Book Synopsis Improving Fish Stock Assessments by : National Research Council
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.
Book Synopsis On the Dynamics of Exploited Fish Populations by : Raymond J.H. Beverton
Download or read book On the Dynamics of Exploited Fish Populations written by Raymond J.H. Beverton and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the fishes, a remarkably wide range of biological adaptations to diverse habitats has evolved. As well as living in the conventional habitats of lakes, ponds, rivers, rock pools and the open sea, fish have solved the problems of life in deserts, in the deep sea, in the cold antarctic, and in warm waters of high alkalinity or of low oxygen. Along with these adaptations, we find the most impressive specializations of morphology, physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins, sailfish and warm-blooded tunas, air-breathing in catfish and lungfish, parental care in the mouth-brooding cichlids, and viviparity in many sharks and toothcarps. Moreover, fish are of considerable importance to the survival of the human species in the form of nutritious, delicious and diverse food. Rational exploitation and management of our global stocks of fishes must rely upon a detailed and precise insight of their biology. The Chapman & Hall Fish and Fisheries Series aims to present timely volumes reviewing important aspects of fish biology. Most volumes will be of interest to research workers in biology, zoology, ecology and physiology but an additional aim is for the books to be accessible to a wide spectrum of non-specialist readers ranging from undergraduates and postgraduates to those with an interest in industrial and commercial aspects of fish and fisheries.
Book Synopsis Sustaining Marine Fisheries by : National Research Council
Download or read book Sustaining Marine Fisheries written by National Research Council and published by National Academies Press. This book was released on 1999-03-19 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluctuations and declines in marine fish populations have caused growing concern among marine scientists, fisheries managers, commercial and recreational fishers, and the public. Sustaining Marine Fisheries explores the nature of marine ecosystems and the complex interacting factors that shape their productivity. The book documents the condition of marine fisheries today, highlighting species and geographic areas that are under particular stress. Challenges to achieving sustainability are discussed, and shortcomings of existing fisheries management and regulation are examined. The volume calls for fisheries management to adopt a broader ecosystem perspective that encompasses all relevant environmental and human influences. Sustaining Marine Fisheries offers new approaches to building workable fisheries management institutions, improving scientific data, and developing management tools. The book recommends ways to change current practices that encourage overexploitation of fish resources. It will be of special interest to marine policymakers and ecologists, fisheries regulators and managers, fisheries scientists and marine ecologists, fishers, and concerned individuals.
Book Synopsis Ecosystem-Based Fisheries Management by : Jason Link
Download or read book Ecosystem-Based Fisheries Management written by Jason Link and published by Cambridge University Press. This book was released on 2010-10-07 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Responsible fisheries management is of increasing interest to the scientific community, resource managers, policy makers, stakeholders and the general public. Focusing solely on managing one species of fish stock at a time has become less of a viable option in addressing the problem. Incorporating more holistic considerations into fisheries management by addressing the trade-offs among the range of issues involved, such as ecological principles, legal mandates and the interests of stakeholders, will hopefully challenge and shift the perception that doing ecosystem-based fisheries management is unfeasible. Demonstrating that EBFM is in fact feasible will have widespread impact, both in US and international waters. Using case studies, underlying philosophies and analytical approaches, this book brings together a range of interdisciplinary topics surrounding EBFM and considers these simultaneously, with an aim to provide tools for successful implementation and to further the debate on EBFM, ultimately hoping to foster enhanced living marine resource management.
Book Synopsis The Maximum (Un)Sustainable Yield. An Assessment by : Sophia Milusheva

Available in PDF, EPUB and Kindle. Book excerpt: Essay from the year 2020 in the subject Politics - Environmental Policy, grade: 19/20, Sciences Po., Paris, course: Ocean governance and marine policy, language: English, abstract: This paper aims to investigate the roots of MSY and what prevents it from being as sustainable as intended. There exist three models of MSY; by Raymond and Hold, by Ricker, and by Schaefer. This paper focuses on Schaefer’s Surplus Production Model, explaining how it works in regard to stock assessment and calculation approaches. Next, the scientific limitations of MSY are discussed, followed by the main focus of this paper, namely taking a closer look at the history of MSY in order to explain current critiques. It is found out that MSY is in fact a policy disguised as science which complicates the execution of its good intentions, and that fishery policies were not based on how successful MSY theories were, but rather the success of the theories was based on the fishery policies. These historic evolutions largely explain why the Maximum Sustainable Yield cannot be truly sustainable. Finally, several recommendations for the improvement of MSY and fisheries management are suggested. The term “over-fishing” was already present in the 1850s, however the extent of marine fisheries resources overexploitation was only realized in the 1900s. Simple and easily understandable guidelines on catch limits became desirable in fisheries management and thus a fixed maximum catch that a population could support seemed like an excellent reference point. The Maximum Sustainable Yield (MSY) has a hundred years long history, emerging from mathematical models that were first introduced to population ecology in the 1930s. It further developed and bloomed in the 1950s, as Surplus Production Models were developed. Today, MSY is applied internationally by almost all regional management bodies, and is therefore widely used for the assessment of exploited stocks worldwide. However, there is a widespread criticism regarding its effectiveness.

