520			_aKoh Kong province is famous for its abundance in production of fisheries, particularly molluscs' species, because it has the largest productive estuarine area among the coastal provinces in Cambodia. However, in recent years the fisheries production has been declining drastically because of overfishing and destmction of mangrove forests, and there is an immediate need to develop the coastal aquaculture systems reducing the strong dependence on capture fisheries resources. In response this need, coastal aquaculture has developed in the past several years, especially shrimp farming, but this aquaculture system was not financially and environmentally acceptable. This study was subdivided into two parts. The first part was concentrated on reviewing the coastal natural resources; and government policy, laws, regulations and development plans relevant to coastal aquaculture. The second part was based on the analysis of primary data collected from existing aquafarmers. From this information the study aims to make a preliminary identification of the potential of the most appropriate aquaculture systems, which can be afforded by many coastal poor fishermen; from ecological, technical, institutional and socioeconomic perspectives. There are three aquaculture systems operating in the province. The most rapidly developed is the shrimp industry, although shrimp farming is experiencing severe losses because of disease prevalence. Grouper culture is being developed and established on the abandoned shrimp ponds, stocked with wild fingerlings caught from the nearby estuarine areas. Green mussel culture is also being practiced by fishermen and production has increased year to year since its start in around 1993 with the total production of 450 MT and 1,000 MT in 1998. Results from a narrow financial analysis show that green mussel culture is profitable and can generate an average net profit of 13 Baht per pole (60,087 Baht per farm per year). Grouper farming is seen as moderately profitable, generating an average net profit of 45,573 Baht per hectare per year provided that harvested products have an access to the market. By contrast, shrimp culture generates a negative return to investment, losing about 110,032 Baht per hectare per year. Sensitivity analysis points out that the shrimp farming is only likely to be profitable when the sale price increases by 20 percent, or when the production increases by 20 percent, provided that management skills, culturing techniques and pond preparation practices are improved and satisfactorily upgraded. Recently, government policy has begun to address the development of coastal aquaculture. An attempt has been made to establish a marine research institute based in Sihanoukville. From this positive initiative, the Department of Fisheries in collaboration with non governmental agencies and private sectors should immediately synthesize their development plans and provide as much assistance as possible in an attempt to diversify coastal aquaculture systems suitable to poor coastal inhabitants, but the development should proceed in a framework of social and environmental sustainability.
