Presentation Transcript

  1. Lecture 7.7: Meat & Fish Agribusiness Chapter 11

  2. High-Density Animal Farming • Concentrated Animal Feeding Operations (CAFO) • Large indoor/outdoor operations • Maximum output • Minimize land costs • Mass crowding/minimal movement • Improve feeding efficiency

  3. CAFO Consequences • AnimalWaste Disposal • Manure lagoon overflows • Nutritionalsupplements • Antibioticresistance

  4. CAFO Alternatives • “Free-range” • More ethical • Less likely to spread disease • No antibiotics • Wastes dispersed evenly •  requires more land •  meat is more expensive

  5. Harvesting Fish & Shellfish • Aquaculture

  6. The Global Trend

  7. Commercial Extinction

  8. Current Fishing Methods

  9. Technology>>>Regeneration of Fish Stocks • Sonar-what is there below you? • GPS -return to the exact area! • Drift Nets-everything! • Long Lines-Swordrish/Sharks • Trawler Bag Scallops/Shrimp • Purse-seine--salmon/Tuna

  10. Fisheries of the World- Problems Tragedy of the Commons Overharvesting OceanPollution Aquaculture

  11. Bycatch

  12. AlteringEcological Roles Cod –v- dogfish

  13. Fishery Management Plans • Sustainable Fisheries Act (1996) • Species-sustainability approach • Protect critical habitat for commercial and non-target species • “Close” fisheries because they have “collapsed” Magnuson Fisheries Conservation Act-1977 • 8 Fishery Management Councils • New England  • North Pacific  • Mid-Atlantic  • Pacific Fishery  • South Atlantic  • Western Pacific  • Gulf of Mexico  • Caribbean 

  14. Successful Fisheries Management • Individual Transferable Quota’s (ITQ’s) • Set the total allowable catch • Distribute/sell quotas to fisherman/corporations • Secure right to catch your quota so it nullifies the better-technology race

  15. Fishing Regulation Outcome • limit the number of boats • catch quotas (limit the allowable catch) • limit allowable size of catch • gear restrictions • exclusion zones

  16. Aquaculture • Aquaculture • Growing of aquatic organisms for human consumption • Great potential to supply food • Locations of fisheries may hurt natural habitats • Produce waste that pollutes adjacent water

  17. as of 1998 • Source Auburn University

  18. Farming Fish • YIELD! (so create optimal conditions) • GM species (salmon example) • Catchfish to feed fish (unless herbivorous) • diseases---> antibiotics • wastedisposal • excrement and off target food pellets pumped out • ESCAPE?

  19. Ex1: Thailand Shrimp farms • Habitat Media: “Farming the Seas” • Coastal development • CLEAR Mangrove forests • Humans in Buffer Zones • VIDEOS!

  20. Marine Sanctuaries

  21. Hawaii Islands Named World's Largest Marine Sanctuary James Owen for National Geographic News June 15, 2006 A scattered chain of Hawaiian islands today became the largest marine sanctuary in the world. Surpassing Australia's Great Barrier Reef, the Northwestern Hawaiian Islands (NWHI) will form part of a 140,000-square-mile (362,580-square-kilometer) protected area nearly the size of California.
