Lecture 7.7: Meat & Fish Agribusiness

Chapter 11


High density animal farming

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


Cafo consequences

CAFO Consequences

  • AnimalWaste Disposal

    • Manure lagoon overflows

  • Nutritionalsupplements

  • Antibioticresistance


Cafo alternatives

CAFO Alternatives

  • “Free-range”

    • More ethical

  • Less likely to spread disease

    • No antibiotics

  • Wastes dispersed evenly

  •  requires more land

  •  meat is more expensive


Harvesting fish shellfish

Technology regeneration of fish stocks

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

Fishery management plans

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 


Successful fisheries management

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


Fishing regulation outcome

Fishing Regulation Outcome

  • limit the number of boats

  • catch quotas (limit the allowable catch)

  • limit allowable size of catch

  • gear restrictions

  • exclusion zones


Aquaculture

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

Farming fish

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?


  • Ex1 thailand shrimp farms

    • Habitat Media: “Farming the Seas”

    • Coastal development

    • CLEAR Mangrove forests

    • Humans in Buffer Zones

    • VIDEOS!


    Marine sanctuaries

    Marine Sanctuaries


    Lecture 7 7 meat fish agribusiness

    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.
