Bringing together recent advances in the research into the ecology and biology of brown and sea trouth, this book places them in their ecological setting and shows how an understanding of their biology and environment aids efficient management of both fish stocks and the surroundings. In particular, it concentrates on the management of the fish in natural flowing waters, and discusses issues such as how to determine an efficient feeding strategy and the influence of hatchery stocks upon wild populations. A detailed case study focusing on the French experience is of especial interest. Biology and Ecology of the Brown Sea Trout synthesizes the considerable body of research available and provides a significant tool for the better management and conservation of these important fish.

The Fourth International Symposium on Paleolimnology was held in 1985 from 2 -7 September at Lake Ossiach and close to the Austrian village of Ossiach (mentioned in historical records for the first time in 1028). After the opening speeches a performance by a Carinthian folk-dance group gave the participants a taste of the rural atmosphere of Austria's southernmost federal land. 125 paleolimnologists presented and discussed papers during the meetings and many participated About in the pre-congress excursion devoted to the Salzkammergut, and in the post-congress excursion to Neusied- lersee. There was a half-day trip during the symposium to Langsee which is well known from the pioneer work carried out by Professor D. G. Frey more than 30 years ago. In addition to methodological papers most of the special fields of paleolimnology were covered. Special attention was given a.o. to geochemistry, pigments and meromictic lakes. The geographical range of the sites investigated was quite wide. In this connection it is regrettable that none of the expected Soviet colleagues was able to attent the symposium. Under the presidency of Professor D. G. Frey the present members of the international organizing committee (Prof. S. R. Brown, Prof. E. S. Deevey, Prof. F. Oldfield and Dr. M. Ralska-Jasiewiczowa) contributed considerably to the success of the symposium. Likewise our thanks goes to those who helped behind the scenes (Mr. M. Bobek, Mr. M. Fusko, Mrs. A. Klenner, Ms. B. Stipanits and Ms. K. Wolter).

The structure and functioning of eutrophicated aquatic ecosystems has received considerable attention from limnologists as well as water managers in recent years. Stress has often been on pelagic food webs of deeper lakes whilst littoral systems or shallower lakes have been less thoroughly investigated. Since Dutch aquatic systems are shallow, as a rule, they form a notable exception. But here, too, the orientation was often on pelagic food webs. The present study has a clearly different scope in that it takes the water plant as prime perspective. The editors consider water plants to be the key component in shallow aquatic ecosystems. They have compiled work on one water plant species, Potamogeton pectinatus L., and from one lake, Lake Veluwe, as a typical case, and set out to explain the fluctuations in abundance of this water plant as influenced by eutrophication. A working hypothesis on the mechanism responsible for water plant decline during eutrophication was adopted and tested in a combination of field and laboratory work. A simulation model, SAGAI, for the water plant P.pectinatus was developed and proved to fit independent data very well. The work started out as a joint effort of a single project team in the Department of Nature Conservation of Wageningen Agricultural University, but the present volume has benefited considerably from the inputs of several invited colleagues, as the list of contributors witnesses. The editors have made an invaluable contribution to the understanding of shallow aquatic ecosystems and to their scientifically based and sustainable management.

Marine pollution occurs today in varied forms--chemical, industrial, and agricultural-and the sources of pollution are endless. In recent history, we've seen oil spills, untreated sewage, eutrophication, invasive species, heavy metals, acidification, radioactive substances, marine litter, and overfishing, among other significant problems. Though marine pollution has long been a topic of concern, it has very recently exploded in environmental, economic, and political debate circles; scientists and non-scientists alike continue to be shocked and dismayed at the sheer diversity of water pollutants and the many ways they can come to harm our environment and our bodies.
In Marine Pollution: What Everyone Needs to Know, Judith Weis covers marine pollution from many different angles, each fascinating in its own right. Beginning with its sources and history, the book describes in detail each common pollutant, why exactly it is harmful, why it may draw controversy, and how we can prevent it from destroying our aquatic ecosystems. Weis discusses topics like what actually happened with the Exxon Valdez, and why Harmful Algal Blooms are a serious concern. Later chapters will discuss pollutants that are only now surfacing as major threats, such as pharmaceuticals, personal care products, and metal nanoparticles, and explain how these can begin in the water and progress up the food chain and emerge in human bodies. The book's final section will discuss the effects of climate change and acidification on marine pollution levels, and how we can reduce pollution at the local and global levels.

Fish Nutrition, Fourth Edition is an up-to-date, authoritative presentation of all key elements of the nutrition of fish and crustaceans. As aquaculture is rapidly expanding, more than 200 herbivorous and carnivorous species occupy a diverse range of ecological niches, and have therefore evolved to utilize a wide array of food sources. This new edition highlights these differences and covers the complexity and challenges associated with fish nutrition, addressing nutrient requirements to produce high-quality, healthful and sustainable resources, the essential nutrients for fish species, including proteins and amino acids, vitamins, minerals and essential fatty acids, a feed quality assessment, and fish pathology. Led by a team of international experts, this edition provides readers with new information on the use of high-throughput technologies in fish nutrition research, the role of feeds on the community structure of the microbiome, and advances in essential nutrient requirements.

