  1. The Global Fisheries Crisis: Ecological, Economic, and Social Dimensions Nicolas Gutierrez, Olaf Jensen, Michael Melnychuk, & Suresh Sethi with Trevor Branch and Daniel Schindler UW School of Aquatic and Fishery Sciences

  2. Outline Status of global fisheries Drivers of fishery development Management options for sustainable fisheries: Catch Shares Co-Management

  3. Impacts of fishing NEW TARGET OLD TARGET

  4. Current status

  5. Trends in fishery indicators

  6. Fishery development 1950-2004 development year = catch first reaches 25% of max annual catch No trend

  7. Harvest better opportunities first Fishing deeper Fishing smaller

  8. Fishing is a mature industry

  9. Effects of catch share systems Essington 2010, PNAS

  10. Europe South Africa Argentina New Zealand Australia US SE coast/Gulf of Mexico US NE coast Canada east coast Canada west coast US west coast US Alaska TAC with catch shares (n=35) Exploitation under different management types TAC only (n=71) Frequency Effort control (n=15) ± s.e. TAC with catch shares TAC only Effort control log of F : Fmsy ratio log of F : Fmsy ratio

  11. Catch shares align incentives of individual fishermen with management goals • Generally work with developed regulatory agencies • At the community level, how might incentives of a group of resource users be aligned with management objectives ? Giving stakeholders a lasting stake

  12. Fisheries Co-Management • Institutional arrangement where responsibility for resource management is shared between the government and user groups Modified from Ostrom 2009 Science

  13. Global Review • Success Score (SS): • ΣOutcomes = 8 • ~ 50% with SS ≥ 6 mean ± SE n = 121

  14. Keys for co-management success

  15. Conclusions • Many fisheries are overfished or collapsed, but many are healthy or recovered. • Pattern of profit-driven fishing evident at a global scale. Commercial fishing is now a mature industry. • We can achieve sustainable fisheries with appropriate management including catch shares and co-management.
