Book Description
Fishery agency mismanagement, coupled with natural trends working against salmon, has brought Northwest salmon runs to historic lows. Charged by law to protect salmon, yet promote salmon harvest, fishery agencies do not even count how many Columbia Basin salmon are caught and killed for consumption, or measure the cost-effectiveness of salmon hatcheries. The most basic biological facts about salmon are politicized, as fishery officials misrepresent the effects of dams on salmon to extract federal funding from the Bonneville Power Administration. The result? A $3 billion program focused on fine-tuning fish passage at mainstem Columbia and Snake River dams that fails to recover salmon, because there is no evidence that those dams are a limiting factor in salmon recovery. Packed with hundreds of specific citations to the most recent scientific papers and reports, The Great Salmon Hoax is a valuable resource for anyone wanting to understand how salmon recovery efforts have gone awry, and how we can craft a rational, scientific program for salmon recovery that will bring significant numbers of salmon back to the Pacific Northwest.

Book Description
This new definitive volume on fish auditory systems will interest investigators in both basic research of fish bioacoustics as well as investigators in applied aspects of fisheries and resource management. Topics cover structure, physiology, localization, and acoustic behavior as well as more applied topics such as using sound to detect and locate fish.

Book Description
The New York Times–bestselling classic set amid the mountains and streams of early twentieth-century Montana, “as beautiful as anything in Thoreau or Hemingway” (Chicago Tribune). When Norman Maclean sent the manuscript of A River Runs Through It and Other Stories to New York publishers, he received a slew of rejections. One editor, so the story goes, replied, “it has trees in it.” Today, the title novella is recognized as one of the great American tales of the twentieth century, and Maclean as one of the most beloved writers of our time. The finely distilled product of a long life of often surprising rapture—for fly-fishing, for the woods, for the interlocked beauty of life and art—A River Runs Through It has established itself as a classic of the American West filled with beautiful prose and understated emotional insights. Based on Maclean’s own experiences as a young man, the book’s two novellas and short story are set in the small towns and mountains of western Montana. It is a world populated with drunks, loggers, card sharks, and whores, but also one rich in the pleasures of fly-fishing, logging, cribbage, and family. By turns raunchy and elegiac, these superb tales express, in Maclean’s own words, “a little of the love I have for the earth as it goes by.” “Maclean’s book—acerbic, laconic, deadpan—rings out of a rich American tradition that includes Mark Twain, Kin Hubbard, Richard Bissell, Jean Shepherd, and Nelson Algren.” —New York Times Book Review Includes a new foreword by Robert Redford, director of the Academy Award–winning film adaptation

Book Description
With more than 29,000 species, fishes are the most diverse group of vertebrates on the planet. Of that number, more than 12,000 species are found in freshwater ecosystems, which occupy less than 1 percent of the Earth’s surface and contain only 2.4 percent of plant and animal species. But, on a hectare-for-hectare basis, freshwater ecosystems are richer in species than more extensive terrestrial and marine habitats. Examination of the distribution patterns of fishes in these fresh waters reveals much about continental movements and climate changes and has long been critical to biogeographical studies and research in ecology and evolution. Tim Berra’s seminal resource, Freshwater Fish Distribution,maps the 169 fish families that swim in fresh water around the world. Each family account includes the class, subclass, and order; a pronunciation guide to the family name; life cycle information; and interesting natural history facts. Each account is illustrated, many with historical nineteenth-century woodcuts. Now available in paperback, this heavily cited work in ichthyology and biogeography will serve as a reference for students, a research support for professors, and a helpful guide to tropical fish hobbyists and anglers.

Book Description
Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Book Description
As the human population increases and nations become more industrialized, the habitat and water quality required for the survival of fish continues to decline. In addition to these environmental factors, fish populations are directly or potentially affected by harvesting, enhancement programs and introgression with hatchery-propagated or transgenic fish. To our knowledge no other scientific meeting has been assembled to consider the breadth of the problem, to review the technology that is presently available for the preservation of the germ plasm of salmonid stocks and to identify the scientific advances that are required to overcome the problems. Because many salmonids have spawning grounds within the confines of a specific region or county but will spend a large portion of their life cycle within the territorial waters of other countries or in the open ocean, the preservation of unique genes or gene pools in these animals requires international cooperation. This scientific meeting has provided a forum in which to discuss the problems, evaluate the present methods or technology for addressing the problems and suggest new directions or innovations that need to be implemented. During this meeting we limited our discussion to salmonid fishes. However, the general conclusions about the factors that affect the population dynamics of fish stocks and the technical aspects concerning the preservation of germ plasm will be applicable to other fish species.
