieties such as elasmobranchs, catfish and goatfish along Kerala coast. However, the analysis of production trends for a period of four decades reveals increasing trends in the landings of species such as oilsardine, anchovies, lizardfish, perches, carangids, tunnies, barracudas, flat fish and cephalapods. The study on the environmental economics of inshore fishery resource utilisation of coastal Kerala has been undertaken in four southern Districts (Ernakulam, Alappuzha, Kollam and Thiruvananthapuram) during the year 2001-2003 with focus on environmental hotspots of industrial pollution and sea erosion along with details of economic loss of juvenile fishing by trawl fisheries.
