Abstract
The rich biological diversity in salmonids has been recognized for centuries and has been a central premise in managing salmon fisheries in this century (the “Stock Concept”). But recently, as in many other biological resources (FAO, 1981; Oldfield, 1989), increased concern has been expressed about the loss of biological diversity and the impact of harvest management on Pacific salmon. Management of Pacific salmon (Oncorhynchus sp.) is probably as rich in social, economic, and political issues as its resource base is biologically, and the scope of this issue continues to expand. Multiple resource management principles, such as sustainable economic development (WCED, 1987), will increase harvest and environmental issues involved in salmon management decisions. Evidence for global climate changes increases uncertainty about future salmon production. Litigation is increasingly used to protect specific interest groups. Unfortunately, in many salmon management decisions, the non-biological interests have taken precedence over the biological resource (Wright, 1981; Fraidenburg and Lincoln, 1985; Walters and Riddell, 1986). Each of these may have been a responsible decision, but in aggregate they create a serious biological problem through the gradual but steady erosion of biological diversity. An adage for similar problems in other fields of resource management is The Tyranny of Small Decisions. However, decisions favoring biological conservation are becoming more frequent, even though their effects on resource use, other resources, and communities are becoming more controversial.
