Book Description
The symposium "Pacific Salmon and Their Ecosystems: Status and Future Options',' and this book resulted from initial efforts in 1992 by Robert J. Naiman and Deanna J. Stouder to examine the problem of declining Pacific salmon (Oncorhynchus spp.). Our primary goal was to determine informational gaps. As we explored different scientific sources, state, provincial, and federal agencies, as well as non-profit and fishing organizations, we found that the information existed but was not being communicated across institutional and organizational boundaries. At this juncture, we decided to create a steering committee and plan a symposium to bring together researchers, managers, and resource users. The steering committee consisted of members from state and federal agencies, non-profit organizations, and private industry (see Acknowledgments for names and affiliations). In February 1993, we met at the University of Washington in Seattle to begin planning the symposium. The steering committee spent the next four months developing the conceptual framework for the symposium and the subsequent book. Our objectives were to accomplish the following: (1) assess changes in anadromous Pacific Northwest salmonid populations, (2) examine factors responsible for those changes, and (3) identify options available to society to restore Pacific salmon in the Northwest. The symposium on Pacific Salmon was held in Seattle, Washington, January 10-12, 1994. Four hundred and thirty-five people listened to oral presentations and examined more than forty posters over two and a half days. We made a deliberate attempt to draw in speakers and attendees from outside the Pacific Northwest.

Book Description
Protected marine species have populations that are depleted, decreasing, or are at-risk of extinction or local extirpation. As of 2015 The International Union for the Conservation of Nature, a global environmental organization, lists approximately 737 marine species worldwide that are considered at risk of extinction. Many are provided legal protection through national laws requiring research and management measures aimed at recovering and maintaining the species at a sustainable population level. Integral to the policy decision process involving the management and recovery of marine species is the consideration of trade-offs between the economic and ecological costs and benefits of protection. This suggests that economics, at its core the study of trade-offs, has a significant role. In the U.S. a somewhat traditional use of economics in protected species research and management has involved cost minimization or cost-effectiveness analyses to help select or prioritize conservation actions. Economic research has also provided estimates of public non-market benefits of recovering species, which can be used in larger management frameworks such as ecosystem based management and coastal and marine spatial planning. Inherent in much of this research, however, are complex biological and ecological relationships in which varying degrees of scientific uncertainty are present. Addressing this type of uncertainty can affect the economic outcomes related to protected species. For example, recent work suggests that increasing scientific precision in biological sampling and models can greatly affect the magnitude of economic benefits to commercial fisheries, while other research suggests that public non-market benefits of species recovery are sensitive to uncertainty about baseline population estimates. Previous research has illustrated the importance of understanding the biological, ecological, and economic aspects of protected species management and recovery. In this research topic we synthesize current protected marine species economic research and expand the discussion on present and future challenges related to protected species economics. The series of manuscripts brings together an array of prominent researchers and advances our understanding of the ecological and economic aspects of managing and recovering protected marine species.
