Indonesian Aquaculture Development INDONESIAN AQUACULTURE DEVELOPMENT Made L. Nurdjana Director General for Aquaculture, Ministry of Marine Affairs and Fisheries Jl. Harsono RM No. 3, Rangunan, Pasar Mingu Jakarta, Indonesia ABSTRACT This paper describes the status of aquaculture development in Indonesia, and the importance of the subsector as an important component of Indonesian fisheries which contributes to the national food security, income and employment generation, and foreign exchange earnings. The paper also describes government organizations and support services to aquaculture, technological development in fish farm management and production of safe aquaculture foods, and emerging and future challenges face by the aquaculture industry. Operational policy and strategy for aquaculture financing were also discussed, as well as strategies for the future development of aquaculture. Key words: Indonesia, aquaculture, technological development CURRENT SITUATION OF AQUACULTURE The total national aquaculture production in IN THE NATIONAL ECONOMY 2005 was 2.16 million tons. Aquaculture and inland water capture fisheries contributed 29.1 percent to Historical development the country’s total fish production. Total aquaculture of aquaculture in Indonesia production increased by about 20.14 percent per year from 1,076,750 tons in 2001 to 2,163,674 tons Aquaculture is an important component for in 2005 as a result of technological innovation, area Indonesian fisheries as it contributes to national of expansion and availability of suitable quality of food security, income and employment generation, fish seed. Aquaculture is practiced in fresh, brackish and foreign exchange earnings. Aquaculture has and marine waters using a variety of production played its role as an alternative source of income for facilities and methods. Culture systems range from coastal fishery communities. It has also contributed extensive to intensive depending on the seed in reducing the pressure on marine natural resources. stocking density, the level of inputs and the degree Recently, aquaculture development in Indonesia of management.

At the national level, the extent of areas which has a potential for aquaculture Freshwater aquaculture development is estimated at 15.59 million hectares, composed of Freshwater aquaculture started with the stocking of 2.23 million ha of fresh water bodies, 1.22 million ha common carp in backyard ponds in West Java of brackish water areas and 12.14 million ha of during the Dutch occupation, in the middle of the marine areas. To date, only 10.1 percent of 19th century, and subsequently spread out to other freshwater, 40 percent of brackish-water and 0.01 parts of Java, Sumatra and Sulawesi islands in the percent of marine areas potentially suitable for early 20th century.

  • 9. Indonesian Live Reef Fish Industry
    ECONOMICS AND MARKETING OF THE LIVE REEF FISH TRADE IN ASIA–PACIFIC 9. Indonesian live reef fi sh industry: status, problems and possible future direction Sonny Koeshendrajana1 and Tjahjo Tri Hartono1 Background Live reef food fi sh (LRFF) has been traditionally consumed by Chinese people, especially among the southern coastal populations. For centuries, this tradition has existed because fi sh is considered a symbol of prosperity and good fortune in Chinese culture. Yeung (1996) and Cheng (1999) in Chan (2000) pointed out that fresh marine fi sh, especially the high-valued live reef food fi sh, has an important cultural and social role for special occasions, festivals and business dinners. With the rapid growth in population and rise in household income, demand for fresh marine fi sh also increases signifi cantly. This, in turn, leads to imports from many countries, such as the Philippines, Thailand, Australia and Indonesia. With high demand and extremely high prices expected, these marine species are widely exploited. The LRFF trade has been become a global as well as regional concern. Available evidence suggests that LRFF have been over-exploited in many parts of Southeast Asia, such as in the Philippines and Indonesia. An important species of concern is the grouper fi sh, known as ‘Kerapu’. One of the ecological functions of coral reef is as a habitat for fi sh, such as the coral fi sh group. Indonesia has a coral reef area of 85 000 sq. km (about 18% of the world’s coral reef area) and thus has the potential to become one of the main producers of live reef fi sh.

