    Seaweed utilization as food has a long history in Eastern Asia, particularly in countries such as China, North Korea and South Korea. The importance of these marine plants as a source of nutrients and as components to numerous consumer and industrial products has become increasingly important within the last few decades. Seaweed collection from natural fisheries has been carried out for a long time, however intensive aquaculture is relatively recent history. The seaweed aquaculture sector ha s not developed uniformly in the Asian region. Countries such as China and South Korea have developed sophisticated culture techniques being able to control the entire life cycle of a number of commercially important algae species. In contrast, other Asian countries relay mainly on vegetative propagation such as for Eucheuma in the Philippines. The importance of seaweed output from aquaculture practices is clearly visible from Table 1 and Table 2. Table 1 shows the total production of seaweeds b y species in the Republic of Korea from 1980 to 1986, while Table 2 shows the production derived from aquaculture practices. In 1986 the sea mustard (Undaria pinatifida) production output was 354,661 MT of which over 97 % (346,434 MT) was from aquaculture output. Similarly, almost 100 % of the laver produced (Porphyra spp.) was derived from aquaculture. A great variety of seaweeds are cultured in the region and the total annual production output accounts for a major portion of all maricultured species. Figure 1 shows the aquaculture production in Asia in 1985 by major resource group. Seaweed accounted for 34 % of the year's total aquaculture production next only to finfish which accounted for 44 %. The species of commercial importance vary according to geographical location.

    Upon the request of the Government of Indonesia, a short-term technical assistance on seaweed farming was rendered. The authors gathered available background information and field work led by the senior author was conducted in four selected provinces in the country in April 1980. Nine sites were surveyed, three of which were identified as suitable sites for pilot demonstration of seaweed farming. A programme of development of these farms and the facilities and training needs required are describ ed. A draft proposal for technical assistance project in this type of seafarming is appended.
