This new textbook provides an accessible introduction to sustainable aquaculture through its relationship with three key pillars: the environment, the economy, and society.As the demand for seafood keeps increasing, aquaculture is considered one of the most promising and sustainable ways to satisfy this demand with nutritious and high-quality food. It is important to understand, therefore, the wider role and impact aquaculture has on the environment, the economy, and society. The book begins by providing a foundational introduction to aquaculture and sustainability, discussing the complex and interdependent relationship that exists between the two. The core text of the book is divided into four parts which focus on the environment, economics, social impacts, and governance and technologies. Chapters examine key issues surrounding climate change, food security, new technologies, bioeconomics and risk analysis, international cooperation, employment, and animal welfare, with the book concluding with a chapter examining the future directions and challenges for the aquaculture industry. The book draws on global case studies and each chapter is accompanied by recommended reading and chapter review questions to support student learning.This book will serve as an essential guide for students of aquaculture, fisheries management, and sustainable food, as well as practitioners and policymakers engaged in sustainable fishery development.

In the marine environment, single-celled, microscopic, plant-like organisms naturally occur in the well-lit surface layer of any body of water. These organisms, referred to as phytoplankton or microalgae, form the base of the food web upon which nearly all other marine organisms depend. Algal bloom is a rapid increase in or accumulation of the population of about 300 species of algae due to excess nutrients (eutrophication), and is of major global interest as it causes reduction in species diversity, abrupt changes in water quality, and discoloration of the water (green, yellow, brown or red) depending on the species of algae and the type of pigments they contain. Dying blooms can also be an environmental concern as when the cells sink and decay, bacteria break down the organic material, which in turn strips oxygen from the water. This microbial oxygen demand at times leads to very low oxygen levels in the bottom waters, harming aquatic life. Documentation of this sporadic high abundance of algae, together with the significant species richness of the diatoms, requires comprehensive studies in the Sundarban coastal environment, which is facing severe degradation due to natural & anthropogenic stressors. In addition, a better understanding of the effects of algal blooms on seafood quality, the complex biological, chemical and physical interactions and subsequent effects on trophodynamics is needed to develop strategies for effective coastal zone management. The book discusses the occurrence of harmful algal blooms (HABs) caused by the dinoflagellates of the genus Alexandrium and Karenia, or diatoms of the genus Pseudo-nitzschia, which have large and varied impacts on marine ecosystems (such as large-scale marine mortality events that have been associated with various types of shellfish poisonings) depending on the species involved, the environment where they are found, and the mechanism by which they exert negative effects. HABs represent a major environmental problem in all regions of the U.S., and their occurrence is on the rise due to increased nutrient pollution. HABs have severe impacts on human health, aquatic ecosystems, and the economy. Such blooms, known colloquially as red tides due to their red or brown hues, are increasing in frequency and magnitude worldwide as a result of changes in oceanic climate, increased coastal eutrophication and enhanced long-distance dispersal in ballast water. As such, the book offers an in-depth account of the complex biological, chemical and physical interactions of the algal blooms (both innocuous and harmful ones). It also discusses the highly topical issue of the impact of global climate change on the frequency and severity of HABs in the context of alterations in temperature, stratification, light and ocean acidification.Focusing on both basic and applied limnology, this book is a reliable and up-to-date referenceresource for students, teachers and researchers engaged in the field of coastal research/management at regional and global scales.

Intermittent Rivers and Ephemeral Streams: Ecology and Management takes an internationally broad approach, seeking to compare and contrast findings across multiple continents, climates, flow regimes, and land uses to provide a complete and integrated perspective on the ecology of these ecosystems.

In a readable and technically accurate style, the book utilizes logically framed chapters authored by experts in the field, allowing managers and policymakers to readily grasp ecological concepts and their application to specific situations. - Provides up-to-date reviews of research findings and management strategies using international examples - Explores themes and parallels across diverse sub-disciplines in ecology and water resource management utilizing a multidisciplinary and integrative approach - Reveals the relevance of this scientific understanding to managers and policymakers

This volume represents the proceedings of an international symposium on sample preparation, held at the University of Surrey, and jointly organised by the Chromatographic Society and the Robens Institute. The Chromatographic Society is the only international organisation devoted to the promotion of, and the exchange of information on, all aspects of chromatography and related techniques. With the introduction of gas chromatography in 1952, the Hydrocarbon Chemistry Panel of the Hydrocarbon Research Group of the Institute of Petroleum, recognising the potential of this new technique, set up a Committee under Dr S.F. Birch to organise a symposium on'Vapor Phase Chromatography'which was held in London in June 1956. Almost 400 delegates attended this meeting and success exceeded all expectation. It was to afford discussion of immediately apparent that there was a need for an organised forum development and application of the method and, by the end of the year, the Gas Chromatog­ raphy Discussion Group had been formed under the Chairmanship of Dr A.T. James with D.H. Desty as Secretary. Membership of this Group was originally by invitation only, but in deference to popular demand, the Group was opened to all willing to pay the modest sub­ scription of one guinea and in 1957 A.J.P. Martin, Nobel Laureate, was elected inaugural Chairman of the newly-expanded Discussion Group.

This volume contains the lectures and seminars given at the NATO Advanced Study Institute on “Sensor Systems for Biological Threads: The Algal Toxins Case”, held in Pisa, Italy in October, 2007. The Institute was sponsored and funded by the Scientific Affairs Division of NATO. It is my pleasant duty to thank this institution. This ASI offered updated information on how far the research on algal toxins has gone in the exploration of structures, biosynthesis and regulation of toxins, and the development of technology for bio-monitoring these c- pounds. Algae can form heavy growths in ponds, lakes, reservoirs and sl- moving rivers throughout the world; algae can house toxins which are - ually released into water when the cells rupture or die. Hundreds of toxins have been identified so far. Detection methods, including rapid screening, have been developed to help us learning more about them, especially to find out which toxins are a real threat for people and what conditions encourage their production and accumulation. Early detection of algal toxins is an - portant aspect for public safety and natural environment, and significant efforts are underway to develop effective and reliable tools that can be used for this purpose.
