Fish Nutrition


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.




Energy Metabolism in Animals and Man


Book Description

Abstract: This book discusses the factors which affect the heat produced by animals and man and the ways in which the energy of the organic components of their diets are used to support growth and reproduction. The general thermodynamic principles are considered in addition to the physical principles related to heat loss by radiation, convection, conduction and evaporation of water. Major parts of the book deal with the minimal or basal production of heat, with the heat produced during muscular work and as a result of physiological reactions to the climatic environment. The test is intended for undergraduates and postgraduates who are studying energy metabolism in the context of zoology, agriculture, ecology, or medicine.




Nutrition of Pond Fishes


Book Description

This book reviews the subject of fish nutrition, one of the key aspects of aquacultural systems.




Utility Benchmarking and Regulation in Developing Countries


Book Description

Utility performance, especially in developing countries is still working toward the standard necessary to deliver best practice. Utility Benchmarking and Regulation in Developing Countries examines performance monitoring and regulation as a prominent efficiency enhancement tool and clarifies many of the unknowns regarding the design and approach surrounding the area of utility management. Principles and practices are linked in a way that is informative and accessible, highlighting the challenges facing those who are trying to improve performance in the water sector. Operational settings are complex and unpredictable in developing countries due to inadequate infrastructure planning and this book makes clear which systems work best in these situations. Utility Benchmarking and Regulation in Developing Countries discusses performance monitoring in the critical areas of utility management that achieve sustainable performance goals: Performance development planning Modes of performance monitoring Provocative approaches to incentives creation Monitoring through high incentive plans Customer relations monitoring Pro-poor oriented monitoring Careful use of partial performance indicators Proposed indicators for assessing governance incentives A case study on the National Water and Sewerage Corporation, Uganda is included in the book detailing the difficulties in discerning performance progress based on partial performance indicators. It underlines disparities in basing performance conclusions on partial performance indicators on one hand and aggregate analysis using modern benchmarking toolkits on the other. This is an excellent handbook for utility monitors or regulators whose primary duty is to oversee performance management. It is a valuable resource for decision-makers, analysts, and policy-makers and can be used in capacity-building programs (both in-house and in universities) around the world.




Water Management in Megacities


Book Description

Efficient and equitable water, wastewater and stormwater management for the megacities is becoming an increasingly complex task. The special issue will focus on water management in its totality for megacities, including their technical, social, economic, legal, institutional and environmental dimensions through a series of specially invited case studies from different megacities of the world. At present, around one out of two of the earth’s 6.3 billion people live in urban areas. Each year, the world population grows by around 80 millions. Practically all of this growth is urban, primarily due to migration. World’s urban population is expected to reach 5 billion by 2030, which is nearly 2/3rd more than in 2000, and would mean that 60% of world’s population will live in urban areas. The case studies analysed include some of the most interesting and challenging megacities of this planet, Dhaka, Istanbul, Jakarta, Johannesburg, México City, Riyadh and São Paulo. They assess different aspects of how water is intermingled in the overall development milleau. The special issue will considers the magnitudes, nature and extent of the present and future challenges and how these could be meet in socially acceptable and cost-effective ways. The contributors are all acknowledged water experts from different parts of the world. This book was previously published as a special issue of the International Journal of Water Resource s Development.




Urban Water Infrastructure


Book Description

URBAN WATER INFRASTRUCTURE NATO ADVANCED RESEARCH WORKSHOP SUMMARY 22-27 JUNE 1989 KYLE E SCHILLING P E Workshop Director The Workshop was based on the recognition that all NATO countries are concerned with similar water infrastructure issues. Present problems are aggravated by aging and neglected facilities, by inadequate financing and by water management institutions reflecting the needs of an earlier era. Service needs to be provided for expanding populations, at the same time that corrective measures must be taken for decaying older urban centers, resulting both from neglect and expiring service life. These needs exist within the framewode of other competing and conflicting uses for existing and yet to be developed water sources. The problems have generated some highly visible national debates over financing due to the large sums involved. Despite differences in the age of the North American, European and other societies, the technological ages of water supply and storm water systems are much the same and provide a common denominator in the worldwide trend to urbanization. Examination of approaches to urban water management also indicates that they are generally based on past experience and institutions created in a non-urban era. The physical, financial and institutional alternatives are consequently often out-of-step with current urban environment. Historically, the supply of adequate water and efficient storm water management have also been top priority items with water quality and other aspects of environmental protection assuming a lower priority after basic supply needs have been met.




Water-Wise Cities and Sustainable Water Systems


Book Description

Building water-wise cities is a pressing need nowadays in both developed and developing countries. This is mainly due to the limitation of the available water resources and aging infrastructure to meet the needs of adapting to social and environmental changes and for urban liveability. This is the first book to provide comprehensive insights into theoretical, systematic, and engineering aspects of water-wise cities with a broad coverage of global issues. The book aims to (1) provide a theoretical framework of water-wise cities and associated sustainable water systems including key concepts and principles, (2) provide a brand-new thinking on the design and management of sustainable urban water systems of various scales towards a paradigm shift under the resource and environmental constraints, and (3) provide a technological perspective with successful case studies of technology selection, integration, and optimization on the “fit-for-purpose” basis.




Water Communication


Book Description

Water Communication aims at setting a first general outlook at what communication on water means, who communicates and on what topics. Through different examples and based on different research and contributions, this book presents an original first overview of “water communication”. It sets its academic value as one distinct scientific domain and provides tips and practical tools to professionals. The book contributes to avoid mixing messages, targets and discourses when setting communication related to water issues. The book facilitates coordination within the water sector and its organizations as water is a wide field of applications where inadequate words and language understanding between its stakeholders is one of the main obstacles today. Water Communication provides and describes: a general outlook and retrospective of the history of the water sector in terms of communication the landscape of organizations communicating on water and classification of topics the differences between communication, information, mediation, raising awareness examples of communication campaigns on water Water Communication is a vital resource for communication managers, utility managers, policy makers involved in water management and students in water sciences and environment.