    TRENDS IN MARINE RESOURCES AND FISHERIES MANAGEMENT IN INDONESIA | A 2018 REVIEW 1 Trends in Marine Resources and Fisheries Management in Indonesia A 2018 REVIEW 2 TRENDS IN MARINE RESOURCES AND FISHERIES MANAGEMENT IN INDONESIA | A 2018 REVIEW 01 Executive summary TRENDS IN MARINE RESOURCES AND FISHERIES MANAGEMENT IN INDONESIA | A 2018 REVIEW 3 Executive summary A country bridging two oceans As the world’s largest archipelagic state, the ocean plays an undeniably central role in Indonesia. With a water area that is nearly four times larger than its land area (Fig.1), the country derives pivotal benefits from the sea for its economy, geopolitics, culture, and natural environment. Situated at the center of major maritime trade routes, its seas are a gateway linking Europe, the Middle East, Africa, and South Asia. Its coastal and marine waters make up one of the most fertile fishing grounds in the world: Indonesia is the second largest fish producer in the world, second only to China. Roughly 55 percent of this production comes from coastal areas, particularly from seagrass beds, mangroves, coral reefs, and estuaries. The country has the world’s largest area of mangrove forests which cover about 3 million hectares and contain five times as much carbon per hectare as tropical forests. A global hotspot and priority for conversation, Indonesia has one of the highest levels of marine biodiversity in the world and is home to world-renown marine reserves such as the Bird’s Head Seascape and Sunda Banda Seascape. While these resources present an abundance of natural capital, there are also material challenges in managing them effectively.

  • Aquaculture in Indonesia
    Aquaculture in Indonesia Dedi Yusuf Directorate General of Fisheries Ministry of Agriculture Jakarta, Indonesia Yusuf D. 1995. Aquaculture in Indonesia, pp. 109-115. In: Bagarinao TU, Flores EEC (eds) Towards Sustainable Aquaculture in Southeast Asia and Japan. SEAFDEC Aquaculture Department, lloilo, Philippines. Abstract Indonesia has a long tradition in aquaculture, particularly in fresh water and brackish water. Most aquaculture is still in extensive systems with low productivity. Mariculture only started in the 1980s and contributes yet little to the total national production. Aquaculture has become increasingly important, particularly in supporting rural economies. The development of shrimp and prawn culture became a Government priority after trawl fishing was banned in 1980-81. With its strategic geographic position and enormous inland and coastal resources, Indonesia has good prospects in aquaculture. Introduction Aquaculture in Indonesia is generally small-scale, with low technological inputs and high degree of dependence upon nature. Aquaculture covers freshwater, brackishwater, and marine culture. Freshwater and brackishwater culture have been practised for a long time, but mariculture or Seafarming just started in the early 1980s. More than 470,000 hectares of inland waters and 86,000 hectares of coastal waters are available for aquaculture. The total seed supply from open waters is estimated at 11.3 billion per year, consisting of 1.5 billion of milkfish, 800 million of shrimp, and 9 billion of freshwater fishes. Aquaculture has become important particularly in supporting the rural economy in Indonesia. In 1991, aquaculture made up 617,700 tons (Table 1) of the total fisheries production of 3,186,000 tons (FAO 1991, FAO 1993).

Saut Gurning1, Badrus Zaman1, Semin1 1Department of Marine Engineering, Institut Teknologi Sepuluh Nopember, Surabaya, 6011, Indonesia Keywords: Blue Economy, Coastal Open-Water Modelling, Integrated Multi-Trophic Aquaculture (IMTA). Abstract: Integrated Multi-Trophic Aquaculture IMTA is an environmentally friendly solution and sustainability of aquaculture or aquaculture. IMTA is one form of marine cultivation by utilizing the provision of ecosystem services by low trophic organisms (such as shellfish and seaweed) that are adjusted as mitigation of waste from high trophic level organisms (such as fish). The blue economy is closely related to marine and marine- based sectors, such as the fisheries, transportation and tourism sectors. The survival of marine biota as food ingredients and livelihoods for people around the sea is a blue economic focus to reduce poverty and hunger. Coastal Open-Water modelling of IMTA in Indonesia is very appropriate to be carried out in coastal or coral areas because the area has been damaged due to aquaculture or fishing activities that are not environmentally friendly and environmentally friendly. So that IMTA can be applied on the Indonesian coast with innovation and creativity in order to improve seaweed cultivation that is efficient, environmentally friendly, utilizing other ecosystems that are mutually beneficial, improving the economic welfare of the community, and availability for a long time in accordance with the concept of blue economy. 1 INTRODUCTION the presence of residual food decomposed in the water column which can increase the biochemical Integrated Multi-Trophic Aquaculture (IMTA) is one oxygen demand, increase dissolved phosphate form of marine cultivation by utilizing the provision content and increase dissolved nitrogen content.

