Available in PDF, EPUB and Kindle. Book excerpt: Stock Identification Methods, 2e, continues to provide a comprehensive review of the various disciplines used to study the population structure of fishery resources. It represents the worldwide experience and perspectives of experts on each method, assembled through a working group of the International Council for the Exploration of the Sea. The book is organized to foster interdisciplinary analyses and conclusions about stock structure, a crucial topic for fishery science and management. Technological advances have promoted the development of stock identification methods in many directions, resulting in a confusing variety of approaches. Based on central tenets of population biology and management needs, this valuable resource offers a unified framework for understanding stock structure by promoting an understanding of the relative merits and sensitivities of each approach. Describes 18 distinct approaches to stock identification grouped into sections on life history traits, environmental signals, genetic analyses, and applied marks Features experts' reviews of benchmark case studies, general protocols, and the strengths and weaknesses of each identification method Reviews statistical techniques for exploring stock patterns, testing for differences among putative stocks, stock discrimination, and stock composition analysis Focuses on the challenges of interpreting data and managing mixed-stock fisheries

Download or read book Improving Fish Stock Assessments written by National Research Council and published by National Academies Press. This book was released on 1998-02-27 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ocean harvests have plateaued worldwide and many important commercial stocks have been depleted. This has caused great concern among scientists, fishery managers, the fishing community, and the public. This book evaluates the major models used for estimating the size and structure of marine fish populations (stock assessments) and changes in populations over time. It demonstrates how problems that may occur in fisheries dataâ€"for example underreporting or changes in the likelihood that fish can be caught with a given type of gearâ€"can seriously degrade the quality of stock assessments. The volume makes recommendations for means to improve stock assessments and their use in fishery management.

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.

Available in PDF, EPUB and Kindle. Book excerpt: "The identification of discrete resource units, whether they be called stocks, populations, migratory groups or management units, is critical to the effective management of our aquatic resources. Advances in techniques and equipment have been made in recent years in the area of such identifications. A workshop to review these advances was organized by the Panama City Laboratory of the Southeast Fisheries Center, National Marine Fisheries Service. It was held at the Miracle Mile Complex, Panama City Beach, Florida, Nov. 4-6, 1985. The major objective of the Stock Identification Workshop was to gain a more comprehensive understanding of stock identification problems and approaches to their solutions. The workshop was designed to give an opportunity to the participants to share information on methods of stock identification and to review their application to aquatic resources. The program format consisted of three sections--" Preface, paragraphs 1-2.

Download or read book Quantitative Fisheries Stock Assessment written by R. Hilborn and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book really began in 1980 with our first microcomputer, an Apple II +. The great value of the Apple II + was that we could take the computer programs we had been building on mainframe and mini-computers, and make them available to the many fisheries biologists who also had Apple II + 's. About 6 months after we got our first Apple, John Glaister came through Vancouver and saw what we were doing and realized that his agency (New South Wales State Fisheries) had the same equipment and could run the same programs. John organized a training course in Australia where we showed about 25 Australian fisheries biologists how to use microcomputers to do many standard fisheries analyses. In the process of organizing this and sub sequent courses we developed a series of lecture notes. Over the last 10 years these notes have evolved into the chapters of this book.

Download or read book Fish Identification Tools for Biodiversity and Fisheries Assessments written by Johanne Fischer and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2013 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: This review provides an appraisal of existing, state-of-the-art fish identification (ID) tools (including some in the initial stages of their development) and shows their potential for providing the right solution in different real-life situations. The ID tools reviewed are: Use of scientific experts (taxonomists) and folk local experts, taxonomic reference collections, image recognition systems, field guides based on dichotomous keys; interactive electronic keys (e.g. IPOFIS), morphometrics (e.g. IPez), scale and otolith morphology, genetic methods (Single nucleotide polymorphisms [SNPs] and Barcode [BOL]) and Hydroacoustics. The review is based on the results and recommendations of the workshop "Fish Identification Tools for Fishery Biodiversity and Fisheries Assessments," convened by FAO FishFinder and the University of Vigo and held in Vigo, Spain, from 11 to 13 October 2011. It is expected that it will help fisheries managers, environmental administrators and other end users to select the best available species identification tools for their purposes.--

Download or read book Blood Types in Pacific Salmon written by George J. Ridgway and published by . This book was released on 1960 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intraspecific differences in erythrocyte antigens (blood types) were shown to occur in four species of Pacific salmon, the sockeye or red salmon (Oncorhynchus nerka), the chinook or king salmon (O. tshawytscha), the chum salmon (O. keta), and the pink salmon (O. gorbuscha). Antisalmon-erythrocyte sera prepared in rabbits and chickens were used after absorption of species-specific antibodies. Some of these blood types were shown to differ in their frequency of occurrence between different geographic races. In addition, isoimmunizations were prepared and at least eight different patterns of antigenic composition were displayed by the cells tested. These results indicate that considerable antigenic diversity exists in salmon. Reagents to detect valuable markers for the investigation of geographic races of salmon should be obtained through further research.
