Download or read book Freshwater Fisheries Ecology written by John F. Craig and published by John Wiley & Sons. This book was released on 2016-01-12 with total page 920 pages. 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 Biology of Sharks and Their Relatives Second Edition written by Jeffrey C. Carrier and published by CRC Press. This book was released on 2012-04-09 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: Virtually every area of research associated with sharks and their relatives has been strongly impacted by the revolutionary growth in technology. The questions we can now ask are very different than those reported even two decades ago. Modern immunological and genetic techniques, satellite telemetry and archival tagging, modern phylogenetic analysis, GIS, and bomb dating, are just a few of the techniques and procedures that have become a part of our investigative lexicon. A modern synthesis of the biology of Chondrichthyans, Biology of Sharks and Their Relatives, Second Edition discusses significant advances in the development and application of new molecular techniques to the understanding of the phylogenetic relationships among and between these groups. The book considers the effect of global changes on the status of sharks and their relatives, and how advances in technology and analytical techniques have changed not only how we approach problem solving and scientific investigations, but how we formulate questions. The book also introduces applications of new and novel laboratory devices, techniques, and field instruments. This second edition of the award winning and groundbreaking original exploration of the fundamental elements of the taxonomy, systematics, physiology, and ecology of sharks, skates, rays, and chimera, presents cohesive and integrated coverage of key topics and discusses technological advances used in modern shark research. Offering a well-rounded picture for students and researchers, and far above competitors in scope and research, this new volume holds a wealth of data on the current status of Chondrichthyan research and provides the basis and springboard for original research.

Download or read book In the Light of Evolution written by National Academy of Sciences and published by National Academies Press. This book was released on 2009-11-30 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two Centuries of Darwin is the outgrowth of an Arthur M. Sackler Colloquium, sponsored by the National Academy of Sciences on January 16-17, 2009. In the chapters of this book, leading evolutionary biologists and science historians reflect on and commemorate the Darwinian Revolution. They canvass modern research approaches and current scientific thought on each of the three main categories of selection (natural, artificial, and sexual) that Darwin addressed during his career. Although Darwin's legacy is associated primarily with the illumination of natural selection in The Origin, he also contemplated and wrote extensively about what we now term artificial selection and sexual selection. In a concluding section of this book, several science historians comment on Darwin's seminal contributions. Two Centuries of Darwin is the third book of the In the Light of Evolution series. Each installment in the series explores evolutionary perspectives on a particular biological topic that is scientifically intriguing but also has special relevance to contemporary societal issues or challenges. The ILE series aims to interpret phenomena in various areas of biology through the lens of evolution and address some of the most intellectually engaging, as well as pragmatically important societal issues of our times.

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.”

Available in PDF, EPUB and Kindle. Book excerpt: Through case studies, opposing viewpoints, and primary documents, this reference work examines the environmental and sustainability issues regarding water as well as how water is an intrinsic part of human culture. Every culture and ecosystem on earth depends on water. As the world's climate changes, human culture is increasingly threatened by the seemingly opposite problems of having too little clean, potable water and "having too much water"—e.g., flooding, melting polar ice caps, and rising sea levels. What are the solutions that humanity must collectively pursue to protect our ability to flourish on planet earth? Water Planet: The Culture, Politics, Economics, and Sustainability of Water on Earth offers an unprecedented examination of the critical subject of water sustainability. Its essays, viewpoints, case studies, and documents show how this vital resource that many in first-world countries take for granted is intricately woven into not only basic human survival but also cultural, political, and economic stability. Readers will learn about topics such as flooding and drought; the growing problem of water pollution; the connections between water and gender, including gender equity and gender aspects of water ownership; the effects of global temperature changes on the water supply; concerns regarding fishing and overfishing; water security; and sustainable water management.

Download or read book Salmonid Fishes written by Yuri P. Altukhov and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important title encompasses features of genetic processes in complexly organised population systems of salmonids, one of the most commercially valuable families of fish worldwide. Translated from the original work in Russian, the authors have taken the opportunity to update and revise the work, much of it appearing in the English language for the first time. Covering such important concepts as optimal gene diversity and the unfavourable influence of fishery and hatchery reproduction on the genetic structure of salmon populations, the authors have drawn together a huge wealth of information that will form the cornerstone of much new work in the future. The authors of Salmonid Fishes have between them many years of research experience and practical knowledge in the area and the English translation of this important work, which has been edited by Professor John Thorpe and Professor Gary Carvalho, provides vital information for all those involved in salmonid management, exploitation and conservation, including fish biologists, fisheries managers, conservation and population biologists, ecologists and geneticists.

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.
