         •  No  arable  land  required:  Systems
        can be built near urban areas, close
        to the market.
         • Low running costs: After the initial
        setup, operational costs are relatively
        low. The main input is fish feed, which
        can  be  partially  replaced  by  culti-
        vating  duckweed  within  the  system.
        Costs and income are predictable.
         •  Climate  adaptable:  Greenhouse
        structures can be tailored for any cli-
        mate,  from  desert  heat  to  cool  high-
        lands.
