What is Aquaponics?
● Aquaponics is a form of agriculture that combines raising fish in tanks (aquaculture) with soilless plant culture (hydroponics).
● Aquaponics is an emerging technique in which both fish as well as plants complement each other to sustain and grow.
● The fish waste provides fertiliser for growing plants. The plants absorb nutrients and filter the water, which is used to replenish the fish tank.
● Benefits of Aquaponics:
○ Extremely water efficient.
○ Does not require soil.
○ Does not use fertilisers or chemical pesticides.
○ Reduces pressure on land and cuts down operational costs among others.
○ It does not require farmland with fertile soil.
○ It provides Food Security and a better source of income for farmers
● Disadvantages: Set up cost in aquaponics is high. Normally an average investment of at least Rs 2.5-3 crore per acre
