The present study identifies existing mariculture activities and its constraints in SE Sulawesi, along with its geo-physical attributes in the Province.This allows for a better understanding the potential, current and future status of mariculture development in the area and making sure its sustainability. The study was conducted to map the existing mariculture activities in SE Sulawesi. Data collection was performed in June 2009. Spatial and attribute data of the existing mariculture were acquired by interviewing fish farmer using open-ended questionnaire and analyzed using ArcGIS 9.x. Key water quality parameters consisted of temperature, dissolved oxygen, pH, salinity, depth, clarity, and turbidity and analyzed using STORET Indeks. Three big clusters of existing mariculture activities are located in Kendari, Muna and Buton areas, collectively serving as both a source of mariculture products and a market destination or transit location. All surveyed locations of existing mariculture activities in SE Sulawesi show relatively optimal water quality conditions. Site capacity and suitability analysis of existing or potential areas of mariculture activities and development have largely not been considered by stakeholders involved in managing coastal areas, resulting in crowded and unmanaged development with multiple overlapping economic activities in some areas. Piloting of integrated ‘value-adding’ mariculture industries (e.g. raw material, processed products and ‘ready to eat’ industries) might help ease some if not all of the existing economic problems of the mariculture sector.
Rumput laut merupakan komoditas unggulan ekspor perikanan budidaya di Indonesia. Untuk mempertahankan ataupun meningkatkan produksinya dapat dilakukan melalui perluasan areal budidaya. Pemilihan lokasi yang sesuai merupakan tahapan awal untuk mendukung keberhasilan usaha budidaya rumput laut. Penelitian ini bertujuan untuk melakukan analisis kelayakan lahan untuk budidaya rumput laut dengan metode apung di kawasan minapolitan Kabupaten Bintan. Data kualitas perairan telah dikumpulkan saat survai lapangan bulan Juli 2010. ALOS AVNIR-2 digunakan untuk mengekstrak data sosial infrastruktur. Data kualitas perairan dan sosial infrastruktur kemudian dianalisis secara spasial dengan sistem informasi geografis dan multi criteria analysis. Hasil analisis spasial menunjukkan bahwa dari total potensial pengembangan (904 km2), sekitar 13% tergolong sangat layak untuk pengembangan budidaya rumput laut. Lokasi dengan kategori sangat layak terkonsentrasi di Pulau Mantang, Telang Kecil, Gin Besar, Numbing, Gin Kecil, Buton, Poto, dan Kelong. Hasil penelitian ini sangat relevan dengan penetapan Kabupaten Bintan, meliputi: Kecamatan Bintan Timur, Mantang, dan Bintan Pesisir, sebagai kawasan sentra pengembangan minapolitan.
Aquaculture, particularly marine‐based production, is one of the fastest growing industries in Indonesia. Indonesia's competitiveness in the trade of aquaculture products is constrained by a lack of research and development (R&D) of new aquaculture species candidates. Mariculture has the greatest potential due to Indonesia's vast marine resources and archipelagic geography. Although there are over 3,000 species of marine fish in Indonesia, only 14 species have been widely cultured, largely finfish. Production is dominated by shrimp, groupers and milkfish. Traditionally, candidate species for mariculture in Indonesia and elsewhere have often been selected on their market value before their biological suitability for culture has been established leading to partially successful R&D efforts or even failure. The present study developed a framework for selecting marine fish species to support mariculture R&D in Indonesia based on an improved analytic hierarchy process (AHP). The approach combined various quantitative and qualitative data and involved different R&D stakeholder groups in the selection process. Ten species that had not been previously researched for their aquaculture potential were identified. The modified approach addressed the interaction complexity of criteria and different preferences across the stakeholders. The involvement of different stakeholders in the selection process not only ensured acceptance of the selected species for further research, but also tested the validity and consistency of the method used in this study. The methodology has relevance for mariculture globally given that efficient candidate selection can help focus efforts and investment in mariculture R&D.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
