Download or read book Hakes written by Hugo Arancibia and published by John Wiley & Sons. This book was released on 2015-12-21 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The species of hake, making up the genus Merluccius, are commercially important and currently largely over exploited, with many stocks badly depleted and showing only limited signs of recovery. From the end of the 1990s, concepts such as sustainability, ecosystem-based approaches to fisheries management, a code for the responsible conduct for fisheries, governance and others have emerged or have been considered by politicians, stakeholders and society. Moreover, new tools for stock assessment have been developed. But many hake stocks of the genus Merluccius show no sign of restoration. Hakes: Biology and Exploitation brings together a wealth of important information on the biology and exploitation of hake and hoki stocks around the world. Each chapter provides an overview of the fisheries of each species in an ecological and environmental context, looking at stock distribution, characteristics of the environment, life history, reproduction, diet, growth, mortality, pricing and markets of each geographical region and the hake species found there. With chapters written by regional experts on hake species and included within Wiley-Blackwell’s prestigious Fish and Aquatic Resources Series, Hakes: Biology and Exploitation provides up-to-date and comparative information, including new approaches to fisheries management, for all those involved in fisheries management, aquatic ecology and biological sciences.

Download or read book Marine Conservation written by G. Carleton Ray and published by John Wiley & Sons. This book was released on 2013-10-11 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Providing a guide for marine conservation practice, Marine Conservation takes a whole-systems approach, covering major advances in marine ecosystem understanding. Its premise is that conservation must be informed by the natural histories of organisms together with the hierarchy of scale-related linkages and ecosystem processes. The authors introduce a broad range of overlapping issues and the conservation mechanisms that have been devised to achieve marine conservation goals. The book provides students and conservation practitioners with a framework for thoughtful, critical thinking in order to incite innovation in the 21st century. "Marine Conservation presents a scholarly but eminently readable case for the necessity of a systems approach to conserving the oceans, combining superb introductions to the science, law and policy frameworks with carefully chosen case studies. This superb volume is a must for anyone interested in marine conservation, from students and practitioners to lay readers and policy-makers." —Simon Levin, George M. Moffett Professor of Biology, Department of Ecology & Evolutionary Biology, Princeton University
Download or read book Birds written by Heimo Mikkola and published by BoD – Books on Demand. This book was released on 2021-07-21 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many humans, birds are the most fascinating group of animals and they are definitely among the best-known and studied organisms. Thanks to global citizen science data, we know that there are some 50 billion individual birds in the world at present, which is about six birds for every human on the planet. Birds have an important role as indicators of the state of the environment, giving them high public value. Human-related global impacts such as climate changes and accelerating urbanization force extant species to continuous adaptations, population modifications, or even outright extinction. This book includes nine chapters covering such topics as bird genetics, the colour of avian plumage, conservation problems, sustainable hunting, habitat disturbance, range expansion and introductions, and long-term bird population changes and challenges. A key chapter explains the genetic rules and reasons why we have continuously more bird species in the world and why we may end up having 7,000 species more than the present 11,000 species.

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 Namibia s Fisheries written by Ussif Rashid Sumaila and published by Eburon Uitgeverij B.V.. This book was released on 2004 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: As we search urgently for a strategy of sustainable natural resource management, an international debate is brewing over destructive modern fishery methods. Namibia's Fisheries is a timely contribution to this discussion as it examines Namibia's Benguela upwelling system, an area that supports traditional and modern forms of fishery. This volume analyzes the Namibian experience in fishery management, featuring essays by researchers, Namibian fishery managers, and international specialists that cover a range of ecological and social issues. Namibia's Fisheries will be a valuable resource for researchers, conservationists, and students of fishery management.

Download or read book The Ecosystem Approach to Fisheries written by Gabriella Bianchi and published by CABI. This book was released on 2008 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Sustainable use of aquatic ecosystems is high on regional, national and international agendas and central to the implementation of international agreements on biological diversity, responsible fisheries and fish stock management. Since 2001, when political commitments were made to implement the ecosystem approach, countries have begun to incorporate ecosystem considerations into their fisheries management and have met with varied success." "The Ecosystem Approach to Fisheries covers both theoretical andapplied aspects of sustainable management, with a particular emphasis on reviewing concepts and addressing implementation issues in the form of case studies from around the world. Personal experiences are considered from diverse backgrounds and discuss the constraints encountered, strategies identified and best practices to facilitate further implementation."--BOOK JACKET.
