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
