Aquaponics is a sustainable system that integrates aquaculture and hydroponics. It allows fish and plants to be farmed together in a symbiotic environment where the fish waste fertilizes the plants and the plants help filter the water for the fish. Historically, aquaponics systems were developed by ancient civilizations like the Incas, Aztecs, and Cambodians. Modern aquaponics provides advantages like reduced labor, higher production rates, income from two products, and reuse of aquacultural waste. While the initial costs can be high, aquaponics is a more sustainable and efficient way to farm.

2. What is Aquaponics?
…‘Aquaponics is the art of
growing food with fish poop’,
Anonymous
An integration of two systems:
Hydroponics and Aquaculture
The process of growing food in an inert
medium by controlling and adding
nutrients but without soil
The cultivation of aquatic
animals or plants for food.
“Essentially, all life depends upon the soil ...
There can be no life without soil and no soil
without life; they have evolved together.”
Charles E. Kellogg

12. Why Aquaponics ?
Advantages
• Reduced labour
• Higher production rate
• Provides income from two separate products
• Aquacultural waste products are used
• A lot of current research and improvements
going on

13. Why Aquaponics ?
Advantages
• Less pests and diseases (if controlled)
• Reduced carbon footprint
• Reduced water loss
• Makes use of dead space
 Rooftops
 3-D vertical dimension
Vertical Drip
System Towers

14. Disadvantages
• High initial cost
 To fill up water tanks
 To build the system (Greenhouse, pumps etc.)
• Requires skill and know-how
• Constant monitoring of water parameters
• Pests and diseases can be devastating
• Limitations concerned with fish species reared
• Competitive market prices
Why Aquaponics?

15. Organic Aquaponics
• Natural fertilizer
• Natural minerals (snail shells)
• Good marketing – labelling
Other Possibilities
Use of Technology
• Smart phone applications
• Pipe blockage warning
• System automation
- Check out ‘urban aquaponics in
Oakland’ on youtube or Kijani Grows
on a search engine for more ideas -

16. Growing Indoors
• Can be used underground
and indoors
• Artificial lighting
• May be a life-saviour in
post-apocalyptic scenarios
• The Great Tennessee Pot
Cave drug bust
Other Possibilities

17. Growing Upwards
• Futuristic Concepts
• Growing locally
• Dedicated Skyscraper
Farms
• Makes use of limited
space availability
• Space missions
Other Possibilities
