Sublethal and Chronic Effects of Pollutants on Freshwater Fish


Book Description

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.




Pollution and Fish Health in Tropical Ecosystems


Book Description

The tropical zone contains the highest diversity of fish species on the planet. Many of these species are being continuously exposed to pollutants that pose serious hazards to fish health thereby posing serious risks for entire fish populations. This book presents information about the different responses of fish to pollutants from the molecular le




Trends in Fisheries and Aquatic Animal Health


Book Description

Fish and other seafood have always been considered as an important part of human diet and have also long been recognized as a health-promoting food for human nutrition. However, managing aquatic food resources remains a challenge as the human population is expanding and overfishing poses a threat to fishing reserves in several areas. Aquaculture is the alternative solution for food production from the sea. According to the FAO, aquaculture is probably the fastest growing food-producing sector and can be a sustainable solution for fish production. In order to maximize marine food production and achieving sustainable management of the aquatic environment, knowledge about aspects of fisheries and aquatic animal health is very important. Trends in Fisheries and Aquatic Animal Health covers some basic and applied topics in fishery management and fish health with a focus on European regions. The textbook is a combination of reviews and research articles. Topics covered in the book include challenges in fishery management, environmental impacts on fisheries, fish health (pharmacology, histopathology, stress response), telemetry techniques in fisheries research, and specific case studies of regional marine species in localized fisheries. This textbook is a useful resource for graduates and professionals involved in advanced training courses for aquaculture and fishery management.




Endocrine Disruption in Fish


Book Description

The last half-century has shown a dramatic increase in the standard of living of millions of people in Europe, North America and many parts of the Third World. This has, in many ways been brought about by scientific and technical developments which were initiated in the 1940s and 1950s. Promises were then made that nuclear energy would provide electricity so cheap that it would not need metering, pesticides would end malnutrition throughout the world and plastics and other synthetic chemicals would revolutionise our manufacturing industry and our way of life. Whilst some of these promises have been fulfilled, the problems of long-term health risks to humans and wildlife arising from the use, production and disposal of these products were either unknown or deliberately understated. Nuclear power is rendered economically unviable when the real cost of decommissioning and storage of waste for several millenia is included, and the effects on health of both humans and wildlife of early pest eradication programmes with organochlorine pesticides were well documented in Rachel Carson's "Silent Spring". Evidence of the effects of aerosols and refrigerants on depletion of the ozone layer has led to restriction on the use of CFCs, and there is now increasing evidence of climate change resulting from our profligate use of fossil fuels.




Report of the Eighteenth Session of the European Inland Fisheries Advisory Commission, Rome, 17-25 May 1994


Book Description

EIFAC reviewed in depth the status and future direction of the inland fisheries and aquaculture sectors of Europe. The session reviewed EIFAC's activities since 1992 in the fields of fishery biology and management, fish culture and diseases and water pollution control.




Water Qual Freshwater Fish


Book Description

"This timely volume brings together recent critical reviews on water quality requirements for freshwater fish commissioned by the European Inland Fisheries Advisory Commission, an agency of the United Nations Food and Agriculture Organisation. It provides a unique and authoritative source of critically evaluated water quality data concerning the effects of chromium, nickel, aluminium and nitrite on freshwater fish and includes an assessment of the toxicity of mixtures. The reports presented in this volume cover all stages of the life cycle and relevant trophic levels, including aquatic invertebrates and plants and potential bioaccumulation through the food chain. An extensive bibliography is provided for each chapter as well as a glossary of terms and list of fish species mentioned in the text. This compilation of papers is the definitive reference volume for chemists, biologists, ecologists and toxicologists as well as for water resource managers concerned with management and control of pollution in fresh waters."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Oil in the Sea III


Book Description

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.
