A major concern among ecologists in and outside the ASEAN region is the degradation of the environment, and the overexploitation of freshwater and marine resources. There is as yet no indication that freshwater and marine resources are being managed on a sustainable basis, and loss of wetlands, whether freshwater swamps or mangrove swamps, is a major problem in the ASEAN region. Reclamation of mangrove swamps for aquaculture and agriculture seems to be a continuous activity here and the status of marine parks should also be examined in the light of recent resort development acitivities on small islands. This volume contains numerous recommendations for the promotion of ecological studies and regional cooperation in marine, freshwater ecology and conservation, with special emphasis on the common water masses like the Strait of Malacca, Gulf of Thailand and the South China Sea.

This book examines large-scale outbreaks of red tide along coastal areas, which is associated with fish and shellfish mass mortalities through poisoning. This book discusses the red tide phenomena throughout the world, including biological research results on taxonomy of cyst and vegetative cells of red tide organisms and ecological and physiological studies using ecological modeling.

The occurrence of marine and freshwater toxins is a rapidly evolving problem due to ever-changing circumstances. Expanding international commerce is forcing cargo ships into virgin territory, deforestation and pollution violate the natural ecological balance, and a changing climate holds unknown potential to alter current factors and trigger toxic blooms in new forms, at new rates, and in new places. Fortunately, with notable advances in analysis technology, the body of knowledge in the field is equally dynamic. In just six years since the first edition, toxins that warranted only line listings, including pfiestra, gambierol, and polycavernoside, are now worthy of entire chapters, requiring a new edition to encompass the expanding scope of the field. Emphasizes Human Response to New Toxins Gathering contributions from international experts, Seafood and Freshwater Toxins: Pharmacology, Physiology, and Detection, Second Edition provides an overview of the current state-of-knowledge from several perspectives. Incorporating toxicology, chemistry, ecology, and economics, the book covers the biological aspects of the bloom and the effects and actions of each toxin with emphasis on human response. This edition includes more information on detection and analysis, toxicological information on previously little known toxins, and food safety issues. Incorporating Pharmacological, Legal, and Economic Aspects, this book— Begins with general information on risk assessment and analytical techniques Cover several categories of toxins by function and biomechanism Considers potential pharmacological applications and the use of toxins as precursors to therapeutic drugs Highlights the legal and economic perspectives of toxic incidence in industrial activity and international regulation and monitoring programs Describes new toxins by their individual chemical structure, ecobiology, metabolism, detection methods, determination, pharmacology, and toxicology

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.

Shellfish are a very popular and nutritious food source worldwide and their consumption has risen dramatically. Because of their unique nature as compared to beef and poultry, shellfish have their own distinct aspects of harvest, processing and handling. Edited by leading authorities in the field, this collection of review papers discusses issues of current interest and outlines steps that can be taken by the shellfish industry to improve shellfish safety and eating quality.Opening chapters provide an overview of the key issues associated with microbial and biotoxin contamination. Parts two and three then address in more detail methods to improve molluscan shellfish and crustacean quality and safety. Chapters focus on detection of algal toxins, monitoring and mitigation of the effects of harmful algal blooms, metals and organic contaminants, biofouling, disease control and selective breeding. Part four reviews legislation, regulation, public confidence in shellfish and risk management. Chapters on post-harvest issues, such as depuration, storage and packaging complete the volume.With its distinguished editors and international team of experts, Shellfish safety and quality is an essential reference for those in the shellfish industry, managers, policymakers and academics in the field. - Reviews the latest research on significant hazards such as microbial and biotoxin contamination - Discusses effective management of shellfish safety and quality, including emerging methods - Examines improved packaging methods
