Introduction to Aquaponics Aquaponics is a sustainable and innovative farming technique that combines aquaculture (fish farming) with hydroponics (soilless plant cultivation). This integrated system creates a mutually beneficial relationship between fish and plants. In aquaponics, fish are not just for the dinner table; they play a vital role in nourishing the plants, and the plants, in turn, help filter and purify the water for the fish. It’s a closed-loop ecosystem where waste from the fish becomes a valuable nutrient source for the plants, and the plants help maintain water quality for the fish.
