  1. Aquaponics

  2. What is aquaponics? • A system that grows fish and plants together

  3. Items Needed1. Fish Tank2. Grow Bed3. Water Pump4. Aerator5. Tubing

  4. What do plants and fish need to live? Plants • Light • Water • Carbon Dioxide • Nitrates (nutrients) • Fish • Food • Clean Water • Oxygen

  5. What do plants make? • Oxygen and Sugars through photosynthesis • Clean Water

  6. What do fish make? • Waste in the form of ammonia • Carbon dioxide through respiration

  7. Carbon Cycle

  8. Basic Carbon Cycle in Aquaponics • 1. Plants take in carbon dioxide • Plants produce oxygen, and sugars (plant biomass) through photosynthesis • 2. Fish consume sugars and breath in oxygen • Fish produce carbon dioxide through respiration • Complete!

  9. Nitrogen Cycle • How does ammonia turn into nitrates?

  10. The Nitrogen Cycle

  11. Fish and Plant Nitrogen Cycle • 1. Fish eat food • 2. Waste is rich in ammonia NH4 • 3. Ammonia converted to Nitrite NO2 by nitrosonomas • 4. Nitrite converted to Nitrates NO3 by nitrospira • 5. Nitrates used by plants a nutrients • 6. Plant material eaten by fish • * Dead plant and animal material decomposes and releases ammonia also

  12. Nitrogen Cycle in Aquaponics

  13. How it works

  14. Aquaponic Benefits • Symbiotic relationship between plants and fish (both thrive due to one another) • Reduction in waste (polluted fish water is used) • 90% REDUCTION in water use vs. conventional farming techniques • Minimal need for land • Supports Locavorism (reduces GHG emissions) • Produces an organic food source

  15. Disadvantages to aquaponics • High start up costs • Systems are not one size fits • Needs constant monitoring • May not be aesthetically pleasing in your living room • Difficult to find fish

  16. History of Aquaponics

  17. Thoughts… Questions • Is aquaponics a solution for our health problems?

  18. Items to know for your quiz • What is aquaponics? • How does aquaponics work? • What types of fish can you raise? • What types of vegetables can you raise? • How do plants and fish live symbiotically in regards to the carbon and nitrogen cycles? • What is the nitrogen cycle and how does it work? • What are the pros and cons of aquaponics? • What ancient citizens utilized aquaponics and how? • What is Sweetwater organics and what do they do?
