Introduction to School Aquaponics
Defining Aquaponics
Aquaponics is an innovative and sustainable method of agriculture that combines aquaculture (the raising of fish and other aquatic organisms) with hydroponics (the cultivation of plants in water without soil). This symbiotic relationship creates a closed-loop ecosystem where fish waste provides an organic nutrient source for the growing plants, and the plants, in turn, purify the water, which is then recirculated back to the fish tanks. This process not only conserves water but also eliminates the need for chemical fertilizers, making it an eco-friendly alternative to traditional farming methods.
