The demand for high quality aquacultured products and an increasing concern for resource conservation has led individuals and large corporations to invest time and money in commercial scale recirculating production systems. However, there are relatively few reports of profitable recirculating production systems in operation. There is little doubt that most fish reared in ponds, floating net pens, or raceways can be produced in commercial scale recirculating systems.

The objective of this book is to provide basic information and analytical skills for the reader so that they may make the proper design or investment decisions concerning water reuse and recycle systems. The chapters of this book are sequenced to provide continuity to a basic approach that would be used in designing a water reuse or recycle system. The chapter authors contributing to this book have written extensively in the literature already on the particular subject being addressed in their chapter.

Considerable background information on the basic processes being presented is also given in each chapter to supplement the basic design information being provided. These chapters should provide the reader with essentially all the information required in order to design and manage a water reuse system.

The book is written for engineers and biologists working in the area of intensive fish culture. The text should also prove useful as a design manual for practising aquaculturists and as a resource of current "state-of-the-art" methodologies associated with water reuse systems.
