Over the past few years, it has become more and more obvious that fish farming will become increasingly important in the future. As fish farming moves into its industrial phase, technology will be an important factor in determining its successful development. It is therefore important for scientists & representatives from the aquaculture industry to meet to define state of the art and explore future development of fish farming technology for different fish species. 81 papers and abstracts were presented at the conference. The proceedings reflect the different sections of the conference: the plenum sessions and three parallel sessions: Juvenile marine fish, open production plants, closed production plants and poster sessions.

This volume is an outcome of the annual meeting of the crustacean society symposia on Crustacean Issues 2. It examines issues in contemporary carcinology. The volume emphasises on larval and postlarval growth in decapods.

Estuaries in every country exemplify the same paradox - they are among the most productive ecosystems and also among the most impacted by anthropogenic activities. And although estuarine biodiversity is key to the ecological and economic health of coastal regions, estuaries are exposed to toxic effluents transported by rivers from remote and nearby conurbations and industrial and agricultural concerns, putting them at risk. Increased attention to environmental issues highlights the fragility and importance of estuaries and brings to the forefront the need for an up-to-date assessment of techniques. Environmental Assessment of Estuarine Ecosystems: A Case Study describes a comparative, multidisciplinary ecotoxicological study of two contrasting estuaries in France. Based on the results of this study, the book presents generalizations about how different techniques might be applied and interpreted in future, similar studies assessing the ecotoxicological status of these vital coastal systems. With contributions from international experts, this reference covers all aspects of estuaries from the physiological to the economical. It introduces the state-of-the-art science required to investigate ecotoxicological problems in many estuaries all over the world. Although carefully focused on a specific region, this book covers a broad range of environmental issues and solutions, demonstrating how various pieces of information can be integrated into a sound assessment. Understanding the observations about this region and the techniques used for its assessment provide a benchmark for assessing, remediating, and applying new developments to other estuaries.

It considers global economic issues concerning fishing rights, looks at joint ventures between nations, and considers law enforcement efforts. The volume devotes a section to sea lanes and another to off shore mineral deposits. It also considers current and growing problems and possible solutions regarding pollution:

Over the past few years, there has been significant growth and development in the salmon farming industry. In order to be successful, practitioners not only need to know how the salmon lives and survives in the wild but, amongst other things have knowledge of disease, production processes, economics and marketing.The Handbook of Salmon Farming is a practical guide that covers everything the practitioner needs to know, and will also be of great use to academics and students of aquaculture and fish biology. The editors have invited contributions from experts in academia, the fish industry and government to provide an up-to-date and comprehensive handbook.

Key features: Takes a quantitative approach to the science of aquaculture Covers the complete landscape of the scientific basis of fish culture Promotes problem solving and critical thinking Includes sample problems at the end of most chapters Guides the reader through the technical considerations of intensive aquaculture, including fish growth rates, hydraulic characteristics of fish rearing units, oxygen consumption rates in relation to oxygen solubility and fish tolerance of hypoxia, and water reconditioning by reaeration and ammonia filtration. Discusses the environmental effects of aquaculture Includes a chapter on hatchery effluent control to meet receiving water discharge criteria Aquaculture Technology: Flowing Water and Static Water Fish Culture is the first book to provide the skills to raise fish in both a flowing water and a static water aquaculture system with a pragmatic and quantitative approach. Following in the tradition of the author's highly praised book, Flowing Water Fish Culture, this work will stand out as one that makes the reader understand the theory of each type of aquaculture system; it will teach the user "how to think" rather than "what to think" about these systems. The book presents the scientific basis for the controlled husbandry of fish, whether it be in a stream of water or a standing water pool. Part 1, Flowing Water Fish Culture, is a major revision of the author's initial book and includes greatly expanded coverage of rearing unit design criteria, fish growth and the use of liquid oxygen, hatchery effluent control, and recirculating systems. Part 2, Static Water Fish Culture, presents the scientific basis of fish culture in standing water systems including nutrient and dissolved gas dynamics, pond ecology, effects of fertilization and supplemental feeding, water quality management and representative static water aquacultures. Aquaculture Technology conveys the science in a manner appropriate for use by university students and teachers and others involved in fish production and aquaculture research and development worldwide. It will enable the reader to adapt to changing technologies, markets, and environmental regulations as they occur.

Paddlefish have become of increasing interest to the aquaculture community in recent years, particularly as a potential new source of seafood and caviar. Native to North America, paddlefish show great promise both domestically and internationally as a commercially viable farmed species.

