Abstract
Water is one of the important component in aquaponics system and it plays a vital role in ensuring effectiveness of working of the system. The present study was conducted to evaluate the quality of water used in the floating raft aquaponics system for 49 days. The experiment was carried out with the control and two treatments (T1= Tilapia, and T2= Rohu) with spinach (Spinacia oleracea) plant. Water temperature, pH, dissolved oxygen, nitrate, nitrite, phosphate and total hardness are among the important water quality parameters. The result showed variations in water quality parameters that existed in both tanks but these were favourable for the survival and growth of the fish. The average water quality parameters including water temperature (25°C, 27°C), pH (7.2, 7.3), dissolved oxygen (5.4 mg/l, 5.3 mg/l), nitrate (0.07 mg/l, 0.09 mg/l), nitrite (0.08 mg/l, 0.10 mg/l), phosphate (0.15 mg/l, 0.07 mg/l) and total hardness (266 mg/l, 240 mg/l) in T and T were observed respectively. Therefore, it could be concluded that the whole system was working properly and there was a perfect1 2 symbiosis between fish, microorganisms and plants.
