**Symposium on Hatchery Supplementation and the Fitness of Natural
Salmon Populations**

**3 -- 4 June 2008**

**Museum of History and Industry**

McCurdy Park\
2700 24th Ave East\
Seattle, WA 98112-2099

NOAA Fisheries [Northwest Fisheries Science
Center](http://www.nwfsc.noaa.gov/) and the [Columbia River Inter-Tribal
Fish Commission](http://www.critfc.org/) are hosting a symposium on
hatchery supplementation and its effects on the fitness of wild salmon
populations. The symposium is motivated by two recent reports on salmon
supplementation -- a
[report](http://www.nwcouncil.org/library/isrp/isrp2005-15.htm) by the
Independent Science Advisory Board
([ISAB](http://www.nwcouncil.org/fw/science.htm)) recommending more
coordinated monitoring of supplementation programs, and a report by an
[Ad Hoc Supplementation Work
Group](http://www.nwcouncil.org/fw/program/2008amend/view.asp?id=95)
that provided specific recommendations for supplementation monitoring in
the Columbia River Basin. The purpose of the symposium is to provide a
forum for fishery managers, policy makers, scientists, and the public to
learn about and discuss recent research results related to these
recommendations. The event is free and open to the public.
