Aquaponics, our way of looking at it

Aquaponics organic farming movement is the combination of aquaculture (farming fish) and hydroponics (growing plants without soil).  It is the practice of using nitrogen rich water that fish are reared in to grow vegetables.

Feed fish.
Fish metabolites remediated by bacteria.
Fish water nourishes plants.
And is recycled.

Two crops from one input.
No effluent (negligible environmental impact).
Productivity six times higher than soil agriculture.
Soil-borne pests, diseases, and weeds are eliminated.
No need for massive pesticide use
No need for chemical fertilizers
Ability to exert greater control over plants ensuring uniform results
Much less water is required than for conventional crop production in the soil
Lower labour requirements
Large plant populations could be grown in very small limited areas.
Accelerated growth
Food crops mature more rapidly and produce greater yields
Quality of most vegetables is better than those of soil-grown vegetables are.
Produce grown aquaponically is found to have a much longer shelf life as well as better keeping qualities.
Areas with little rainfall, poor, or no soil and difficult access were found ideal for aquaponics culture.
New employment opportunities.

About VKN
Vijayakumar Narayanan (vkn) is the founder and director of NARDC (,, an aquaponics farmer based in Nanniode, India, that provides aquaponics on-farm research, information, aquaponics education/national workshops, commercial aquaponics consulting and aquaponics supplies in India.  Much of the NARDCs profits go to help spread aquaponics in India.

VKN is a geek farmer with 20+ years of executive managerial experience working in a variety of roles and as a soldier/educator in Indian Army Educational Corps, he envisions the impact of aquaponics technologies on the future of agriculture, and helps farmers, farming entrepreneurs, government agencies and companies make it a reality.  He also do key-note speaking assignments on the subject of aquaponics.

About NARDC :
We support the development, adoption and implementation of aquaponics organic farming movement in India to benefit the people, environment and economy.  Nanniode Aquaponics Research and Development Center is a self-funded on-farm aquaponics research and development center in India presently focusing and perfecting on mainly three aquaopnics model applications in India.  

1. One cent aquaponics; build area 40 m2 (suitable for self-providing domestic growers, food production for self, family, relatives and friends)
2. Village-scale aquaponics; build area 200-500 m2 (owner-operated basic commercial model, food production for the local community)
3. Commercial aquaponics; build area >= 1000 m2 (for large-scale commercial growers/enterprises)

Join the NARDC campaigns:
1. Grow More Food Locally and Sustainably.
2. Empower a Growing Generation.
3. Create a Successful Aquaponics Farming Community in India.

Creation of a knowledge base of aquaponics in India is part of NARDC's mandate.  Our mission is to teach and educate people in advance technologies on aquaponics for employment generation and sustainable livelihood. Training facilities at the NARDC center are of class, faculty is highly educated and experienced in aquaponics farming for over 5 years.  NARDC organises national level aquaponics design and technology training workshops in India.  For small and marginal farmers it is a regular one day activity. For others, it is being organised one-on-one on commercial lines and on consultation request.  A professional consulting fee is charged for the same.

NARDC has full circle aquaponics technology adaptation and demonstration sites at Nanniode, Palakkad, Kerala, India.  They are working models of sustainable production of plants and fish. NARDC was formally established in June 2013 after several months of trials and experiments since 2012.  As an aquaponics knowledge hub presently in India, NARDC has been functioning as a centre or a local focal point for the exchange of aquaponics knowledge, support, research, development and sharing ideas.  We are on a mission creating easy and cheap way of aquaponics systems affordable to poor and marginal farmers in India.  There are many different aquaponics techniques and designs involving a variety of construction materials and equipment available in the aquaponics world, however NARDC looks at only the ones we have created and tested ourselves at our demo and commercial sites.  We are researching and trying out new things to perfection based on our own on-farm experiments and findings.
