  1. Aquaponics Ryan Sultana

  2. What is Aquaponics? …‘Aquaponics is the art of growing food with fish poop’, Anonymous “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 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.

  3. History Chinampas Built by Incas and Aztecs Between 14th -16th century A.D

  4. History Paddy Fields In China and Thailand Since the 6th Century

  5. History Barrays Built by Cambodians In Angkor, India

  6. Hydroponics – Growing in water… The Raft System also known as Deep Water Culture

  7. Hydroponics – Growing in water… The Raft System also known as Deep Water Culture

  8. Other Systems • NFT – Nutrient Film Technique • Wick System • Ebb and Flow • Drip System • Aeroponics Nutrient Film Technique

  9. Other Systems Aeroponics

  10. Aquaponics

  11. A Sustainable System SUN 3 1 2

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

  14. Why Aquaponics? 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

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

  16. Other Possibilities 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

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

  18. Other Possibilities Taken from the movie ‘Sunshine’

  19. Thank You “The ultimate goal of farming is not the growing of crops, but the cultivation and perfection of human beings.” ― Masanobu Fukuoka, The One-Straw Revolution Ryan Sultana
