This book was released on 2000 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Blooms of toxic or harmful microalgae, commonly called "red tides," represent a significant - and expanding threat to human health and fisheries resources throughout the United States and the world. These phenomena take many forms, ranging from massive accumulations of cells that discolor the water to dilute, inconspicuous, but highly toxic populations. Ecological, aesthetic, and public health impacts include: mass mortalities of wild and farmed fish and shellfish; human intoxication and death from the consumption of contaminated shellfish or fish; alterations of marine food webs through adverse effects on larvae and other life history stages of commercial fish species; the noxious smell and appearance of algae accumulated in nearshore waters or deposited on beaches; and mass mortalities of marine mammals, seabirds, and other animals. Many harmful algal blooms (HABs) have significant economic impacts. Shellfish closures, wild or farmed fish mortalities, and scared consumers who avoid seafood are well-recognized impacts of major HABs. While adverse health effects and lost sales of fish and shellfish products are direct costs, constrained development or investment decisions in coastal aquaculture due to the threat from outbreaks of toxic algae are examples of poorly understood or poorly quantified indirect or hidden costs. Lost marine recreational opportunities also are a significant cost of harmful algal bloom incidents. HABs have increased steadily in both species complexity and geographical extent over the last several decades. In turn, the range of harmful effects and the magnitude of economic costs have also widened. This report provides the first comprehensive estimate of the economic impacts of HABs in the United States, focusing on both direct and indirect costs.

Download or read book Global Ecology and Oceanography of Harmful Algal Blooms written by Patricia M. Glibert and published by Springer. This book was released on 2018-04-26 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Harmful algal blooms (HABs) - blooms that cause fish kills, contaminate seafood with toxins, or cause human or ecological health impacts and harm to local economies - are occurring more often, in more places and lasting longer than in past decades. This expansion is primarily the result of human activities, through increased nutrient inputs and various aspects of climate change. The Global Ecology and Oceanography of Harmful Algal Blooms (GEOHAB) programme promoted international collaboration to understand HAB population dynamics in various oceanographic regimes and to improve the prediction of HABs. This volume introduces readers to the overarching framework of the GEOHAB programme, factors contributing to the global expansion of harmful algal blooms, the complexities of HABs in different habitats, and the forward-looking issues to be tackled by the next generation of GEOHAB, GlobalHAB. The programme brought together an international team of contributing scientists and ecosystem managers, and its outcomes will greatly benefit the international research community.

Download or read book New Technologies in Aquaculture written by Gavin Burnell and published by Elsevier. This book was released on 2009-07-30 with total page 1226 pages. Available in PDF, EPUB and Kindle. Book excerpt: With wild stocks declining due to over-fishing, aquaculture will have a more significant role to play in meeting future demand for fresh fish. Developments in research continue to lead to improvements in aquaculture production systems, resulting in increased production efficiency, higher product quality for consumers and a more sustainable industry. New technologies in aquaculture reviews essential advances in these areas. Part one focuses on the genetic improvement of farmed species and control of reproduction, with chapters on genome-based technologies in aquaculture research, selective breeding and the production of single sex and sterile populations, among other topics. Parts two and three review key issues in health, diet and husbandry, such as the control of viral and parasitic diseases, diet and husbandry techniques to improve disease resistance, advances in diets for particular fish species and the impact of harmful algal bloom on shellfisheries aquaculture. Chapters in Parts three and four then examine the design of different aquaculture production systems, including offshore technologies, tank-based recirculating systems and ponds, and key environmental issues, such as the prediction and assessment of the impact of aquaculture. Concluding chapters focus on farming new species. With its well-known editors and distinguished international team of contributors, New technologies in aquaculture is an essential purchase for professionals and researchers in the aquaculture industry. Reviews recent advances in improvements in aquaculture production Focuses on the genetic improvement and reproduction of farmed species, including genome-based technologies Discusses key health issues, including advances in disease diagnosis, vaccine development and other emerging methods to control pathogens in aquaculture

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 Marine Algal Bloom Characteristics Causes and Climate Change Impacts written by Santosh Kumar Sarkar and published by Springer. This book was released on 2018-05-02 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 reference resource for students, teachers and researchers engaged in the field of coastal research/management at regional and global scales.
