Stock Enhancement and Sea Ranching by Bari Howell,Erlend Moksness,Terje Svasand Pdf

Stock enhancement and sea ranching has been practised for decades for a wide variety of marine fish and invertebrate species in Japan, and for salmonids. As a result, fisheries scientists and managers worldwide have been encouraged to use these techniques to increase the productivity of existing fisheries, to create new fisheries, and to restore those that are no longer viable. Projects are now under way not only in Japan, but on cod in Norway, striped mullet in Hawaii, red drum in Texas, white seabass in California, scallops in New Zealand, shrimp in China and sturgeons in the Caspian Sea, to name a few. This edited work, based on the first International Symposium on Stock Enhancement and Sea Ranching, presents and discusses advances in these techniques and their consequences and sets out to identify the most important priorities for future research.

Restocking and Stock Enhancement of Marine Invertebrate Fisheries by Johann D. Bell,P. C. Rothlisberg,J. L. Munro Pdf

Annotation Many of the world's fisheries are in trouble - they no longer yield the catches, and potential profits, they once did. The habitats that support fisheries have been damaged by pollution and other irresponsible use of coastal land. Destructive fishing methods like trawling and blast fishing have also changed fish habitats resulting in support of fewer fish. The authors draw on more than 1000 scientific papers covering 11 groups/species of marine invertebrates. From this large literature, they distill 20 lessons for assessing and guiding the use of restocking and stock enhancement in the management of invertebrate fisheries. · Written by 7 expert authors · Covers 11 groups/species of marine invertebrates · Reviews over 1000 scientific papers · Identifies 20 lessons that can be learned from past restocking and stock enhancement initiatives · Proposes a new approach to assess the potential value of hatchery releases to complement other forms of management · Assesses progress of disciple against the blueprint for a responsible approach.

Marine Ecology by Muhammet Turkoglu,Umur Önal,Ali İsmen Pdf

During the last decades, aquatic resources have been severely depleted due to human-induced factors such as overexploitation and pollution and more recently due to deviations in the physicochemical parameters of oceans, dramatic changes in weather patterns and melting of glaciers. The effects of these man-made factors are occurring in a relatively shorter time scale and, in many cases, are beyond the capacity of organisms to adapt to these deviations. The majority of natural aquatic resources, which are one of the most important food sources on the planet, are being used to the extent that limits their capacity for regeneration. Despite ongoing attempts towards developing strategies for long-term management of aquatic resources all over the world, efforts have met with limited success. Thus, the sustainable use of aquatic resources has become a very important reality considering a projected human population of 11 billion by the year 2100. With this reality in mind, the purpose of this book is to shed more light on the field of marine ecology by emphasizing the diversity of aquatic life on earth and its importance both as part of a balanced ecosystem and as part of critical source of food on earth. The book covers important findings, discussions and reviews on a variety of subjects on environmental and competitive interactions of marine organisms at different trophic levels and their effects on the productivity, dynamics and structure of marine ecosystems around the world. Each chapter focuses on a specific case in the field of marine ecology and was written by researchers with years of experience in their respective fields. We hope that academicians, researchers and students as well as experts and professionals working in the field of marine ecology will benefit from these contributions. We also hope that this book will inspire more studies to help better understand the marine environment and develop strategies to better protect this crucial element of life on earth.

Ecosystem Concepts for Sustainable Bivalve Mariculture by National Research Council,Division on Earth and Life Studies,Ocean Studies Board,Committee on Best Practices for Shellfish Mariculture and the Effects of Commercial Activities in Drakes Estero, Pt. Reyes National Seashore, California Pdf

