Zustand: Hervorragend. Zustand: Hervorragend | Sprache: Englisch | Produktart: Bücher | This book reviews the gray system and combines its latest research results in fishery science. The chapters cover the basic concept and theory of gray system, original data processing and gray sequence generation, gray correlation analysis, gray cluster analysis, gray system modeling, gray prediction, gray decision-making, and gray linear programming. The theory of gray system is a new cross-sectional discipline founded in 1982 by Professor Deng Julong, a well-known scholar in China. In recent decades, it has not only been deepened and expanded in theory but also widely used in the fields of society, economy, ocean, agriculture, fishery, and other fields, and made a series of significant scientific achievements. These have laid the foundation for the important position of the gray system theory.Due to the great uncertainty of the fishery resources and the fishery environment involved in the fishery science system, which is completely different from the natural resources onthe land, the data and information belong to the category of ¿poor information¿, and the variability and uncertainty are greater than other natural resources. As an extremely effective analytical method and tool, gray system theory has been applied increasingly in fishery science. The book is developed based on well-read and practical literature and will help scientists and research units engaged in scientific research and teaching in fishery science and related fields to develop new research methods and tools.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book systematically introduces the knowledge system and research results of fisheries forecasting. Itis divided into four parts and seven chapters. The first part is the introduction, which mainly introduces the basic concepts, the nature of the subject, and the research contents, as well as the current status of research. The second part is about the basic knowledge of fisheries forecasting, including overview of the world marine environment, fishshoalingand migration distribution, the relationship between fish behavior and marine environment, and the basic theory of forming fishing ground. The third part is the focus of this book, including the basic principles and methods offisheriesforecasting, as well as the application of new techniques and methods infisheriesforecasting. The fourth part is the comprehensive application of fisheries forecasting, including the general situation of world marine fisheries, the impact of global marineenvironment changes on fisheries resources andfishing ground, and case studying of fisheriesforecasting of important economic species, such as oceanic squid, jack mackerel, anchovy, and skipjack.The study of this book will help everyone to master the basic principles and methods of fisheries forecasting, as well as the application of new technologies and methods in important economic species, and lay a foundation for future work in the field of marine fisheries.

Buch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Fisheries resources are an important component of natural resources. It is an important source of high-quality animal protein and food for humans, which provides employment, economic benefits and social welfare for people engaged in fishing activities. It also has played an important role in food safety, economic development, and foreign trade.Fisheries resources economics is an important branch of both applied economics and resource economics. Its research object is fishery resources and its economic problems. The economics of fishery resources is to focus on the relationship between the demand for human economic activities and the supply of fishery resources, as well as between fishery resources and its development. This book expounds the reasons for the economic problems of fishery resources and the theoretical principles for solving them, so as to reveal the objective rules of the allocation of fishery resources in different regions and at different times, to coordinatethe relationship between the utilization of fishery resources and economic development, and to realize the sustainable development of fishery economy. This book will also provide learning materials for undergraduates, graduate students and practitioners engaged in fishery resources development and scientific management.
