System design In the first year of the project three 3 households were chosen for demonstration purposes. These three households were chosen based on various selection criteria which were unique and representative of the local area. The main features of these three demonstration households were limited land high nutrients discharged from animal production system pigs mainly into the existing water bodies and willingness of the households to adapt new technologies and extend them to other households. One demonstration household was located in Nghe An Quynh Luu and other two in Quang Tri Trieu Hoa and Trieu Lang . The new technology incorporated introduction of a new high-value specie and establishment of a new water recirculating culture system which is expected to have no discharge into the existing water body pond . The discharge waste from the new recirculating system is planned to be used in the production of earth worms which in turn can be fed to fish and used for horticulture purposes. The water recirculating VAC fish production system at each household consisted of one culture tank with biofiltration and waste collection tanks and an associated earth worm house. The proposed design for each component of the system is shown in Figures 1 - 4. 2 HOUSE FOR CULTURE TANK Unit mm Waste tank Waste treated tank - 12 concreted columns. - Brkk for tank -Dimension 12 volume 15m3 Support roof by bamboo roof with CO leaves and surrounding with bamboo. - House area 50. - Filter tank by brick m - Volume 4 parts -Bio -filterby plastk 3500 -1 3600 3600 -D- 3600 1 3600 1 Figure 1
