The Benefit of Decision Support System as Sustainable Environment Technology to Utilize Coastal Abundant Resources in Indonesia

Being the largest archipelagic state in the world (± 81 000 km of coastline), Indonesia has a great potential for developing the aquaculture industry. But, the accomplishment of sustainable practices and management systems are still in its infancy. Therefore, it is vital to improve aquaculture technology and develop management tools that address the need for an eco-friendly production process. In this manuscript, the Decision Support System software is applied for the management of sustainable floating net cage finfish cultures. This software integrates physical, chemical, biological properties and information on coastal uses to determine site selection, production carrying capacity, ecological carrying capacity and socio-economic assessment of 18 cases, focusing on the economic viability of Tiger grouper [Epinephelus fuscoguttatus (Forsskål, 1775)], Humpback grouper [Cromoliptes altivelis (Valenciennes, 1828)] and Leopard Coral grouper [Plectropomeus leopardus (Lacepède, 1802)] at three remote areas in Indonesia, including: Ekas Bay, Talise and Galang Island. The outcomes demonstrate that only Galang Island provides a suitable area of 12 940 ha with the estimated production carrying capacity of (0.5 to 366) t/annual per fish farm along with ecological carrying capacity are limited of (18 393 to 21 727) t/annual and economic evaluation highlighted that all cultures development are economically viable
