Aquaponic plant (water spinach, Ipomoea aquatica) was grown in floating trays in the selected ponds. The water quality parameters including, temperature, pH, dissolved oxygen, nitrite and ammonia were measured during study period.The level of ammonia was higher in catfish pond compared to carps pond water. Inversely, the dissolved oxygen content of catfish pond water was lower than that of carps pond. In the stinging catfish pond, the mean value (± SE) of plant length, weight, number of branches and leaves were recorded at 27.
