Download or read book Sustaining Marine Fisheries written by Committee on Ecosystem Management for Sustainable Marine Fisheries and published by National Academies Press. This book was released on 1999-03-05 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluctuations and declines in marine fish populations have caused growing concern among marine scientists, fisheries managers, commercial and recreational fishers, and the public. Sustaining Marine Fisheries explores the nature of marine ecosystems and the complex interacting factors that shape their productivity. The book documents the condition of marine fisheries today, highlighting species and geographic areas that are under particular stress. Challenges to achieving sustainability are discussed, and shortcomings of existing fisheries management and regulation are examined. The volume calls for fisheries management to adopt a broader ecosystem perspective that encompasses all relevant environmental and human influences. Sustaining Marine Fisheries offers new approaches to building workable fisheries management institutions, improving scientific data, and developing management tools. The book recommends ways to change current practices that encourage overexploitation of fish resources. It will be of special interest to marine policymakers and ecologists, fisheries regulators and managers, fisheries scientists and marine ecologists, fishers, and concerned individuals.

Download or read book Chesapeake Waters written by Steven Gebauer Davison and published by Cornell Maritime Press/Tidewater Publishers. This book was released on 1997 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although media reports suggest that there always has been public concern over the health of the Chesapeake Bay, this is a fairly recent phenomenon. For centuries people saw the bay as a bottomless sink for waste products--a natural decomposer with the ability to freshen itself with ocean inflows. Not until human health and livelihood seemed threatened did people begin to think seriously about management by such methods as treating sewage and limiting seafood harvests. Chesapeake Waters chronicles four centuries of public attitudes about the bay--and legislative responses to them--from 1607, the date of the first English settlement in Jamestown, Virginia, to the close of the twentieth century. In the last few decades, wide-reaching measures by federal and local governments have influenced how people use the bay: the U.S. Environmental Protection Agency completed a massive study of bay quality; the Chesapeake Bay Program was launched; the Critical Area Protection Act went into effect. The authors make sense of these complex programs, place them in historical context, and explain how they have improved the quality of bay waters. Chesapeake Waters is as much about the power of public perception as it is about efforts to oversee bay water quality. In a work rich with anecdotes and historical art and photos, the authors relate how human attitudes and ideas have shaped four hundred years of decisions about the Chesapeake Bay.

Download or read book Evolution of the Great Lakes Water Quality Agreement written by Lee Botts and published by Dave Dempsey Environmental. This book was released on 2005 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water quality concerns are not new to the Great Lakes. They emerged early in the 20th century, in 1909, and matured in 1972 and 1978. They remain a prominent part of today's conflicted politics and advancing industrial growth. The Great Lakes Water Quality Agreement, under the Boundary Waters Treaty of 1909, became a model to the world for environmental management across an international boundary. Evolution of the Great Lakes Water Quality Agreement recounts this historic binational relationship, an agreement intended to protect the fragile Great Lakes. One strength of the agreement is its flexibility, which includes a requirement for periodic review that allows modification as problems are solved, conditions change, or scientific research reveals new problems. The first progress was made in the 1970s in the area of eutrophication, the process by which lakes gradually age, which normally takes thousands of years to progress, but is accelerated by modern water pollution. The binational agreement led to the successful lowering of phosphorus levels that saved Lake Erie and prevented accelerated eutrophication in the rest of the Great Lakes ecosystem. Another major success at the time was the identification and lowering of the levels of toxic contaminants that cause major threats to human and wildlife health, from accumulating PCBs and other persistent organic pollutants

Phillips and published by Geological Survey (USGS). This book was released on 2007 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this report is to present a synthesis of the USGS Chesapeake Bay science related to the 2001-06 goals and provide implications for environmental management. The report provides USGS findings that address the science needs of the Chesapeake Bay Program (CBP) restoration goals and includes summaries of 1. land-use change; 2. water quality in the watershed, including nutrients, sediment, and contaminants; 3. long-term changes in climate and estuarine water quality; 4. estuary habitats, focusing on submerged aquatic vegetation (SAV) and tidal wetlands; and 5. factors affecting fish and waterbird populations.
