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
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)
Range and Status:Sakhalin taimen - 2006 RL - Critically Endangered
Range and Status: Sockeye salmon
2008 RL
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
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
