Aquaponics is a sustainable agricultural system that combines aquaculture (the farming of fish) and hydroponics (the growing of plants without soil) in a symbiotic environment. In aquaponics, fish waste provides essential nutrients for plants, and the plants in turn filter and clean the water for the fish. This closed-loop system allows for the efficient production of both fish and vegetables in a single integrated system. Aquaponics is known for its water efficiency, as it uses significantly less water than traditional farming methods, and is also environmentally friendly as it eliminates the need for chemical fertilizers and pesticides. Overall, aquaponics is a promising approach to sustainable food production as it maximizes resource utilization and minimizes environmental impact.
