Book Description
As salmonids have been reared for more than a century in many countries, one might expect that principles are well established and provide a solid foundation for salmonid aquaculture. Indeed, some of the methods used today in salmonid rearing are nearly identical to those employed one hundred years ago. Areas of salmonid research today include nutrition, smolt and stress physiology, genetics and biotechnology.The purpose of this book is to provide a useful synthesis of the biology and culture of salmonid fishes. The important practices in salmonid culture as well as the theory behind them is described. This volume will be of interest to students, researchers, fisheries biologists and managers as well as practising aquaculturists.

Book Description
""" This book has been written as a guide to the management and use of formulated feeds in intensive fish and shrimp culture. While its focus is on the use of commercially pro duced feeds in intensive production systems, it is anticipated that many of the practical issues covered will be of equal interest to those fish farmers who make their own feeds and to those who use formulated feeds in less intensive systems. Feeds and feeding are the major variable operating costs in intensive aquaculture and the book is primarily in tended to aid decision making by fish farm managers in areas of feeding policy. The dramatic increases in aquaculture production seen over the past 15 years have been made possible, in large part, by gains in our understanding of the food and feed ing requirements of key fish and shrimp species. A global aquaculture feeds industry has developed and a wide range of specialist feeds is now sold. The new options in feeds and feeding systems, which are becoming available, necessitate continual review by farmers of their feeding policies, where choices must be made as to appropriate feed types and feeding methods. While growth rates and feed conversion values are the prime factors of interest to farmers, other important issues, such as product quality and environmental impacts of farm effiuents, are also directly related to feed management practices.

Book Description
Understanding the biology of the innumerable number of aquatic species on our planet is the focus of sustained research efforts. Environmental degradation, management or rehabilitation of wild stocks, and the forecasted climatic changes are fueling interest in the study of the ecology, feeding behavior, and nutrition of aquatic animals in their nat

Book Description
This extensive work focuses on an important group of temperate freshwater fish, approaching the topic from the perspectives of both biology and aquaculture. It compiles the latest research on fish belonging to the Percidae family and describes in detail all biological aspects relevant to the culture of different species, including ecology, reproductive physiology, feeding and nutrition, genetics, immunology, stress physiology and behavior. It also considers commercial fish production and fish farming topics, such as protocols for induction of gonad maturation, spawning, incubation and larval rearing. Expert contributors not only provide a critical peer review of scientific literature but also original research data, and identify effective practical techniques. The book features chapters on systematics, ecology and evolution, on development, metabolism and husbandry of early life stages and on growth, metabolism, behavior and husbandry of juvenile and grow-out stages. Furthermore, the authors consider genetic improvement and domestication, as well as diseases and health management, crucial to the readers' understanding of these fish and how they can be cultured. Both researchers of percid fish biology and aquaculture professionals who are considering intensive and pond culture of percid fishes will value this timely and comprehensive handbook.)

Book Description
The intake of food by fishes is an area of study that is of great importance to the applied sciences of fisheries and aquaculture for a number of reasons. For example a thorough knowledge of factors influencing the ingestion of feed can lead to successful manipulation of the rearing environment of cultured fishes, thereby ensuring improved growth performance and feed utilisation, and decreasing the amount of waste (and consequent pollution) per unit of fish produced. This important book, which has arisen out of a European Union COST programme, illustrates how insights into the biological and environmental factors that underlie the feeding responses of fish may be used to address practical issues of feed management. Food Intake in Fish contains carefully edited contributions from internationally recognised scientists, providing a book that is an invaluable tool and reference to all those involved in aquaculture, especially those working in the aquaculture feed industry and scientific personnel in commercial and research aquaculture facilities. This book should also find a place on the shelves of fish biologists and physiologists and as a reference in libraries of universities, research establishments and aquaculture equipment companies.

Book Description
This discipline of behavioural ecology has reached a turning point- empirical evidence in behavioural ecology has led to the reformulation of the classic explanatory theories, and new areas of interest have opened up. The study of fish provides an excellent model of the subject, allowing a concise but complete treatment of the field. This book is based on papers from the proceedings of a conference held at the Ettore Majorana Centre, Erice, Italy, provides an overview of the key developments in behavioural ecology. Four main areas of interest are covered the behavioural ecology of predator avoidance, foraging, resource defence and life histories and reproduction.

Book Description
Modern aquaculture is faced with a number of challenges, including public concern about environmental impacts and the welfare of farmed fish. A fundamental understanding of fish biology is central to finding ways to meet these challenges and is also essential for maintaining the industry's sustainability. Furthermore, the behaviour of fish under culture situations has long been ignored despite heavy commercial losses that can result from fish stressed and hence disease-prone, due to bad husbandry techniques. This important book summarises the current understanding of the behavioural biology of farmed species and illustrates how this can be applied to improve aquaculture practice. Informative and engaging, Aquaculture & Behavior brings the reader up-to-date with major issues pertaining to aquaculture. Everyone from fish farmers to upper level students will find this book a valuable and practical resource. Libraries in universities and research establishments where animal behavior, aquaculture, veterinary and biological sciences are studied and taught should have copies of this work on their shelves.

Book Description
Behavioural ecotoxicology is an emerging field dealing with the effects of environmental pollutants on the behaviour of animals. Behavioural techniques derived from experimental psychology, behavioural pharmacology and neurotoxicology are applied to detect and characterise changes in animals living in the environment exposed to various pollutants. Behavioural effects are then interpreted in an ecological context considering the long-term relevance of these changes at both the individual and population level.

Book Description
Fish and shellfish comprise annually nearly 70-million tons of the world's edible animal protein. However, because of this demand, previously vast stocks have often been exhausted to the point of near extinction. The first book of its kind in the area of freshwater/marine biodiversity, this extensive work reviews the present status of genetic resource management, its needs and constraints, various intervening human factors such as pollution and overfishing, and problems posed by different species and life-styles. This discussion of the conservation of fish and shellfish resources is illustrated by four diverse groups: Atlantic salmon, cupped oysters, common and Chinese carp, and Nile tilapia. These results, produced by the collaboration of nine leading population and production geneticists, aquaculturists, and behavioral and developmental ecologists should become a fundamental resource useful to biologists, scientists and advisors exploring current issues in the fishery sciences. - Four page color plate section - Database of key organizations for contact purposes - Foreword by Dr. Mike Strauss, Am. Assoc. for the Advancement of Science; and Dr. Peter Day, Rutgers University - Four in-depth case studies by international experts - Editors are major names in marine/freshwater fisheries science - Originally sponsored and reviewed by U.S. National Academy of Sciences
