AQUAPONIC FOOD PRODUCTION
MAKING FOOD SECURITY… …YOUR BUSINESS
AQUAPONICS – THE CONCEPT
Scientific DefinitionA revolutionary system that features a symbiotic
relationship where fish waste is used to nourish the crops using organic hydroponic techniques.
Food Production SystemCrops, Freshwater Fish, Freshwater Crustaceans
Takes the best of both Aquaculture and HydroponicsNaturally occurring controlled ecosystem approachEliminates wastage through re-circulation
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

YCLE
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
GROW BED SIPHON
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
VERTICAL AQUAPONICS
Nutrient Film Technique
PVC Towers or Stackable Pots
Media Hydroton Coir Mix
Advantages Continuous water supply
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
PRODUCE QUALITY
AQUAPONIC FARMS
GREEN ACRE AQUAPONIC FARM, FLORIDA
AQUAPONIC FARMS
PILOT SYSTEM – FIRST WEEKS
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
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
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
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
PRODUCTIVITY RATIO - ESTIMATION
Farm Size Vegetables Fish
1.8m x 2.5m (1) 400 45 kgs
3m x 6m (1) 1,100 180 kgs
6m x 9m (2) 3,600 635 kgs
30m x 30m (2) 60,000 10,400 kgs
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
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
