Aquaponics (AP) is the combination of aquaculture (fish farming) and hydroponics (soil-less plant culture).
AP is the cultivation of fish and vegetables/plants together in a constructed, re-circulating ecosystem utilizing natural bacterial cycles to convert fish wastes to plant nutrients, as shown in the schematic.

.
In aquaponic systems, the nutrient-rich water that results from raising fish provides a source of natural fertilizer for the growing plants. As the plants consume the nutrients, they help to purify the water that the fish live in. This creates a sustainable ecosystem where both plants and fish can thrive,
• Using less water and space, • Producing no waste water and pollutants compared to
conventional methods, while • Using semi-skilled and local labor for production, • Resulting in creation of sustainable livelihoods.

ADVANTAGES
1. Water Reuse:
• Aquaponic systems are completely contained systems that reuse most of the water from the fish holding tanks.
• Wastes are removed, water is treated and recycled back to the tanks.
• Water loss during waste removal/evaporation is typically 1-1.5% of the total volume of water.
The main advantages of Aquaponics over competing technologies for fish and vegetable growth are:

2. Space and Production Efficiency:
a) The productivity is higher than conventional aquaculture, while allowing for optimal year-round growth.
b) Market-sized fish can be produced in 9 months compared to 15-18 months in conventional fish farms.*
c) For example, it takes 197.6 acres of open ponds to produce the same amount of shrimp that an aquaponic farm can raise on just 6.1 acres of land!*

3. Biosecurity:Aquaponic fish farms are fully closed & controlled. They operate without any inputs of chemicals, drugs or antibiotics, and are therefore biosecure—as diseases and parasites cannot get into the system. This ensures a more natural product for consumers. AP systems can be:
a) Located within urban communities that will use the fish, rather than by natural water sources like oceans or rivers, thus having a smaller carbon footprint due to reduced transportation requirements; and
b) Need not be located on water supply systems or for drainage requirements.

4. Aquaponic is Organic :As long as it is ensured that the fish food is organic, the fish and vegetables produced using aquaponic technologies can therefore be classified as organic products.
5. Aquaponic farms are ecologically sustainable:Aquaponic farm can produce, for example, the same amount of lettuce as traditional agriculture using half the amount of water, plus producing fish.
6. Aquaponic farms are more efficient than other forms of fish farming:Provide better quality products with higher growth rates, diverserevenue streams, scalability, array of products and flexibility of location.

ADVANTAGES
ADVANTAGES OF AQUAPONIC SYSTEMSThe problems with traditional: The advantages of Soil-based Gardening Hydroponics Intensive Aquaculture Aquaponic systems
• Weeds;
• Relatively large amounts of water required, at regular intervals;
• Knowledge required to know when to water, when and how to fertilize, and what is the composition of the soil;
• Heavy digging, the bending, the back strain;
• Presence of soil-borne insects;
• Pests.
• Relies on the careful application of expensive, man-made nutrients made from mixing together a concoction of chemicals, salts and trace elements;
• The strength of this mixture needs to be carefully and constantly monitored, along with pH values, using expensive meters;
• Water in hydroponic systems needs to be discharged periodically, as the salts and chemicals build up in the water which becomes toxic to the plants. This is both inconvenient and problematic;
• Prone to a disease called “pythium” or root rot.
• The tank water becomes polluted with fish effluent which gives off high concentrations of ammonia.
• Because of this unhealthy environment fish are prone to disease and are often treated with medicines, including antibiotics.
• Water has to be discharged at a rate of 10-20% of the total volume in the tank daily. This uses a tremendous amount of water.
• This polluted water is often pumped into open streams where it pollutes and destroys waterways.
• Give fish inexpensive fish feed, food scraps, and food that you grow yourself.
• We need to carefully monitor the aquaponic system during the first month, but once the system is established, we only need to check pH and ammonia levels occasionally, or if plants or fish seem stressed.
• We NEVER replace the water; we only need to top it off as it evaporates.
• “Pythium” is virtually non-existent in aquaponic systems.
• Fish disease is rare in an aquaponic system.

1. Raft system:
In a raft system (also known as float, deep channel and deep flow) the plants are grown on Styrofoam boards (rafts) that float on top of water.
Water flows continuously from the fish tank, through filtration components, through the raft tank where the plants are grown andthen back to the fish tank.

