No results found.The report describes the situations and problems related to water quality at marine, brackish and freshwater sites in Indonesia, the Philippines and Malaysia. The Consultant investigated each site and where possible, demonstrated the use of the SWS system, using box units and steel screen wells. The results of each test are given along with detailed advice on the installation and maintenance of permanent systems. Further technical data is supplied in the Appendices along with general description s of the equipment and its applications. The format of the report is as follows: After a brief itinerary, there is a day-by-day account of the stations visited, specific problems discussed and practical work undertaken. For each of the territories, there is a comment on the general application of sub-sand abstraction and filtration principles and on factors which affect them. A series of Appendices lists detailed procedures suggested for solving the various problems. These are treated in t his way so that copies of relevant sheets can be forwarded to individual stations for action. It is hoped that the officials dealing with these problems will write for further advice if this would be helpful. -

No results found.The participating countries of the South China Sea Fisheries Development and Coordinating Programme, including Hong Kong, Indonesia, Khmer, Malaysia, the Philippines, Singapore, Thailand and Vietnam, have a long-standing tradition of fairly common coastal aquaculture practices, due largely to related socio-cultural characteristics, similar climatic and land-sea resources, and the prevaience in the area of the same or related species of fishery resources suitable for culture. 2. Altogether the developed aquaculture areas in these countries are estimated at 430 000 hectares, producing annually about 200 000 tons of finfish and shrimps, 10 000 tons of shrimps and prawns, and 30 000 tons of cockles, oysters, mussels and others. 3. Since the management method in this area is generally extensive rearing of fish in ponds and pens or cages, and in open water for molluscs and seaweeds, production is low; the annual yields are about 500 kg/ha for finfish and 350 for shrimps and prawns.
