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

Tilapia Culture, Second Edition, covers the vital issues of farmed tilapia in the world, including their biology, environmental requirements, semi-intensive culture, intensive culture systems, nutrition and feeding, reproduction, seed production and larval rearing, stress and disease, harvesting, economics, trade, marketing, the role of tilapia culture in rural development and poverty eradication, and technological innovations in, and the environmental impacts of, tilapia culture. In addition, the book highlights and presents the experiences of leading countries in tilapia culture, thus making it ideal for tilapia farmers and researchers who seek the most relevant research and information. The new second edition not only brings the most updated information within each chapter, but also delivers new content on tilapia transfers, introductions and their impacts, the use of probiotics and other additives in tilapia culture, tilapia trade, including marketing, and sustainability approaches and practices, such as management practices, ecosystem approaches to tilapia culture, and value chain analyses of tilapia farming. - Presents the biology of tilapia, including taxonomy, body shapes, geographical distribution, introductions and transfers, gut morphology, and feeding habits - Covers semi-intensive tilapia culture in earthen ponds, tanks, raceways, cages, recirculating systems, and aquaponics - Provides the latest information on brood stock management, production of monosex tilapia, seed production, and larval rearing under different culture systems - Highlights the most common infectious and non-infectious diseases affecting farmed tilapia, with a full description of disease symptoms and treatment measures - Provides an in-depth exploration of tilapia economics, trade and marketing

Integrated farming in Asia is either considered an eco-friendly good that should be preserved for environmental reasons or a poor practice that will soon be superseded by industrial aquaculture. This report finds that most livestock-fish integration is sound business conducted by entrepreneurs accessing urban markets where the price of fish is relatively low. It can be used as part of a strategy to reduce environmental impacts of intensive livestock production and to produce low-cost food. Farmers have proved adept at both developing their systems to meet their own needs and diversifying the role of ponds, fish and livestock within their complex livelihoods.

Learn to maximize tilapia production in different areas around the world Tilapia is the second-most cultured fish species in the world, and its production is increasing each year. However, for several reasons profit margins remain slim. Tilapia: Biology, Culture, and Nutrition presents respected international experts detailing every aspect of tilapia production around the world. Biology, breeding and larval rearing, farming techniques, feeding issues, post-harvest technology, and industry economics are clearly presented. This concise yet extensive reference provides the latest research and practical information to efficiently and economically maximize production in diverse locales, conditions, and climates. Tilapia: Biology, Culture, and Nutrition comprehensively explores all types of tilapia with a detailed biologic description of the fish that takes readers from egg through harvesting. The book authoritatively discusses production issues such as feed nutrition, temperature, water quality, parasites, and disease control to guide readers on how to best encourage fast, efficient growth. Economic and marketing information are examined, including industry data and projections by country. Each chapter approaches a specific facet of tilapia and provides the most up-to-date research available in that area. This resource gives the most current, detailed information needed for effective tilapia farming in one compact economical volume. Extensively referenced with an abundance of clear, helpful tables, photographs, and figures. Tilapia: Biology, Culture, and Nutrition discusses in detail: complete biology, including sex ratios, optimum temperatures for growth and spawning, water quality parameters, and disease tolerance industry predictions hormonal control of growth genetic improvement sex determination, manipulation, and control seed production culture practices earthen and lined pond production culture in flowing water cage culture feed formulation and processing, and feeding management soil, water, and effluent quality saline tolerance levels with optimum rate of acclimation to seawater polyculture of tilapia with shrimp bottom soil conditions nutrient requirements with non-nutrient components parasites and diseases Tilapia: Biology, Culture, and Nutrition is essential reading for aquaculturists, nutritionists, geneticists, hatchery managers, feed formulators, feed mill operators, extension specialists, tilapia growers, fish farmers/producers, educators, disease specialists, aquaculture veterinarians, policy makers, educators, and students.
