This book was released on 1985 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: The historic and present ranges of anadromous alosids and striped bass were determined for three of Virginia's rivers. American shad, blueback herring, and alewives migrated to at least Remington (river mile 188) on the Rappahannock River. They ascended the entire length of the York River, reaching at least Milford on the Mattaponi and the entire length of the Pamunkey. The alosids traversed the full length of the James River, reaching above Clifton Forge and Covington. Although striped bass were historically caught in the James as far upstream as Balcony Falls (near Glasgow) and probably as far upstream as shad on the other rivers, it is doubtful that they ever spawned above the fall line on any river. Present ranges for all species are Fredericksburg (Embrey Dam) on the Rappahannock, unchanged on the York, and Richmond (Bosher Dam) on the James. One dam on the Rappahannock River and twelve dams on the James River were identified as actual or potential barriers to the upstream spawning migrations of Virginia's anadromous fishes. Elimination of these barriers by breaching, in the case of unused facilities, or by the construction of fish passage facilities would result in the restoration of 47 miles of mainstem river (a 30% increase) on the Rappahannock and 226 miles (a 200% increase) on the James. Water quality was found not to be sufficiently degraded on these rivers to impede spawning migrations of anadromous fish. The dams identified on the James and Rappahannock Rivers were investigated to assess the feasibility of eliminating them as barriers to upstream migration of anadromous fish, and to project a timetable estimating the probable dates of accomplishment. The Embrey Dam at Fredericksburg on the Rappahannock may soon be modified to permit fish passage. On the James, five dams at Richmond are currently being considered for passage modifications; access to an additional 139 miles of the James appears likely by the early 1990s. Access to the remainder of the upper James River is blocked by a series of seven hydropower dams in the Lynchburg area. Passage around this series of barriers cannot plausibly be anticipated for at least 30 years. Biological requirements for passage of the anadromous species, and a synthesis of the state of knowledge of fish passage facilities and fish passage through culverts are included in this report.

Download or read book Climate Change and Indigenous Peoples in the United States written by Julie Koppel Maldonado and published by Springer. This book was released on 2014-04-05 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: With a long history and deep connection to the Earth’s resources, indigenous peoples have an intimate understanding and ability to observe the impacts linked to climate change. Traditional ecological knowledge and tribal experience play a key role in developing future scientific solutions for adaptation to the impacts. The book explores climate-related issues for indigenous communities in the United States, including loss of traditional knowledge, forests and ecosystems, food security and traditional foods, as well as water, Arctic sea ice loss, permafrost thaw and relocation. The book also highlights how tribal communities and programs are responding to the changing environments. Fifty authors from tribal communities, academia, government agencies and NGOs contributed to the book. Previously published in Climatic Change, Volume 120, Issue 3, 2013.

Book Synopsis On the Dynamics of Exploited Fish Populations by : Raymond J.H. Beverton

This book was released on 2012-12-06 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the fishes, a remarkably wide range of biological adaptations to diverse habitats has evolved. As well as living in the conventional habitats of lakes, ponds, rivers, rock pools and the open sea, fish have solved the problems of life in deserts, in the deep sea, in the cold antarctic, and in warm waters of high alkalinity or of low oxygen. Along with these adaptations, we find the most impressive specializations of morphology, physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins, sailfish and warm-blooded tunas, air-breathing in catfish and lungfish, parental care in the mouth-brooding cichlids, and viviparity in many sharks and toothcarps. Moreover, fish are of considerable importance to the survival of the human species in the form of nutritious, delicious and diverse food. Rational exploitation and management of our global stocks of fishes must rely upon a detailed and precise insight of their biology. The Chapman & Hall Fish and Fisheries Series aims to present timely volumes reviewing important aspects of fish biology. Most volumes will be of interest to research workers in biology, zoology, ecology and physiology but an additional aim is for the books to be accessible to a wide spectrum of non-specialist readers ranging from undergraduates and postgraduates to those with an interest in industrial and commercial aspects of fish and fisheries.

Book Synopsis Handbook of Fish Biology and Fisheries by : Paul J. B. Hart
Download or read book Handbook of Fish Biology and Fisheries written by Paul J. B. Hart and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent decades have witnessed strong declines in fish stocks aroundthe globe, amid growing concerns about the impact of fisheries onmarine and freshwater biodiversity. Fisheries biologists andmanagers are therefore increasingly asking about aspects ofecology, behaviour, evolution and biodiversity that weretraditionally studied by people working in very separate fields.This has highlighted the need to work more closely together, inorder to help ensure future success both in management andconservation. The Handbook of Fish Biology and Fisheries has beenwritten by an international team of scientists and practitioners,to provide an overview of the biology of freshwater and marine fishspecies together with the science that supports fisheriesmanagement and conservation. This volume, subtitled Fish Biology, reviews a broadvariety of topics from evolutionary relationships and globalbiogeography to physiology, recruitment, life histories, genetics,foraging behaviour, reproductive behaviour and community ecology.The second volume, subtitled Fisheries, uses much of thisinformation in a wide-ranging review of fisheries biology,including methods of capture, marketing, economics, stockassessment, forecasting, ecosystem impacts and conservation. Together, these books present the state of the art in ourunderstanding of fish biology and fisheries and will serve asvaluable references for undergraduates and graduates looking for acomprehensive source on a wide variety of topics in fisheriesscience. They will also be useful to researchers who needup-to-date reviews of topics that impinge on their fields, anddecision makers who need to appreciate the scientific backgroundfor management and conservation of aquatic ecosystems.

Provides a unique overview of the study of fish biology andecology, and the assessment and management of fish populations andecosystems. The first volume concentrates on aspects of fish biology andecology, both at the individual and population levels, whilst thesecond volume addresses the assessment and management of fishpopulations and ecosystems. Written by an international team of expert scientists andpractitioners. An invaluable reference tool for both students, researchers andpractitioners working in the fields of fish biology andfisheries.

Book Synopsis Riparian Areas by : National Research Council
Download or read book Riparian Areas written by National Research Council and published by National Academies Press. This book was released on 2002-10-10 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.
Book Synopsis Aquaculture Management by : James W. Meade
Download or read book Aquaculture Management written by James W. Meade and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although some nations, such as Japan, have invested in aquaculture research and developed major aquaculture industries, the opportunities for similar devel opment in the United States remain largely unnoticed. In a typical recent year the United States, which claims 20% of the world's marine fisheries resources, imported seafood worth $4. 8 billion and exported $l. 3 billion. In addition to the $3. 5 billion deficit in food-fish, was another $2. 7 billion deficit for nonedible fishery products. Next to oil, fishery products constituted the second highest drain on the United States balance of payments and accounts for a significant portion of the foreign trade deficit. Furthermore, fish consumption has been increasing in North America. In response to the demand for fishery products, aquaculture managers not only have the opportunity to realize economic profit, but in doing so can make an important contribution to reducing the national debt, providing employment, and enhancing our diet. This book might be considered a farm management text for those in aquaculture. It is intended to provide an introduction to aquaculture principles and an introduction to management, including business and people management, microeconomics, and the concepts of efficiency and productivity. I hope it will bridge the gap between conservationists, the academic community, and commer cial culturists. Abundant references should enable the reader to quickly access literature on most topics germane to the management of culture systems.