Fisheries supplies 23.1 kg of food fish to Asian population in 2013, which comprised 22.9% of animal protein and 7.9% of total protein in food of the people. Meanwhile, Fishing and aquaculture production provided some 48 million jobs directly and millions more employment in related manufacture, processing and service sectors. Marine and inland water ecosystems and aquaculture biodiversity are most important resources and service providers to social and economic development in the region. In order to contribute to the sustainable development goals, capture fisheries and aquaculture sectors have been assigned important tasks to support the food security and improved nutrition and eradication of poverty through realizing blue economic growth ( Sustainable growth of economies derived from marine and inland water ecosystems and living aquatic resources ) with responsible and efficient use of marine and inland water and associated natural resources and conservation of marine and inland water ecosystems and aquatic biodiversity. Given the global leading position of Asian fisheries in production and direct dependence on the sector, the Asia and Pacific Region will need to take a leading role in achieving the goal considering its current share in global fish production and trends of the sectoral development in the different regions.

The area that can potentially be used for aquaculture development is of 26 606 000 ha. Aquaculture plays an important role in reducing unemployment. In 2003 there were 2 284 208 households involved in the aquaculture industry, representing around 40 percent of the total number of people employed in the fisheries sector. Aquaculture in Indonesia is practiced in fresh, brackish and marine water using a variety of species, production facilities and methods. Freshwater aquaculture began to develop in the late 1970s when there was a significant increase in production from freshwater aquaculture as a result of the introduction of new farming technologies which contributed to the availability of hatchery-produced seed and the development of compound feed. The most common aquaculture species are common carp (Cyprinus carpio ), catfish (Clarias spp., Pangasius spp.) and Nile tilapia (Oreochromis niloticus ).

  • Public Policy for Sustainable Development of Grouper Aquaculture in Indonesia
    PUBLIC POLICY FOR SUSTAINABLE DEVELOPMENT OF GROUPER AQUACULTURE IN INDONESIA Prof Ketut Sugama Directorate of Seed Development Directorate General of Aquaculture Indonesia Jl. R.M Harsono No 3. DEPTAN Gdg-B, Lt.5. Ragunan, Jakarta, 12550 Indonesia [email protected] SUMMARY The Policy of the Department of Marine Affairs and Fisheries of Indonesia is to control the production of fish from capture fisheries and to increase fish production from aquaculture in terms of both quantity and quality for domestic consumption and export. At the end of2008, the total value of foreign exchange from aquaculture was expected to be US$ 2.7 billion. One of the important government policies is to establish aquaculture integrated zones. Following the basic concept of zoning, there are five programs for developing aquaculture: (1) Aquaculture intensification program (2) Rural aquaculture development program (3) Integrated aquaculture development program (4) Culture base fisheries program and (5) Low input aquaculture. During the last two decades, Indonesian aquaculture has developed rapidly due to the combined efforts of aquafarmers, investors, and experts from universities and research institutes. Although aquaculture has contributed greatly to the fisheries production and its value, the Indonesian aquaculture sector is still facing many constraints. Sustainable development of Indonesian aquaculture is affected by constraints in policy, resources, institutions, socio-economic factors, technology and finance. In this paper, these constraints are briefly reviewed and opportunities for further development for Indonesian Aquaculture are discussed. The paper also deals with the need for a specific policy for sustainable development of grouper aquaculture. These policies would encompass, seed, feed, investment, environment, technology and trade.
