Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The culmination of over a decade's worth of research by the Pond Dynamics/Aquaculture Collaborative Research Support Program (CRSP), Dynamics of Pond Aquaculture not only explains the physical, chemical, and biological processes that interact in pond culture systems, but also presents real-world research findings and considers the people who depend on these systems. This book uses data from CRSP field research sites in East Africa, Southeast Asia, Central America, and North America to present a complete picture of the pond system and the environment in which it exists. A thorough study of the principles and practices of aquaculture, the book reflects the state of the art in pond aquaculture and incorporates recent advances that have changed the science in the last decade or so. It provides a thorough review of the many methods, techniques, and ideas that comprise this complex and fascinating area of study.

Available in PDF, EPUB and Kindle. Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: Aquaculture technology has been evolving rapidly over the last two decades, led by an increasingly skilled cadre of researchers in developing countries. Rather than copying, or adapting work done in industrialized countries to their situations, these scientists are moving aquaculture research out of the box to explore species and production systems relevant to their natural resources, economies and social institutions. Studies from India, Latin America, the Middle East and Africa are highlighted in this collection of papers, covering the entire gamut of aquaculture science from comparison of tilapia breeds, novel feed ingredients for indigenous species, improving disease resistance, water-use efficiency, traditional farming systems, spatial planning and economics. More than a how-to book, this volume introduces the researchers and institutions leading the development of aquaculture as it expands into new frontiers. This book was based on a special issue of the Journal of Applied Aquaculture.

Book excerpt: "Throughout the last century, specialisation and intensification were buzz words for farmers in the Western world. However, this approach has not resulted in sustainable development as evidenced by the fact that scientists now need to create technologies to reduce negative impacts. In this book we demonstrate that an alternative exists. Case studies from Bangladesh, Thailand, and Vietnam show that integration and diversification increase both farm productivity and farmers’ incomes. By adopting a participatory approach, farmers and scientists identified a range of technologies that strengthen the positive impacts of integrated aquaculture-agriculture systems for the environment. This book is a collection of refereed papers on a controversial subject in agricultural development. Arguing that sustainability of fish culture in ponds needs a new paradigm - feed the pond to grow fish - two chapters focus on nutrient cycling in such systems. Another chapter makes the case for breeding Nile tilapia for resource poor farmers and presents practical options to avoid the pitfalls that arise from natural tilapia mating in low-input ponds. The book contains chapters on livelihood and development aspects and ends with a general discussion completing the picture of the integrated aquaculture-agriculture systems. Overall it composes a review which addresses one of the key issues of the new century: how to sustainably produce food without compromising environmental integrity."
