Here are some highlights of the advantages of this method of food production:
Aquaponics is an ecosystem in which freshwater fish, plants, bacteria, and small to micro aquatic organisms working in symbiosis.
Water is continuously recycled leading to significantly less water use than traditional agriculture and commercial aquaculture. Currently, 70% of freshwater available for human consumption is used in soil-based agriculture. (pc.gov, UNESCO)
The continuous recycling of water and fish waste eliminates waste unlike commercial aquaculture that must consistently pour out water full of accumulated nutrients and waste.
Aquaponics is an organic closed loop system in which the only input is fish food. Fertilizer is provided by the fish waste
Places with poor quality soil, limited arable land and drought can grow their own food using aquaponics.
