Genre: Science

Fish Conservation offers, for the first time in a single volume, a readable reference with a global approach to marine and freshwater fish diversity and fishery resource issues. Gene Helfman brings together available knowledge on the decline and restoration of freshwater and marine fishes, providing ecologically sound answers to biodiversity declines as well as to fishery management problems at the subsistence, recreational, and commercial levels. Written in an engaging and accessible style, the book: considers the value of preserving aquatic biodiversity offers an overview of imperiled fishes on a taxonomic and geographic basis presents a synthesis of common characteristics of imperiled fishes and their habitats details anthropogenic causes of decline examines human exploitation issues addresses ethical questions surrounding exploitation of fishes The final chapter integrates topics and evaluates prospects for arresting declines, emphasizing the application of evolutionary and ecological principles in light of projected trends. Throughout, Helfman provides examples, explores case studies, and synthesizes available information from a broad taxonomic, habitat, and geographic range. Fish Conservation summarizes the current state of knowledge about the degradation and restoration of diversity among fishes and the productivity of fishery resources, pointing out areas where progress has been made and where more needs to be done. Solutions focus on the application of ecological knowledge to solving practical problems, recognizing that effective biodiversity conservation depends on meeting human needs through management that focuses on long term sustainability and an ecosystem perspective.

The second edition of The Diversity of Fishes represents a major revision of the world’s most widely adopted ichthyology textbook. Expanded and updated, the second edition is illustrated throughout with striking color photographs depicting the spectacular evolutionary adaptations of the most ecologically and taxonomically diverse vertebrate group. The text incorporates the latest advances in the biology of fishes, covering taxonomy, anatomy, physiology, biogeography, ecology, and behavior. A new chapter on genetics and molecular ecology of fishes has been added, and conservation is emphasized throughout. Hundreds of new and redrawn illustrations augment readable text, and every chapter has been revised to reflect the discoveries and greater understanding achieved during the past decade. Written by a team of internationally-recognized authorities, the first edition of The Diversity of Fishes was received with enthusiasm and praise, and incorporated into ichthyology and fish biology classes around the globe, at both undergraduate and postgraduate levels. The second edition is a substantial update of an already classic reference and text.

Ecology and Conservation of Fishes

Author: Harold M. Tyus
Publisher: CRC Press
ISBN: 9781439858547
Release Date: 2011-10-19
Genre: Nature

Written as a stand-alone textbook for students and a useful reference for professionals in government and private agencies, academic institutions, and consultants, Ecology and Conservation of Fishes provides broad, comprehensive, and systematic coverage of all aquatic systems from the mountains to the oceans. The book begins with overview discussions on the ecology, evolution, and diversity of fishes. It moves on to address freshwater, estuarine, and marine ecosystems and identifies factors that affect the distribution and abundance of fishes. It then examines the adaptations of fishes as a response to constraints posed in ecosystems. The book concludes with four chapters on applied ecology to discuss the critical issues of management, conservation, biodiversity crises, and climate change. Major marine fisheries have collapsed, and there are worldwide declines in freshwater fish populations. Fishery scientists and managers must become more effective at understanding and dealing with resource issues. If not, fish species, communities, and entire ecosystems will continue to decline as habitats change and species are lost. Ecology and Conservation of Fishes has taken a historical and functional approach to explain how we got where we are, providing old and new with a better foundation as ecologists and conservationists, and most importantly, it awakens senses of purpose and need. Past management practices are reviewed, present programs considered, and the need for incorporating principles of applied ecology in future practices is emphasized.

Marine Conservation

Author: P. Keith Probert
Publisher: Cambridge University Press
ISBN: 9780521326858
Release Date: 2017-06-30
Genre: Nature

Providing a comprehensive account of marine conservation, this book examines human use and abuse of the world's seas and oceans and their marine life, and the various approaches to management and conservation. Healthy marine ecosystems - the goods and services that they provide - are of vital importance to human wellbeing. There is a pressing need for a global synthesis of marine conservation issues and approaches. This book covers conservation issues pertinent to major groups of marine organisms, such as sharks, marine turtles, seabirds and marine mammals; key habitats, from estuaries, wetlands and coral reefs to the deep sea; and from local and regional to international initiatives in marine conservation. An ideal resource for students, researchers and conservation professionals, the book pays appropriate attention to the underlying marine biology and oceanography and how human activities impact marine ecosystems, enabling the reader to fully understand the context of conservation action and its rationale.

Vier Fische

Author: Paul Greenberg
Publisher: ebook Berlin Verlag
ISBN: 9783827074744
Release Date: 2011-03-05
Genre: Nature

Der preisgekrönte Autor und passionierte Angler Paul Greenberg nimmt uns mit auf eine Reise über die Flüsse und Meere dieser Welt und erzählt die Geschichte jener vier Fischarten, die mittlerweile überall die Speisekarten beherrschen: Lachs, Barsch, Kabeljau und Thunfisch. Er besucht norwegische Großfarmen, die jährlich 500 000 Tonnen Lachs produzieren - mit Hilfe genetischer Techniken, die ursprünglich bei der Schafzucht zum Einsatz kamen. In Alaska besichtigt er die einzige Fair-Trade-Fischerei der Welt. Er erklärt, warum die Meerestiere zunehmend mit Quecksilber und anderen Schadstoffen belastet sind, und schildert, wie der Mittelmeerbarsch zu einer global nachgefragten Ware werden konnte. Greenberg stellt viele der Fragen, die immer mehr Menschen beim Anblick einer Speisekarte oder der Tiefkühltruhe unseres Supermarkts beschäftigen: Was ist der Unterschied zwischen Wild-, Zucht- und Biofisch? Welchen Fisch können wir bedenkenlos essen? Was bedeutet Überfischung eigentlich? Lassen sich Fische wirklich domestizieren wie andere Tiere auch, oder sollten wir generell aufhören, Fisch zu essen? Fische, so Greenbergs Fazit, sind unser letztes wirklich ?wildes Nahrungsmittel. Womöglich nicht mehr lange. Nur wenn wir besser verstehen, unter welchen Bedingungen und um welchen Preis Fisch auf unseren Tellern landet, werden wir dem Lebensraum - und der Nahrungsquelle - Meer mit neuer, dringend gebotener Achtung begegnen.
