Available in PDF, EPUB and Kindle. Book excerpt: Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.

Download or read book Salmon written by Jude Isabella and published by Rocky Mountain Books Ltd. This book was released on 2014-11-14 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salmon: A Scientific Memoir investigates a narrative that is important to the identity of the Pacific Northwest Coast – the salmon as an iconic species. Traditionally it’s been a narrative that is overwhelmingly about conflict. But is that always necessarily the case? The story follows John Steinbeck’s advice: the best way to achieve reality is to combine narrative with scientific data. By following ecologists, archaeologists and fisheries biologists studying salmon, humans and their shared habitat, the reader learns about the fish through the eyes of scientists in the field. Each chapter focuses on a portion of the salmon’s journey to and from their natal streams; on one of the five Pacific salmon species most commercially important to North Americans; and on the different ways scientists study the fish. It’s also about the scientific journey of ecologists, archaeologists and fisheries biologists and how the labs gathering data today echo coastal indigenous people who have harvested salmon successfully since the end of the last ice age. Each group established a reciprocal economic system, one that revolves around community and knowledge, a system with straightforward rules, sometimes as simple as “you get what you give.”

Download or read book Nature and Bureaucracy written by David Jenkins and published by Taylor & Francis. This book was released on 2022-09-08 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book questions how bureaucracies conceive of, and consequently interact with, nature, and suggests that our managed public landscapes are neither entirely managed nor entirely wild, and offers several warnings about bureaucracies and bureaucratic mentality. One prominent challenge facing scientists, policymakers, environmental activists, and environmentally concerned citizens, is to recognize that human influence in the natural world is pervasive and has a long history. How we act, or choose not to act, today will continue to determine the future of the natural world. Western-style management of nature, mediated by economic rationality and state bureaucracies, may not be the best strategy to maintain environmental integrity. The question is, what kinds of human influence, conceived of in the widest possible sense, will produce ideal environments for future generations? The related question is, who gets to choose? The author approaches the problem of analyzing the mutual influence of human and natural systems from two perspectives: as an objective scholar investigating bureaucracies and natural systems from the outside, and over the last decade as an inside practitioner working in various roles in federal land management agencies developing policies and regulations involved in the control of natural systems. This book will be of great interest to students and scholars of natural resource management, policy and politics, and professionals working in environmental management roles as well as policymakers involved in public policy and administration.

Download or read book Pacific Salmon Life Histories written by Cornelis Groot and published by UBC Press. This book was released on 1991 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pacific salmon are an important biological and economic resource of countries of the North Pacific rim. They are also a unique group of fish possessing unusually complex life histories. There are seven species of Pacific salmon, five occurring on both the North American and Asian continents (sockeye, pink, chum, chinook, and coho) and two (masu and amago) only in Asia. The life cycle of the Pacific salmon begins in the autumn when the adult female deposits eggs that are fertilized in gravel beds in rivers or lakes. The young emerge from the gravel the following spring and will either migrate immediately to salt water or spend one or more years in a river or lake before migrating. Migrations in the ocean are extensive during the feeding and growing phase, covering thousands of kilometres. After one or more years the maturing adults find their way back to their home river, returning to their ancestral breeding grounds to spawn. They die after spawning and the eggs in the gravel signify a new cycle. Upon this theme Pacific salmon have developed many variations, both between as well as within species. Pacific Salmon Life Histories provides detailed descriptions of the different life phases through which each of the seven species passes. Each chapter is written by a scientist who has spent years studying and observing a particular species of salmon. Some of the topics covered are geographic distribution, transplants, freshwater life, ocean life, development, growth, feeding, diet, migration, and spawning behaviour. The text is richly supplemented by numerous maps, illustrations, colour plates, and tables and there is a detailed general index, as well as a useful geographical index.

Download or read book Physiological Ecology of Pacific Salmon written by Cornelis Groot and published by UBC Press. This book was released on 2010-10-01 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every year, countless juvenile Pacific salmon leave streams and rivers on their migration to feeding grounds in the North Pacific Ocean and the Bering Sea. After periods ranging from a few months to several years, adult salmon enter rivers along the coasts of Asia and North America to spawn and complete their life cycle. Within this general outline, various life history patterns, both among and within species, involve diverse ways of exploiting freshwater, estuarine, and marine habitats. There are seven species of Pacific salmon. Five (coho, chinook chum, pink, and sockeye) occur in both North America and Asia. Their complex life histories and spectacular migrations have long fascinated biologists and amateurs alike. Physiological Ecology of Pacific Salmon provides comprehensive reviews by leading researchers of the physiological adaptations that allow Pacific Salmon to sustain themselves in the diverse environments in which they live. It begins with an analysis of energy expenditure and continues with reviews of locomotion, growth, feeding, and nutrition. Subsequent chapters deal with osmotic adjustments enabling the passage between fresh and salt water, nitrogen excretion and regulation of acid-base balance, circulation and gas transfer, and finally, responses to stress. This thorough and authoritative volume will be a valuable reference for students and researchers of biology and fisheries science as they seek to understand the environmental requirements for the perpetuation of these unique and valuable species.

Download or read book Travels Among the Dena written by Frederica de Laguna and published by University of Washington Press. This book was released on 2011-10-01 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: This robust and engaging travel narrative re-creates a remarkable adventure in the summer of 1935, when Frederica de Laguna, then in her late 20s, led a party of three other scientists down the rivers of the middle and lower Yukon valley, making a geological and archaeological reconnaissance. De Laguna has based her story on her field notes, journals, and letters home. She augments this first-hand account with excerpts from the reports of earlier explorers and data published after her trip. The result is a fascinating and informative cross-cut of historical events along the Yukon River and its tributaries. Travels Among the Dena chronicles the expedition from its outfitting in Seattle and the trip by steamer and railway to Fairbanks and Nenana, through an 80-day journey on skiffs down the Tanana and Yukon rivers to Holy Cross near the coast, with side trips on the Koyukuk, Khotol, and Innoko rivers, before a one-day return flight to Fairbanks with pioneer bush pilot Noel Wien. Maps illustrate the route taken downriver, and the author’s photographs capture images of the time. The resulting volume is both a delightful addition to the literature of travel adventure in Alaska and an important contribution to the discipline of anthropology.

Download or read book Genetics of Subpolar Fish and Invertebrates written by Anthony J. Gharrett and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fisheries genetics researchers will find invaluable the thirty-eight peer-reviewed contributions in this book, presented at the 20th Lowell Wakefield Fisheries Symposium "Genetics of Subpolar Fish and Invertebrates," held in May 2002 in Juneau, Alaska. Looming over concerns of lost fisheries stocks and persistent erosion of genetic variability are predictions of global warming, which may further tax genetic resources. One consequence is an increased reliance on genetic applications to many aspects of fisheries management, aquaculture, and conservation. The contributions in this book are important to modern fisheries science and genetics, and illustrate the evolution of the field over the past decade. The improved technology provides tools to address increasingly complicated problems in traditional applications and ecological and behavioral studies. The union between molecular and quantitative genetics, where many of the major questions about population structure and evolution remain unanswered, will also benefit from the new technologies.

Download or read book Freshwater Fish Distribution written by Tim M. Berra and published by University of Chicago Press. This book was released on 2008-09-15 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
