  1. The Global Fisheries System Craig Harris Department of Sociology 27 October 2005

  2. The Global Fisheries System • The biophysical environment of the world’s major fisheries is global

  3. Sun + Nutrients = Forage • tropical areas of greatest insolation

  4. Sun + Nutrients = Forage • tropical areas of greatest insolation • ocean topography of continental shelves and banks

  5. Sun + Nutrients = Forage • tropical areas of greatest insolation • ocean topography of continental shelves and banks • riverine transport of nutrients from continental weathering

  6. Sun + Nutrients = Forage • tropical areas of greatest insolation • ocean topography of continental shelves and banks • riverine transport of nutrients from continental weathering • upwelling of nutrients

  7. The Global Fisheries System • The biophysical environment of the world’s major fisheries is global • Highly migratory and straddling stocks

  8. Major tuna ports of the world

  9. The Global Fisheries System • The biophysical environment of the world’s major fisheries is global • Highly migratory and straddling stocks • Introduction of exotics

  10. The Global Fisheries System • The biophysical environment of the world’s major fisheries is global • Highly migratory and straddling stocks • Introduction of exotics • Tilapia

  17. The Global Fisheries System • The biophysical environment of the world’s major fisheries is global • Highly migratory and straddling stocks • Introduction of exotics • Tilapia • Influences on water quality • Ozone depleting substances and the ozone hole • Persistent organic pollutants (POPs) • Riverine transport of pollutants • nutrients  anoxic zones
