The present research was conducted to observe the growth performance of rohu and tilapia fingerlings with tomato (Solanum lycopersicum) plants in aquaponics. In this experiment, the fingerlings of selected fishes and tomato plants were reared for a period of 60 days and during this experiment, supplementary feed (groundnut oil cake, rice bran, wheat flour, and vitamin-mineral mixture in 40:40:19:1 ratio) was provided.
The experiment was carried out in two treatments (T1 - rohu and T2 – tilapia were reared with tomato plants) and 10 replications in 400 liters capacity tanks were used to maintain water aeration. The results show that small variations in water quality parameters existed in both treatments, but these were favorable for the fish survival and growth. The average water quality parameters including Air temperature (28.7 OC), Water temperature (27.12 OC, 26.83 OC), pH (7.5, 7.4), Dissolved oxygen (5.6 mg/l, 5.6 mg/l), Electrical conductivity (2.261 mS/cm-1, 2.256 ms/cm-1), Total hardness (611.71 mg/l, 608.92 mg/l), Total alkalinity (112.75 mg/l, 111.21 mg/l), Ammonia (0.002 mg/l, 0.001 mg/l), Nitrate (0.060 mg/l, 0.061 mg/l), and Nitrite (0.043 mg/l, 0.047 mg/l) in T1 and T2 were observed during experimental period.
Growth parameters including length gain in T1 (1.074 cm) and T2 (0.935 cm), weight gain in T1 (8.130 gm) and in T2 (4.403 gm), specific growth rate (SGR) in T1 (1.272) and in T2 (0.845) and feed conversion ratio (FCR) in T1 (3.536) and in T2 (5.002) were observed, which were found satisfactory. The growth of the plant was 11.880 cm. in T1 (rohu rearing tanks) and 8.886 cm. in T2 (tilapia rearing tanks). The gain was significant at the 5% level of significance. According to the findings of the current study, it can be concluded that in an aquaponics system, rohu fingerlings are superior for tomato plant growth performance in an aquaponics system with an aqua-friendly rearing environment.
