Fisheries Economics has always been an interdisciplinary field of study with economic analysis based on stock population dynamics, but many published works have focused mainly on theoretical economic issues without much focus on biological details. For the most part, age structured models have been ignored. Bioeconomics of Fisheries Management is a valuable reference text that presents the economic aspects of fisheries management in a broad bioeconomic framework. The book is broken into two parts. Part I covers the traditional areas of fisheries economics, covering topics such as open access, optimal and managed fisheries utilization that is analyzed through a traditional one stock/one fleet model. It also presents the basic results in terms of an age structured model. Part II covers material related to more recent work on bioeconomic models when more rigorous biological components became more prevalent, and views fisheries management with an ecosystems-based approach. Accompanying the book is a user-friendly CD with exercises and examples that aids the reader in applying theoretical principles of population dynamics and fisheries management and regulation. Bioeconomics of Fisheries Management will be a valuable text for researchers, fisheries economists, professionals, and students alike.

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.

Efforts to effectively conserve and manage marine resources are facing increasing complexity of environmental and governance challenges. To address some of these challenges, this book presents advancements in fisheries bioeconomics research that provides significant ideas for addressing emerging environmental and fisheries management issues. Advances in Fisheries Bioeconomics gives insights into innovative approaches dealing with these issues, as well as novel ideas on changes in fisheries management paradigms. With contributions from leading experts in the field, this book offers an examination of a number of topics including: ecosystem based fisheries management; by-catch management and discard bans; the number of players in the fisheries game; the effects of ocean acidification; and the trends and impacts of eco-labeling and eco-certification of fisheries. Through integrating resource biology and ecology with the economics of fishers' behaviour, the authors provide valuable analysis of the current issues in fisheries management. This book will be of interest to those on advanced courses in fisheries science, natural resource biology and ecology, and environmental and natural resource economics. It will also appeal to researchers, policy makers, and advocacy groups around the world.

This book is presented in seven Chapters. Chapter 1 describes the basic assumptions underlying the optimal allocation of natural resources and the inherent characteristics of fisheries that determine, under unrestricted access, the failure to allocate resources, economic inefficiency and overfishing. To mitigate these undesired effects, the bioeconomic literature invokes the allocation of property rights, which in turn must be implemented within a management context. Thus, in this Chapter we suggest some guidelines to conduct management plans. Static and dynamic bioeconomic models are presented in Chapter 2 as a theoretical framework for the design of intelligent management schemes aiming at sustainable use of fish stocks. Classic models are shown, such as the Gordon-Schaefer based on the logistic. We also develop new bioeconomic approaches, such as a distributed-delay model to add realism to Smith's fleet dynamics approach. Chapter 2 also includes an introductory version of a bioeconomic yield-mortality model, and dynamic age-structured models. A comparison of the dynamic and static trajectories is stressed. The price of time and its implications for optimal resource allocation over time is also discussed. For the sake of adding realism to the above models, the systems approach is used in Chapter 3 to model different technological and ecological complexities that occur in marine fisheries. Ecological interdependencies (competition, predation), as well as technological interdependencies resulting from fleets with different fishing power and/or gear types, operating on components of a stock, or on different target species of a "mixed stock", are specified and modelled.

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 coordinate the 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.
