Economic valuation of coastal ecosystems is essential for environmental planning and management, which ultimately leads to sensible use of coastal resources and services. Karnataka is one of the major maritime states on the south west coast of India. In this research, an attempt was made to understand the biodiversity and the economic value of coastal ecosystems of Karnataka to highlight its Provisional Services, Regulatory Services, Supporting Service and Cultural/spiritual services for biodiversity conservation and management.

Excerpts from the Article 8 of the Convention on Biological Diversity: In situ conservation, which promote the protection of ecosystem and the maintenance of viable populations of species in natural surroundings. In India we had several species of organisms belonging to different groups constitute the protected marine organism and majority of them are belonging to elasmobranchs, dolphins, whales, sea cow, turtles, molluscs, corals, sponges holothurians and gorgonids. India is blessed with rich biodiversity along the west and east coast resulting in the supply of essential ecosystem goods and services to the millions of population living in the coastal area.

Diversity observed from filter feeders, herbivore to highly carnivorous groups. Fish culture habitats also showed the diversity from estuary, lakes, mangroves, coastline, inshore to offshore areas. Two major subsectors emerged in the aquaculture sector are the family and co-operative farms mainly follow the extensive and semi-intensive practices, whereas the commercial farms follow the intensive and semi-intensive practices to produce high valued products for the global market. The aquaculture production can reduce the pressure on the capture production and can lower the investment in the fishing fleets and effort.

Modern scientific studies on Indian fishes could be traced to the initial works done by Linnaeus in 1758. M. E.

The situation calls for urgent measures to sustain the production close to the target potential yield of 4.41 million tonnes. These measures would mean implementation of science based fisheries management and regulations. Although much has been accomplished by way of research and development in marine fisheries in India, the transformation and implementation of the outcome of these studies into effective management of marine fisheries resources of the country has been a shortcoming so far. The FAO brought out the Code of Conduct for Responsible Fisheries (FAO-CCRF) in 1995 to serve as a guidance for countries for a sound and effective management of fisheries resources. This FAO-CCRF has not been put into practice in India, al...
