Marine living resources are not infinite. Overexploitation is a pervasive problem in fishery the world over. Landings of major fisheries resources in the Indian Ocean region have declined significantly, and the Goan coast is no exception. In many cases, the rate of harvesting has exceeded the natural rate of renewal, resulting in biological overfishing. Such overexploitation leads to stock collapse or severe depletion. This paper documents overexploitation of fishery resources, with particular reference to Goa. Fish production in Goa has significantly increased from 17 000 tonnes in 1963 to a maximum of 102 922 tonnes in 1993 due to mechanization. The analysis of data suggests that catches have exceeded maximum sustainable yield, resulting in negative growth in subsequent years. The rich fish diversity of the Goan coast is boosted by high landing of penacid prawns. The estuaries of Goa are a rich source of different species of prawns (13 species). The occurrence of solar prawns in tonnes for a short period during July-August is an important feature of the Goan coast. High demand coupled with the fact that too many people are dependent on these resources have led to overexploitation. Sustainable development in fisheries requires careful consideration of physical reforms such as resource rent from which economic benefits can be derived in the form of value-added local employment, income, and food security, although these are highly location specific. Opportunities exist to review progress in fisheries management and to exchange ideas on sustainable development through resolute policy decision on a long-term basis.
