It is a ppt of aquaponic system in agriculture

1. INTRODUCTION
AQUAPONICS IS A COOPERATION BETWEEN PLANTS AND FISH
AND THE TERM ORIGINATES FROM THE TWO WORDS
AQUACULTURE (THE GROWING OF FISH IN A CLOSED
ENVIRONMENT) AND HYDROPONICS (THE GROWING OF
PLANTS USUALLY IN A SOIL-LESS ENVIRONMENT).
AQUAPONIC SYSTEMS COME IN VARIOUS SIZES FROM SMALL
INDOOR UNITS TO LARGE COMMERCIAL UNITS.

2. HISTORY
• Aquaponics can be traced back to the Aztec Indians in mexico who raised plants
on rafts on the surface of a lake around 1000 AD.
• South China and the whole of Southeast Asia, where rice was cultivated and
farmed in paddy fields in combination with fish, are cited as examples of early
aquaponics systems.
• Research into aquaponics commenced in the 1970’s and is continuing with many
universities across the world refining technologies to improve output. In particular,
Dr. James Rakocy of the University of the Virgin Islands has been working to refine
aquaponic systems over the past 25 years. Aquaponics has gained momentum
over the past few decades. In the early 2000’s large commercial aquaponics
operations were implemented and in-depth research into their productivity was
undertaken.

4. WORKING MODEL OF AQUAPONIC
SYSTEM
• In aquaponics, the plants are grown in the grow bed, and
fish are placed in the fish tank. The nutrient-rich water from
the fish tank that contains fish waste is fed to the grow bed,
where billions of naturally occurring beneficial bacteria
break the ammonia down into nitrites and then into
nitrates.Plants absorb these nitrates and other nutrients to
help them grow. The plant’s roots clean and filter the water
before it flows back into the fish tank for the fish to live. The
fresh, clean, and oxygenated water recirculates back to the
fish tank, where the cycle will begin again.

5. WORKING MODEL OF AQUAPONIC
SYSTEM IN DETAIL
• Explanation of the Nitrogen Cycle: In aquaponics, the nitrogen cycle is a
fundamental process that transforms toxic ammonia from fish waste into less
harmful nitrates. Fish excretes ammonia that accumulates in the water. Beneficial
bacteria, specifically Nitrosomonas, convert ammonia into nitrites. Another type
of beneficial bacteria, Nitrobacter, then converts nitrites into nitrates that serve as
a valuable nutrient source for plants.

6. • Nutrient Absorption by Plants: As water from the fish tanks flows into the grow
beds or PVC pipes plants absorb the nitrates through their root systems. These
nitrates provide essential nutrients like nitrogen and phosphorus that promotes
plant growth and development.
• Purified Water Returning to the Fish Tanks: The plants’ uptake of nutrients fuels
their growth and naturally filters the water. Purified water, now clean of excessive
nitrates and other waste, is then recirculated back into the fish tanks, creating a
closed-loop system.

8. OBJECTIVE OF AQUAPONICS
• To demonstrate the potential peroductivity,
efficiency and associated costs.
• To grow leafy green crops in this setup.
• To reduce environmental hazardious impact.
• To reduce the weeding process

9. BENEFITS OF AQUAPONICS
• This system capture a high proportion of nutrients.
• Reduced labour and improved working conditions.
• The use of water is 10% less than the conventional soil based agriculture systems.
• High levels of nutrient utilization occurs in the aquaponic system.
• This system can be established in rural or urban environment where land is very
limited or of very poor quality.

10. IMPORTANCE OF AQUAPONICS
• It is environmental friendly.
• Organic in nature
• Sustainable Way of agriculture
• Produces healthy crops.
• Increases yield by 30-40% than other methods. Requires no weeding.
• No use of pesticides for crop growth .
• No need of adding fertilizer to the crop.

11. ROHIT GUPTA (THE FOUNDER OF AARPUN
FARMS)
• He visited different research centres to learn more about aquaponics. Once
he gained enough confidence to start a farm, he quit his job in Mumbai, and
moved to his native town in Punjab, in 2018 . With help from his uncle and
cousin Saurabh Agrawal, Rohit opened Aarpun Farms in Lambra village in
Jalandhar district. The location of the farm, which spans over 2.25 acres, was
decided keeping in mind operational and commercial advantages — it
provides easy and quick access to both farmers as well as consumers.
• He says a major benefit of aquaponics is the shelf-life of the products. “Our
products last three to four times longer than those produced from regular
cultivation. The production from aquaponics is 10 times more than that from
traditional farming,” he explains, adding, “I have 1,000 tomato plants in the
farm, and a single plant, I get eight to nine kilograms of tomatoes.

12. FUTURE ASPECTS
• Aquaponics has the potential to revolutionize modern agriculture by addressing
key challenges and inefficiencies in traditional farming methods
• As the water level is decreasing day by day , it can become the most useful
method crop and fish production.
• Its closed-loop system conserves water, reduces waste, and offers a sustainable
means of producing both fish and vegetables