U.S. mariculture production of bivalve molluscs-those cultivated in the marine environment-has roughly doubled over the last 25 years. Although mariculture operations may expand the production of seafood without additional exploitation of wild populations, they still depend upon and affect natural ecosystems and ecosystem services. Every additional animal has an incremental effect arising from food extraction and waste excretion. Increasing domestic seafood production in the United States in an environmentally and socially responsible way will likely require the use of policy tools, such as best management practices (BMPs) and performance standards. BMPs represent one approach to protecting against undesirable consequences of mariculture. An alternative approach to voluntary or mandatory BMPs is the establishment of performance standards for mariculture. Variability in environmental conditions makes it difficult to develop BMPs that are sufficiently flexible and adaptable to protect ecosystem integrity across a broad range of locations and conditions. An alternative that measures performance in sustaining key indicators of ecosystem state and function may be more effective. Because BMPs address mariculture methods rather than monitoring actual ecosystem responses, they do not guarantee that detrimental ecosystem impacts will be controlled or that unacceptable impact will be avoided. Ecosystem Concepts for Sustainable Bivalve Mariculture finds that while performance standards can be applied for some broad ecosystem indicators, BMPs may be more appropriate for addressing parameters that change from site to site, such as the species being cultured, different culture methods, and various environmental conditions. This book takes an in-depth look at the environmental, social, and economic issues to present recommendations for sustainable bivalve mariculture.

Marine Fisheries Ecology by Simon Jennings,Michel Kaiser,John D. Reynolds Pdf

This topical and exciting textbook describes fisheries exploitation, biology, conservation and management, and reflects many recent and important changes in fisheries science. These include growing concerns about the environmental impacts of fisheries, the role of ecological interactions in determining population dynamics, and the incorporation of uncertainty and precautionary principles into management advice. The book draws upon examples from tropical, temperate and polar environments, and provides readers with a broad understanding of the biological, economic and social aspects of fisheries ecology and the interplay between them. As well as covering 'classical' fisheries science, the book focuses on contemporary issues such as industrial fishing, poverty and conflict in fishing communities, marine reserves, the effects of fishing on coral reefs and by-catches of mammals, seabirds and reptiles. The book is primarily written for students of fisheries science and marine ecology, but should also appeal to practicing fisheries scientists and those interested in conservation and the impacts of humans on the marine environment. particularly useful are the modelling chapters which explain the difficult maths involved in a user-friendly manner describes fisheries exploitation, conservation and management in tropical, temperate and polar environments broad coverage of 'clasical' fisheries science emphasis on new approaches to fisheries science and the ecosystem effects of fishing examples based on the latest research and drawn from authors' international experience comprehensively referenced throughout extensively illustrated with photographs and line drawings

Public Management and Administration by Ubaldo Comite Pdf

The public sector plays an important role for both regulation and in the delivery of services directly or indirectly. In this context, it is important to consider transformation, change, and innovation, which are the elements on which the main determinants that influence public management and the administration of economic, social, and political systems are based. This book describes the nature of the problem, its multidimensionality, and the need for original approaches, through the contribution of scholars belonging to different disciplines. This book contains nine chapters in a single section (Public Management and Administration), which, through the different approaches to the subject by the authors, help to explain the issues of the public sector.

Aquaculture in China by Jian-Fang Gui,Qisheng Tang,Zhongjie Li,Jiashou Liu,Sena S. De Silva Pdf

Fish have been a major component of our diet and it has been suggested that fish/seafood consumption contributed to the development of the human brain, and this together with the acquisition of bipedalism, perhaps made us what we are. In the modern context global fish consumption is increasing. However, unlike our other staples, until a few years back the greater proportion of our fish supplies were of a hunted origin. This scenario is changing and a greater proportion of fish we consume now is of farmed origin. Aquaculture, the farming of waters, is thought to have originated in China, many millennia ago. Nevertheless, it transformed into a major food sector only since the second half of the last century, and continues to forge ahead, primarily in the developing world. China leads the global aquaculture production in volume, in the number of species that are farmed, and have contributed immensely to transforming the practices from an art to a science. This book attempts to capture some of the key elements and practices that have contributed to the success of Chinese aquaculture. The book entails contributions from over 100 leading experts in China, and provides insights into some aquaculture practices that are little known to the rest of the world. This book will be essential reading for aquaculturists, practitioners, researchers and students, and planners and developers.