This book explores the nature of marine conservation based on the case study of Hinase, a fishing village in Okayama, Japan. It focuses on the fishers' self-motivated eelgrass restoration activity which has been continued for more than 30 years. This activity in Hinase recently attracted international attention as a case under the name "Satoumi" and "Marine Protected Areas" in several governmental reports, but detailed information, such as the historical background and social structure of Hinase, has not yet been analyzed. This book, therefore, fulfills this gap by providing its ethnographic information. In addition, this book offers some points for critical thinking by concluding that marine conservation activities cannot always be evaluated or arranged under the standardized approach with limited time and space. This viewpoint reaffirms the importance of local initiative and highlights the value of qualitative research to seek the way forward for promising marine conservation. This book is suitable for an academic audience in the field of social sciences, such as applied anthropology, as well as ecologists, government officials, environmentalists, and citizens who are interested or engaged in environmental issues or natural resource management.

Presenting cohesive and integrated coverage of key topics and discussing technological advances used in modern shark research, this revised edition offers a well-rounded picture for students and researchers.

The book presents recent research on marine ecology in different parts of the world. It aims to shed light on relevant topics for budding marine ecologists. The "blue soup" of Planet Earth, which comprises both biotic and abiotic components, is essential to keeping the wheel of civilization running. Four major ecosystem service categories have been identified within this context, namely provisioning services such as water, food, mangrove timber, honey, fish, wax, fuel wood, fodder and bioactive compounds from marine and estuarine flora and fauna; regulating services such as the regulation of climate, coastal erosion, coral bleaching and pollution; cultural services encompassing recreational (tourism), spiritual and other non-material benefits; and supporting services such as nutrient cycling and photosynthesis. These valuable services are obtained from various resources that must be conserved for the sake of humanity. This book presents data for each resource type, not just in the form of a simple description, but also through case studies that resulted from several research projects and pilot programs carried out in different parts of the world. Statistical tools were also used to critically analyze the influence of relevant hydrological parameters on the biotic community. Advanced research in marine and estuarine ecology is based on the use of sophisticated instruments, sampling precision, statistical tools, etc., which have also been highlighted in the book.

Planktonium is a photo project and a short film by Dutch photographer/cinematographer Jan van Ijken about the unseen world of living microscopic plankton. It is a voyage into a secret universe inhabited by alien-like creatures. These stunningly beautiful, extremely diverse, and numerous organisms are unknown to most of us because they are invisible to the naked eye. However, they are wandering beneath the surface in waters all around us and are of vital importance for all life on earth. Phytoplankton (small plant-like cells) produce half of all the oxygen on earth by photosynthesis, like plants and trees do on land. Zooplankton form the base of the food chain of aquatic life. Plankton also play an important part in the global carbon cycle. They are currently threatened by climate change, global warming and the acidification of the oceans. Jan van Ijken photographed the plankton through microscopes, revealing the beauty and delicate structures of these minute organisms in the finest detail.

Fisheries science in North America is changing in response to a changing climate, new technologies, an ecosystem approach to management and new thinking about the processes affecting stock and recruitment.

Authors of the 34 chapters review the science in their particular fields and use their experience to develop informed opinions about the future. Everyone associated with fish, fisheries and fisheries management will find material that will stimulate their thinking about the future. Readers will be impressed with the potential for new discoveries, but disturbed by how much needs to be done in fisheries science if we are to sustain North American fisheries in our changing climate. Officials that manage or fund fisheries science will appreciate the urgency for the new information needed for the stewardship of fish populations and their ecosystems. Research organizations may want to keep some extra copies for a future look back into the thoughts of a wide range of fisheries professionals. Fisheries science has been full of surprises with some of the surprises having major economic impacts. It is important to minimize these impacts as the demand for seafood increases and the complexities of fisheries management increase.

Many western limnologists have no or a very limited knowledge and understanding of limnology in the Soviet Union; the language barrier is simply too hermetic, and the threshold for making the effort (and spending the money) for obtaining translations of significant Russian works is usually too high for most Eu ropeans and North Americans. There is so much to read aside from that literature printed in the cyrillic al phabet that, not by intention or by design, but by sheer inertia, we tend to forget about it altogether. Of course, we are wrong, and we know it. Today, 'Hydrobiologia' is proud to present a theme volume by one of the active Soviet limnologist groups, ably steered by Nikolai Smirnov. Their target lake, Glubokoe ozero, is one of the better studied waters of the northern hemisphere, and the series of contributions included in this collection of papers aims both at illustrating this point and at making this interesting material widely available in a congress language. I am confident that 'Studies on Lake Glubokoe' will make a significant contribution to a well-merited better penetration of Russian science onto the world market. H. 1.

Evidence now suggests that the roles of essential fatty acids as growth promoters and as indices of health and nutrition are fundamentally similar in freshwater and marine ecosystems. Lipids in Aquatic Ecosystems integrates this divergent literature into a coordinated, digestible form.

Chapters are organized so as to discuss and synthesize the flow of lipids from lower to higher trophic levels, up to and including humans. Linkages between the production, distribution and pathways of these essential compounds within the various levels of the aquatic food webs, and their ultimate uptake by humans and other terrestrial organisms, are highlighted throughout the book. This book will be of interest to researchers and resource managers working with aquatic ecosystems.