Since time before memory, large numbers of salmon have made their way up and down the Klamath River. Indigenous management enabled the ecological abundance that formed the basis of capitalist wealth across North America. These activities on the landscape continue today, although they are often the site of intense political struggle. Not only has the magnitude of Native American genocide been of remarkable little sociological focus, the fact that this genocide has been coupled with a reorganization of the natural world represents a substantial theoretical void. Whereas much attention has (rightfully) focused on the structuring of capitalism, racism and patriarchy, few sociologists have attended to the ongoing process of North American colonialism. Salmon and Acorns Feed Our People draws upon nearly two decades of examples and insight from Karuk experiences on the Klamath River to illustrate how the ecological dynamics of settler-colonialism are essential for theorizing gender, race and social power today.

Gibbons examines the water supply problem through five case studies. The problems faced by these regions and the methods suggested to overcome them provide excellent models for the entire United States. The case studies---typically, expanding supplies---but economic efficiency principles lead to emphasizing managing the demand. In many cases, this means reducing demand by raising prices.

The maintenance of the freedom of fishing in the face of the changing circumstances that were occurring at the time of this title's original publication in 1973 had produced several damaging consequences. It had led to considerable waste, in both biological and economic terms, and had been the source of increasing conflict. This waste can only be prevented by the adoption of management measures and by the removal of the condition of free and open access. This book explores various techniques for this, and will be of interest to students of environmental management.

To properly conserve, restore and manage riverine ecosystems and the services they provide, it is pertinent to understand their functional dynamics. Growing human populations and high dependency on natural resources in developing countries have exerted pressure on land and water resources. However, there is a major knowledge gap concerning the influence of human activities on the functioning of tropical rivers in terms of organic matter processing and energy sources supporting riverine consumers. This thesis explores the functioning of tropical upland streams and savanna rivers by assessing the spatial and temporal dynamics in organic processing under different land-use and discharge conditions and the resultant influence on energy sources for riverine consumers. This thesis contributes to the theories of river functioning and has improved understanding of the functioning of African tropical streams by identifying a diverse macroinvertebrate shredder guild and determining its role in organic matter processing. This thesis also shows that large mammalian herbivores enhance terrestrial-aquatic food web linkages in African savanna rivers via the transfer of organic matter. The findings of this researcht are useful for defining future research needs and actions for sustainable management of agriculturally influenced streams and savanna rivers in landscapes witnessing declining wildlife populations and changing land uses.

A comprehensive study of pond fisheries. Topics include the organisation and construction of fish ponds, production processes in fish farms for warmwater carp and cold-water trout, and irrigation networks and reservoirs constructed for multipurpose exploitation.

For their great commercial importance as a human food delicacy, crayfish are now becoming of wider interest to molecular biologists, and also to conservationists due to the fact that in some countries many of the native crayfish species are under threat from human activity, disease, and competition from other introduced crayfish species. Helmed by three editors in Japan, Europe, and the US, this book invites contributions from experts around the globe, covering the conservation status and biology of all endangered species, taxonomy, and distribution of crayfishes worldwide.

This book focuses on latest information on the biology and ecology of the three bluefin tuna species: the Pacific (Thunnus orientalis), Atlantic (T. thynnus), and southern bluefin tuna (T. maccoyii). In the book, the phylogeny and basic ecological information such as early life history, age and growth, and food habits are covered. Information related to migratory ecology, and important biological aspects such as metabolism and energetics, swimming performance, schooling, visual physiology, and reproductive physiology are also included. Furthermore, new research insights about various kinds of mathematical models for bluefin tuna ecology are introduced. All the chapters are contributed by active scientists engaged in bluefin tuna research. The intent of this book is to contribute to a better understanding of the biology and ecology of bluefin tuna, and encourage undergraduate and graduate students who read this book to become bluefin tuna scientists who can contribute to further understanding of the biology and ecology of bluefin tuna.

