No results found.This paper describes the nutrient dynamics in selected inland waters used for aquaculture. It is based on field work in the Philippines, Thailand and Hong Kong during October/November 1975. Seasonal fishkills resulting in economic losses, were analysed. Based on the field work and available literature pertinent to the subject, proposals for monitoring programmes aimed at predicting fishkills in the areas visited were formulated. -

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. -
