"Aquaculture Pond Fertilization: Impacts of Nutrient Input on Production is a current, practical reference on the nutrient input techniques and strategies used to maximize production in freshwater pond culture systems. All fish raised in ponds require fertilizers to be added during certain developmental stages that differ from species to species. Pond culture systems are used across a wide variety of freshwater fish species and appropriate fertilization is an important component to raising robust, efficient fish. Fertilization regimens must factor in many variables ranging from location and water quality to species type, all of which can impact responses to fertilizer application. Aquaculture Pond Fertilization provides the reader with practical information on nutrient management and application from leading researchers in the field. Species specific chapters provide real world examples of fertilization strategies for such key species as catfish, bass, tilapia, perch, carp, sport fish, and ornamentals"--

As a group, carp provide 4 million metric tonnes of fish annually - over a quarter of all fish culture worldwide. For the first time, a book is available in English that concentrates solely on the carp as an economic rather than an ornamental fish with a panel of international experts producing a comprehensive, practical volume about carp production and management. Starting with a brief look at the biology of cyprinids, the book then discusses the methods and management of carp farming, from water quality to the economics of fish production in ponds. Novel methods to improve stock, including genetic engineering, are covered and case studies give added value to the text. As carp farming turns from traditional to intensive methods, farmers, researchers and technicians in industry will welcome this benchmark volume, which also is a valuable reference book for graduate and postgraduate students and lecturers in aquaculture.

The first comprehensive monograph on periphyton, this book contains contributions by scientists fromaround the globe. Multi-disciplinary in nature, it covers both basic and applied aspects of periphyton,and is applicable worldwide in natural, extensive and intensive managed systems.Periphyton, as described in this book, refers to the entire complex of attached aquatic biota on submergedsubstrates, including associated non-attached organisms and detritus. Thus the periphyton communitycomprises bacteria, fungi, protozoa, algae, zooplankton and other invertebrates. Periphyton is importantfor various reasons: as a major contributor to carbon fixation and nutrient cycling in aquatic ecosystems;as an important source of food in aquatic systems; as an indicator of environmental change. It can alsobe managed to improve water quality in lakes and reservoirs; it can greatly increase aquaculture production;it can be used in waste water treatment.The book provides an international review of periphyton ecology, exploitation and management. Theecology part focuses on periphyton structure and function in natural systems. The exploitation part coversits nutritive qualities and utilization by organisms, particularly in aquaculture. The final part considersthe use of periphyton for increasing aquatic production and its effects on water quality and animal healthin culture systems. This book will help scientists and entrepreneurs further understand the ecology andproduction of aquatic systems and venture into new and promising areas.
