Aquaculture now supplies half of the seafood and fisheries products consumed worldwide and is gaining international significance as a source of food and income. Future demands for seafood and fisheries products can only be met by expanded aquaculture production. Such production will likely become more intensive and will depend increasingly on nutritious and efficient aquaculture feeds containing ingredients from sustainable sources.
To meet this challenge, Nutrient Requirements of Fish and Shrimp provides a comprehensive summary of current knowledge about nutrient requirements of fish and shrimp and supporting nutritional science. This edition incorporates new material and significant updates to information in the 1993 edition. It also examines the practical aspects of feeding of fish and shrimp.
Nutrient Requirements of Fish and Shrimp will be a key resource for everyone involved in aquaculture and for others responsible for the feeding and care of fish and shrimp. It will also aid scientists in developing new and improved approaches to satisfy the demands of the growing aquaculture industry.

case studies of successful governance models could be referred to by others in order to improve the management of the sector. This is the initial step toward compiling stories of aquaculture successes, and the editorial team is to be congratulated for its great efforts. In approaching this difficult assignment, the team benefited from the leadership of the Network of Aquaculture Centres for Asia and the Pacific (NACA), and the support of the World Fisheries Trust (WFT) as well as the Institute for International Sustainable Development (IISD) of Canada. We hope that the team will continue its endeavor in producing other aquaculture success stories, also from other regions of the world. Rome, Italy Jiansan Jia Pr eface We are moving into a turbulent and an uncertain era, particularly in respect of the future food needs. Given the push to sustainability, the rise in food prices, and the impending concerns around climate change and related complexity on providing the food needs for an increasing global population, it is time to address coping strategies. It is in this context that the issue on where will aquaculture development move in the future is taken up.

Norwegian spring-spawning herring and Northeast Arctic cod are two of the largest and commercially most important fish stocks in the North Atlantic. Both these stocks have their spawning fields along the Norwegian coast and they have been the major target species for Norwegian fisheries for a millennium. They are also among the few fish stocks in the world which have been systematically investigated and monitored for more than a century. The scientific results, arrived at early in the 20th century for these two stocks, formed the basis for much of the development in international fisheries science later on. This book describes how fisheries, fisheries science, and management for Norwegian spring-spawning herring and Northeast Arctic cod developed during the 20th century. Over time, both populations developed serious decline in stock size and yield due to overfishing. The herring stock was in a state of collapse for about 20 years. Management measures that were then introduced permitted both stocks to recover in the 1990s. The contributors to the book have all been working as fisheries scientists at the Institute of Marine Research in Bergen.

Ponds are a primary production system to a wide variety of freshwater fish species. Each species have specific and unique nutrient needs and successful pond fertilization is critical to a successful aquaculture enterprise." Aquaculture Pond Fertilization: Impacts of Nutrient Input on Production "provides state-of-the-art information for successful fertilization strategies for a broad range of pond-raised species.

"Aquaculture Pond Fertilization "attempts to rectify the seemingly contradictory nutrient recommendations by clearly defining the goals of specific types of aquaculture. Chapters are divided into three sections: The first reviews basic concepts in fertilization applicable to all pond-based production. The second looks at specific nutrient management approaches. The third and final section of chapters looks specifically at key freshwater pond species ranging from tilapia to perch and discusses specific fertilization needs for the successful rearing of these in-demand fish.

Looking across species with chapters contributed by leaders in the field "Aquaculture Pond Fertilization" provides succinct single-volume coverage of an oft-neglected, but vitally important topic in aquaculture production.

The principal themes of this 1997 book are stress and health in fish. Stress is of central concern in aquaculture, as the various stressors which accompany intensive fish husbandry can predispose the fish to compromised growth and health, and promote disease. The book comprises a comprehensive collection of chapters which describe potential stressors and the stress responses of fishes, as well as relevant information about the effects of factors such as nutrition. A discussion of various methods of detecting stressed states in fish in the lab as well as in the field is also included. In addition to the physiological stress response as manifest in changes in the endocrine system or acid-base and ionic balance, behavioural aspects of stress in fish are also covered.