Book Synopsis Food Webs and Biodiversity by : Axel G. Rossberg
Download or read book Food Webs and Biodiversity written by Axel G. Rossberg and published by John Wiley & Sons. This book was released on 2013-06-03 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food webs have now been addressed in empirical and theoretical research for more than 50 years. Yet, even elementary foundational issues are still hotly debated. One difficulty is that a multitude of processes need to be taken into account to understand the patterns found empirically in the structure of food webs and communities. Food Webs and Biodiversity develops a fresh, comprehensive perspective on food webs. Mechanistic explanations for several known macroecological patterns are derived from a few fundamental concepts, which are quantitatively linked to field-observables. An argument is developed that food webs will often be the key to understanding patterns of biodiversity at community level. Key Features: Predicts generic characteristics of ecological communities in invasion-extirpation equilibrium. Generalizes the theory of competition to food webs with arbitrary topologies. Presents a new, testable quantitative theory for the mechanisms determining species richness in food webs, and other new results. Written by an internationally respected expert in the field. With global warming and other pressures on ecosystems rising, understanding and protecting biodiversity is a cause of international concern. This highly topical book will be of interest to a wide ranging audience, including not only graduate students and practitioners in community and conservation ecology but also the complex-systems research community as well as mathematicians and physicists interested in the theory of networks. "This is a comprehensive work outlining a large array of very novel and potentially game-changing ideas in food web ecology." —Ken Haste Andersen, Technical University of Denmark "I believe that this will be a landmark book in community ecology ... it presents a well-established and consistent mathematical theory of food-webs. It is testable in many ways and the author finds remarkable agreements between predictions and reality." —Géza Meszéna, Eötvös University, Budapest

Download or read book The Ecosystem Approach to Fisheries written by Gabriella Bianchi and published by CABI. This book was released on 2008 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Sustainable use of aquatic ecosystems is high on regional, national and international agendas and central to the implementation of international agreements on biological diversity, responsible fisheries and fish stock management. Since 2001, when political commitments were made to implement the ecosystem approach, countries have begun to incorporate ecosystem considerations into their fisheries management and have met with varied success." "The Ecosystem Approach to Fisheries covers both theoretical andapplied aspects of sustainable management, with a particular emphasis on reviewing concepts and addressing implementation issues in the form of case studies from around the world. Personal experiences are considered from diverse backgrounds and discuss the constraints encountered, strategies identified and best practices to facilitate further implementation."--BOOK JACKET.
Book Synopsis Fisheries Bioeconomics by : J.C. Seijo
Download or read book Fisheries Bioeconomics written by J.C. Seijo and published by Daya Books. This book was released on 2001 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overutilization of fish stocks, the overcapitalization of fisheries, the removal of associated benefits to society and growing concern over the conservation of marine biodiversity have resulted in a line of fisheries research that is multidisciplinary, dynamic and precautionary in approach. All the biological, ecological and economic factors need to be analysed if the forces regulating the dynamics of a fishery are to be appraised. This publication looks at the assumptions underlying the optimal allocation of renewable natural resources; lists the bioeconomic points of reference resulting from analysis of fisheries is supposed conditions of equilibrium; analysis bioeconomic models according to ecological interdependence factors (such as competition and predation) and technological factors (such as competition between fleets with different fishing capacity); offers a time-series analysis of fisheries and estimates the level of optimal effort; proposes mathematical models applied to bioeconomic analysis to support fisheries management plans; refutes the assumption of uniform resource distribution, incorporating a spatial dimension in fisheries dynamics analysis; and expounds basic elements of decision-making theory and criteria that reflect different attitudes to risk aversion in fisheries management.

Download or read book Ocean Recovery written by Ray Hilborn and published by Oxford University Press, USA. This book was released on 2019-06-27 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last two decades, the scientific and popular media have been bombarded by gloom and doom stories of the future of fisheries, the status of fish stocks, and the impact of fishing on marine ecosystems. Dozens of certification and labeling schemes have emerged to advise consumers on what seafood is sustainable. In recent years, an opposing narrative has emerged emphasizing the success of fisheries management in many places, the increasing abundance of fish stocks in those places, and the prescription for sustainable fisheries. However, there has been no comprehensive survey of what really constitutes sustainability in fisheries, fish stock status, success and failures of management, and consideration of the impacts of fishing on marine ecosystems. This book will explore very different perspectives on sustainability, and bring together the data from a large number of studies to show where fish stocks are increasing, where they are declining, the consequences of alternative fisheries management regimes, and what is known about a range of fisheries issues such as the impacts of trawling on marine ecosystems. Ocean Recovery is aimed principally at a general audience that is already interested in fisheries but seeks both a deeper understanding of what is known about specific issues and an impartial presentation of all the data rather than selected examples used to justify a particular perspective or agenda. It will also appeal to the scientific community eager to know more about marine fisheries and fishing data, and serve as the basis for graduate seminars on the sustainability of natural resources.

Book Synopsis Sustainable Fishery Systems by : Anthony Charles
Download or read book Sustainable Fishery Systems written by Anthony Charles and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive attempt to adopt an 'integrated' interdisciplinary approach to the study of fisheries. Fisheries are discussed as holistic 'systems', with emphasis on their structure, operation and dynamics. The book's interdisciplinary approach is applied to an analysis of problems faced in pursuing 'sustainable fisheries', with emphasis on six dominant themes: sustainability, uncertainty, complexity, conflict, fishing rights and the nature of management. Within this discussion, several major directions in current fishery thinking are explored, notably the precautionary approach, the ecosystem approach, co-management, and robust management for resilient fisheries.
