In 21st century one of the environmentally sustainable farming method, an integrated agri-aquaculture system and a viable food growing technology which connects consecutive aquaculture with hydroponics in a symbiotic condition will be adopted by farmers to meet the demand of the growing population. The present research was accomplished to evaluate the relative performance of gravel media (M1), coconut husk media (M2) and a composite media of gravels and coconut husk (1:1V) (M3) as media in aquaponic system to grow green gram (Vigna radiata) and Nile tilapia (Oreochromis niloticus). Each treatment had three replications of similar bedding media. The resultant effects of these treatments revealed better performance of Vigna radiata in the treatment T1 performed best followed by T2 and T3, respectively in terms of media plant growth performances was noted to be in the following order M3> M2>M1 with respect to duration of plant growth in different growth periods, plant height, number of leaves per plant, leaf area and number of branch per plant. Gravel substrate grown Vigna radiate showed least performance in growth propagation. The selected media and treatment methods, the water and nutrient quality supports for fish and plant growth. At the end of experiment the length and weight gain of experiment fish was 84.95±0.84 cm; 142.5±0.03gm. In the present study the survival rate of fishes were 95% and above in all the selected treatments. So, the present experimental study proves aquaponic as an alternative uses of agricultural by-products due to superior growth observed in this study, it is also highly recommendable due recycling and conversion of waste to product.
