The aim of the seawater irrigation system (SIS) is to clean up shrimp pond effluent and provide high quality seawater for shrimp farming. The system has 3 components: water intake; treatment reservoir and discharge system. There are criteria for site selection because shrimp farmers are required to form associations so they can work closely together. The construction site must be on the coastal area outside a mangrove forest and located away from a production agricultural area. All construction sites must have undergone an environmental impact assessment, and should be located on the area listed in Thailand's Coastal Zone Management Plan. Five SIS projects, which cover a culture area of 6,500 ha with 1,300 farmers (families), were completed and operated. The Department of Fisheries has planned for another 28 projects, that will cover almost 44,000 ha of culture area.

Although fish culture itself is an age-old tradition in Taiwan, it was in the 1960s that the first successes on artificial propagation were achieved, with several species of Chinese carps and tilapias. The first marine fish to be bred in captivity was the grey mullet; it was first induced to spawn in 1968. Various other species have since been added to the list of propagated marine fish. The characteristics of the marine fish hatchery industry in Taiwan are outlined, considering both the outdoor pond and indoor tank systems. Future prospects are very good; Taiwan now exports marine fish larvae and fingerlings to many of its Asian neighbours and there are some 60 marine fish species for which commercial larval production is possible.
