Download or read book Fisheries Acoustics written by John Simmonds and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Living resources of the sea and fresh water have long been an important source of food and economic activity. With fish stocks continuing to be over-exploited, there is a clear focus on fisheries management, to which acoustic methods can and do make an important contribution. The second edition of this widely used book covers the many technological developments which have occurred since the first edition; highly sophisticated sonar and computer processing equipment offer great new opportunities and Fisheries Acoustic, 2e provides the reader with a better understanding of how to interpret acoustic observations and put them to practical use. Well known and respected authors Emphasis on practical acoustic methods Detailed coverage of a commercially and environmentally important subject A vital tool for fisheries scientists, fisheries oceanographers, environmental biologists, ecologists, population biologists, fish biologists, and marine biologists. All those involved with design and use of acoustic equipment. Libraries in research establishments, government stations and universities where fisheries science is studied or taught will find this a welcome addition to their shelves.

Book Synopsis Fisheries Acoustics by : K. A. Johannesson
Download or read book Fisheries Acoustics written by K. A. Johannesson and published by Bernan Press(PA). This book was released on 1983 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: The manual begins with a presentation of key physical principles used in fisheries acoustics and continues with a general description of the necessary equipment and its functions. An explanation is given of the acoustic equations followed by the acoustic properties of fish when occurring singly or in schools. Acoustic survey concepts are discussed prior to a description of calibration methods used to determine the electronic and acoustic parameters of the equipment. Use of the equipment in a systematic manner at sea leads on to the sources of error that can arise and explains how these may be removed or minimised. Finally methods are given for the collection and presentation of data in various forms, together with different ways in which to improve results by the use of statistics.

Available in PDF, EPUB and Kindle. Book excerpt: Until now, there has not been any work that systematically presents the subject of acoustic fish reconnaissance, details all major aspects of applying acoustic equipment in commercial fish reconnaissance, and offers sufficient analysis of the effectiveness of fish-finding techniques. Acoustic Fish Reconnaissance responds to this need by providing t

Download or read book Inland Fisheries written by and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current high demand for fish and increased awareness of the role of the environment in supporting human well being has led to a situation where attitudes to inland water resources are changing rapidly. Trends in resource use and environmental impact are very evident in inland waters which are particularly vulnerable as they act as collectors of all the activities occurring in their basins and rank as some of the most endangered ecosystems in the world. The principle changes influencing the evolution of the aquatic resource for fisheries are described in this book, which has been compiled for the Food and Agriculture Organization of the United Nations.

Available in PDF, EPUB and Kindle. Book excerpt: free from any of the overtones that often constrain professional fisheries meetings. The present volume is the result. This volume aims to be useful as an appraisal of the state of the art by a mixed collection of insiders and outsiders. Most interestingly, I think, it aims (especially in the four group reports) to identify some of the major areas of unresolved controversy and some of the major questions yet unanswered. I see the book as essentially a tentative statement - often by several dissonant voices - about directions in which we may be heading; the book is emphatically not a canonical utterance on how to do things. It is intended to stimulate, not to codify. Following the usual Dahlem Workshop format, the discussions were organized under four themes. Although crisp demarcation is not possible, the first two themes broadly deal with biological aspects of the dynamics of single populations and the dynamics of systems with many species. The later two themes take up questions of management under uncertainty and multispecies management. In all this, the word "fish" is interpreted broadly to include such taxonomically varied beasts as whales, shrimp, crabs, shellfish, and squid, along with fish in a strictly zoological sense.
