      Mitigation plan on the use of mangroves for aquaculture: Thailand. 

      S Tookwinas - 2004 - Aquaculture Department, Southeast Asian Fisheries Development Center
      Mangrove forest is one of the important coastal natural resources of Thailand, however, mangrove forests have deteriorated very rapidly at a rate of more than 50% of the mangrove loss during 1961–1996. The utilization and destruction of mangrove forest has been seriously discussed in many fora. Shrimp farming is one activity, which has disturbed the mangrove forests. According to the inventory and analysis of LANDSAT5 TM satellite imagery data of 1993, only 17.49% of shrimp farms are located in mangrove forests and only 7.36% in the productive area. In addition 10.10% of shrimp farms are in unproductive or upland area, which have been leased legally by the farmers. Therefore, the Royal Thai Government has been working closely with the local communities and NGOs to implement a mangrove reforestation program targeting a replanting of 24,394.64 ha. As a result, the mangrove area has increased to 252,750.88 ha in 2001.

      Shrimp culture and mangroves: Brunei Darussalam. 

      SHAIbSH Nekman - 2004 - Aquaculture Department, Southeast Asian Fisheries Development Center
      Brunei Darussalam is a coastal state located in the north-western portion of Borneo island within latitudes 5o 05’ N and 4o 00’ N and longitudes 114o 04’ E and 115o 22’ E. The country has a land area of 5765 km2 (576,400 ha.) divided administratively into four districts, i.e. Brunei-Muara, Tutong, Belait and Temburong. The coastline of the country is roughly 130 km long, fronting the South China Sea and shares a common border with the east Malaysian State of Sarawak. The main population centers are in the coastal zone, accounting for over 85% of the population (305,100 in 1996). It is a Malay Islamic Monarchy and has a stable economy largely dependent on the exploitation of petroleum hydrocarbons.

      The use of mangroves for aquaculture: Cambodia. 

      SL Song - 2004 - Aquaculture Department, Southeast Asian Fisheries Development Center
      Natural conditions of the coastal and ecosystems of Cambodia have made this country rich of biodiversity resources. Cambodia’s 435 km coastline is covered with large estuaries with about 85,100 ha of mangrove forests (Nelson 1999). Even the coastline disadvantageously compares to that of other countries of the Southeast China Sea region, but its natural creations such as large and small bays, number of big and small inshore and off-shore islands, sea floor, oceanic current, freshwater rivers and streams, weather etc., support the diversification of all bio-resources. Fortunately, due to the fact that most Cambodians are interested in inland rather than coastal aquaculture, as well as suitable development management and conservation policies of the Government in the past, these natural habitats remained pristine until 1970. However, the habitats have been disturbed because of the various exploitation and development works for several decades during the wartime and even after, due to lack of managerial strategy.

      Cambodia had joined the Biodiversity Convention since February 1994, but until now, due to economic depression and poverty, the national awareness on the importance of biodiversity conservation is very limited. The crowded competition on exploitation of nature including coastal and marine resources, have been very aggressive in recent years that degraded the natural environment faster. Currently, many efforts and attempts by NGOs and international organizations have been made in collaboration with the Ministry of Environment and the Ministry of Agriculture, Forestry and Fisheries, to alleviate the marine and coastal resources pressures.

      Use of mangroves for aquaculture: Myanmar. 

      UT Win - 2004 - Aquaculture Department, Southeast Asian Fisheries Development Center
      Aquaculture has only started to develop rapidly in the past few decades, due to better knowledge of culture species, improved methodologies and techniques in breeding, nutrition and increasing demand for food fish of high-value species such as shrimps, sea bass and groupers.

      Mangrove deforestation has an impact on shrimp culture itself, the success of the latter (when traditional culture method is used) depends on stocking of wild fry. For semi-intensive and intensive shrimp culture, the number of wild caught spawners may decrease because wild shrimp populations also use mangrove swamps as its feeding ground.

      Other negative effects of mangrove destruction to make way to shrimp ponds, include water pollution from pond effluents, sedimentation from the release of solid materials from pond, interruption of the tidal water flow, dwindling natural shrimp and fish stock due to increased pollution or product contamination due to indiscriminate use of chemicals.

      Chemicals and drugs (antibiotic) should not be used in fish and shrimp culture for prevention and control of bacteria and viral diseases. In order to ensure the sustainable development of aquaculture, it is important to bear in mind the interdependence of technology and natural resource under various socioeconomic setting.

      Use of mangroves for aquaculture: Vietnam. 

      NTT Nhung - 2004 - Aquaculture Department, Southeast Asian Fisheries Development Center
      Vietnam has a coastal line of 3600 km with a large wetland (tidal area) area of 600,000 ha (according to the survey statistics of the Institute of Planning and Economics under the Ministry of Fisheries), in which mangrove areas occupy a big part. Before the war, there were about 400,000 ha of mangroves in Vietnam; the largest area located in the South of Vietnam (Mekong River Delta) mainly in Tra Vinh, Soc Trang and Minh Hai. Mangrove forest serves as buffer zone or as biological filter layer. Mangrove is not only a very important ecosystem for forestry and agriculture but plays a decisive role in exploitation, aquaculture and biodiversity yield. Mangrove forests of Vietnam, especially in the South of Vietnam has been the main source of livelihood for farmers and fishermen, for a long time, which until now still occupy a large proportion of the whole country.
