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.

Fisheries science in North America is changing in response to a changing climate, new technologies, an ecosystem approach to management and new thinking about the processes affecting stock and recruitment. Authors of the 34 chapters review the science in their particular fields and use their experience to develop informed opinions about the future. Everyone associated with fish, fisheries and fisheries management will find material that will stimulate their thinking about the future. Readers will be impressed with the potential for new discoveries, but disturbed by how much needs to be done in fisheries science if we are to sustain North American fisheries in our changing climate. Officials that manage or fund fisheries science will appreciate the urgency for the new information needed for the stewardship of fish populations and their ecosystems. Research organizations may want to keep some extra copies for a future look back into the thoughts of a wide range of fisheries professionals. Fisheries science has been full of surprises with some of the surprises having major economic impacts. It is important to minimize these impacts as the demand for seafood increases and the complexities of fisheries management increase.

In this edited work, international experts in fisheries management and ecology review and appraise the status of river fisheries, assessment methodology, constraints on development, issues and options regarding management and associated problems in both temperate and tropical countries. Recommendations are made to improve management and an attempt is made to provide guidelines for formulating policy, for planning methodology and for evaluating future activities. Assessment of fish community structure and dynamics. Factors constraining stock recruitment. Fish habitat requirements. Instream flow needs. Impact of water resource schemes. Rehabilitation of river fisheries. Enhancement of fish stocks. Exploitation of stocks. Management of migratory fish stocks. Conservation of endangered species. Integrated river management. Bioeconomic issues. Legislation. Multinational management of rivers. Case studies.

This publication of the NOAA Professional Paper NMFS Series is the product of a special symposium on "Emerging Technologies for Reef Fisheries Research and Management" held during the 56th annual Gulf and Caribbean Fisheries Institute meeting in Tortola, British Virgin Islands, November 2003. The purpose of this collection is to highlight the diversity of questions and issues in reef fisheries management that are benefiting from applications of technology. Topics cover a wide variety of questions and issues from the study of individual behavior, distribution and abundance of groups and populations, and associations between habitats and fish and shellfish species.
