Intro to aquaponics
- 1. Aquaponic Gardening By: Shane Noel
- 2. What is Aquaponics? • Aquaponics is a combination of agriculture and aquaculture in which the waste produced by fish is converted into nutrients for plants in a soil-less medium. Source: Antkneebrowns aquaponics blog
- 3. Environmental Impact on traditional agriculture
- 4. Current Obstacles • Monocultures are eroding biodiversity in ecosystems. • Chemical pesticides and fertilizers are polluting soil, water, and air, harming both the environment and human health. – In 1998, the world used 137 million metric tons of chemical fertilizer – Between 1950 and 1998, worldwide use of fertilizers increased more than 10-fold . • Soil is eroding faster than it can be replenished, diminishing land fertility and nutrient availability. • Water is being consumed at unsustainable rates.

- 7. Advantages of Aquaponics • Lower utility consumption (water and power). • Faster rates of growth with an increase in quality while producing less waste. • Higher vegetation density than traditional agriculture. • Less maintenance due to reduction of pests and ease of upkeep. • More appropriate for urban gardening as population increases.
- 8. Aquaponics Advantages • Closed-loop operation allows for wastewater recycling where up to 98% less water is consumed compared to traditional farming • Fish waste derived nutrients eliminate the need of synthetic fertilizers • High vegetation density results in less land use, and preserves soil quality http://aquaponicsplan.com/creating-a- sustainable-food-supply-through- aquaponics/
- 10. Methods of delivery • DWC • Krackty • Ebb and flow • Aeroponics • Drip system • NFT (nutrient film technique)
- 11. Soilless media • Vermiculite • Perlite • Rockwool • Expanded clay pellets • Coconut husk
- 12. Lighting for indoor growing MH (metal Halide) HPS (High pressure sodium) CFL (Compact florescent) L.E.D Lighting
- 13. Aquatic Life Goldfish • Easy Starter fish • Inexpensive Beta • Great for kids • Inexpensive Tilapia • Most common fish used • Fast growing Artic char • Temperature resistant • Can live in high density
- 14. Vegetation Food Tomato Mint Lettuce Kale Green onion House Plants sage Ornamental flowers Catnip

- 17. Benefits to the Community • Independent production of produce that saves households and businesses money. • Early adopters of emerging technology. • Organic based food. • Simplicity in design makes it easy to start – even on the small scale.