Grey mullets are extremely important fish which are cultured or farmed in many countries, especially in the Mediterranean and South-East Asia. Mullets can be fed on a variety of food; this flexibility of feeding, together with the wide salinity of temperature tolerance, make these fish particularly suitable for agriculture. This 1981 volume considers all the aspects of these important food fish which are of relevance to their culture. After a discussion of the taxonomy and means of identification, both of adult fish and fry, the various authors consider reproduction, growth and feeding. The latter part of the book is about capture and artificial propagation, in fresh and brackish conditions. The final chapter is concerned with the relevant diseases and parasites of mullets (Mugilidae).

The world's marine fisheries are in trouble, as a direct result of overfishing and the overcapacity of fishing fleets. Despite intensive management efforts, the problems still persist in many areas, resulting in many fisheries being neither sustainable nor profitable. Using bio-economic models of commercial fisheries, this book demonstrates that new management methods, based on individual or community catch quotas, are required to resolve the overfishing problem. Uncertainty about marine systems may be another factor contributing to overfishing. Methods of decision analysis and Bayesian inference are used to discuss risk management and the precautionary principle, arguing that extensive marine reserves may be the best way to protect fisheries, alongside a controlled catch quota system. This book will be of interest to environmental scientists, economists and fisheries managers, providing novel insights into many well-known but poorly understood aspects of fisheries management.

Shrimp is the most important commodity, by value, in the international seafood trade. The shrimp industry has grown exponentially in the last decades, and growth is expected to continue for years to come. For future success in the shrimp industry, shrimp farmers and aquaculture scientists will find a thorough knowledge of the economics, market, and trade as important as an understanding of disease management or husbandry.

"Shrimp Culture: Economics, Market, and Trade" brings together recent findings of researchers from around the world working in various aspects of the economics of shrimp farming. This volume covers all major aspects of the economics, trade, and markets for shrimp worldwide, with chapters written by experts from major consuming countries such as the U.S.A. and major providers such as China, Thailand and Brazil. The book has been carefully edited by PingSun Leung and Carole Engle, both well known and respected internationally for their work in this area.

"Shrimp Culture" is an essential purchase for everyone involved in this massive industry across the globe.

The freshwater eels, the Anguillids, have increasingly become the focus of attention for fisheries managers, scientists, researchers, policy makers, conservation bodies and other stakeholders. These species can be seen as a bellwether for issues affecting aquatic ecosystems - their steep decline and the management initiatives to try and reverse this trend, touch on subjects as diverse as disconnected waterways, loss of habitat, novel parasites, pollution, over-fishing and climate change. There are some 16 species of the Anguilla genus and all exhibit similar lifestyles, growing in waters often far-removed from their marine spawning grounds. These enigmatic, contradictory and confounding species share similar challenges and pressures wherever they are found. This book was generated from the 1st UK International Eel Science Symposium which was held at the Zoological Society of London (ZSL) in June 2017. Hosted by the Institute of Fisheries Management (IFM), the ZSL, and the Environment Agency (EA), the Symposium was heralded as a success, with over 180 delegates in attendance. Many of the world's top eel specialists attended or gave presentations across a diverse range of subjects. This was one of the Symposium's, and now the book's great strengths - its diversity of subjects and authors. Many countries are represented within the book, from across Europe and as far afield as New Zealand, South Africa, Vanuatu, French Polynesia, Japan, Canada and the USA. The EA and IFM have collaborated to produce this landmark book which includes a mix of cultural, scientific and management information which will be invaluable to anyone with a professional or personal interest in these mysterious fish, including ichthyologists, fisheries scientists and managers, aquaculture personnel, environmental biologists and ecologists, marine and freshwater biologists, vertebrate zoologists, animal behaviourists and students studying in all these areas. Libraries in all universities and research establishments where these subjects are studied and taught should have copies on their shelves.

There is considerable global interest in the culture of finfish species both for cold and warm water aquaculture development and growth. Essential information on the biology, domestication and aquacultural characteristics of a wide selection of novel and established species is provided in the form of technical sheets, species descriptions and information on current rearing practices, making this a must-have reference in the field of aquacultural science. The book also offers a basic framework in order to support investment strategies for research and developement efforts aimed at the emergence of a profitable finfish aquaculture industry and presents a rationale for species diversification, different approaches to species selection and basic economical and market considerations governing the launch of strategic development and commercialization efforts.

