Available in PDF, EPUB and Kindle. Book excerpt: Stock Identification Methods, 2e, continues to provide a comprehensive review of the various disciplines used to study the population structure of fishery resources. It represents the worldwide experience and perspectives of experts on each method, assembled through a working group of the International Council for the Exploration of the Sea. The book is organized to foster interdisciplinary analyses and conclusions about stock structure, a crucial topic for fishery science and management. Technological advances have promoted the development of stock identification methods in many directions, resulting in a confusing variety of approaches. Based on central tenets of population biology and management needs, this valuable resource offers a unified framework for understanding stock structure by promoting an understanding of the relative merits and sensitivities of each approach. - Describes 18 distinct approaches to stock identification grouped into sections on life history traits, environmental signals, genetic analyses, and applied marks - Features experts' reviews of benchmark case studies, general protocols, and the strengths and weaknesses of each identification method - Reviews statistical techniques for exploring stock patterns, testing for differences among putative stocks, stock discrimination, and stock composition analysis - Focuses on the challenges of interpreting data and managing mixed-stock fisheries

Book excerpt: Published by the American Geophysical Union as part of the Water Science and Application Series, Volume 4. Declines in fish populations and the loss of riverine habitat from human demands on the environment intensify year by year. By considering why and how, and by proposing restoration methods and mitigation strategies, scientists respond forcefully to improve disturbed ecosystems. Geomorphic Processes and Riverine Habitat presents results from recent research in fluvial geomorphology related to the assessment and characterization of riverine and riparian habitat, and the response of biota to changes in their environment. As our understanding of formative processes and how humans occupy and shape the environment grows, we can minimize our impact while enhancing our ability to restore and rehabilitate degraded river systems. For scientists, researchers and students of riverine habitat.

Available in PDF, EPUB and Kindle. Book excerpt: Haa Leelk'w Has Aan' Saaxu / Our Grandparents' Names on the Land presents the results of a collaborative project with Native communities of Southeast Alaska to record indigenous geographic names. Documenting and analyzing more than 3,000 Tlingit, Haida, and other Native names on the land, it highlights their descriptive force and cultural significance. With community maps, tables, and photographs, this book will be invaluable for those seeking to understand Alaska Native geographic perspectives. As Tlingits from the Hoonah Indian Association explain in the book: "Long before Russian, French, Spanish, and British explorers mapped and named the mountains and bays of the Huna Tlingit homeland, we identified special places in our own vibrant, descriptive ways. Tlingit place names reflect important natural resources, ancestral stories, sacred places, and major geological and historic events. Our place names describe more than just inanimate locations for we perceive the mountains, glaciers, and streams to be as alive and aware as ourselves. Rather, they capture the history, emotions, and stories of our enduring relationship with a living, evolving landscape." "The new benchmark against which all future work will be measured." -Richard Dauenhauer, author of Russians in Tlingit America "Thomas Thornton and his Tlingit colleagues show how 'grandparents' names on the land' provide exquisite scaffolding for human ecologies in North America's far northwest--a moral universe inhabited by a community of beings in constant communication and exchange. This book will be a resource for the ages." -Julie Cruikshank, author of Do Glaciers Listen? Local Knowledge, Colonial Encounters, and Social Imagination "Restoring Tlingit placenames and their meanings will root our people back in place and decolonize the landscape, and Thornton has provided us with a fundamental tool to do exactly that. Sh t--oghaa xhat ditee--I am grateful." -Lance A. Twitchell, Xh'unei, University of Alaska Southeast Thomas F. Thornton is senior research fellow and director of the Environmental Change and Management Program at the Environmental Change Institute, School of Geography and the Environment, University of Oxford He is the author of Being and Place among the Tlingit.

Book excerpt: Intraspecific differences in erythrocyte antigens (blood types) were shown to occur in four species of Pacific salmon, the sockeye or red salmon (Oncorhynchus nerka), the chinook or king salmon (O. tshawytscha), the chum salmon (O. keta), and the pink salmon (O. gorbuscha). Antisalmon-erythrocyte sera prepared in rabbits and chickens were used after absorption of species-specific antibodies. Some of these blood types were shown to differ in their frequency of occurrence between different geographic races. In addition, isoimmunizations were prepared and at least eight different patterns of antigenic composition were displayed by the cells tested. These results indicate that considerable antigenic diversity exists in salmon. Reagents to detect valuable markers for the investigation of geographic races of salmon should be obtained through further research.

