Aquaponics-A New Approach for Vegetable Production

Aquaponics combines a re-circulatory aquaculture system with a hydroponics system in an integrated symbiotic farming concept that ensures efficient nutrient recycling. In this system, the excretory products of the fish are broken down by microorganisms and the resultant by-products are inputted into the hydroponic system for plant growth. As the plant utilizes these metabolites, it purifies the water reused in the aquaculture system for fish production. Hence, this allows the sustainable growth of the crop without the use of chemical fertilizer and the fish with a lowered water budget. The concept of the aquaponics system takes root from the ancient practice of integrated fish farming, such as the rice-cum fish and the poultry-cum fish culture.
