“…Aquaponics is the bio‐integration of recirculating aquaculture with hydroponics in one production system (Endut et al, 2010; Shete et al, 2013; Hussain et al, 2015; Nuwansi et al, 2016; Thomas et al, 2019). In aquaponics waste generating from the fish culture tank in the form of uneaten feed, faecal matter and dissolved organic matter is utilized as a nutrient for crop production, transforming the waste into a valuable resource.…”

This study was carried out to find suitable salinity for the best growth performance and survival of Nile tilapia (Oreochromis niloticus) with spinach (Spinacia oleracea) in an aquaponic system. The experimental design consisted of inland saline groundwater with salinities 3, 6 and 9 g L−1 as treatments and freshwater as control, carried out in 12 identical aquaponics units with fish stocked at a biomass 1.3 kg m−3 and plants at a density 40 m−2. Nile tilapia reared at salinities 9, 6 and 3 g L−1 showed significantly higher (p < 0.05) feed efficiency ratio and protein efficiency ratio compared to freshwater. The feed conversion ratio of fish at salinities 9, 6 and 3 g L−1 ranged between 1.31–1.43 and significantly differed from control. Final mean biomass were statistically similar at 9 g L−1 (5 kg m−3), 6 g L−1 (4.92 kg m−3) and 3 g L−1 (4.68 kg m−3). Survival of O. niloticus was 100% in all the salinities tested. Spinach was harvested twice during the study, in the first harvest the yield was observed higher in freshwater followed by 3, 6 and 9 g L−1, but in the second harvest, the higher yield was observed in 9 g L−1 followed by 6 g L−1, 3 g L−1 and freshwater. Based on the overall production performance and water quality parameters, a salinity of 9 g L−1 was found to be the best for the integration of Nile tilapia and Spinach in an aquaponic system.

“…The observed pH was found to be within the limit of 6-9 in the aquaponic system (Zou et al, 2016). The optimum growth performance of the fish, plant and nitrifying bacteria in an aquaponic system depends on the water temperature (Thomas et al, 2019). The temperature variation was found to vary under the influence of seasonal changes, varying between 24.5 to 26.63 C and was found to be F I G U R E 4 (a) Plasma glucose of Pangasianodon hypophthalmus exposed to different levels of potassium supplementation in aquaponic system; (b) plasma cortisol of P. hypophthalmus exposed to different levels of potassium supplementation in aquaponic system; (c) superoxide dismutase assay (SOD) of P. hypophthalmus exposed to different levels of potassium supplementation in aquaponic system; (d) catalase activity (CAT) of P. hypophthalmus exposed to different levels of potassium supplementation in aquaponic system (C = 0 mg l À1 K + , T1 = 90 mg l À1 K + , T2 = 120 mg l À1 K + , T3 = 150 mg l À1 K + and T4 = 180 mg l À1 K + )…”

This study evaluated the effect of different potassium supplementation dosages on the physiological responses of Pangasianodon hypophthalmus reared in an aquaponic system with Spinacia oleracea L. for 60 days. The system comprised of a rectangular fish tank of 168 l capacity (water volume = 100 l) with nutrient film technique (NFT)–based hydroponic component with fish to plant ratio of 2.8 kg m−3: 28 plants m−2 in all the treatments. The osmoregulatory and stress parameters of P. hypophthalmus at four different potassium dosages of T1 (90 mg l−1), T2 (120 mg l−1), T3 (150 mg l−1) and T4 (180 mg l−1) were compared with C (control, 0 mg l−1) to examine the potassium level to be applied to aquaponics. The water quality parameters and fish production were found to have no adverse impact due to potassium supplementation. The spinach yield during two harvests, i.e., before and after potassium supplementation, revealed that the yield was significantly higher (P < 0.05) after supplementation with the highest yield in T3 and T4. The osmoregulatory parameters such as plasma osmolality, Na+, K+ ATPase activity in gill and plasma ionic profile (Cl−, Ca2+ and Na+) showed an insignificant variation (P > 0.05) between control and treatments except for higher plasma potassium concentration (1.98 ± 0.19 mmol l−1) in T4. The stress and antioxidant enzyme analysis exhibited significantly higher plasma glucose and superoxide dismutase (SOD) activity in gill and liver in T4, whereas cortisol and catalase showed an insignificant difference (P > 0.05). The experimental findings demonstrated that the potassium dosage up to 150 mg l−1 could be suggested as optimum for P. hypophthalmus and spinach aquaponics without impairing the health and oxidative status of P. hypophthalmus.

“…Therefore, aquaponics could be one of the solutions to save both water and land. Aquaponics can be referred as combination of recirculating aquaculture with hydroponics in a symbiotic production system (Rakocy et al, 2006;Endut et al, 2010;Thomas et al, 2019). Aquaponics involves natural processes like biological oxidation of ammonia (nitrification) and phytoremediation (Fronte et al, 2016;Nuwansi et al, 2019).…”

A 60-day experiment was conducted to optimize fish and plant component ratio in a recirculating aquaponic system. Three different fish: plant component ratio of Rohu (Labeo rohita) spawn to Spinach (Spinacia oleracea) plant viz. T1 (40 spawn:10 plants), T2 (40 spawn:14 plants) and T3 (40 spawn:18 plants) were assigned as treatments. All the treatments were compared for fish growth, plant growth, and various water quality parameters were observed to determine the best component ratio which maintains better water quality and gives better growth. Among all the treatments, the higher growth rate of fish was observed in T2 (5.08±0.12) followed by treatment T3>T2>C. At the end, the total production of spinach in terms of weight was 508.10±8.89 g in T2 followed by treatments T3 and T1. Based on the results, the fish: plants component ratio of 40 spawn:14 plants can be recommended for production of rohu seed and spinach in recirculating aquaponic system
