Opis

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.

Recenzje

"This very useful guide is now in its second considerably improved and updated edition highly recommended." ( Work Boat World, October 2008)

"The new volume of Fisheries Acoustics captures the advances in the technology associated with the use of acoustics to find, classify, size, enumerate, examine the behaviour of, and help manage various types of fish."(Reviews in Fisheries Science, November 2006)

"A thorough treatment of the acoustic instruments, sophisticated displays, and microprocessor–based signal processing used throughout the world to map the distribution of fish, estimate biomass, locate fish shoals, monitor fish movement, and study fish behavior. Emphasizes the practical methods for assessing fish stock; also discusses the design, execution, and interpretation of surveys, drawing from examples in many parts of the world."(Book News (SciTech Book News), September 2005)

"If you really want to know how depth sounders, sonars and their ilk work, you need this book. If you want to learn how to use your fish finding equipment more effectively, you need it even more."(Ausmarine)

"This textbook is an essential reference for professionals involved with the design and use of acoustic equipment for assessing fisheries and plankton populations...this book will be an invaluable tool for any practitioner or researcher requiring an understanding of the fundamentals of fisheries acoustics.the modernised edition is timely and welcome"(Reviews in Fish Biology and Fisheries (2007), 17:633–634)