This book is a study of the effect of occupation on industrial behaviour and how occupation affects social, community and family life. The fishing industry was one of the last to experience the Industrial Revolution. In East Anglia, steam propulsion was introduced within the working life of the oldest of those interviewed for this book, and a number of radical changes in working practices, capital cost and technical development were concentrated into the brief period 1880-1914. As these changes occurred with different timing and force in the two major sectors of the industry - trawling and drifting - East Anglia is an ideal location in which to consider the effect of the forces and relations of production: the fishermen's industrial, social and political attitudes are related to their specific work experience.

The current high demand for fish and increased awareness of the role of the environment in supporting human well being has led to a situation where attitudes to inland water resources are changing rapidly.

Trends in resource use and environmental impact are very evident in inland waters which are particularly vulnerable as they act as collectors of all the activities occurring in their basins and rank as some of the most endangered ecosystems in the world. The principle changes influencing the evolution of the aquatic resource for fisheries are described in this book, which has been compiled for the Food and Agriculture Organization of the United Nations.

Detailed coverage of environmental aspects relating to fish biology is a key feature of this book which will be of great use to students and individuals in fish biology, fisheries, aquaculture and environmental sciences.

Traditional accounts of whaling celebrate exotic locales and dangerous exploits but shed little light on the lives of the men who went to sea. Rites and Passages places sailors at the center of a social history of whaling and explores the ways in which the history of the sea and the history of the shore have intersected. Drawing on the evidence of ship logs and sailors' letters and journals, Margaret S. Creighton examines American whalemen during the industry's peak--the mid-nineteenth century--and argues that whaling life and culture were shaped by both the American mainland and by the exigencies of ocean life. Unlike other accounts of seafaring, this work brings gender into the maritime equation, not only with a discussion of the ways that women figured in this male-dominated world, but also with an examination of the ways that seafaring served as a rite of passage into manhood. Professor of History at Bates College, Margaret Creighton is the author of Dogwatch and Liberty Days: Seafaring Life in the 19th Century and co-editor of Iron Men and Wooden Women: Gender and Maritime History. She has been guest curator at The Peabody Museum of Salem and the U.S.S. Constitution Museum of Boston.

The fundamentals of making up nets from machine--made netting are set out with such clarity and simplicity that the book has proved a boon to fishermen around the world. Early chapters describe the principles of mesh size and the run of knots in machine netting, and are followed by detailed descriptions of net making machines and the principles of hanging netting. On actual fishing nets, descriptions are given of seine net patterns, various trawl nets, pound nets such as salmon nets with detailed drawings, surround nets of the lampara type and ring nets with their design, construction and methods of working. A useful dictionary of fishing gear and terminology explains 1,000 terms.

As the ecosystem-based trend in fisheries management continues to be implemented worldwide, a thorough background of this new management approach and resulting implementation strategies is needed. "Ecosystem-Based Fisheries Management in the Western Pacific" presents a full picture of the process changes used in switching from target species based management to EBFM, using a region that is at the forefront of this widely accepted movement.

"Ecosystem-Based Fisheries Management in the Western Pacific" is the outgrowth of a series of three workshops convened by the Western Pacific Regional Fishery Management council. The book follows the logical approach of each workshop, beginning with an assessment of the current state of fisheries management, transitioning through the data sources and modeling systems used to advance EBFM, and ending with practical methodologies for more thorough global implementation in the future.

Contributed by experts from the Pacific regions as well as the UK and Non-pacific States, this book is one of the first available compendiums on this important movement and will be applicable to fisheries scientists and researchers, fisheries managers, policy makers, and social scientists worldwide

