Sustainable Fisheries and Human Impact on Marine Resources

This comprehensive resource delves into the impact of human activities on marine ecosystems, specifically focusing on sustainable fishing practices and utilization of marine resources. Explore the intricate balance of marine life and the influence of human intervention on fisheries, energy consumption, and chemical usage in the ocean. Learn about the importance of conserving marine resources for future generations and the concept of maximum sustainable yield in fisheries management.

  1. Marine Resources and Human impact on the ocean

  2. Marine resources • Chemicals • Energy • Fisheries

  3. Beer/Wine/ Vinegar -accelerates and improves clarity. Chocolate Milk Drink -stabilizes and improves viscosity. Ice cream -prevents ice crystals formation. -enhances excellent mouth feel. Flans/Dessert Gel -enhances flavor release and excellent mouth feel Sauces and Dressings -thickens and improves viscosity. Beef Patty -substitutes fat, retains moisture and increase yield. Luncheon Meat -prevents fat separation serves as a meat extender. Poultry and Ham -controls dehydration of frozen poultry, enhances juiciness and increase yield. Petfood Canned meat and fish -gelling and stabilizing agent. Moist, solid petfood –binder Toothpaste –stabilizer Air freshener -gelling agent. Natural products

  5. Fisheries – A renewable resource? • What’s a fishery? – a concerted human effort to catch species of fish for human use and consumption • Includes both finfish and shellfish (crustaceans and mollusks) Where are the most productive fisheries?

  6. Note: china’s catch doesn’t include Taipei or Hong Kong 293,191,054,000 pounds

  7. 293,191,054,000 pounds

  8. Why fish? Food and economics

  9. 16% of global human protein consumption Higher for costal and island nations – Japan, Iceland, Caribbean etc.

  10. 9,505,000,000 pounds of fish Includes imports and exports What we use fisheries for…

  11. Coos Bay/Charleston 2003 24.7 million pounds

  12. Coos Bay/Charleston – 15.9 million dollars (all that money spent probably at the local Wal-mart…ugh)

  13. Deadliest catch

  14. How could we possible maintain a fishery at these numbers? Ahhhhh… the Theory of Surplus Production

  15. Some considerations first… -biological resources -biological interactions -fish recruitment and survival depends upon food availablity/competition, predation and disturbance -age and size structure of stock

  16. The ever elusive MSY (maximum sustainable yield) aka TAC – total allowable catch

  17. North Atlantic Cod fishery

  18. An IHOP ad: OOOOOHHHHH NOOOOOOOOOO!
