| ABSTRACT |
Tropical Recirculating Aquaculture System (TRAS) was developed for commercial inland marine fish production in tropics. The technology is made by integration of local naturally ventilated building structure and recirculating aquaculture system. Building structure protects fish growing up against solar radiation, rain, wind, pests, insects and diseases, while natural ventilation exchanges air, reduces temperature and humidity of in-house aerial environment. Building structure is made of galvanized steel tube frames, metal deck sheet with aluminium sheet roofing and polyethylene insect-screen side cladding. The building generates air temperature and humidity between 25-30oC and 60-80 % respectively. Natural Ventilation controls temperature and humidity at no cost in controlling building environmental cooling.
TRAS consists of circular fiber glass tanks, suction pump, bead filter, ultra violet sterilizer, oxygen saturator and seawater supply. Recirculating Aquaculture System simulates conducive marine fish ecological habitat that enabling commercial inland marine fish production in tropics. Naturally Ventilated Building Structure and Tropical Recirculating Aquaculture System also enabling high yield and premium quality all year round inland marine fish production. The system minimizes risks against, water pollution, insects and diseases as compared to conventional sea cage or open earth pond production. It is green technology, modern, sustainable and environmental friendly marine fish production system.
