Book Synopsis Manual on Estimation of Selectivity for Gillnet and Longline Gears in Abundance Surveys by : Holger Hovgêrd
Download or read book Manual on Estimation of Selectivity for Gillnet and Longline Gears in Abundance Surveys written by Holger Hovgêrd and published by Food & Agriculture Org.. This book was released on 2008-04-29 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual defines methods for estimating selectivity of gillnet and longline gears, with particular reference to the use of these gears in abundance surveys. The manual illustrates how gear design, the basic concepts of size selection and fish morphometric data can be used to model selectivity. Statistical estimation methods are described in detail, and examples given of their application in spreadsheets. The efficient use of these gears in abundance and research surveys is also discussed. Although the manual concentrates on gillnets and longlines, the methods given are general enough to be relevant to any research involving gear selectivity
Book Synopsis The Montenegrin Adriatic Coast by : Aleksandar Joksimović
Download or read book The Montenegrin Adriatic Coast written by Aleksandar Joksimović and published by Springer Nature. This book was released on 2021-06-23 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first of two volumes that together provide an integrated picture of the Montenegrin Adriatic coast, presenting the natural components of the system as well as the chemical composition and chemical processes in the extended area. This book describes the biology and ecology of the high seas of the Montenegrin coast, with a special focus on their biodiversity, flora and fauna, fisheries, mariculture, marine reptiles and mammals. The data has been collected through national and international projects over the last few decades and provides the reader with models and recommendations for the protection of this vital region of the Adriatic coast, as well as scientific recommendations for the sustainable use of its biological resources. Given the breadth and depth of its coverage, the book offers an invaluable source of information for researchers, students and environmental managers alike.
Book Synopsis Handbook of Fish Biology and Fisheries by : Paul J. B. Hart
Download or read book Handbook of Fish Biology and Fisheries written by Paul J. B. Hart and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent decades have witnessed strong declines in fish stocks around the globe, amid growing concerns about the impact of fisheries on marine and freshwater biodiversity. Fisheries biologists and managers are therefore increasingly asking about aspects of ecology, behaviour, evolution and biodiversity that were traditionally studied by people working in very separate fields. This has highlighted the need to work more closely together, in order to help ensure future success both in management and conservation. The Handbook of Fish Biology and Fisheries has been written by an international team of scientists and practitioners, to provide an overview of the biology of freshwater and marine fish species together with the science that supports fisheries management and conservation. This volume, subtitled Fisheries, focuses on a wide range of topics, including the history of fisheries science, methods of capture, marketing, economics, major models used in stock assessments and forecasting, ecosystem impacts, marine protected areas and conservation. It builds on material in Volume 1, Fish Biology, which ranges from phylogenetics and biogeography to physiology, recruitment, life histories, genetics, foraging, reproductive behaviour and community ecology. Together, these books present the state of the art in our understanding of fish biology and fisheries and will serve as valuable references for undergraduates and graduates looking for a comprehensive source on a wide variety of topics in fisheries science. They will also be useful to researchers who need up-to-date reviews of topics that impinge on their fields, and decision makers who need to appreciate the scientific background for management and conservation of aquatic ecosystems. To order volume II, go to the box in the top right hand corner. Alternatively to order volume I, go to: http://www.blackwellpublishing.com/book.asp?ref=0632054123 or to order the 2 volume set, go to: http://www.blackwellpublishing.com/book.asp?ref=0632064838. Provides a unique overview of the study of fish biology and ecology, and the assessment and management of fish populations and ecosystems. The first volume concentrates on aspects of fish biology and ecology, both at the individual and population levels, whilst the second volume addresses the assessment and management of fish populations and ecosystems. Written by an international team of expert scientists and practitioners. An invaluable reference tool for both students, researchers and practitioners working in the fields of fish biology and fisheries.
Book Synopsis Fisheries Management in Areas Beyond National Jurisdiction by : Daniela Diz Pereira Pinto
Download or read book Fisheries Management in Areas Beyond National Jurisdiction written by Daniela Diz Pereira Pinto and published by Martinus Nijhoff Publishers. This book was released on 2012-10-01 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book analyses the law-making of ecosystem-based fisheries management in marine areas beyond national jurisdiction as a post-development of the United Nations Convention on the Law of the Sea (UNCLOS) so as to avoid stocks collapse and destruction of critical habitats, and increase the resilience of marine ecosystems.

Book excerpt: Fish accomplish most of their basic behaviors by swimming. Swimming is fundamental in a vast majority of fish species for avoiding predation, feeding, finding food, mating, migrating and finding optimal physical environments. Fish exhibit a wide variety of swimming patterns and behaviors. This treatise looks at fish swimming from the behavioral and

Available in PDF, EPUB and Kindle. Book excerpt: In the sixteen years since the last edition of Von Brant’s classic work was published, fishing and fisheries have undergone vast changes. Not only has there been great progress in the development of new tools, materials and techniques, but the industry has seen an increasing need to address controversial issues such as declining fish stocks, enormous quantities of bycatch and discard and the impact of towed fishing gear on the environment. Fully revised and updated to reflect such changes, the fourth edition of this widely read and popular book offers: A unique, comprehensive survey of the evolution of fishing methods throughout the world Approximately 750 illustrations showing the extensive range of methods, techniques and equipment used in fishing across the globe Fishing gear classified according to the FAO system Additional chapters: Fishing Effects on Fish Stocks and Environment and Fishery and Gear Research All researchers, fisheries scientists, fisheries students, administrators and libraries in universities and research establishments where fish and fisheries are studied and taught will find this book a valuable addition to their shelves.

Book Synopsis Methodology Manual : Measurement of Fishing Gear Selectivity by : Dickson, W
Download or read book Methodology Manual : Measurement of Fishing Gear Selectivity written by Dickson, W and published by Fisheries and Oceans. This book was released on 1995-01-01 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fishing selectivity can be defined as the ability to target and capture fish by species, size, or sex (or a combination of these) during harvesting operations, allowing all incidental by-catch to be released unharmed. This manual outlines the steps and processes necessary to monitor selectivity demonstrations, collect data on selectivity, and validate scientific research on selectivity under normal fishing operations. Some mathematical and statistical examples are shown to clarify the methodologies and to facilitate understanding and application. The manual is intended to provide assistance to technicians and senior fishing crew in the planning, execution, and reporting of size and species trials and demonstrations with mobile and fixed gears. Sections of the manual cover measurement of selectivity, experiment design, experimental methods, data analysis, and the reporting of results. Case studies of experiments using both fixed and mobile gear are included.
