Aquaponics, the combination of aquaculture and hydroponics, can lead to sustainable food production. This study shows how duckweed can add value to an aquaponics system. It builds off of a previous case study that explored the addition of hydroponic grown buttercrunch lettuce to a barramundi fish production system. That case study concluded that the benefits of the integrated system include the reduction in barramundi effluent disposal costs, and saving of water and nutrient costs of the lettuce system. We build off that analysis by adding duckweed to the integrated system, and compare the variable costs and revenue of a production system of barramundi and lettuce, to that of barramundi, lettuce, and duckweed. Duckweed serve as fish feed and a biological filter. The addition of duckweed results in a decrease in feed cost and effluent disposal cost, as well as significantly reduced the area needed to build the integrated system.
