Water quality management in aquaponics system

December 2022

The aquaponics system is the culture of fish and vegetable plants in the combined circulatory aquatic environment in that water quality plays an important role in the yield of the system and in the present study important water quality was evaluated to enhance the efficiency of an aquaponics system. This research was conducted in two different treatments which contain rohu and tilapia with tomato ... [Show full abstract] plants in 10 replications and simultaneously important water quality parameters including air temperature (C), water temperature (C), pH, dissolved oxygen (mg/l), electrical conductivity (mS/cm-1), total hardness (mg/l), total alkalinity (mg/l), ammonia (mg/l), nitrate (mg/l) and nitrite (mg/l) were analysed. The findings of the present study show the range of air temperature from 25.30 to 29.80 degree C, water temperature from 25.45 – 27.86 °C and 25.85 - 27.83 °C, pH 7.39 – 7.63 and 7.40 – 7.64, dissolved oxygen 5.46 – 6.0 mg/l and 5.45 – 6.0 mg/l), electrical conductivity 222.38 – 229.63 mS/cm-1 and 220.75 – 228.75 mS/cm-1, total hardness 578.25 – 635.75 mg/l and 581.25 - 633 mg/l), total alkalinity 110.5 – 118 mg/l and 107.25 – 119.75 mg/l, ammonia 0.001 – 0.003 mg/l and 0.001 – 0.002 mg/l, nitrate 0.05 – 0.07 mg/l and 0.05 – 0.07 mg/l and nitrite 0.03 – 0.05 mg/l and 0.04 – 0.06 mg/l) in T1 and T2 respectively. These water quality parameters were compared with optimum values referred to by different authors and found suitable for cultivation in the system.

Growth of tomato (Solanum lycopersicum) plant in floating raft aquaponics system

May 2022

The present paper is elucidated the growth of tomato (Solanum lycopersicum) plant in the floating raft aquaponics system. In this experiment the tomato seedlings were transplanted in aquaponics unit with the help of thermocoal cup and floating sheet which were grownup for 60 days. On the basis of stocked fish species fingerlings in 400 L capacity clean and disinfected circular tanks the ... [Show full abstract] experiment was categorized in two treatments (T1 tomato plant with rohu fish and T2 tomato plant with tilapia fish) in 10 replications. During the present study, the important plant growth parameters including net length gain, shoot length and root length were measured while total number of leaves was counted. The findings of present study on growth parameters like net length gain (11.880 and 8.886 cm), shoot length (10.521 and 6.053 cm), root length (5.900 and 4.269 cm) and increment in leaves number (12 and 10) were noted in T1 and T2 respectively. On the basis of these findings it can be concluded that tomato plant was healthy and plant growth was satisfactory in both treatments. This also concluded that aquaponics system could be the alternative of food and sustainable vegetable production system.

July 2023 · JOURNAL OF EXPERIMENTAL ZOOLOGY INDIA

The present research work was done to elucidate tomato vegetable plant growth cultivated in a floating raft aquaponics system with rohu and tilapia fishes. The experiment was conducted for 60 days in two treatments i.e., plant+rohu fish(T1) and plant+tilapia fish (T2). The replications (10) containing 400 L water stocked with fish fingerlings in the ratio of 1:1(plants and fish) were reared to ... [Show full abstract] follow the standard cultivation methods,e.g., aeration, supplementary feeding, water exchange,etc. and growth measurements were taken every 15 days. The findings show that initial and final growth of 13.763 cm and 25.643 cm of plants were noted in T1, whereas 13.581 cm and 22.467 cm were recorded in T2. The net gain in plant growth was 11.880 cm inT1 and 8.886 cm inT2. Similarly, these findings indicated the increasing order 2.314<2.621<3.010<3.935 and 1.462<1.966<2.547<2.911 of plant growth at fortnightly intervals in T1 and T2, respectively. On the basis of these findings, it can be concluded that the growth of the tomato plant was more in T1 compared to T2 and plant growth in T1 and T2 variation was significant (p<0.05) may be due to more nitrogenous compounds released by the fish waste.

December 2021

The present study was conducted to determine the growth performance of rohu and tilapia fingerlings in aquaponics with tomato plants. In this experiment, the fingerlings of selected fishes were reared for 60 days and supplementary feed (groundnut oil cake, rice bran, wheat flour and vitamin-mineral mixture in ratio of 40:40:19:1) was given to them. The experiment was carried out in two treatments ... [Show full abstract] (T1 for rohu and T2 for tilapia) with 10 replications and 400 L capacity clean and disinfected circular tanks. The growth parameters including length gain in T1was 1.074 cm) and in T2 was 0.935 cm, whereas weight gainin T1 and T2 was 8.130 and 4.403 gm, respectively. The specific growth rate (SGR) in T1 (1.272), in T2 (0.845) and feed conversion ratio (FCR) in T1 (3.536), in T2 (5.002) was observed. On the basis of these findings, it can be concluded that the growth of the studied fishes was satisfactory and growth differences in T1 and in T2 was significantly different at 5% level of significance. It is also concluded that aquaponics could be the alternative of the food production system.
