Generations ago, salmon were abundant from central California through Idaho, Oregon, and Washington to British Columbia and Alaska. Now they have disappeared from about 40 percent of their historical range. The decline in salmon numbers has been lamented for at least 100 years, but the issue has become more widespread and acute recently. The Endangered Species Act has been invoked, federal laws have been passed, and lawsuits have been filed. More than $1 billion has been spent to improve salmon runs-and still the populations decline. In this new volume a committee with diverse expertise explores the complications and conflicts surrounding the salmon problem-starting with available data on the status of salmon populations and an illustrative case study from Washington state's Willapa Bay. The book offers specific recommendations for salmon rehabilitation that take into account the key role played by genetic variability in salmon survival and the urgent need for habitat protection and management of fishing. The committee presents a comprehensive discussion of the salmon problem, with a wealth of informative graphs and charts and the right amount of historical perspective to clarify today's issues, including: Salmon biology and geography-their life's journey from fresh waters to the sea and back again to spawn, and their interaction with ecosystems along the way. The impacts of human activities-grazing, damming, timber, agriculture, and population and economic growth. Included is a case study of Washington state's Elwha River dam removal project. Values, attitudes, and the conflicting desires for short-term economic gain and long-term environmental health. The committee traces the roots of the salmon problem to the extractive philosophy characterizing management of land and water in the West. The impact of hatcheries, which were introduced to build fish stocks but which have actually harmed the genetic variability that wild stocks need to survive. This book offers something for everyone with an interest in the salmon issue-policymakers and regulators in the United States and Canada; environmental scientists; environmental advocates; natural resource managers; commercial, tribal, and recreational fishers; and concerned residents of the Pacific Northwest. 606 $aPacific salmon$zNorthwest, Pacific 606 $aFishes$xConservation$xSocial aspects$zNorthwest, Pacific 606 $aPacific salmon fisheries$zNorthwest, Pacific$xManagement 606 $aPacific salmon$xEffect of habitat modification on$zNorthwest, Pacific 615 0$aPacific salmon 615 0$aFishes$xConservation$xSocial aspects 615 0$aPacific salmon fisheries$xManagement. 615 0$aPacific salmon$xEffect of habitat modification on 676 $a597/.55 712 02$aNational Research Council (U.S.).$bCommittee on Protection and Management of Pacific Northwest Anadromous Salmonids. 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910965599103321 996 $aUpstream$94471433 997 $aUNINA
