No results found.. Present state. It can be said that the engineering aspect of brackish water aquaculture industry in the region has attained a level commensurate with the present capabilities of the countries where it is now practiced. In general, as a physical unit, existing projects are hardly adequate. Aquaculture farm engineering as an art (as perhaps at this stage it is more of an art than a technology) has been a product of long development and experience by the people in the industry themselves or witho ut the contribution from organized research. It is only within very recent years that a limited amount of attention is being called to the importance of this phase of the industry. 2. Manpower and equipment. Due to the circumstances cited above the industry has not been utilizing much of labour-saving or mechanized equipment both for operation and construction. At present the industry is largely labour-intensive and depends on simple locally-devised equipment which have been developed through the years. Likewise the specialized manpower for construction and maintenance is localized and often very limited so that in many potential focal points of development this can be a major constraint. 3. Projects as engineering units. The physical make-up of brackish water aquaculture projects in the region are in general weak and inadequate as engineering structures, many of them are not geared to the production management for which they are established. For extensive type production in many d eveloping areas of the region, present projects have served for the conduct of subsistence level operation where constant maintenance is being carried out. However, to maximize production; project design, proper layout and adequate construction specifications, etc. are required. -

Also available in:
No results found.The early drilling of a well at the present Centre, about 30 cm in diameter, or larger if practicable, and up to 150 metres in depth is recommended as an interim measure to effect an urgently needed improvement in dependable water supply at the Centre. If the target yield of 11 liters/second, or more, is realized and water quality is satisfactory, then an appropriate size pump should be selected based on drawdown tests. The pump would be powered by electric power from the City of Sukabumi with s tandby power provided at the Centre. Relocation of the Centre to the upper foothill locations of Mt. Pangrano characterized by the Halimun Valley and Batukarat locations is strongly recommended for more detail engineering study. Sites with the desired 200 liters/second capacity appear available with minimum impact on existing paddy irrigation. Alternatively the survey could also look into the possibility of using other existing Directorate General Fisheries freshwater projects outside Sukabumi . Pipeline diversion of an upland flow to the Centre, which has been previously considered is not recommended because of adverse social and economic impacts on existing rice farms. The possibility of FAO/UNDP assistance with various elements of implementing a new water supply and improving the Centre should be considered in the 1978 IPF as a preproject activity of the proposed Fisheries Extension Project 1979–1982. The estimated UNDP requirement in 1978 is $70,000, as indicated in ANNEX 3. T he corresponding counterpart funding to cover drilling of a well, installation of pumps and motor, and comprehensive site surveys should be provided. -

Also available in:
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.
