Download or read book Marine Fisheries Ecology written by Simon Jennings and published by John Wiley & Sons. This book was released on 2009-04-01 with total page 434 pages. 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

Available in PDF, EPUB and Kindle. Book excerpt: Addressing ecologists, legislators, lawyers, and industrialists alike, Ruth Patrick asks what has been accomplished with the millions of dollars spent on upgrading our surface waters. Has the water improved in spite of the fact that the crayfish, snails, and algae are not those that one would expect to find in natural rivers and estuaries? To evaluate the success of environmental laws over the past two decades, the author examines the aquatic life of river systems in the Delaware Valley, Texas, and Georgia--the only areas in the United States where she found enough biological data to determine trends over time. Although tracing the impact of environmental laws is difficult, Patrick found that for these three water systems the results were generally positive. However, if society as a whole wants effective environmental legislation, organizations must take on a more systematic and orderly approach to data gathering. Patrick argues that in monitoring the waters, one must study protozoa, algae, and worms as well as fish, oysters, and shrimp; one must track amounts of metal as well as low concentrations of oxygen. In proposing options for the future, the author predicts that the cost of such monitoring will be higher than present expenditures, but the cost of lax control will be even greater. Originally published in 1992. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Available in PDF, EPUB and Kindle. Book excerpt: Das zweibändige Werk Fish and Fisheries in Estuaries: A Global Perspective enthält eine Darstellung des aktuellen Wissensstandes über Fische in Ästuaren. In Beiträgen von mehr als fünfzig international anerkannten Forschern und Experten für Ichthyologie in Ästuaren präsentiert dieses wegweisende Übersichtswerk die Themen Fischbestände und funktionelle Gruppen, Rekrutierung und Produktion in Ästuaren, Ernährungsökologie und trophische Dynamik, Erhaltung von Fischen in Ästuaren und viele mehr. In dreizehn ausführlichen Kapiteln werden die wichtigsten Aspekte zu Fischen und Fischerei in Ästuaren rund um die Welt beschrieben. Es wird die Biologie der Fische in Ästuargewässern und ihre Verbindung zu den dortigen Ökosystemen betrachtet, und es wird analysiert, wie sich die menschengemachte Industrialisierung und globale Ereignisse wie der Klimawandel auf einheimische und andere Arten auswirken. Weitere Themen sind die Vielfalt der Lebensräume, das Verhalten von Fischen bei der Nahrungssuche, Instrumente und Modelle der Umwelttechnik, Gefahren und Risiken für Fische und Fischerei in Ästuaren sowie die Gesundheit der Umwelt in Ästuaren. Dieses maßgebliche Referenzwerk enthält detaillierte Informationen über die Biologie und Ökologie von Fischen und Fischerei in Ästuaren und bietet außerdem: * Eine Betrachtung aktueller Ansätze und künftiger Forschungsrichtungen, die darauf abzielen, ein Gleichgewicht zwischen der Nutzung und der Erhaltung von Fischen in Ästuaren zu erreichen * Eine Erörterung der Umweltqualitätsziele sowie der nachhaltigen Fischerei und Bewirtschaftung der Ästuare * Eine Untersuchung, wie sich die zunehmende Nutzung von Ressourcen wie Nahrung, Raum und Wasser durch den Menschen auf die Fischerei in den Ästuaren auswirkt * Zahlreiche internationale Fallstudien zum Fischereimanagement, zu bedrohten Arten, zur Sanierung von Ästuaren, zur Fortpflanzung und Ontogenese und weiteren Themen * Eine Darstellung der Studien- und Probenahmeverfahren, der Feldausrüstung sowie der Verarbeitung, Analyse und Interpretation der Daten Das Werk Fish and Fisheries in Estuaries: A Global Perspective ist ein unverzichtbares Hilfsmittel und eine Referenzquelle für Fischbiologen, Fischereiwissenschaftler, Ökologen und Umweltwissenschaftler, Gewässerökologen, Naturschutzbiologen sowie Studierende der höheren Semester und Dozenten im Bereich Fischbiologie und Fischerei.

Available in PDF, EPUB and Kindle. Book excerpt: Fish recruitment is a key process for maintaining sustainable fish populations. In the marine environment, fish recruitment is carried out in many different ways, all of which have different life history strategies. The objective of this book is to argue for greater linkages between basic and applied research on fisheries recruitment, and assessment and management of exploited fish stocks. Following an introductory chapter, this second edition of Fish Reproductive Biology is organized into 3 main sections: Biology, Population Dynamics and Recruitment Information Critical to Successful Assessment and Management Incorporation of Reproductive Biology and Recruitment Considerations into Management Advice and Strategies The authors collectively bring a wide range of diverse experience in areas of reproductive biology, fisheries oceanography, stock assessment, and management. Fully updated throughout, the book will be of great interest to a wide audience. It is useful as a textbook in graduate and undergraduate courses in fisheries biology, fisheries science, and fisheries resource management and will provide vital information for fish biologists, fisheries scientists and managers.

Available in PDF, EPUB and Kindle. Book excerpt: Stock Identification Methods provides a comprehensive review of the various disciplines used to study the population structure of fishery resources. It represents the worldwide experience and perspectives of experts on each method, assembled through a working group of the International Council for the Exploration of the Sea. The book is organized to foster interdisciplinary analyses and conclusions about stock structure, a crucial topic for fishery science and management. Technological advances have promoted the development of stock identification methods in many directions, resulting in a confusing variety of approaches. Based on central tenets of population biology and management needs, Stock Identification Methods offers a unified framework for understanding stock structure by promoting an understanding of the relative merits and sensitivities of each approach.* Describes eighteen distinct approaches to stock identification grouped into sections on life history traits, environmental signals, genetic analyses, and applied marks* Features experts' reviews of benchmark case studies, general protocols, and the strengths and weaknesses of each identification method* Reviews statistical techniques for exploring stock patterns, testing for differences among putative stocks, stock discrimination, and stock composition analysis* Focuses on the challenges of interpreting data and managing mixed-stock fisheries
