9 Commercial Set Net Fishery

10 Masu, or cherry, salmon

11 Sakhalin Taimen

12 Logging

13 Oil and Gas

14 Poaching (subsistence)

15 Poaching (commercial)

16 IUCN’s mission and role IUCN is committed to reversing declining biodiversity trend by 2010 Red List tracks status of species using a variety of criteria IUCN Salmonid Specialist Group

17 General approach Reach consensus on units for listing following IUCN guidelines (global population and subpopulations) Assemble relevant data and apply IUCN criteria Estimate risk of extinction, add to IUCN Red List Progress to date:  Sakhalin Taimen (added 2006)  Sockeye salmon (submitted 2007)  Chinook salmon (planned early 2008)  Steelhead/coho/masu/chum/pink (by IUCN Barcelona Congress, Fall 2008)

18 Range and Status: Sakhalin taimen - 2006 RL - Critically Endangered

19 Range and Status: Sockeye salmon 2008 RL

20 Key threats for sockeye salmon Practice of mixed-stock fishing Poor marine survival rates Global climate change, possibly linked to increased incidence of disease Effect of enhancement is recognized, but magnitude of effect remains uncertain In many specific cases, causes of decline are unknown

21 RFE and Sustainable Salmon Fisheries Region of high salmon biodiversity with generally intact habitat, limited hatchery influence Appropriate fishing technology (set nets) Three key things to consider:  Identify and describe salmon biodiversity  Develop a means to track trends (abundance and productivity)  Institute market incentives that controls fishing pressure and protects habitat
