Download or read book The Future of Fisheries Science in North America written by Richard J. Beamish and published by Springer Science & Business Media. This book was released on 2009-02-07 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Research Required to Understand the Impact of Tactical Mid frequency Sonar Transmission on Fish Fisheries and Fisheries Habitat written by and published by . This book was released on 2007 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: As reported in NPS-OC-07-004, analysis of public comments responding to the Draft Environmental Impact Statement (October 2005) for the proposed Undersea Warfare Training Range (USWTR) in Onslow Bay off North Carolina identified three main areas of public concern. One of these concerns, the effects on fish and fisheries habitats of mid-frequency active (MFA) sonar, further identified four sub-areas of concern: catch rates, spawning choruses, distribution and migratory behavior, and physiological effects. A workshop was held in April 2007 at Duke University to address these sub-areas of concern. The purpose of the workshop was to outline a program of research that could help determine how MFA sonar might affect fish and fisheries resources. This report summarizes the recommendations that emerged from that workshop. Specifically, a long-term research and development plan is articulated, as well as the priorities within that plan.

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.

Download or read book Fisheries Sonar written by R. B. Mitson and published by Wiley-Blackwell. This book was released on 1991-01-08 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with all aspects of modern echo-sounding and sonar as used by those concerned with the exploitation and management of fisheries. From the basic physics, through the operation of the systems, the practical aspects are well illustrated with many diagrams and photographs, including a large section on paper recordings and colour sounder displays of fish traces. The applications described range from a small portable echo-sounder for freshwater fishing in shallow waters to the Deep Tow echo-sounder used at 2500m depth. it includes some remarkable accoustic images of underwater scenes and the latest methods for tracking fish.
Download or read book Sonar Systems written by Nikolai Kolev and published by BoD – Books on Demand. This book was released on 2011-09-12 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is an edited collection of research articles covering the current state of sonar systems, the signal processing methods and their applications prepared by experts in the field.

Special section in the book is dedicated to sonar signal processing methods covering: passive sonar array beamforming, direction of arrival estimation, signal detection and classification using DEMON and LOFAR principles, adaptive matched field signal processing. The image processing techniques include: image denoising, detection and classification of artificial mine like objects and application of hidden Markov model and artificial neural networks for signal classification. The biology applications include the analysis of biosonar capabilities and underwater sound influence on human hearing. The marine science applications include fish species target strength modeling, identification and discrimination from bottom scattering and pelagic biomass neural network estimation methods. Marine geology has place in the book with geomorphological parameters estimation from side scan sonar images.

Download or read book Computers in Fisheries Research written by Bernard A. Megrey and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1989 we were asked by Dr Vidar Wespestad (National Oceanographic and Atmospheric Administration. National Marine Fisheries Service. Alaska Fisheries Science Center. Seattle. USA) to prepare and convene a session at the 1992 World Fisheries Congress in Athens. Greece on computer appli cations in fisheries. We agreed that the idea was a good one and the computer session turned out to be very successful. The computer session was organized in three parts: training classes. informal demonstrations accompanied by posters. and oral presentations of scientific papers. We were both amazed by the high level of interest and the high quality of contributions presented at the paper session. Returning from the World Fisheries Congress. we suggested to the International Council for the Exploration of the Sea (ICES) in Copenhagen to hold a theme session on the topic 'Computers in Fisheries Research' at their statutory meeting the fol lowing year in Dublin. Ireland. The proposal was very positively received by ICES and we began organizing this new meeting with Dr John Ramster of the Ministry of Agriculture. Fisheries and Food. Fisheries Laboratory. Lowestoft. England. Based on our experience with the World Fisheries Congress. we expected a maximum of 15 titles would be submitted to the ICES theme session. Accordingly. the ICES symposium was originally allo cated one half-day time slot. The response we received from the call for papers. however. exceeded our most optimistic expectations. A total of 62 abstracts were submitted. Consequently.