2. Media-filled bed
A tank or container is filled with gravel, perlite or other media for the plant bed. This bed is periodically flooded with water from the fish tank. The water then drains back to the fish tank.
This method uses the fewest components and no additional filtration, making it simple to operate. The production is, however, much lower than the two other methods described here. The media-filled bed is often used for hobby applications where maximizingproduction is not a goal.

SEAWEEDS
CASE STUDIES
"Most people do not realize that seaweed and shellfish, not fin fish, are by far the biggest elements of the world's marine aquaculture industry“ -- says Dr. Amir Neori, a senior scientist at the National Centre for Mariculture at Eilat, Israel
• Edible seaweed can be grown for sale in six weeks, instead of six months for fin fish and crustaceans, and upto six years for abalone.
• Cash crops of seaweed can be grown in conjunction with fin fish farming, with the uptake of organic wastes that would otherwise pollute water, as seaweed's role -- nature's nutrient capture system.
• Every ton of fin fish waste could produce upto seven tons of plant materials such as lettuce in fresh water Aquaponics and edible seaweed in salt water Aquaponics.
• Seaweeds produce the most valuable omega-3 oil, vital for human health.
• Aquaponic farms in future will be based on seaweed production, as it makes economic, environmental and human health sense.

• 5,000 kg of fish per year; at Rs.100/kg, this translates to Rs.5 Lakhs per year;
• 37,800 heads of lettuce with the estimated weight of 0.65 pounds per head, which equals to 24,570 pounds (or 11,168 kg) of lettuce per year; at Rs.40/kg, this translates to Rs. 4.5 Lakhs per year. ….This implies that:
• The direct economic value of aquaponic products comprising 5,000 kg of tilapia and 11,168 kg of lettuce totals to about Rs.9.5 Lakhs per year.
• [Facility Cost:Annual Sales Revenue] ratio is [Rs.14 Lakhs/Rs.9.5 Lakhs] = 1.5.
• Large commercial operations require one full-time, semi-skilled employee per 1,000 m2 of enclosed space; for each 4,000 m2 of enclosed space, an extra full-time person is required to help with the fish and plant harvesting. There are NO special skills required to operate any facet of the aquaponic systems.
• The payback/break-even point from commercial aquaponic projects should be less than two years.

CASE STUDIES
• Effluents were collected in a sump from which a 1-horsepower in-line pump recirculated the water back to the fish culture tanks at a rate of about 250 L/min.
• The hydroponic component performed as biofilter and effectively managed the water quality.
• Fish production was staggered to harvest one of the four fish tanks at regular intervals when fish attained a minimum weight of 250 grams.
• Out of the total eight harvests in 13 months, net fish production per harvest averaged 33.5 kg/m3 of water with an overall water consumption of 320 L/kg of fish produced along with the production of leaf lettuce at 42 heads/m2 of hydroponic surface area (estimated weight of 0.3 kg per head ≡ 12.4 kg/m2).
• Only 1.4% of the total system water was added daily to compensate the evaporation and transpiration losses.
• A ratio of 56 gm fish feed/m2 of hydroponic surface effectively controlled nutrient buildup in the effluents. However, plant density could be decreased from 42 to 25–30 plants/m2 to produce a better quality lettuce.

Message from Nate StoreyPARTNERS
NETWORKS
I am writing this letter to express strong support for Dr. SubhrankarMukherjee as he advocates the use of aquaponics in urban environments for food security, energy efficiency and economic development. Dr. Mukherjee has demonstrated a great deal of expertise and enthusiasm in moving this technology forward and has a great deal to offer this growing movement.
Aquaponic production has a great deal of potential for high density food production for diet supplementation, and simplifies many of the problems experienced in traditional hydroponic vegetable production. Almost any crop can be cultured in aquaponic systems and once established, systems can be very productive and simple to operate. For this reason aloneaquaponic production has a great deal of potential to improve the lives of many Indians- especially in urban environments.
… In addition to these potential benefits, the potential production density of aquaponic systems make them ideal for confined spaces and operations where space is valuable or limited.Small aquaponic systems operating on rooftops or exposed walls of buildings have potential to supplement the diets of theoperators and potentially produce enough excess vegetables to sell at market, supplementing budgets as well as diets.
The productivity of aquaponic systems can be further increased by using vertical production technology. By using single face production towers, productivity can typically be doubled to quadrupled, resulting in more efficient production and allowing the cultivation of unused urban surfaces, like walls and the sides of buildings.
… I am excited to hear about Dr. Mukherjee’sopportunity to speak at the Congress on Urban Green Spaces. I think that he will have a great deal of valuable information, insights and visions of a green, clean future for urban agricultural enterprise.

