Started marking steelhead in 1984

Began selective fisheries in ’86-87

Electronic Sampling

Challenges of Mass Marking and Selective Fisheries

• Modifications to the CWT system will be needed

• Direct samples of unmarked mortalities will not be available

• Cost of sampling will increase

• Increase in uncertainty on unmarked fish needs to be accounted for in management

• Fishery assessment models will need to be revised for management and conservation assessments

Benefits of Mass Marking and Selective Fisheries

• Great tool for identification of wild versus hatchery origin fish on the spawning grounds

• Essential tool for hatchery reform implementation including integrating hatchery and wild stock programs

• Can be used to enhance recreational and commercial fishing while protecting naturally spawning stocks

$770 Million to Washington salmon recovery

• 1997-2005: $770 Million: federal and state funds to direct salmon recovery– $360 M Operating $410 M Capital

• 77% to habitat• 10% to harvesting• 7% to hatcheries• 6% other salmon recovery efforts

Office of Program Research; Dec. 2004 Report to WA State Legislature

Improve the Fitness of Naturally Spawning Fish

• Reduce ratio of hatchery fish on spawning grounds

• Ensure wild spawning fish drive adaptation of the natural population and size of hatchery program.

• Increase harvest hatchery fish• Reduce harvest of natural fish
