Polyculture and Integrated Tilapia Farming Systems - Kuala Lumpur, Malaysia Presentation Transcript

  • 1. POLYCULTURE AND INTEGRATED TILAPIA FARMING SYSTEMSKevin Fitzsimmons, Cesar Hernandez, Jason Licamele, Rafael Martinez University of Arizona Kuala Lumpur, Malaysia November 4, 2009
  • 2. Global food crisis Rapidly increasing population Diversion of foods to bio-fuels Increased costs for water, fertilizer, fuel Multiple demands for farmland (urban sprawl, industrial and mining, solar and wind generation, wildlife conservation, watershed protection, global warming, etc.) Need for second generation biofuels
  • 3. Need new model for food production Green Revolution – huge increase in food production, but heavy reliance on irrigation, fuel and fertilizer Blue Revolution – almost 50% of seafood is farm raised, but many environmental impacts (effluents causing eutrophication, algae blooms, cage and raft conflicts with other users in oceans, bays and lakes)
  • 4. Historical perspective Traditional farming around the world integrated livestock and crops East and South Asian farmers have long tradition of integrating agriculture and aquaculture Asian sustainable farming systems support huge populations Fish – vegetable – rice (complex carbohydrate) diet is recommended by most nutrition experts
  • 5. Historical perspective Modern agriculture cannot follow Asian model of small-farm integrated systems (gardening) We need an industrial version merging aqua- and agri- cultures Taking the best of the Green and Blue Revolutions
  • 6. Green Revolutions weaknesses are Blue Revolutions needs and vice-versa1. Fertilizer demand 1. Aquaculture effluent rich in N and P2. Increase in irrigation 2. Fish grow well in irrigation water3. Chemical fertilizers 3. Fish wastes are slow pollute groundwater release, organic4. Industrial crops with by- 4. Fish feeds need products alternatives for fish meal and oil
  • 7. Tropical Inland Integrated System Tilapia oil palm, rice, sugar cane
  • 8. Tilapia and citrus in Hainan, China
  • 9. Arid Integrated SystemsTilapia Grapes, wheat, olives, barley, sorghum, cotton, melons, peppers Safford, AZ Marana, AZ

  • 17. Arid Integrated Systems Tilapia cages to cotton Tilapia to hydroponics Ak Chin, AZ University of Arizona
  • 18. AquaponicsTilapia and lettuce
  • 19. RESULTS Effluent nutrient values 0.07 mg/L NH3, 0.321 mg/L NO2, 21.2 mg/L NO3, 0.17 mg/L total P Fertilizer value about 43 kg/ha N and 0.34 kg/ha P

  • 22. Use of Tilapia/shrimp sludge as a soil amendment for tomatoes Chad King Environmental Research Lab University of Arizona
  • 23. Research Design Collected and dried fresh sludge from a tilapia/shrimp farm in western Arizona, USA Treatments of 5, 10 and 20% sludge application by volume, 402, 805 and 1,610 g/plant Mechanically mixed shrimp sludge and potting soil mix (concrete sand, mulch, vermiculite) Randomly transplanted and arranged 28 ‘Roma’ tomato starts in a greenhouse, one plant per pot Each plant received 4 L of water daily, over four applications by drip irrigation Response measured in mass of tomatoes produced
