Download or read book Achieving Nutrient and Sediment Reduction Goals in the Chesapeake Bay written by National Research Council and published by National Academies Press. This book was released on 2011-09-26 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chesapeake Bay is North America's largest and most biologically diverse estuary, as well as an important commercial and recreational resource. However, excessive amounts of nitrogen, phosphorus, and sediment from human activities and land development have disrupted the ecosystem, causing harmful algae blooms, degraded habitats, and diminished populations of many species of fish and shellfish. In 1983, the Chesapeake Bay Program (CBP) was established, based on a cooperative partnership among the U.S. Environmental Protection Agency (EPA), the state of Maryland, and the commonwealths of Pennsylvania and Virginia, and the District of Columbia, to address the extent, complexity, and sources of pollutants entering the Bay. In 2008, the CBP launched a series of initiatives to increase the transparency of the program and heighten its accountability and in 2009 an executive order injected new energy into the restoration. In addition, as part of the effect to improve the pace of progress and increase accountability in the Bay restoration, a two-year milestone strategy was introduced aimed at reducing overall pollution in the Bay by focusing on incremental, short-term commitments from each of the Bay jurisdictions. The National Research Council (NRC) established the Committee on the Evaluation of Chesapeake Bay Program Implementation for Nutrient Reduction in Improve Water Quality in 2009 in response to a request from the EPA. The committee was charged to assess the framework used by the states and the CBP for tracking nutrient and sediment control practices that are implemented in the Chesapeake Bay watershed and to evaluate the two-year milestone strategy. The committee was also to assess existing adaptive management strategies and to recommend improvements that could help CBP to meet its nutrient and sediment reduction goals. The committee did not attempt to identify every possible strategy that could be implemented but instead focused on approaches that are not being implemented to their full potential or that may have substantial, unrealized potential in the Bay watershed. Because many of these strategies have policy or societal implications that could not be fully evaluated by the committee, the strategies are not prioritized but are offered to encourage further consideration and exploration among the CBP partners and stakeholders.

Download or read book Eel Biology written by K. Aida and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a food resource in both Eastern and Western countries, the eel is an important fish. Over the years, remarkable progress has been achieved in understanding the mysterious life cycle of eels that has fascinated scientists since the age of Aristotle. The spawning area of the Japanese eel was discovered and the migratory route of its larvae was elucidated. With the development of techniques for artificial induction of gonadal maturation, it became possible to obtain hatched larvae. Larval rearing to the leptocephalus stage, one of the most difficult tasks involved in eel culture, finally was achieved. By presenting these important breakthroughs, Eel Biology will be of great help in the development of effective management strategies for maintaining stable eel populations. With contributions by leading experts, this book is a valuable source for researchers as well as industry technicians in the fields of aquatic biology, aquaculture, and fisheries.

Download or read book Statistical Methods in Water Resources written by D.R. Helsel and published by Elsevier. This book was released on 1993-03-03 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data on water quality and other environmental issues are being collected at an ever-increasing rate. In the past, however, the techniques used by scientists to interpret this data have not progressed as quickly. This is a book of modern statistical methods for analysis of practical problems in water quality and water resources.The last fifteen years have seen major advances in the fields of exploratory data analysis (EDA) and robust statistical methods. The 'real-life' characteristics of environmental data tend to drive analysis towards the use of these methods. These advances are presented in a practical and relevant format. Alternate methods are compared, highlighting the strengths and weaknesses of each as applied to environmental data. Techniques for trend analysis and dealing with water below the detection limit are topics covered, which are of great interest to consultants in water-quality and hydrology, scientists in state, provincial and federal water resources, and geological survey agencies.The practising water resources scientist will find the worked examples using actual field data from case studies of environmental problems, of real value. Exercises at the end of each chapter enable the mechanics of the methodological process to be fully understood, with data sets included on diskette for easy use. The result is a book that is both up-to-date and immediately relevant to ongoing work in the environmental and water sciences.

Download or read book Striper Wars written by Dick Russell and published by Island Press. This book was released on 2013-02-22 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: When populations of striped bass began plummeting in the early 1980s, author and fisherman Dick Russell was there to lead an Atlantic coast conservation campaign that resulted in one of the most remarkable wildlife comebacks in the history of fisheries. As any avid fisherman will tell you, the striped bass has long been a favorite at the American dinner table; in fact, we've been feasting on the fish from the time of the Pilgrims. By 1980 that feasting had turned to overfishing by commercial fishing interests. Striper Wars is Dick Russell's inspiring account of the people and events responsible for the successful preservation of one of America's favorite fish and of what has happened since. Striper Wars is a tale replete with heroes--and some villains--as the struggle to save the striper migrated down the coast from Massachusetts to Maryland. Russell introduces us to a postman at arms against a burly trap-net fisherman, a renowned state governor caving to special interests, and a fishing-tackle maker fighting alongside marine biologists. And he describes how champions of this singular fish blocked power plants and New York's Westway Project that would otherwise compromise its habitat. Unfortunately, those who cheered the triumphant ending to the campaign, as the coastal states enacted measures that enabled the striped bass to make its comeback, have found the peace transitory--there is now a new enemy emerging on the front. In recent years a chronic bacterial disease has struck more than seventy percent of the striped bass population in the primary spawning waters of the Chesapeake Bay. Malnutrition seems to be a significant factor, brought on by the same overfishing that plagued the bass in the first battle--only this time, the overfishing is devastating menhaden, the silvery little fish upon which the bass feed. Lessons learned during the first conservation battle are being applied here, highlighting a need for a whole new ecosystem-based approach to conserving species. Only with constant vigilance by concerned citizens, Dick Russell reminds us, can environmental victories be sustained. This particular fish story is a personal one for him, and he follows the striper's saga today all the way to California, where the fish was introduced in 1879 and where agribusiness now threatens its future. For his conservation work during the 1980s Russell received a citizen's Chevron Conservation Award.
