I've already done some activist work with our State Governor and representatives to promote aquaponics (growing fish, vegatables, frutis) and have been in training learning what is needed to set up a commerical system. However, what really needs to happen is to down scale this system to a family model that can easily fit in one's back yard or flat roof top for city areas.
These self-contained units are designed to circulate and clean the fish poop out of the water so that it goes back into the fish tank. The fruit and vegetables from these systems are incredibly nutritious and taste wonderful due to the roots being exposed to the fishes excrement. The roots act as a biomass filter for the water to pass through before being pumped back into the fish tank (comercial system tank is made out of plywood and is 12' by 12'. The plywood is treated with a fiber glass coating so as to preserve the wood. The water beds on the commercial system are 30 feet long 2 feet wide and 12 inches deep.
The two primary problems with this system is keeping the fish alive and the electricity needed to run the water pumps and airiaters for the fish. If the electricity were to stop, one could lose their fish in a matter of hours so electricity is a real concern. Solar is expensive and wind works when there is wind.. so this situation has to be handled correctly to have a successfull aquaponics system.