Available in PDF, EPUB and Kindle. Book excerpt: The importance of salmon to the Pacific Northwestâ€"economic, recreational, symbolicâ€"is enormous. 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 runsâ€"and still the populations decline. In this new volume a committee with diverse expertise explores the complications and conflicts surrounding the salmon problemâ€"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 geographyâ€"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 activitiesâ€"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 issueâ€"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.

Book excerpt: This book provides a good mix of both basic and applied topics in the hope that it will be useful and of interest to scientists working on finfish. It has 15 chapters written by 27 contributors and many of them are highly respected scientists. Given the global importance of salmon, contributors are from many countries including 11 from Japan and Russia. These authors bring slightly different and important perspectives to the book, and their expertise and research may not be known to many young scientists in Europe and in the Americas. The volume starts with an overview of salmon, their economic and social importance, and their impacts on the environment. Subsequent topics include morphological, physiological and behavioural differences between wild and farmed salmon; growth, food utilisation and water flow requirements of wild and hatchery salmon; the real and potential ecological impacts of sea cages and hatcheries; the potential use of waste product (gelatine) from the salmon industry; salmon behaviour and genetics including their broad applications that contribute to our understanding of fish biology, and nutritional and anti-nutritional factors in salmon culture. There are also chapters on environmental impacts and the economic importance of the commercial fishery and salmon farming industry; these are very important components of the industry, especially to the seafood sector.

Available in PDF, EPUB and Kindle. Book excerpt: "This book addresses the current need for a holistic approach in comparative and evolutionary biology and offers numerous applications of the modern methods of phylogenetic systematics and historical ecology, using the North American fish fauna as its case study. This major synthesis, the first published work of its kind, provides a theoretical and methodological foundation for future studies in ichthyology, evolutionary biology, and other fields of comparative biology." "Several introductory pieces present major statements of general principles, detailed examinations of the diversity and distributions of North American freshwater fishes, and what is known of their systematic relationships. The rest of the volume's 30 papers then contribute new phylogenetic hypotheses for a significant number of taxa. Along the way, the reader is introduced to the principles, first, of phylogenetic systematics - the reconstruction of evolutionary or ancestor-descendant relationships of groups of organisms on the basis of heritable traits - and, second, of historical ecology - a comprehensive research program that links systematics with many areas of comparative biology. Together, the two allow for the formulation of direct and testable hypotheses regarding the evolution of species and their attributes, interspecies interactions, and the formation and persistence of biotic communities. Without these methods that incorporate "historical controls," our estimates of history for all areas of biology are inefficient, indirect, and worst of all, untestable." "This book focuses on North American freshwater fishes not only because the 42 contributors know them so well but also because this highly diverse fauna is well known in so many important aspects (diversity, species distributions, life histories) relevant to evaluating general applications of the new paradigms of systematics and historical ecology. Many other faunas present interesting biotas appropriate for the preparation of a similar piece of work, but no other fauna can claim as complete a knowledge base." "The theme articulated throughout the book underscores the Darwinian proposition of descent with modification. The biological information particular to the North American freshwater fish fauna establishes an invaluable foundation for understanding diversification and advancing education and research. Moreover, the methods, theories, and empirical data presented serve as essential resources for comparative and evolutionary research programs applicable to any biota or taxonomic grouping." "The book includes some 200 illustrations, 60 tables, 10 appendixes, and comprehensive taxonomic and subject indexes."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Available in PDF, EPUB and Kindle. Book excerpt: A cooperative study involving the Department of Fisheries and Oceans Canada, the Alaska Department of Fish and Game, and the Taku River Tlingit First Nation was conducted to estimate the number of spawning Chinook salmon Oncorhynchus tshawytscha in the Taku River in 2003 with a mark-recapture experiment. Fish were captured at Canyon Island on the lower Taku River with fish wheels from May through August and were individually marked with back-sewn, solid-core spaghetti tags. All tagged fish were also batch marked with an opercle punch plus removal of the left axillary appendage. Sampling on the spawning grounds in tributaries was used to estimate the fraction of the population that had been marked. The estimated spawning abundance of small Chinook salmon ( 400 mm long; mid-eye to fork of tail) was 3,489 (SE = 1,052). Spawning abundance of medium-size Chinook salmon (401-659 mm) was estimated to be 16,780 (SE = 2,274). Finally, spawning abundance of large-size fish (= 660 mm) was estimated to be 36,435 (SE = 6,705), and the estimated total of all fish was 56,704 (SE = 7,158). The sum of the peak aerial survey counts of large spawning Chinook salmon conducted at five index tributaries of the Taku River was 16% of the mark-recapture estimate. Age 1.3 fish (1998 brood year) constituted an estimated 40% of the spawning population, followed by age 1.2 fish (1999 brood year), which constituted an estimated 29% of the population
