Pond Aquaculture Water Quality Management provides the most complete, up-to-date account of water quality and its management in aquaculture ponds. It provides background information on the physical, chemical, and biological environment of pond aquaculture, and illustrates how the proper balance of these factors is the essential ingredient for successful production of fish and other aquatic animals. Management techniques for the control of water quality and productivity include liming, fertilization, mechanical aeration, water exchange, and the use of algicides and herbicides. The authors examine the effects of pollution on aquaculture and the validity of current criticisms by environmentalists. Pond Aquaculture Water Quality Management will be a great benefit to students, extension agents, policy-makers, government officials and the commercial 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.
