Abstract
Artificial fish production is one of the important food supply system in the world. On the other hand, aquaculture has been a pollutant source of natural water environment in no small part. This explanation introduces closed recirculating fish culture system which is expected to develop the aquaculture technology and improve economy further. The system has a lot of advantages including environmental conservation and food safety compared with other aquaculture systems. Furthermore closed ecological recirculating aquaculture system using artificial food chains is explained for the futural situation of aquaculture in space as the derivative technology with our accumulated knowledge on the management of the artificial food chain, rearing systems and postural control mechanism of aquatic animals under various gravity environments. Finally, the direction of future perspective for aquaculture function, technology and economics is discussed from the aspect of eco-engineering.
