Millions upon millions of salmon and steelhead once filled California streams, providing a plentiful and sustainable food resource for the original peoples of the region. But over the years, dams and irrigation diversions have reduced natural spawning habitat from an estimated 6,000 miles to fewer than 300. River pollution has also hit hard at fish populations, which within recent decades have diminished by 80 percent. One species, the San Joaquin River spring chinook, became extinct soon after World War II. Other species are nearly extinct. This volume documents the reasons for the decline; it also offers practical suggestions about how the decline might be reversed. The California salmon story is presented here in human perspective: its broad historical, economic, cultural, and political facets, as well as the biological, are all treated. No comparable work has ever been published, although some of the material has been available for half a century. In the richly varied contributions in this volume, the reader meets Indians whose history is tied to the history of the salmon and steelhead upon which they depend; commercial trollers who see their livelihood and unique lifestyle vanishing; biologists and fishery managers alarmed at the loss of river water habitable by fish and at the effects of hatcheries on native gene pools. Women who fish, conservation-minded citizens, foresters, economists, outdoor writers, engineers, politicians, city youth restoring streambeds-all are represented. Their lives-and the lives of all Californians-are affected in myriad ways by the fate of California's salmon and steelhead.

Aquaculture exemplifies the ongoing global struggle to strike a sustainable balance between the conflicting needs of a rapidly increasing world population, human health, ecosystem health, the welfare of wild and domesticated animals, and the economic principles of globalized economies. On the one hand, aquaculture has great potential for providing us with a healthy and nutritious food supply whilst alleviating pressure on captive fisheries and reducing fisheries-induced habitat destruction, overfishing, genetic modification of wild populations, and wholesale waste of bycatch. On the other hand, aquaculture relies heavily on clean water, an increasingly precious (and dwindling) resource that is subject to intense pressure of being used for many competing objectives. This concise primer introduces students to the basic concepts, opportunities, and challenges of aquaculture with an emphasis on ecological considerations. It provides a critical assessment of current aquaculture practices from a broad, interdisciplinary perspective and from the standpoint of how best to align the two major (and often conflicting) goals of future aquaculture development: minimizing reliance on ecosystem services whilst maximizing productivity. A Primer of Ecological Aquaculture provides an accessible and authoritative overview for a wide range of undergraduate majors ranging from biology, engineering, and environmental policy to business and management. It will also appeal to a more general academic audience who wish to gain a current overview of the field.

The Fishes of the Western North Atlantic series, which began publication in the 1940s by Yale University's Sears Foundation for Marine Research, was from its beginnings conceived to synthesize and make accessible the wealth of information in widely scattered published accounts of the fish fauna of the region for both the layman and the specialist, presenting critical reviews rather than compilations. These reference works are still considered valuable and of interest today to both general audiences and the academic community. As described in the Preface to the first volume, the series was "written on the premise that it should be useful to those in many walks of life-to those casually ... interested ..., to the sportsman ..., to the fisherman ..., as well as to the amateur ichthyologist and the professional scientist." These books remain authoritative studies of the anadromous, estuarine, and marine fishes of the waters of the western North Atlantic from Hudson Bay southward to the Amazon, ranking as primary references for both amateurs and professionals interested in fishes, and as significant working tools for students of the sea.

An authoritative guide to the identification, systematics, distribution, and biology of the thirty-eight species of the Order Beloniformes in the western North Atlantic Ocean The final volume in the Fishes of the Western North Atlantic series covers the Beloniformes, a diverse order of fishes containing six families and at least two hundred and thirty extant species found worldwide in marine and freshwater environments. This excellently illustrated, authoritative book describes the thirty-eight species of beloniform fishes-needlefishes, sauries, halfbeaks, and flyingfishes-that live in the western Atlantic Ocean. Compiled from new revisions, original research, and critical reviews of existing information, this tenth book in the series completes a major reference work in taxonomy and ichthyology for both amateurs and professionals, and all students of the sea.

The Klamath River basin, which spans parts of southern Oregon and northern California, has been the focus of a prominent conflict over competing uses for water. Management actions to protect threatened and endangered fish species in the basin have left less water available for irrigation in dry years and heightened tensions among farmers and other stakeholders including commercial fishermen, Native Americans, conservationists, hunters, anglers, and hydropower producers. This National Research Council book assesses two recent studies that evaluate various aspects of flows in the Klamath basin: (1) the Instream Flow Phase II study (IFS), conducted by Utah State University, and (2) the Natural Flow of the Upper Klamath Basin study (NFS), conducted by the U.S. Bureau of Reclamation (USBR). The book concludes that both studies offer important new information but do not provide enough information for detailed management of flows in the Klamath River, and it offers many suggestions for improving the studies. The report recommends that a comprehensive analysis of the many individual studies of the Klamath river basin be conducted so that a big picture perspective of the entire basin and research and management needs can emerge.

Ohio's original heavily forested landscape included glacial lakes, large rivers, and streams that teemed with an abundant variety of fish, most of which remain resident today. Native Fishes of Ohio documents the more than 130 species originally found in the state and describes how their aquatic habitats have evolved as a result of agriculture and industrial development. Naturalist Dan Rice and photographer Gary Meszaros draw upon more than 40 years of fieldwork and recent hands-on experience to detail the natural history of each species of Ohio fish. The authors provide field identification characteristics and describe each fish's habitat, ecology, and distribution. The book is profusely illustrated with Gary Meszaros's spectacular color photographs of live specimens in their natural environment, a resource unique to this volume. The range of shapes and vivid colors will give the reader insight into the fascinating world of the state's native fishes. An ideal resource for the non-specialist, Native Fishes of Ohio will interest nature lovers, teachers, and anglers and is a must for every Ohio school and public library.
