Presentation Transcript
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
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

Fisheries of the World- Problems

Tragedy of the Commons

Overharvesting

OceanPollution

Aquaculture

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?

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.
