The efficient and profitable production of fish, crustaceans, and other aquatic organisms in aquaculture depends on a suitable environment in which they can reproduce and grow. Because those organisms live in water, the major environ mental concern within the culture system is water quality. Water supplies for aquaculture systems may naturally be oflow quality or polluted by human activity, but in most instances, the primary reason for water quality impairment is the culture activity itself. Manures, fertilizers, and feeds applied to ponds to enhance production only can be partially converted to animal biomass. Thus, at moderate and high production levels, the inputs of nutrients and organic matter to culture units may exceed the assimilative capacity of the ecosystems. The result is deteriorating water quality which stresses the culture species, and stress leads to poor growth, greater incidence of disease, increased mortality, and low produc tion. Effluents from aquaculture systems can cause pollution of receiving waters, and pollution entering ponds in source water or chemicals added to ponds for management purposes can contaminate aquacultural products. Thus, water quality in aquaculture extends into the arenas of environmental protection and food quality and safety. A considerable body of literature on water quality management in aquaculture has been accumulated over the past 50 years. The first attempt to compile this information was a small book entitled Water Quality in Warmwater Fish Ponds (Boyd I 979a).

Aquaculture pond managers measure water-quality variables and attempt to maintain them within optimal ranges for shrimp and fish, but surprisingly little attention is paid to pond soil condition. Soil-water interactions can strongly impact water quality, and soil factors should be considered in aquaculture pond management. The importance of soils in pond management will be illustrated with an example from pond fertilization and another from aeration. Pond fertilization may not produce phytoplankton blooms in acidic ponds. Total alkalinity is too low to provide adequate carbon dioxide for photosynthesis, and acidic soils adsorb phosphate added in fertilizer before phytoplankton can use it. Agricultural lime stone application can raise total alkalinity and neutralize soil acidity. The amount of limestone necessary to cause these changes in a pond depends on the base unsaturation and exchange acidity of the bottom soil. Two ponds with the same total alkalinity and soil pH may require vastly different quantities of limestone because they differ in exchange acidity. Aeration enhances dissolved oxygen concentrations in pond water and permits greater feed inputs to enhance fish or shrimp production. As feeding rates are raised, organic matter accumulates in pond soils. In ponds with very high feeding rates, aeration may supply enough dissolved oxygen in the water column for fish or shrimp, but it may be impossible to maintain aerobic conditions in the surface layers of pond soil. Toxic metabolites produced by microorganisms in anaerobic soils may enter the pond water and harm fish or shrimp.

The book describe the fundamental aspects water resources and water quality management, and environmental problems related to acquaculture in the Coastal related to aquaculture in the coastal areas. It addresses to the surface and ground water resources and their characteristics, in general and inherent in the coastal water environment, and describes the coastal environment with ecological divisions and coastal regulation Zones. Water resource use is highlighted mainly in coastal fisheries and aquaculture, and also in multiple uses for agriculture, forestry and waste disposal. Impacts of resource use on the coastal environment with potential and specific cases have been discussed. The book focuses on water quality aspects with the basic management issues such as physico-chemical, biophysical and biological parmeters and their interactions on the dynamics of the systems in a water body. On water quality management included are the topics under pond water treatment for control and management of aquatic environment for culture practices, and on farm effluent treatment for reduction of environmental impact in the surrounding water bodies. Related numerical problems have been given as examples in most of the chapters, as well as few sample questions for students work. The content of the book extends our theoretical understanding of water resource and water quality management, and also provides how-to or practical advice for professionals in the aquaculture industry.

In 1979, several graduate students in the Department of Fisheries and Allied Aquacultures at Auburn University met with one of the authors (CEB) and asked him to teach a new course on water supply for aqua culture. They felt that information on climatology, hydrology, water distribution systems, pumps, and wells would be valuable to them. Most of these students were planning to work in commercial aquaculture in the United States or abroad, and they thought that such a cdurse would better prepare them to plan aquaculture projects and to communicate with engineers, contractors, and other specialists who often become involved in the planning and construction phases of aquaculture en deavors. The course was developed, and after a few years it was decided that more effective presentation of some of the material could be made by an engineer. The other author (KHY) accepted the challenge, and three courses on the water supply aspects of aquaculture are now offered at Auburn University. A course providing background in hydrology is followed by courses on selected topics from water supply engineering. Most graduate programs in aquaculture at other universities will even tually include similar coursework, because students need a formal intro duction to this important, yet somewhat neglected, part of aquaculture. We have written this book to serve as a text for a course in water supply for aquaculture or for individual study. The book is divided into is concerned two parts.

Examine the world's leading aquaculture producers! Sustainable Aquaculture: Global Perspectives is a one-of-a-kind primer on the world's leading sources of aquatic production, presenting expert commentary that includes the latest advancements, developments, and research findings. The book examines essential elements of aquaculture (water quality, nutrition, genetics, culture methods) and addresses problems such as over-fishing, coastal and wetland destruction, and habitat and environmental degradation. Sustainable Aquaculture: Global Perspectives addresses policy measures that are essential for the long-term sustainability of the world's fisheries—and the long-term employment of those who rely on the aquaculture industry for their livelihood. As the world's population increases at an alarming rate, the question of how to ensure global food security is one of extreme importance. But the world's total yield is below expectations and the book examines the reasons why: the under-utilization of natural resources, the lack of adoption of modern scientific methods, the lack of standardized, proven pond fertilization protocols; long-term inbreeding and the loss of genetic variability due to genetic drift. Sustainable Aquaculture: Global Perspectives also addresses: freshwater pearl culture breeding programs pond fertilization regimes fish diseases in tropical climates indoor recirculating culture systems water quality management for shrimp farming and much more! With much of its information available in one place for the first time, Sustainable Aquaculture: Global Perspectives is invaluable as a textbook for introductory aquaculture courses and is an essential resource for professionals and researchers.
