Download or read book Sublethal and Chronic Effects of Pollutants on Freshwater Fish written by Rudolf Müller and published by Wiley-Blackwell. This book was released on 1994-01-01 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent years have seen much greater emphasis placed on the monitoring and measurement of sublethal aspects of pollution on fish. Tests and subsequent measurements have been made over the whole range of biological organisation – from the subcellular to changes at community structure level. Studies at the lower levels attract considerable scientific interest but, in many cases, it is still difficult to interpret the results of tests in terms of predicted harmful effects on individual fish. Conversely, it has been difficult to attribute the effects measured at higher levels to specific pollutants. This major new volume of immense scientific importance to fisheries managers, fish biologists, ecotoxicologists and those working in the area of fisheries and pollution, contains thirty–two papers presented at the Symposium hosted by the European Inland Fisheries Advisory Commission. Contributions come from an international team of distinguished experts and, together, the papers represent a detailed overview of work which is currently being undertaken in this area. Unlike many Symposia which simply report proceedings, this volume integrates the results of various areas of research and offers solid recommendations for future research and control.

Download or read book Toxic and Sublethal Effects of Insecticides Carbaryl on a Fresh Water Fish Barbus Stigma cyprinidae written by G. N. Subbiah and published by . This book was released on 1982 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effect of lethal and sublethal concentration of insecticide carbaryl on a fresh water fish, Barbus stigma was studied. A concentration of 25 ppm (25 mg/litre) proved to be fatal and causes 100% mortality. At 11.1 ppm concentration the mortality is 50% (LC50). At 7 ppm and below the insecticide is sublethal to the fish but results in degraded metabolism, viz: reduced rate of feeding, assimilation, conversion, growth and respiration. As an overall effect of the insecticide the nutritive value of the fish B. stigma is drastically reduced by 4 to 25%. [Authors abstract].

Download or read book Pesticide Residues in Coastal Tropical Ecosystems written by Milton D Taylor and published by CRC Press. This book was released on 2002-11-21 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: The coastal tropics comprise some of the most sensitive and yet the most understudied ecosystems in the world. Coastal plains and river valleys are also home to agriculture on a vast scale, and it is not surprising to find that streams and rivers receive the majority of agricultural runoff, carrying the residues of insecticides, fungicides and other pesticides into estuaries and coastal zones. There is a growing awareness of the urgent need to develop strategies to help productive, healthy and economically viable agriculture to coexist with natural resources. Pesticide Residues in Tropical Coastal Ecosystems brings together toxicology experts from around the world to assess pesticide burdens in many of the major food-producing tropical countries. It provides a unique set of case studies, chronicling pesticide usage and its ecotoxicological impact in coastal regions. A practical guide to recent research findings and applications, it is essential reading for environmental professionals, ecotoxicologists, marine chemists and agrochemists.

Download or read book Effects of Pollution on Fish written by Andrew J. Lawrence and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impact of pollution on fisheries and the potential health implications of eating contaminated fish are areas of considerable concern for the fishing and aquaculture communities, government bodies and the general public. Pollution, as well as over fishing, may well be contributory to recent serious declines in global fish stocks. Effects of Pollution on Fish brings together the work of many international experts each of whom have examined the literature on marine and freshwater fish and, where appropriate, invertebrates, to produce comprehensive chapters covering all major aspects of the impacts of pollution on fish and fisheries. The book describes these impacts in detail, from the molecular and sub-cellular level, through organism to population and community levels, and subsequently to socio-economic implications. The editors of this thorough and timely book have drawn together contributions encompassing molecular genetics, biochemistry, physiology, population and community biology, and fishery economics. As such, this important book will be of great use and interest to students and professionals studying and teaching in all those subject areas. Fish biologists, environmental scientists and ecotoxicologists, marine and freshwater ecologists, fisheries managers, aquaculture personnel and fish farmers, as well as fish veterinarians will all find much of great value within this book. Libraries in universities and research establishments concerned with these areas should all have copies of this book on their shelves.

Available in PDF, EPUB and Kindle. Book excerpt: Since the early 1970s, experts have recognized that petroleum pollutants were being discharged in marine waters worldwide, from oil spills, vessel operations, and land-based sources. Public attention to oil spills has forced improvements. Still, a considerable amount of oil is discharged yearly into sensitive coastal environments. Oil in the Sea provides the best available estimate of oil pollutant discharge into marine waters, including an evaluation of the methods for assessing petroleum load and a discussion about the concerns these loads represent. Featuring close-up looks at the Exxon Valdez spill and other notable events, the book identifies important research questions and makes recommendations for better analysis ofâ€"and more effective measures againstâ€"pollutant discharge. The book discusses: Inputâ€"where the discharges come from, including the role of two-stroke engines used on recreational craft. Behavior or fateâ€"how oil is affected by processes such as evaporation as it moves through the marine environment. Effectsâ€"what we know about the effects of petroleum hydrocarbons on marine organisms and ecosystems. Providing a needed update on a problem of international importance, this book will be of interest to energy policy makers, industry officials and managers, engineers and researchers, and advocates for the marine environment.
