Available in PDF, EPUB and Kindle. Book excerpt: This topical and exciting textbook describes fisheries exploitation, biology, conservation and management, and reflects many recent and important changes in fisheries science. These include growing concerns about the environmental impacts of fisheries, the role of ecological interactions in determining population dynamics, and the incorporation of uncertainty and precautionary principles into management advice. The book draws upon examples from tropical, temperate and polar environments, and provides readers with a broad understanding of the biological, economic and social aspects of fisheries ecology and the interplay between them. As well as covering 'classical' fisheries science, the book focuses on contemporary issues such as industrial fishing, poverty and conflict in fishing communities, marine reserves, the effects of fishing on coral reefs and by-catches of mammals, seabirds and reptiles. The book is primarily written for students of fisheries science and marine ecology, but should also appeal to practicing fisheries scientists and those interested in conservation and the impacts of humans on the marine environment. particularly useful are the modelling chapters which explain the difficult maths involved in a user-friendly manner describes fisheries exploitation, conservation and management in tropical, temperate and polar environments broad coverage of 'clasical' fisheries science emphasis on new approaches to fisheries science and the ecosystem effects of fishing examples based on the latest research and drawn from authors' international experience comprehensively referenced throughout extensively illustrated with photographs and line drawings

Download or read book Ecosystem Based Fisheries Management written by Jason Link and published by Cambridge University Press. This book was released on 2010-10-07 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Responsible fisheries management is of increasing interest to the scientific community, resource managers, policy makers, stakeholders and the general public. Focusing solely on managing one species of fish stock at a time has become less of a viable option in addressing the problem. Incorporating more holistic considerations into fisheries management by addressing the trade-offs among the range of issues involved, such as ecological principles, legal mandates and the interests of stakeholders, will hopefully challenge and shift the perception that doing ecosystem-based fisheries management is unfeasible. Demonstrating that EBFM is in fact feasible will have widespread impact, both in US and international waters. Using case studies, underlying philosophies and analytical approaches, this book brings together a range of interdisciplinary topics surrounding EBFM and considers these simultaneously, with an aim to provide tools for successful implementation and to further the debate on EBFM, ultimately hoping to foster enhanced living marine resource management.

Download or read book Fisheries Biology Assessment and Management written by Michael King and published by John Wiley & Sons. This book was released on 2013-04-16 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: This excellent second edition of Fisheries Biology, Assessment and Management, has been fully updated and expanded, providing a book which is an essential purchase for students and scientists studying, working or researching in fisheries and aquatic sciences. In the same way that excessive hunting on land has threatened terrestrial species, excessive fishing in the sea has reduced stocks of marine species to dangerously low levels. In addition, the ecosystems that support coastal marine species are threatened by habitat destruction, development and pollution. Open access policies and subsidised fishing are placing seafood in danger of becoming a scarce and very expensive commodity for which there is an insatiable demand. Positive trends include actions being taken to decrease the incidental catches of non-target species, consumer preferences for seafood from sustainable fisheries, and the establishment of no-take areas that provide refuges for marine species. But there is an urgent need to do more. Because there is an increasing recognition of the need to manage ecosystems as well as fish stocks, this second edition of this bestselling text book includes an additional chapter on marine ecology. Chapters on parameter estimation and stock assessment now include step-by-step instructions on building computer spreadsheet models, including simulations with random variations that realistically emulate the vagaries of nature. Sections on ecosystem management, co-management, community-based management and marine protected areas have been expanded to match the increased interest in these areas. Containing many worked examples, computer programs and numerous high quality illustrations, Fisheries Biology, Assessment and Management, second edition, is a comprehensive and essential text for students worldwide studying fisheries, fish biology, aquatic and biological sciences. As well as serving as a core text for students, the book is a superb reference for fisheries and aquatic researchers, scientists and managers across the globe, in both temperate and tropical regions. Libraries in all universities where fish biology, fisheries, aquatic sciences and biological sciences are studied and taught will need copies of this most useful new edition on their shelves.

Download or read book Biodiversity of Freshwater Ecosystems written by Suhaib A. Bandh and published by CRC Press. This book was released on 2022-12-22 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new volume examines the ecological importance, threats, protection, and management of the biodiversity of freshwater ecosystems, such as lakes, ponds, rivers, streams, reservoirs, pools, and wetlands. As populations have been increasing exponentially, humans are using freshwater ecosystems severely, resulting in habitat destruction and breakdown. Environmental contamination, climate change, the introduction of harmful and invasive organisms, unplanned dredging and de-weeding processes, disposal of sewer systems in freshwater bodies, and badly planned water diversions are the leading causes of habitat loss in freshwaters. These impacts have led to significant decreases in the numbers and productivity of many freshwater species and decreased biodiversity in freshwater. This book presents a selection of primary research and review papers on several freshwater aquatic biodiversity studies, which involve evaluating plants, macroinvertebrates, macrophytes, benthic zones, and fish diversity in freshwater ecosystems. It provides an abundance of new information on freshwater biodiversity distribution, status, and patterns. Key features: Discusses the importance, threats, and management of biodiversity of freshwater ecosystems Provides detailed coverage of modern and updated techniques used in the evaluation and conservation of freshwater biodiversity Looks at the impact of pesticides pollution on freshwater environs, and on aquatic and terrestrial life Reviews how global climate change affects freshwater biodiversity Biodiversity of Freshwater Ecosystems: Threats, Protection, and Management promotes the enhancement and strengthening of freshwater protection and its unique biodiversity for scientists, policymakers, scholars, researchers, NGOs, and the public, providing necessary background knowledge and practical tools to help manage aquatic ecosystems and their biodiversity in a holistic manner.
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 Ecosystems of the Deep Oceans written by P.A. Tyler and published by Elsevier. This book was released on 2003-03-27 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume examines the deep sea ecosystem from a variety of perspectives. The initial chapters examine the deep-sea floor, the deep pelagic environment and the more specialised chemosynthetic environments of hydrothermal vents and cold seeps. These environments are examined from the perspective of the relationship of deep-sea animals to their physico-chemical environment.Later chapters examine the biogeography of the main deep oceans (Atlantic, Pacific and Indian) with particular attention to the downward flux of surface-derived organic matter and how this drives the processes within the deep-sea ecosystem. The peripheral deep seas including the polar seas and the marginal deep seas (inter alia the Mediterranean, Red, Caribbean and Okhotsk seas) are explored in the same context. The final chapters examine the processes occurring in the deep sea and include an analysis of why the deep sea has high species diversity, how the fauna respond to organic input and how species have adapted reproductive activity in the deep sea. The volume concludes with an analysis of the anthropogenic impact on the deep sea.

Download or read book The State of World Highly Migratory Straddling and Other High Seas Fishery Resources and Associated Species written by Jean-Jacques Maguire and published by Food & Agriculture Org.. This book was released on 2006 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fisheries for highly migratory species are important in all oceans and semi-enclosed seas, except for polar regions. Fisheries for straddling fish stocks are much more localised, primarily occurring in a few regions where continental shelves extend beyond the 200 miles Exclusive Economic Zone (EEZ), while most fisheries for other high seas fishery resources are deep-water fisheries. This publication examines issues relating to the stocks of these resources, including information on their state of exploitation. Findings include that about 30 percent of the stocks of highly migratory tuna and tuna-like species, more than half of highly migratory oceanic sharks and nearly two-thirds of the straddling stocks and the stocks of other high seas fishery resources are overexploited or depleted. Although the stocks concerned represent only a small fraction of the world fishery resources, they are key indicators of the state of an overwhelming part of the ocean ecosystem which appears to be more overexploited than EEZs.
