Abstract
Economic development on Indonesia’s numerous small islands faces a number of challenges stemming from the islands’ isolation and resource limitations. Mariculture has been promoted as a viable development strategy in these areas, and this research assesses a marine spatial planning approach to support net-cage grouper mariculture development in waters surrounding Kaledupa Island located southeast of Sulawesi. Data collection focused on 15 biophysical capability parameters, plus an additional 7 suitability parameters assessed through interviews with villagers and local experts. Capability analysis identified 4,511 hectares capable of sustaining grouper mariculture within the 8,582 hectares study area. Suitability analysis identified 2,667 suitable hectares based on villager opinions and 4,083 suitable hectares based on local expert opinions. Reliance on villager opinions and resolution of fragmentation issues reduced the final area deemed suitable to 2,423 hectares. This study highlights the importance of utilizing local ecological knowledge in marine spatial planning, and emphasizes the need for follow-up studies, monitoring and enforcement of environmental regulations to ensure that negative impacts do not emerge in island communities as a result of mariculture development.
