Salmonid Specialist Group


Outline
Outline

  • Pacific Salmon Conservation Assessment, PSCA

  • Key threats to salmon in the Russian Far East

  • IUCN World Conservation Union Assessments of Extinction Risk (species and populations)















Iucn s mission and role
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
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:Sakhalin taimen - 2006 RL - Critically Endangered



Key threats for sockeye salmon
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
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
