Aquaponics is a sustainable system that integrates aquaculture and hydroponics. It allows fish and plants to be farmed together in a symbiotic environment where the fish waste fertilizes the plants and the plants help filter the water for the fish. Historically, aquaponics systems were developed by ancient civilizations like the Incas, Aztecs, and Cambodians. Modern aquaponics provides advantages like reduced labor, higher production rates, income from two products, and reuse of aquacultural waste. While the initial costs can be high, aquaponics is a more sustainable and efficient way to farm.