To that extent, Dr. Subhrankar Mukherjee has my full support in helping spread the introduction of Aquaponics in Bharat, my Motherland. I am sending him a brief extract of my Aquaponics workshop training slides so as to give the audience a glimpse into the possibilities of incorporating Aquaponics in the fight against world hunger.For more details, please visit [www.Sahibaquaponics.com]
Support Statement for Aquaponics work being highlighted by Dr. Subhrankar Mukherjee
My birth name is Pardeep Kumar Vedi and I am an NRI living in USA …In the world of Aquaponics, I go by the name Sahib Punjabi.
These are the types of systems that Tim Mann was referring to when he wrote… “Sahib is dedicated to “feeding the villages” of the world, these are his words for teaching the poorest people in the world how to feed themselves using Aquaponics. He is developing Aquaponics systems in Winter Park, Florida, that are the prototypes for affordable systems that will be appropriate for economically disadvantaged and developing nations.”

URBAN
AGRI
Urban agriculture relates to:
• Agricultural production (crops and livestock) in urban and peri-urban areas for food and other uses,
• The related transport, processing and marketing of the agricultural produce, and
• Non-agricultural services provided by the urban farmers (water storage, agrotourism, urban greening and landscape management, and others)

IMPACT
URBAN AGRI
Urban agriculture has a positive impact on the:• Greening of the city • Improvement of the urban micro-climate (wind breaks, dust
reduction, shade, sequestration of CO2 and other pollutants), and • Conservation of soil, water, biodiversity and the cultural landscape.
Cities in areas with higher rainfall often use the agricultural areas in and around the city as buffer and water storage facility.
By producing fresh foods close to the urban consumers, urban agriculture contributes to the reduction of the:
• Ecological foot print of the city; and • Energy consumption in transport, cooling and packaging of food
produced in areas further away.THERE IS A GREAT NEED FOR PROTOTYPES & POLICIES

SPIRULINA
.
SPIRULINA AS FISH FEED.
Spirulina a blue-green algae, is known for its positive probiotichealth effects in animals, humans and fish alike. It is commonlyfed to fresh and salt water fish and results in healthier fish with a higher resistance to infection and illness.
Experts recommend a mixed diet of spirulina and fish flakes or brine shrimp.
At ARTS, we have undertaken research and development of Spirulina in both, village and urban environments.
For more information, please visit our spirulina website at: [http://www.sankalpacmfs.org/src/01liv/01liv.html#8] or download [http://www.sankalpacmfs.org/src/wp/Spirulina_1page.flyer.pdf].

Strategic Plan for Pedagogy:• Educate students about global environmental issues while engaging and
empowering them to create localized solutions.
• Expose students to ‘critical pedagogy’ & ‘real-world teaching experiences’.
Critical Pedagogical Values:• Reciprocation of teaching and learning: Having the courage to teach
ourselves and the modesty to learn from ourselves.
• Problem-based learning: Explore real world solutions through an interdisciplinary and collaborative lens.
• Place-based education: Use of local environment and community to connect students to the real world, in which solutions are applied through collaborative effort.
• Transformative education: Knowledge is generated by students to improve themselves and their society; Learning is grounded in action that benefits the community beyond the classroom.

HOW
TO
BUILD
#1 and #2: Hooking the intake tube into the bottom of the growing trough. NOTE! You do NOT have to use a plant growing trough like this one. Any tub would do.
#3 and #4: Hooking the water line into the pump (make sure you’ve got your water flow going the right way!)
#5:Hooking in the short piece of PVC pipe that will drop the water back down into the cooler/fish tank.

CONCLUSION
.
Aquaponic systems are not only eco-friendly,
sustainable, provide food security and create
sustainable livelihoods, but they are also
commercially feasible and make good
business sense—especially in a world of
dwindling and escalating costs of natural
resources, such as land and water.
