"The book describes the fundamental aspects water resources and water quality management, and environmental problems 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 parameters 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 student\'s 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."
