Aquaponics & Organic Farming


Aquaponics refers to any system that combines conventional aquaculture (raising aquatic animals such as snails, fish, crayfish or prawns in tanks) with hydroponics (cultivating plants in water) in a symbiotic environment. In a normal aquaculture, excretions from the animals can accumulate in the water and increase toxicity. In an aquaponic system, water from an aquaculture system is fed to a hydroponic system where the by-products are broken down by nitrifying bacteria initially into nitrites and subsequently into nitrates which are utilized by the plants as nutrients. The water is then re-circulated back to the aquaculture system.

Aquaponics addresses three key concerns for food security for India in coming years. They are:

  • High quality organic produce.
  • Almost 90% saving of water for crops (compared to same amount of crops grown in conventional agriculture)
  • Almost 6 times higher yield per unit of land. At present there are four full-time apprentices who are being trained in the methodologies of this new farming technique. Each of them comes from a different background with various degrees of the knowledge on conventional agriculture
