“…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).…”
