Aquaponics is a sustainable food production system that combines aquaculture and hydroponics, using nutrient-rich water from fish tanks to fertilize plants in a closed-loop system. Popular choices for aquaponic systems include lettuce, kale, spinach, tomatoes, watercress, radishes, carrots, strawberries, basil, mint, cucumber, cauliflower, cabbage, sunflowers, and peppers. Each plant has specific requirements for nutrients, temperature, pH levels, and growing medium, with some plants like watercress and carrots needing special attention. It is important to choose the right fish species, such as tilapia and koi, to match the plants' needs. Aquaponics is not only efficient but also allows for the growth of a variety of fruits, vegetables, flowers, and ornamental plants without the use of chemical fertilizers or pesticides, making it a promising climate solution for sustainable agriculture.
