- 1. Aquaponics is a sustainable farming method that combines aquaculture (raising aquatic animals) and hydroponics (growing plants in water) in a symbiotic environment. In aquaponics, fish waste provides nutrients for the plants, and the plants filter the water, creating a closed-loop system that is efficient and environmentally friendly. This system mimics natural ecosystems and can be used to grow a variety of plants and fish, making it a versatile and innovative approach to food production. Aquaponics requires less water and space compared to traditional farming methods, and it can be done on a small scale in home gardens or on a larger commercial scale. By utilizing natural processes and reducing the need for synthetic fertilizers and pesticides, aquaponics offers a more sustainable and organic way to produce fresh food.
