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.

Mangrove ecosystems are being increasingly threatened by human activities. Their biotic productivity supplies food and other resources to the human populations that inhabit or make use of them. This volume highlights the results of a ten-year German / Brazilian research project, called MADAM, in one of the largest continuous mangrove areas of the world, located in northern Brazil. Based on the analysis of the ecosystem dynamics, management strategies for the conservation and sustainable use of mangroves are presented and discussed. Beyond the scientific results, this book also provides guidelines for the development of international cooperation projects.
