Aquaponic Food Production

  1. 1. AQUAPONIC FOOD PRODUCTIONMAKING FOOD SECURITY… …YOUR BUSINESS
  2. 2. AQUAPONICS – THE CONCEPT Scientific Definition  A revolutionary system that features a symbiotic relationship where fish waste is used to nourish the crops using organic hydroponic techniques. Food Production System  Crops, Freshwater Fish, Freshwater Crustaceans Takes the best of both Aquaculture and Hydroponics  Naturally occurring controlled ecosystem approach  Eliminates wastage through re-circulation
  3. 3. SYSTEM COMPONENTS Aquaculture Tanks (Fish)  Food Safe UV Resistant Inert Round Poly Tanks (1000L +)  Fiberglass is also a long life option Grow Bed  3m x 1.3m x 0.30m (10ft x 4ft x 1ft)  Wooden structure with 0.5 mm Poly liner or Fiberglass Sump Tank  Integrated into the foundation of Grow Bed  Maintains water level in Fish Tanks  Shrimp & Prawn culture
  4. 4. SYSTEM WORKING
  5. 5. THE AQUAPONICS CYCLE
  6. 6. GROW BEDS Flexible Dimensions  Minimum Depth 0.30m  Wooden Structure or Fiberglass Growing Media (NO SOIL)  ¾” River bed Gravel or Hydroton  Aeration and Drainage Worms  Mineralization  Nitrogen Cycle Benefits  Bio-Filter for Solids  Physical Stability  Low Maintenance
  7. 7. GROW BED SIPHON
  8. 8. DEEP WATER CULTURE TROUGHS 0.3 m deep troughs with flowing water Wooden or Fiberglass structure Plants grown on floating Polystyrene sheets Benefits  Root Zone Temperature  Habitat for Crustaceans  Leafy plants do well  Ergonomics  pH, Temperature stability
  9. 9. VERTICAL AQUAPONICS Nutrient Film Technique PVC Towers or Stackable Pots Media  Hydroton  Coir Mix Advantages  Continuous water supply
  10. 10. AQUACULTURE (FISH) Tilapia (Most Successful)  Highly Tolerant to Water quality  Adapts well to differing temperature  Fingerling to 1.5 to 2 lbs (1kg) – 6 months Stocking Density  1 fish per 10 Litres of water Pelletized Fish Feed  Water Temperature  Daylight hours Fish Farming  Multiple size ratio  Regular harvest intervals
  11. 11. PRODUCE QUALITY
  12. 12. AQUAPONIC FARMS
  13. 13. GREEN ACRE AQUAPONIC FARM, FLORIDA
  14. 14. AQUAPONIC FARMS
  15. 15. PILOT SYSTEM – FIRST WEEKS
  16. 16. BENEFITS OF AQUAPONICS - CONCEPT 100% Organic and Chemical Free  Fish – Low Stress and Chemical Free  Crop Produce – 100% Naturally Grown Highly Sustainable Design  Low Irrigation  Low Energy Footprint  No Fertilizer/ Manure/ Soil/ Pesticide All Weather Solution  Root Zone Temperature  Water Circulation
  17. 17. BENEFITS OF AQUAPONICS - COMMERCIAL Niche Market  Cuisine Chefs and Gourmet Restaurants  Better than Organic  Health conscious consumers Food Security Solution of the Future  Safe + Sustainable + Controlled + Ecological  Low Cost + Simple Low Capital Expenditure  No High Tech Equipment  Locally available materials
  18. 18. SYSTEM CONSTRUCTION Large Components  Food Safe Inert Poly or Fiberglass Tanks  Construction grade Ply-Wood  0.51mm Polyethylene Liner (Perm = 0.015)  Food Safe PVC fittings and accessories Electrical Components  Medium grade water pumps (5000gph)  Air Diffuser pumps Biome Components  Red Wriggler or Garden Worms  Gravel or Hydroton  Seedling and Fingerling  Nitrifying Bacteria Culture
  19. 19. SYSTEM COSTING Construction/Material Cost Estimate  Wooden Structure – $10 per sq.m  Fiberglass tanks and troughs – $40 per sq.m  Hydroton Cost = $1000 per 1000L of growbed volume Labour Required  Skilled wood workers or Fiberglass casting  In house civil or mechanical engineer for system integration Estimated Earnings  $150,000 per year – 1500 sq.m  Seeding patterns, Water Quality, Harvest Planning
  20. 20. PRODUCTIVITY RATIO - ESTIMATIONFarm Size Vegetables Fish1.8m x 2.5m (1) 400 45 kgs3m x 6m (1) 1,100 180 kgs6m x 9m (2) 3,600 635 kgs30m x 30m (2) 60,000 10,400 kgs
  21. 21. SYSTEM MAINTENANCE Water pH = 6.5 to 7.0 (~ 6.6 to 7.4)  Tends to get High – Nitrification  Low – Anaerobic Nitrification  To Increase: Hydrated Lime (K or Ca Hydroxide)  To Decrease: Nitric or Phosphoric Acid Water Temperature = 22°C to 35°C Dissolved Oxygen = 5mg/L to 10mg/L Nitrogen Cycle  Nitrates = 5 to10 ppm  Nitrites < 2ppm,  Ammonia < 4 ppm
  22. 22. MILESTONES TIMELINE System Construction – week 1  Level Land, Grade and Concrete usage area  Trench and Raise for beds and plumbing  Construct Wooden frame and structure  Assemble Sections Fishless System Cycle – week 1 to week 3  Begin Seeding or transplant  Source Ammonia from Seaweed Extract  Balance pH, Nitrates, Ammonia  Prepare Nitrifying Bacteria Culture Introduce Fish – week 3 to week 4  Nitrates 5-10 ppm, Ammonia and Nitrites 0 ppm Harvest Begins – week 6 onwards
