Abstract

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.

Highlights

Indonesia is the largest aquaculture producer of marine finfish in Southeast Asia [1]
Applying site selection of the SYSMAR DSS shows that Galang Island provides a bright potential for floating net cage (FNC) finfish culture development which is indicated by a suitable area of about 12 940 ha
The findings of this study indicate that the estimation of maximum and minimum production carrying capacity of all potential farms with distances of at least 500 m between farm sites are in the range of (51 to 366) t per farm and (0.5 to 2) t per farm, respectively and estimated production regarding ecological carrying capacity could produce in the range of (18 393 to 21 727) t/yr per community area, respectively

Summary

Introduction

Indonesia is the largest aquaculture producer of marine finfish in Southeast Asia [1]. Being the largest archipelagic state in the world with about 81 000 km of coastline, corresponding to approximately 14 % of the world's coastlines, Indonesia has a great potential for developing the aquaculture industry [2]. The expansion of the aquaculture and fishery sector is expected to improve the country's welfare, especially for fishermen and fish farmers that are currently living under the poverty level. The degradation of coastal environments, overlapping and conflicting utilization of the coastal areas and enforcement of laws regarding the management of the marine and coastal environments are not being addressed properly. It is essential to improve aquaculture technology and to expand management tools that address the need for an ecofriendly production [3]
