Aquaponics is not a new technology including a wide variety of systems, but the interest has grown rapidly in recent years, especially in developing countries. Each system has different types and levels of costs and interest. Aquaponics can be implemented using low-cost materials making it more attractive farmers to diversify their incomes. This article examined the profitability of applied aquaponics in thoroughly reused, recycle local materials and the local species. Three sources of data were considered for the study: (1) commercial local species farms, (2) applied aquaponics farms and (3) published research. The first analysis compares the economics of local farms, traditional aquaponics and applied aquaponics systems under similar operations. Results suggest that the traditional aquaponics system requires higher investment and operating cost compared with the applied aquaponics system and local farms. The second analysis constructed on the aquaponics production of fish and plants as well as the returns. The study found that at the small scale of 1-year operation, applied aquaponics is the most profitable model ($1991.34) at 36 percentage of interest. It is more advantage to develop the economic, social by building environmental sustainability of agriculture to maximize food production through applied aquaponics. The economic efficiency of applied aquaponics in using multiple use of resources, primarily water and nutrients, and recycle certain infrastructural, management and labor costs will keep the aquaponics lasting and expanding to social life.
