-Aquaponics is an evolving closed-system food production technology that integrates recirculating aquaculture with hydroponics. In this paper we give a brief literature overview of the sustainability aspects of aquaponics by discussing its social, environmental, and economic impacts in different potential settings. The technology might be applied to commercial or community based urban food production, industrial scale production in rural areas, small scale farming in developing countries or as systems for education and decoration inside buildings. We conclude that due to the different potential applications and settings for installing the technology, sustainability impacts need to be considered separately and that due the complexity within markets, value chains, communities, urban and rural infrastructure and policy settings, further research and data acquisition is needed to be able to assess all sustainability aspects.

“…Vegetables are candidate plants for use in recirculating hydroponic systems as they grow rapidly in response to the high levels of nutrients in aquaculture water. Different species of vegetables such as ice-lettuce, tomatoes, leaf lettuce, and basil have been successfully grown in aquaculture wastewater (Naegel, 1977;Quillere et al, 1995;McMurtry et al, 1997;Rakocy et al, 2006). Now, there is a strong need for establishing a technology which allows for the efficient cultivation of these food groups while conserving freshwater and land resources.…”

Experiment with varied water circulation periods having 4, 8, 12, and 24 hrs/day as T1, T2, T3 and T4, respectively in aquaponics, evaluated against a control (without aquaponics) revealed higher fish and plant growth in T3 and T4. The mean growth of fish varied significantly among treatments showing higher growth in T4 and control followed by T3, T2 and T1. Survival rate was 100% in all the treatments as well as control. Percentage weight gain, SGR (% day -1 ) also showed the similar trend as that of growth showing T4 as better treatment immediately followed by T3 then T2 and T1. The system maintained favourable water quality throughout the experiment. The growth in T3 and T4 did not vary significantly and was higher than the T1, T2 and control. Also percentage length gain at the end of the trial was maximum in T3 and T4. The Chl (a+b) content in the control was higher than all the treatments whereas, T4 showed the maximum concentration among treatments followed by T3, T2 and then T1. Comparison of all the growth attributes and water quality parameters indicated that water circulation can be reduced to 12 hrs/day for economically effective aquaponics and can be considered as optimum water circulation period for goldfish production in aquaponic system.

“…A major challenge for RASs is the accumulation of nitrogen compounds, which are potentially toxic to fish. A number of investigators experimented with the soilless culture of plants as a fish waste treatment solution for the removal of nitrogen compounds, marking the beginning of aquaponics as we recognize it today [248][249][250][251][252][253]. Since this research was conducted, engineers have developed biofilters that do not rely on plants, however, aquaponic systems improve water quality while producing an additional, potentially profitable crop, distinguishing it from other forms of RAS [91,220].…”

Abstract:The demand for seafood products on the global market is rising, particularly in Asia, as affluence and appreciation of the health benefits of seafood increase. This is coupled with a capture fishery that, at best, is set for stagnation and, at worst, significant collapse. Global aquaculture is the fastest growing sector of the food industry and currently accounts for approximately 45.6% of the world's fish consumption. However, the rapid development of extensive and semi-extensive systems, particularly intensive marine-fed aquaculture, has resulted in worldwide concern about the potential environmental, economic, and social impacts of such systems. In recent years, there has been a significant amount of research conducted on the development of sustainable saltwater-based food production systems through mechanical (e.g., recirculatory aquaculture (RAS) systems) methods and ecosystem-based approaches (e.g., integrated multi-trophic aquaculture (IMTA)). This review article will examine the potential negative impacts of monocultural saltwater aquaculture operations and review established (RAS) and novel (IMTA; constructed wetlands; saltwater aquaponics) saltwater-based food production systems and discuss their (potential) contribution to the development of sustainable and environmentally-friendly systems.
