Lake Taihu, China : Dynamics and Environmental Change
There are many shallow lakes in the world. Many of them play an important socio-economic role as contributors to the drinking water supply, in flood attenuation, fisheries and recreation activities. Because of the current anthropogenic changes in the environment, such lakes rapidly respond to eutrophication and swamping. It is often hard to address these issues because many changes in the ecosystems of shallow lakes are associated with little studied physical processes. This interaction between the aquatic biota and the physical and chemical environment increases the complexity of shallow lake ecosystems. Lake Taihu, located in the delta of Yangtze River, is a typical large, shallow eutrophic lake with area of 2338 km2 and maximum depth of less than 3m . This book provides basic data on various aspects of this lake and summarizes research work on the interaction between its ecology and physical limnology. It will be a reference for teachers and students of freshwater ecology and biology, the aquatic environment in general, and, most strikingly, for all those interested in physical limnology.
Issues of Decapod Crustacean Biology
This volume presents the proceedings of the eighth Colloquium Crustacea Decapoda Mediterranea, which was held at the Ionian University on Corfu Island, Greece, from 2 to 6 September 2002, and reflects recent advancements in decapod crustacean research. The meeting is the oldest European carcinological event, organized regularly at 3-year intervals since 1972. Although focused on the Mediterranean Sea, worldwide contributions provided a forum for fruitful contact and scientific exchange. The book covers up-to-date issues in decapod crustacean research, including genetics, morphology, reproduction, ecology, behaviour and fisheries, and it is primarily aimed at scientists interested in decapod crustacean research, but other scientists and decision-makers working on marine ecology and fisheries will also find up-to-date information on relevant issues.
By-catch Reduction in the Worlds Fisheries
This book comes after several decades of outstanding and successful research that has helped ameliorate some of the most important and controversial fisheries issues in the world – those associated with the unwanted wastage of fish from by-catch and discarding. The 8 chapters encompass contributions from 27 of the world’s leading experts in by-catch reduction. They take the reader through most aspects of the field at a variety of scales and viewpoints. They examine the methodologies used to develop by-catch reduction techniques and provide new avenues for assisting and broadening such work. Case studies are provided that encompass most of the world’s fishing techniques and regions.
Bill Ricker : An appreciation
This book is the first complete biography of one of the founders of fishery science, William Edwin (Bill) Ricker (1908 - 2001). Bill is immortalized in the Ricker Curve. He developed the Curve in his studies of stock and recruitment in fisheries, but it has been widely applied in many areas of science. Bill is best known for his contributions to fishery science, but he was also internationally recognized as an entomologist and a scientific editor. This book combines Bill’s own recollections with contributions from those who knew him and worked with him as a colleague during his multifaceted career. In an article written shortly before his death, Bill gives his own account of his career and intellectual development.
A Sea Change: The Exclusive Economic Zone and Governance Institutions for Living Marine Resources
A Sea Change in a Changing Sea The oceans, seas and coastal areas encompass over 70% of the earth’s surface. They are a critical driver of the earth’s hydrologic cycle and climate system, important for c- merce, transport, and tourism, a source of economically important living marine resources, minerals such as hydrocarbons, as well as new pharmaceutical compounds. The marine environment provides essential habitats for thousands of marine living 1 2 resources, which in turn contribute significantly to global food security, employment, 3 and trade. Overall, the sea’s contribution to human welfare, in terms of market and non-market resources and environmental services, has been estimated at US$21 trillion/year (Costanza, 2000). However, despite the importance of the ocean realm to humans, there is a growing sense that human impacts are destabilizing this system. Some experts believe that current fishing levels are approaching or exceeding the total 4 productivity of the ocean ecosystem (National Research Council, 1999).
Making Fisheries Management Work : Implementation of Policies for Sustainable Fishing
This book seeks to widen the perspective taken on implementation in fisheries management. The cases presented in this volume addresses legal, administrative, and political challenges regarding implementation of resource conservation policies. The book addresses problems relating to goal achievement, but also causes of deliberate change of political goals during implementation. Fisheries management systems are embedded in inert social structures and natural conditions that vary among different states. Consequently, the book takes a historical and comparative approach, describing the historical developments of national implementation systems and the conditions that shaped their development. It thus seeks to explain why national fisheries management systems have evolved differently, focusing on Norwegian, Faeroese, and EU/Danish management systems. The descriptive and explanatory outlines are accompanied by qualitative assessments of the systems effectiveness as tools for collective action.
Lake Victoria : Ecology, Resources, Environment
Recently, there has been, and continues to be, a tremendous interest on Lake Victoria and its environs, both locally and internationally. A casual browsing on the Internet indicates that the entries on the Lake have been rising phenomenally. At the same time, the issues discussed are as diverse as they are varied in their treatment of the subject, both in terms of depth and comprehensiveness. The information on Lake Victoria and its environ is scattered, isolated, and sometimes confusing even though documentation on the subject are available. Despite this situation, the fact remains that various people (e. g. , secondary and universitystudents,researchers,practitioners,etc. ,)wouldliketoaccess and know more about the Lake and its environs. Aware of the existing information gap about this world’s second largest fresh water Lake, this book is intended to provide readers with up-to-date information pertaining the Lake. The book gives an in-depth coverage of environmental issues, - source endowment, poverty amidst plenty, development opportunities, challenges and other related issues facing the Lake and its environs. It aims at providing information on the above variables, which hopefully will address the needs of various users.
Bioeconomic modelling and valuation of exploited marine ecosystems
This book offers an environmental-economic analysis of exploited ecosystems with a clear policy orientation. The study tries to move beyond traditional economic fishery analysis in two respects. First, several theoretical and numerical models are offered that combine economic and ecological descriptions of fisheries. These models give special attention to spatial processes as well as to combining exploitation and conservation objectives. Second, valuation and stakeholder concerns are addressed in empirical analyses employing both qualitative and quantitative approaches. The latter is done by using advanced methods of monetary valuation. In addition, the first part of the book presents short, introductory overviews of integrated assessment, economic modeling of fishery management, and incorporating uncertainty in fisheries analysis.
Aspects of Illegal, Unreported and Unregulated Fishing in the Southern Ocean
Overfishing threatens the viability of high seas living resources. Furthermore, controls to prevent overfishing are inadequate. Illegal, Unreported and Unregulated (IUU) fishing is a product of overfishing and affects all marine fisheries. Southern Ocean fisheries have been particularly targeted by IUU fishing. The efforts of the Convention for the Conservation of Antarctic Marine Living Resources Commission and the Australian government to adopt complementary measures to deter IUU fishing in the Southern Ocean form the basis of this study, although the examination is conducted following a comprehensive review of the legal and other factors contributing to the development of IUU fishing as well as the applicable international law.
Asia-Pacific fishing livelihoods
Where fishing livelihoods come from and where they are going are simple questions with no simple answers. Using examples of small-scale fisheries in Asia-Pacific, Fabinyi and Barclay offer eloquent analyses of how fishing livelihoods are shaped, resting on a relational approach idea
