10 - Decision tool for assessing marine finfish aquaculture sites in Southeast Asia

Abstract

This chapter summarizes the development of a decision support system (DSS) for spatial planning of marine finfish aquaculture sites in Southeast Asia. The DSS implements methods for site selection and estimation of carrying capacities. These methods are based primarily on results of dynamic models supplemented with in situ measurements and remote sensing information. They follow the FAO's Ecosystem Approach to Aquaculture for ensuring the proper planning and operation of aquaculture sites. In this study, the effectiveness of the DSS is demonstrated for a target aquaculture site in the northwest of Bali in Indonesia. Results of the study led to recommendations for relocation of farms to suitable areas and for reduction of fish production in farms operating above carrying capacity. Recommendations to increase fish production while ensuring sustainable ecological operation in the site were made. The DSS has broad applicability and will help to make decisions for aquaculture sites around the world.
