Urban aquaponic in malaysia. aquaponic farming is the combination of the latest aquaculture (raising fish in contained tank) and hydroponics (growing in soil with recirculating water system). water is drained from the fish tank, into a media bed using the gravity force. the theory of aquaponics is to maximize the use of the energy and nutrients.
