Book Description
Quality seed, feed and fertilizer are known to decree target fish yield in any type of aquaculture system. Among these vital factors, the right type and input schedule of fertilizers have gathered much scientific concern. Obviously, phosphorus the major limiting nutrient of freshwater culture system has been studied in detail by various workers. However, there is brevity of information on the colossal loss of money encountered by the fisheries sector engrossed in freshwater culture due to the transformation of phosphatic fertilizers into non-recyclable apatite phosphorus. This book provides the first hand information on the utilization of sodium tripolyphosphate in hard water fish culture system for relegating the formation of apatite. The merit of such investigations lie in the fact that the development of a proper phosphatic fertilization schedule for hard water will hold good for brackishwater fish pond also. The results of the present investigation affirm the fact that apatite occurs as the second major constituent of total sedimentary phosphorus. Though the chemical reactions leading to the formation of apatite in aquatic ecosystems remain as a riddle, many of the field trials fortify the operation of the phenomenon of apatite formation in aquaculture system. The present study focuses its prime attention over this crucial reality and advocates the benefits of utilizing sodium tripolyphosphate as a phosphatic fertilizer in aquaculture system. The authors are convinced that intensive field trails in this regard would pave way for the most aspired blue revolution.

Book Description
Key features: Takes a quantitative approach to the science of aquaculture Covers the complete landscape of the scientific basis of fish culture Promotes problem solving and critical thinking Includes sample problems at the end of most chapters Guides the reader through the technical considerations of intensive aquaculture, including fish growth rates, hydraulic characteristics of fish rearing units, oxygen consumption rates in relation to oxygen solubility and fish tolerance of hypoxia, and water reconditioning by reaeration and ammonia filtration. Discusses the environmental effects of aquaculture Includes a chapter on hatchery effluent control to meet receiving water discharge criteria Aquaculture Technology: Flowing Water and Static Water Fish Culture is the first book to provide the skills to raise fish in both a flowing water and a static water aquaculture system with a pragmatic and quantitative approach. Following in the tradition of the author’s highly praised book, Flowing Water Fish Culture, this work will stand out as one that makes the reader understand the theory of each type of aquaculture system; it will teach the user "how to think" rather than "what to think" about these systems. The book presents the scientific basis for the controlled husbandry of fish, whether it be in a stream of water or a standing water pool. Part 1, Flowing Water Fish Culture, is a major revision of the author’s initial book and includes greatly expanded coverage of rearing unit design criteria, fish growth and the use of liquid oxygen, hatchery effluent control, and recirculating systems. Part 2, Static Water Fish Culture, presents the scientific basis of fish culture in standing water systems including nutrient and dissolved gas dynamics, pond ecology, effects of fertilization and supplemental feeding, water quality management and representative static water aquacultures. Aquaculture Technology conveys the science in a manner appropriate for use by university students and teachers and others involved in fish production and aquaculture research and development worldwide. It will enable the reader to adapt to changing technologies, markets, and environmental regulations as they occur.

Book Description
This volume provides state-of-the-art information on soil-water interactions in wastewater systems, characterization of wastewater, modes of treatment, safety of wastewater use, water conservation technologies involved in recycling of sewage in fish culture, biogeochemical cycling bacteria and nutrient dynamics, ecosystem resilient driven wastewater reclamation, bioremediation, aquaponics, ecological integrity, culture practices of fish farming, microbial food web phenomena, fish diseases, environmental economics of wastewater, environmental risk assessment, environmental law and regulations. Given its breadth of coverage, the book will be useful to researchers, teachers, students, administrators, planners, farmers and entrepreneurs interested in the profitable use of wastewater in the wastes-into-wealth framework of for the benefit of humanity, and in achieving the targets for sanitation and safe wastewater reuse by 2030, specified in the United Nations’ Sustainable Development Goals. Concerns are growing about the quality and quantity of fresh water, as severe crises are expected in the near future. Climate change has further worsened the strain on inland water resources, with its major impacts on ecosystems and human life. It is most urgent to protect and conserve inland water resources to maintain vital ecosystem functions. Despite the immense nutrient potentials of wastewater in terms of phosphorus, nitrogen and potassium and increasingly high rates of urbanization-based wastewater generation, wastewater has traditionally been overlooked as a resource. This produces a threefold loss – environmental degradation, monetary losses from fertilizers, and water. As a result, municipal wastewater offers a win-win strategy for water conservation and environmental protection, while also turning waste into wealth in the form of fish biomass and allied cash crops. Wastewater-fed aquaculture refers to a unique, integrated biosystem in which the wastes generated by the first system are used by the next subsystem. In wastewater-fed aquaculture biosystems, the organic wastes are recycled into fish biomass mediated through a complex microbial/autotrophic/heterotrophic food web mechanism.

Book Description
As aquaculture continues to grow at a rapid pace, understanding the engineering behind aquatic production facilities is of increasing importance for all those working in the industry. Aquaculture engineering requires knowledge of the many general aspects of engineering such as material technology, building design and construction, mechanical engineering, and environmental engineering. In this comprehensive book now in its second edition, author Odd-Ivar Lekang introduces these principles and demonstrates how such technical knowledge can be applied to aquaculture systems. Review of the first edition: 'Fish farmers and other personnel involved in the aquaculture industry, suppliers to the fish farming business and designers and manufacturers will find this book an invaluable resource. The book will be an important addition to the shelves of all libraries in universities and research institutions where aquaculture, agriculture and environmental sciences are studied and taught.' Aquaculture Europe 'A useful book that, hopefully, will inspire successors that focus more on warm water aquaculture and on large-scale mariculture such as tuna farming.' Cision

Book Description
Fish Nutrition aims to present the state of knowledge of basic and applied nutritional requirements of fishes. Most of the information found in this book involves salmonids, their nutrition, and metabolism of nutrients. This is in view of the fact that more research has been done and completed with this fish. Although applied fish nutrition is a very broad field, this book focuses on some of its aspects. These include the classes of nutrients and requirements for several types of fishes. This book comprises of 11 chapters. The first few chapters deal with the general nutrient requirements of fishes. Then, other chapters discuss calorie and energy as well as micro- and macronutrient needs and requirements. The following chapters deal with the non-nutrient components of the diet, or those that influence the characteristics of food products including texture, odor, flavor, and color. Other topics covered are enzymes and systems of intermediary metabolism (Chapter 6); feed formulation and evaluation (Chapter 7); and salmonid husbandry techniques (Chapter 9). Nutritional fish diseases are also discussed in this book. Some of these diseases include thyroid tumor, gill disease, anemia, lipoid liver degeneration, and visceral granuloma. In Chapter 11, the relationship of nutrition and pathology is given emphasis. This chapter also tackles the diet and general fish husbandry. This topic is very important, because an adequate diet for fish husbandry is the foundation of fish farming.
