This paper assists African countries and Regional Economic Communities (RECs) in improving the integration of the fisheries and aquaculture sector into policy documents dealing with poverty eradication, foreign currency generation, food security, the ecosystem approach to fisheries and aquaculture, and gender mainstreaming. For this purpose, the paper assesses whether the sector is adequately embedded in policy documents in Africa at both the country and regional level. The analysis addressed 54 African countries and 8 RECs. As a policy assessment tool, the multi-criteria analysis has been applied to compare two options - "relevance" and "inclusion" - across several performance dimensions. Based on the assessments performed, the extent of "integration" and "discrepancy" of the fisheries and aquaculture sector in policy documents has been calculated.The findings showed countries where the relevance of fisheries and aquaculture is not recognized, and where advocacy should be oriented towards raising awareness of the contribution of this sector. On the other hand, there are countries with a modest fisheries and aquaculture sector that have nevertheless implemented policies and reached high levels of inclusion. Recommendations both at country and REC level include improving the availability of information on the sector's value chain to enhance visibility and awareness of its importance.

Aquaponics is a revolutionary system for growing plants by fertilizing them with the waste water from fish in a sustainable closed system. A combination of aquaculture and hydroponics, aquaponic gardening is an amazingly productive way to grow organic vegetables, greens, herbs, and fruits, while providing the added benefits of fresh fish as a safe, healthy source of protein. On a larger scale, it is a key solution to mitigating food insecurity, climate change, groundwater pollution, and the impacts of overfishing on our oceans.

"Aquaponic Gardening "is the definitive do-it-yourself home manual, focused on giving you all the tools you need to create your own aquaponic system and enjoy healthy, safe, fresh, and delicious food all year round. Starting with an overview of the theory, benefits, and potential of aquaponics, the book goes on to explain:

• System location considerations and hardware components
• The living elements--fish, plants, bacteria, and worms
• Putting it all together--starting and maintaining a healthy system

Aquaponics systems are completely organic. They are four to six times more productive and use ninety percent less water than conventional gardens. Other advantages include no weeds, fewer pests, and no watering, fertilizing, bending, digging, or heavy lifting--in fact, there really is no downside Anyone interested in taking the next step towards self-sufficiency will be fascinated by this practical, accessible, and well-illustrated guide.

Sylvia Bernstein is the president and founder of The Aquaponic Source. An internationally recognized expert on aquaponic gardening, Sylvia speaks, writes, and blogs extensively about this revolutionary technique.

Becoming Salmon is the first ethnographic account of salmon aquaculture, the most recent turn in the human history of animal domestication. In this careful and nuanced study, Marianne Elisabeth Lien explores how the growth of marine domestication has blurred traditional distinctions between fish and animals, recasting farmed fish as sentient beings, capable of feeling pain and subject to animal-welfare legislation. Drawing on fieldwork on and off salmon farms, Lien follows farmed Atlantic salmon through contemporary industrial husbandry, exposing how salmon are bred to be hungry, globally mobile, and "alien" in their watersheds of origin. Attentive to both the economic context of industrial food production and the materiality of human-animal relations, this book highlights the fragile and contingent relational practices that constitute salmon aquaculture and the multiple ways of "becoming salmon" that emerge as a result.

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.

This exciting new book provides practical guidance and advice for individuals who are seeking to manage and develop a successful aquaculture business. Starting with an overview of the types of challenges faced by managers of aquaculture businesses, the book then presents and contrasts the differences in challenges faced by new, start-up businesses and those that have been in business for many years. The book includes step-by-step guidance on how to find key markets, locate customers and determine their preferences, how to develop estimates of capital requirements for land, construction of buildings and production facilities, and to purchase equipment. Guidance is given to the reader on practical aspects of developing a financing plan, including the key financial statements that show early indication of potential problems. Comprehensive coverage is also provided of the various types of permits and regulations, as well as the magnitude of costs and delays that can occur for an aquaculture business to be in compliance. Finally, advice is given on keeping an eye on emerging trends, signs of changing consumer preferences and demand, and external threats and opportunities. Written by Carole Engle, known and respected worldwide, Aquaculture Businesses is an essential internationally-applicable resource for aquaculture entrepreneurs and business men and women who are the management-level decision makers for new start-up businesses, as well as for existing businesses that need to continue to grow and change with market dynamics. All aquaculture farm owners, and suppliers to the industry, should have this excellent resource to hand. Libraries in all universities and research establishments where aquaculture, business studies, economics or marketing are studied and taught should have copies of this book on their shelves.

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.

As the world's demand for food from aquatic environments continues to increase, the importance of performing aquaculture in an environmentally responsible manner also increases.

The aim of this important and thought-provoking book is to stimulate discussion among aquaculture's modern scientific, education and extension communities concerning the principles, practices and policies needed to develop ecologically and socially sustainable aquaculture systems worldwide. "Ecological Aquaculture" provides fascinating and valuable insights into primitive (and often sustainable) culture systems, and ties these to modern large-scale aquaculture systems.

The book is edited, and authored to a considerable degree, by Barry Costa-Pierce who has assembled a team of some of the leading thinkers in the field, providing information spanning a spectrum of activities from artisanal to high technology approaches to producing aquatic organisms in a balanced and environmentally-friendly way.

"Ecological Aquaculture" is an essential purchase for all aquaculture personnel involved in commercial, practical and research capacities. Libraries in research establishments and universities where aquaculture, biological, environmental and aquatic sciences are studied and taught should have copies of this book available on their shelves.

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.

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.

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.
