Download or read book Joint FAO IOC IAEA technical guidance for the implementation of early warning systems for harmful algal blooms written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2023-03-16 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Globally, there are 3 400 to 4 000 described species of marine microalgae but only 1 to 2 percent are considered to be harmful. Harmful algal blooms (HABs) have significant impacts on food safety and security through contamination or mass mortalities of aquatic organisms. The impacts and mass mortalities of marine species caused by harmful algae are not new and have been recorded for decades. However, there is growing concern that these events will increase due to accelerating global warming, climate change and anthropogenic activities. Indeed, if not properly controlled, aquatic products contaminated with HAB biotoxins are responsible for potentially deadly foodborne diseases and when rapidly growing, HAB consequences include reduced dissolved oxygen in the ocean, dead zones, and mass mortalities of aquatic organisms. Improving HAB forecasting is an opportunity to develop early warning systems for HAB events such as food contamination, mass mortalities, or foodborne diseases. Surveillance systems have been developed to monitor HABs in many countries; however, the lead-time or the type of data (i.e. identification at the species-level, determination of toxicity) may not be sufficient to take effective action for food safety management measures or other reasons, such as transfer of aquaculture products to other areas. Having early warning systems could help mitigate the impact of HABs and reduce the occurrence of HAB events. The Joint FAO-IOC-IAEA technical guidance for the implementation of early warning systems (EWS) for HABs will guide competent authorities and relevant institutions involved in consumer protection or environmental monitoring to implement early warning systems for HABs present in their areas (marine and brackish waters), specifically those affecting food safety or food security (benthic HABs, fish-killing HABs, pelagic toxic HABs, and cyanobacteria HABs). The guidance provides a roadmap for stakeholders on how to improve or implement an EWS for HABs and biotoxins, where appropriate. It is important to note that not all countries and institutions can implement the same level of EWS for HABs, and this guidance is intended mainly for those who seek to broaden existing early warning systems, or who are just beginning to consider putting a system in place.

Download or read book Pathobiology of Marine and Estuarine Organisms written by John A. Couch and published by CRC Press. This book was released on 2021-04-14 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pathobiology of Marine and Estuarine Organisms is a comprehensive, up-to-date review of aquatic animal pathobiology covering infectious and non-infectious diseases of vertebrates such as marine mammals and fishes, in addition to diseases of invertebrates such as crustacea, mollusks, and lower phyla. The book provides critical information on viral, fungal, bacterial, parasitic, and neoplastic diseases of fish and invertebrates. Written by top-notch experts in the field, Pathobiology of Marine and Estuarine Organisms emphasizes pollution-associated diseases and includes an important review on the effects of pollution on marine mammals. The book will be a welcome addition to the libraries of aquatic and marine biologists, aquatic toxicologists, fisheries biologists, aquaculturalists, fish and invertebrate pathologists, and aquatic animal parasitologists.

Download or read book Manual on Harmful Marine Microalgae written by Henrik O. Enevoldsen and published by UNESCO. This book was released on 2003 with total page 808 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a source book of protocols for studying, monitoring and managing harmful marine microalgae. Proliferation of microalgae in marine, brackish or fresh waters can cause massive fish kills, contaminate seafood with toxins and alter ecosystems in ways humans perceive as harmful. About 300 species of microalgae are reported to form mass occurrences, so-called 'blooms', and nearly one-fourth of these species are known to produce toxins.This manual covers the fields of harmful algal sampling, identification, culturing, toxin analysis, toxicology and management.

Download or read book Pond Aquaculture Water Quality Management written by Claude E. Boyd and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: The efficient and profitable production of fish, crustaceans, and other aquatic organisms in aquaculture depends on a suitable environment in which they can reproduce and grow. Because those organisms live in water, the major environ mental concern within the culture system is water quality. Water supplies for aquaculture systems may naturally be oflow quality or polluted by human activity, but in most instances, the primary reason for water quality impairment is the culture activity itself. Manures, fertilizers, and feeds applied to ponds to enhance production only can be partially converted to animal biomass. Thus, at moderate and high production levels, the inputs of nutrients and organic matter to culture units may exceed the assimilative capacity of the ecosystems. The result is deteriorating water quality which stresses the culture species, and stress leads to poor growth, greater incidence of disease, increased mortality, and low produc tion. Effluents from aquaculture systems can cause pollution of receiving waters, and pollution entering ponds in source water or chemicals added to ponds for management purposes can contaminate aquacultural products. Thus, water quality in aquaculture extends into the arenas of environmental protection and food quality and safety. A considerable body of literature on water quality management in aquaculture has been accumulated over the past 50 years. The first attempt to compile this information was a small book entitled Water Quality in Warmwater Fish Ponds (Boyd I 979a).
