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.

This book addresses issues related to sources of groundwater pollution such as arsenic, uranium, fluoride and their effects on human health. It discusses extensively the removal of heavy metals, arsenic and fluoride from drinking water. Bioremediation and phyto remediation on biomass productivity are treated in several chapters in the book. The volume highlights leachate characteristics analysed both in the laboratory and in field studies assessing the trace metals in rainwater. This book is a study on the judicious management of natural resources and exposes environmental problems particularly those related to pollution and bioremediation.

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.