The genus Perca includes only three species of fish, but they are ubiquitous and abundant in freshwater and brackish environments of the northern hemisphere, from North America to Europe and Asia. These species are important both ecologically and economically. In Biology of Perch, world-renowned specialists review and update the biology of these fish. The book opens with a review of the genetic makeup of this complex assemblage from early post-glacial dispersion to the colonization of new habitats. The influences of geomorphological and biological factors on the dispersal of yellow perch (Perca flavescens) are explored. Two case studies exploit unique historical databases to follow population dynamics of yellow perch and European perch (P. fluviatilis) and to demonstrate how fisheries and habitat management can drastically influence the fate of fish populations. Three other chapters are dedicated to the general reproductive physiology, parasitology, and behavior of Perca species. The third species, the Balkhash perch (P. schrenkii), is a rare and threatened species of the Balkans, and a chapter is dedicated to its biology. The book ends with a review of the use of Perca species around the world as sentinels of ecological integrity and biomonitors in ecotoxicological studies.

Discusses the importance, threats, and management of biodiversity of freshwater ecosystems Provides detailed coverage of modern and updated techniques used in the evaluation and conservation of freshwater biodiversity Looks at the impact of pesticides pollution on freshwater environs on aquatic and terrestrial life Reviews how global climate change affects freshwater biodiversity

Freshwater, brackish and marine ecosystems are particularly impacted by the effects of climate change and global warming. A global rise in water temperature and acidification of the aquatic environment will continue even if we can significantly reduce the current output of greenhouse gasses. Increases in water temperature will affect the life cycle, physiology, behaviours, distribution and community structure of aquatic organisms, especially fish. This important new text on climate change, and its effects on selected non-infectious disorders of fish, contains contributions by internationally recognized experts who have contributed significantly to our knowledge in this area. Comprehensive and thought provoking, the text details abiotic and biotic environmental changes associated with climate change and their effects on fish in tropical, subtropical and temperate waters. It proceeds to cover in detail developmental, physiological and metabolic disorders of fish. Outlining both current and expected changes in aquaculture systems due to climate change, plus suggestions for further studies, this contemporary text is key reading for biologists, aquatic ecologists, fish health consultants, veterinarians, policy makers and all those involved in fish health and the environment.

Fish constitute an important natural renewable resource and any reduction in their ability to propagate as a result of human interference may have significant socioeconomic consequences. The negative effect of human activity on sex differentiation and reproductive output in fish is so diverse that it has been difficult to encompass it in a single book. This book serves as the first attempt to do so. Unlike in mammals, the expression of a host of sex differentiation genes in fish is mostly controlled by environmental factors. Not surprisingly, environmental sex differentiation is ubiquitous in fish. Overexploitation by capture fisheries does not disrupt sex differentiation but crowding in aqua-farms does, by reducing accessibility to food supply. Some of the man-made chemicals routinely used worldwide mimic endogenous hormones. For example endosulfan, which is widely used in developing countries, disrupts endogenous hormones and feminizes fish. For the first time, this book views endocrine disruption from the point of labile early life and non-labile adult stages. It shows that sex can irreversibly be reversed, when exposed to endocrine disrupting chemicals (EDCs) during early labile stages but reversibly impairs reproductive output on exposure to EDCs during non-labile adult stage. A consequence of climate change, elevated temperature, and declining oxygen and pH levels is that it masculinises genetic female fish. Fish display a remarkable ability to postpone the labile period. Besides postponement, some primary and tertiary gonochores have two distinct labile periods amenable to temperature and hormonal manipulations. Hermaphrodites have retained the period until the end of the adult stage and are capable of sex change/reversal more than once in both male and female directions.

Biodiversity loss in terrestrial environments associated with human activities has been appreciated as a major issue for some years now. What is less well documented is the effect of such activities, including climate change, on marine biodiversity. This pioneering book is the first to address this important but neglected topic, which is likely to be the key challenge for marine scientists in the near future. Using a multidisciplinary and a holistic approach, the book reveals how climatic variability controls biodiversity at time scales ranging from synoptic meteorological events to millions of years and at spatial scales ranging from local sites to the whole ocean. It shows how global change, including anthropogenic climate change, ocean acidification and more direct human influences such as exploitation, pollution and eutrophication may alter biodiversity, ecosystem functioning and regulating and provisioning services. The author proposes a theory termed the 'macroecological theory on the arrangement of life', which explains how biodiversity is organized and how it responds to climatic variability and anthropogenic climate change. The book concludes with recommendations for further research and theoretical development to identify oceanic areas in need of observation and gaps in current scientific knowledge. Many references and comparisons with the terrestrial realm are included in all chapters to better understand the universality of the relationships between biodiversity, climate and the environment. The book will serve as a textbook for all students and researchers of marine science and environmental change, but will also be accessible to the more general reader.