Alaska pollock is everywhere. If you're eating fish but you don't know what kind it is, it's almost certainly pollock. Prized for its generic fish taste, pollock masquerades as crab meat in california rolls and seafood salads, and it feeds millions as fish sticks in school cafeterias and Filet-O-Fish sandwiches at McDonald's. That ubiquity has made pollock the most lucrative fish harvest in America-the fishery in the United States alone has an annual value of over one billion dollars. But even as the money rolls in, pollock is in trouble: in the last few years, the pollock population has declined by more than half, and some scientists are predicting the fishery's eventual collapse. In Billion-Dollar Fish, Kevin M. Bailey combines his years of firsthand pollock research with a remarkable talent for storytelling to offer the first natural history of Alaska pollock. Crucial to understanding the pollock fishery, he shows, is recognizing what aspects of its natural history make pollock so very desirable to fish, while at the same time making it resilient, yet highly vulnerable to overfishing. Bailey delves into the science, politics, and economics surrounding Alaska pollock in the Bering Sea, detailing the development of the fishery, the various political machinations that have led to its current management, and, perhaps most important, its impending demise. He approaches his subject from multiple angles, bringing in the perspectives of fishermen, politicians, environmentalists, and biologists, and drawing on revealing interviews with players who range from Greenpeace activists to fishing industry lawyers. Seamlessly weaving the biology and ecology of pollock with the history and politics of the fishery, as well as Bailey's own often raucous tales about life at sea, Billion-Dollar Fish is a book for every person interested in the troubled relationship between fish and humans, from the depths of the sea to the dinner plate.

Climate change with global warming is not disputed by the vast majority of scientists and the aquatic system is most affected. A global rise in water temperature and acidification of the aquatic environment will continue even if we can significantly reduce the current output of the two most important greenhouse gasses (carbon dioxide and methane). These and other environmental changes will affect fish health which includes infectious pathogens. This important new text is the second volume on climate change and fish health. It covers changes to the freshwater ecosystem and their current and expected effects on selected infectious diseases of fish. The book represents contributions by over 50 experts from 18 countries. Comprehensive and thought-provoking, the book details abiotic and biotic environmental changes in temperate and tropical freshwater ecosystems, sequestrations of atmospheric carbon dioxide and effects on infectious diseases (12 microbial and 10 parasitic) in economically important fish in tropical, subtropical and temperate waters. The text is key reading for fish disease scientists, aquatic ecologists, fish health consultants, veterinarians, policy makers and all who are interested in fish health and the environment.

Fish nutrition can be the deciding factor between a robust and healthy farmed fish population and low aquaculture production. In an age where chemicals and antibiotics are under greater scrutiny than ever, a strong understanding of the role of nutrients and feed additives is essential in the aquaculture industry. Dietary Nutrients, Additives and Fish Health is a comprehensive review of dietary nutrients, antinutritional factors and toxins, and non-nutrient dietary additives, and their effects on fish performance and immune system function, as well as overall health. The book opens with an overview of fish immune systems and health. Subsequent chapters delve into proteins and amino acids, lipids and fatty acids, carbohydrates, beta glucans, vitamins, minerals, antinutrients, mycotoxins, nucleotides, prebiotics, probiotics, organic acids and their salts, and plant extracts and their impacts on fish health, growth, and development. The text then concludes with a chapter on feeding practices. Authored by leaders in aquaculture, Dietary Nutrients, Additives and Fish Health will be an invaluable resource to graduate students, researchers and professionals alike.

Aquaculture exemplifies the ongoing global struggle to strike a sustainable balance between the conflicting needs of a rapidly increasing world population, human health, ecosystem health, the welfare of wild and domesticated animals, and the economic principles of globalized economies. On the one hand, aquaculture has great potential for providing us with a healthy and nutritious food supply whilst alleviating pressure on captive fisheries and reducing fisheries-induced habitat destruction, overfishing, genetic modification of wild populations, and wholesale waste of bycatch. On the other hand, aquaculture relies heavily on clean water, an increasingly precious (and dwindling) resource that is subject to intense pressure of being used for many competing objectives. This concise primer introduces students to the basic concepts, opportunities, and challenges of aquaculture with an emphasis on ecological considerations. It provides a critical assessment of current aquaculture practices from a broad, interdisciplinary perspective and from the standpoint of how best to align the two major (and often conflicting) goals of future aquaculture development: minimizing reliance on ecosystem services whilst maximizing productivity. A Primer of Ecological Aquaculture provides an accessible and authoritative overview for a wide range of undergraduate majors ranging from biology, engineering, and environmental policy to business and management. It will also appeal to a more general academic audience who wish to gain a current overview of the field.
