Available in PDF, EPUB and Kindle. Book excerpt: Biological Monitoring of Marine Pollutants presents the proceedings of a symposium on ""Pollution and Physiology of Marine Organisms"" held in Milford, Connecticut, on November 7-9, 1980. It looks at the physiological effects of pollutants, such as synthetic organic compounds, petroleum hydrocarbons, and heavy metals, on marine organisms ranging from fishes and shrimps to barnacles, crabs, mussels, polychaetes, and microalgae. Comprised of four sections encompassing 22 chapters, this volume begins with an overview of the effects of synthetic organics, such as pesticides on marine organisms like the mysid shrimps Mysidopsis bahia. It proceeds with a discussion of the toxic effects of several chlorophenols on the grass shrimp, Palaemonetes pugio; how heavy metals, including silver, copper, cadmium, zinc, and mercury, affect species such as the polychaete Neanthes virens and the caridean shrimp Palaemonetes pugio; monitoring of water quality based on the biochemical and physiological responses of marine organisms to pollutants; and the effects of monocyclic aromatic hydrocarbons on fishes from an ecological standpoint. Marine scientists, ecologists, and students will find this book extremely useful.

Download or read book Upstream written by Committee on Protection and Management of Pacific Northwest Anadromous Salmonids and published by National Academies Press. This book was released on 1996-07-31 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of salmon to the Pacific Northwest--economic, recreational, symbolic--is enormous. Generations ago, salmon were abundant from central California through Idaho, Oregon, and Washington to British Columbia and Alaska. Now they have disappeared from about 40 percent of their historical range. The decline in salmon numbers has been lamented for at least 100 years, but the issue has become more widespread and acute recently. The Endangered Species Act has been invoked, federal laws have been passed, and lawsuits have been filed. More than $1 billion has been spent to improve salmon runs--and still the populations decline. In this new volume a committee with diverse expertise explores the complications and conflicts surrounding the salmon problem--starting with available data on the status of salmon populations and an illustrative case study from Washington state's Willapa Bay. The book offers specific recommendations for salmon rehabilitation that take into account the key role played by genetic variability in salmon survival and the urgent need for habitat protection and management of fishing. The committee presents a comprehensive discussion of the salmon problem, with a wealth of informative graphs and charts and the right amount of historical perspective to clarify today's issues, including Salmon biology and geography--their life's journey from fresh waters to the sea and back again to spawn, and their interaction with ecosystems along the way. The impacts of human activities--grazing, damming, timber, agriculture, and population and economic growth. Included is a case study of Washington state's Elwha River dam removal project. Values, attitudes, and the conflicting desires for short-term economic gain and long-term environmental health. The committee traces the roots of the salmon problem to the extractive philosophy characterizing management of land and water in the West. The impact of hatcheries, which were introduced to build fish stocks but which have actually harmed the genetic variability that wild stocks need to survive. This book offers something for everyone with an interest in the salmon issue--policymakers and regulators in the United States and Canada; environmental scientists; environmental advocates; natural resource managers; commercial, tribal, and recreational fishers; and concerned residents of the Pacific Northwest.

Download or read book The Development of Fishery Compartments and Population Rate Coefficients for Use in Reservoir Ecosystem Modeling written by George R. Leidy and published by . This book was released on 1977 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of analyses designed to develop model fishery compartments and associated fish population rate coefficients on a regional basis for use in reservoir ecosystem modeling are presented. Emphasis is directed toward development of regional rate coefficients for the United States corresponding to major geographical drainage areas. Fishery data will be incorporated in the reservoir ecosystem model currently being developed by personnel of the Environmental Effects Laboratory, U.S. Army Engineer Waterways Experiment Station. Known physical, chemical, and fishery conditions in 187 Corps of Engineers (CE) impoundments larger than 500 acres are described. Multivariable equations are presented that allow estimation of standing crop and sport fish harvest in CE reservoirs. Data were also reviewed and summarized on the ecological growth and assimilation efficiencies of fish, food consumption rates, respiration rates, temperature tolerances, half-saturation constants for growth, and chemical composition.

This book was released on 1993 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Up-to-date information, knowledge and research in progress in scientific fields related to natural production of juvenile Atlantic salmon and some other ecologically similar fluvial salmonids is contained in the 25 papers and 12 abstracts contained in this publication, which were prepared for an international symposium held in St. John's, Newfoundland. Studies relate to stream ecology, invertebrates and predators, habitat improvement, competitive effects, behaviour and dispersal, habitat and production of juvenile salmon, population dynamics and relationships of juvenile salmon estimates to smolt yields. A list of participants at the conference is also provided.
