    • Aquaculture in Vietnam 

      Nguyen, Xuan Ly. (Aquaculture Department, Southeast Asian Fisheries Development Center, 1995)
      Aquaculture in Vietnam has gained momentum and now produces 370,000 tons of various aquatic commodities. Aquaculture includes shrimp culture in the Mekong Delta; fish culture in cages in rivers, reservoirs, and coastal waters; fish culture in ponds and lakes; mollusk culture in the northern provinces, culture of soft-shell turtle in some provinces, culture of the seaweed Gracilaria. In north and central Vietnam, aquaculture has increased the protein supply, the foreign exchange earnings, employment opportunities, and the living conditions of the people. Vietnam aims to develop aquaculture to produce more than 600,000 tons of aquatic products by the year 2000.

    • Brackishwater integrated farming systems in Southeast Asia 

      De la Cruz, Catalino R. (Aquaculture Department, Southeast Asian Fisheries Development Center, 1995)
      Integrated aquaculture-agriculture systems are more common in fresh water than in brackish water. Nevertheless, southeast Asian countries already have considerable research and experience in brackishwater integrated farming systems. In the Philippines, the effects of animal wastes on water quality and production of fish have been studied: chicken wastes on the mixed culture of milkfish Chanos chanos, tilapia Oreochromis niloticus, and shrimp Penaeus indicus; chicken and cattle manures on P. monodon and Artemia; and swine wastes on tilapia O. mossambicus. In Indonesia, about 60 hectares of fish farms have crops (pumpkin, spinach, cassava, maize, and chili) or livestock (cattle, goat, sheep, chicken, and duck) grown on the dikes of milkfish ponds. In Vietnam, culture of the giant prawn Macrobrachium rosenbergii, Scylla serrata and marine shrimps has been integrated with coastal rice farming. Aquaculture-silviculture is a flourishing venture in Vietnam and Indonesia and gaining ground with experimental sites in Thailand and the Philippines. The seaweed Gracilaria has been cultured with fishes and shrimps in Taiwan, Vietnam, Thailand, and the Philippines. The production of Artemia cysts and biomass has been integrated with salt-making and fish or shrimp farming in the Philippines and Thailand. Production inputs and outputs from these integrated farming systems vary widely and socioeconomic information is nil. It is imperative to conduct follow-up research and evaluation of each system in terms of production and socioeconomics.
