“…Aquaponics production system is therefore considered one of the most efficient and environmentally sustainable farming methods of the twenty‐first century (FAO, 2014; Oladimeji, Olufeagba, Ayuba, Solomon, & Okomoda, 2020) as it combined the RAS with hydroponic system, hence mitigating the adverse effects of these methods on the environment (Tyson, Treadwell, & Simonne, 2011; Zou, Hu, Zhang, Guimbaud, et al, 2016). This integration ensures that the nitrogen‐rich fish wastes produced are utilized as organic fertilizer by the plant (Blidariu & Grozea, 2011; Love et al, 2015; Pantanella et al, 2010), while the purified wastewater recycled from the plant is used in rearing the fish (Zou, Hu, Zhang, Xie, et al, 2016).…”

Aquaponics is known to be a smart way of producing fish and crops simultaneously; however, there is a paucity of information about the extents of this system's efficiency over other conventional methods of food production. Thus, this study was designed to evaluate the performance of a catfish–pumpkin aquaponics system in comparison with recirculatory and static aquaculture systems (for fish performance), as well as irrigated and nonirrigated systems (for pumpkin performance). Results obtained showed that the production of fish in the aquaponics system was 29% and 75% more efficient than recirculatory and static aquaculture systems, respectively. The survival of the fish was also significantly improved probably due to better water quality in the aquaponics system. With respect to pumpkin production, yield in the aquaponics system was about five times the performance in irrigated land and eleven times those in nonirrigated land. This study gives definitive evidence to support the efficiency of the aquaponics system over other conventional food production methods.

“…The pak choi humidity was also similar to the value reported by the US Department of Agriculture [32] (95.32%). Pak choi productivity in both treatments was higher than that reported in other aquaponics studies [33][34][35] and was within the range of 0.5 to 7 kg/m 2 for soil culture [28]. This may be because the response of different plant varieties to environmental temperature can vary [25].…”

“…This may be because the response of different plant varieties to environmental temperature can vary [25]. There are also reports of pak choi grown successfully in aquaponics systems between 21.6 and 30.4 • C [33], and in hydroponic systems under greenhouse conditions between 34 and 45 • C [36,37] of environmental temperature. This suggests that the environmental temperature during the experiment was appropriate for pak choi development.…”

This study compares the aquaponics Nile tilapia (Oreochromis niloticus)-pak choi (Brassica chinensis) system with and without a bacterial biofilter (BF and NBF) in a tropical location. The aim was to determine whether a semi-intensive aquaponics system NBF could offer a production alternative for small-scale farmers in this region, both technically and biologically. The Tilapia aquaponics culture was continuously recirculated and water was added (influent) and removed (effluent) from the plant aquaponics culture every 24 h. Total ammonia nitrogen (TAN) and nitrite nitrogen (NO 2 − -N) were analysed in the plant aquaponics culture influent and effluent. At the end of the experiment the individual fresh total weight, dry total weight, edible weight, height and diameter of the pak choi plants were measured. None of the pak choi variables showed significant differences between treatments. TAN and NO 2 − -N were higher in the NBF influent than in the BF influent. TAN and NO 2 − -N in the effluent of both treatments were similar and lower than in the influent. The plant aquaponics culture therefore works as a biofilter and the NBF aquaponics system could be used for small-scale farmers in the tropics, with easier management and less costs than a BF aquaponics system.

“…For appropriate functioning, aquaponic systems require balancing multiple factors, including solution pH (Wongkiew et al, 2017a;Zou et al, 2016), plant and animal density (Buzby and Lin, 2014;Hussain et al, 2014Hussain et al, , 2015, solution flow rates (Hussain et al, 2015;Khater and Ali, 2015;Wongkiew et al, 2017b), economics (Quagrainie et al, 2018;Tokunaga et al, 2015), system configuration (Klemencic and Bulc, 2015;Monsees et al, 2017), and food safety considerations (Elumalai et al, 2017;Pantanella et al, 2015). Several authors have reviewed system types, management, and potential profitability of aquaponic production systems (Blidariu and Grozea, 2011;Lewis et al, 1978;Love et al, 2015).…”

The recent increased market demand for locally grown produce is generating interest in the application of techniques developed for controlled environment agriculture (CEA) to urban agriculture (UA). Controlled environments have great potential to revolutionize urban food systems, as they offer unique opportunities for year-round production, optimizing resource-use efficiency, and for helping to overcome significant challenges associated with the high costs of production in urban settings. For urban growers to benefit from CEA, results from studies evaluating the application of controlled environments for commercial food production should be considered. This review includes a discussion of current and potential applications of CEA for UA, references discussing appropriate methods for selecting and controlling the physical plant production environment, resource management strategies, considerations to improve economic viability, opportunities to address food safety concerns, and the potential social benefits from applying CEA techniques to UA. Author’s viewpoints about the future of CEA for urban food production are presented at the end of this review.
