Water Quality
This volume is of great importance to humans and other living organisms. The study of water quality draws information from a variety of disciplines including chemistry, biology, mathematics, physics, engineering, and resource management. University training in water quality is often limited to specialized courses in engineering, ecology, and fisheries curricula. This book also offers a basic understanding of water quality to professionals who are not formally trained in the subject. The revised third edition updates and expands the discussion, and incorporates additional figures and illustrative problems. Improvements include a new chapter on basic chemistry, a more comprehensive chapter on hydrology, and an updated chapter on regulations and standards. Because it employs only first-year college-level chemistry and very basic physics, the book is well-suited as the foundation for a general introductory course in water quality. It is equally useful as a guide for self-study and an in-depth resource for general readers.
An Introduction to Water Quality Science
This book discusses the significance of water quality parameters in aquatic ecosystems, offering a concise and practical measurement methodology for early career researchers and post-graduate students in the fields of environmental science, oceanography, and aquatic science . The keys topics covered include aquatic sampling, basics of physicochemical properties and carbonate chemistry of aquatic science , the importance of nutrients in natural water bodies, biological productivity in aquatic ecosystems, aquatic pollution, and statistical analyses of different types of water science data. Several parameters such as microplastics, dimethylsulfoniopropionate and polychlorinated biphenyls have also been incorporated in the book for comprehensive coverage of the topic. The book is meant as a practical guide for beginners and young researchers using a clear writing style and practical examples, highlighting the significance of water science parameters and their measurement protocols in aquatic environments.
Pond Aquaculture Water Quality Management

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).
