Book excerpt: Return to the River will describe a new ecosystem-based approach to the restoration of salmon and steelhead populations in the Columbia River, once one of the most productive river basins for anadromous salmonids on the west coast of North America. The approach of this work has broad applicability to all recovery efforts throughout the northern hemisphere and general applicability to fisheries and aquatic restoration efforts throughout the world. The Pacific Northwest is now embroiled in a major public policy debate over the management and restoration of Pacific salmon. The outcome of the debate has the potential to affect major segments of the region's economy - river transportation, hydroelectric production, irrigated agriculture, urban growth, commercial and sport fisheries, etc. This debate, centered as it is on the salmon in all the rivers, has created a huge demand for information. The book will be a powerful addition to that debate. A 15 year collaboration by a diverse group of scientists working on the management and recovery of salmon, steelhead trout, and wildlife populations in the Pacific Northwest Includes over 200 figures, with four-color throughout the book Discusses complex issues such as habitat degradation, juvenile survival through the hydrosystem, the role of artificial production, and harvest reform

Download or read book Ecological Condition of the Columbia River Estuary written by Gretchen Ann Hayslip and published by . This book was released on 2007 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Columbia River estuary is a unique and important ecological resource. EPA's National Estuary Program (NEP) was established by Congress in 1987 in Clean Water Act amendments to improve the quality of estuaries of national significance. The Columbia River estuary is one of 28 estuaries in the NEP. The overall quality of the Columbia River estuary, which forms the border between Washington and Oregon, is described in this report using data collected as part of the Western Environmental Monitoring and Assessment Program (EMAP). EMAP was initiated by EPA's Office of Research and Development (ORD) to estimate the current status and trends in the condition of nation's ecological resources. EMAP also examines associations between these indicators and natural and human-caused stressors. The coastal component of EMAP's monitoring and assessment tools are used to create an integrated and comprehensive coastal monitoring program of coastal ecosystems. Water column measurements are combined with information about sediment characteristics and chemistry, benthic organisms, and fish to describe the current estuarine condition. Sampling began during the summer of 1999, with small estuaries of the Columbia River. In 2000, sampling continued with the larger Columbia River estuary. The boundary for the Columbia River estuary was head of tidal influence, so there were some freshwater components of this sampling effort. The Washington Department of Ecology (Ecology), and the Oregon Department of Environmental Quality (ODEQ) conducted all field sampling for this project in 1999-2000 with assistance from EPA Region 10 and the National Marine Fisheries Service (NMFS). This project was designed to evaluate the overall condition of the Columbia River estuary. For water physical/chemical parameters, 7% of the area of the Columbia River estuary was in fair/poor condition, while nutrient indicators (nitrogen, phosphorus and chlorophyll a) showed a larger percent of the area (31- 46%) in the fair/poor condition category. For sediment indicators, total organic carbon showed none of the areas was in poor condition, but for sediment contaminants approximately 16% of the Columbia River estuarine area was in poor condition. As for biological indicators (chemicals in fish tissue and percent Corbicula), for chemicals in fish tissue, 39% of the area was in fair/poor condition. An even higher percent of the Columbia River estuary (66%) was in poor condition using percent Corbicula, a nonindigenous species, as an indictor. In 2006, we evaluated the ecological condition of the estuaries of Oregon and Washington (Hayslip, et al., 2006). The percent area in fair/poor condition for every indicator we evaluated was higher in the Columbia River estuary. The only exception was for chemicals in fish tissue where we found 47% of the area for estuaries of Oregon and Washington in fair/poor condition and 39% in the Columbia River estuary in fair/poor condition."--Executive summary (page v).
Download or read book Ecology of Salmonids in Estuaries around the World written by Colin D. Levings and published by UBC Press. This book was released on 2016-05-15 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: For centuries, biologists have marvelled at how anadromous salmonids – fish that pass from rivers into oceans and back again – survive as they migrate between these two very different environments. Yet, relatively little is understood about what happens to salmonid species (including salmon, steelhead, char, and trout) in the estuaries where they make this transition from fresh to salt water. This book explains the critical role estuaries play in salmonid survival. Ecology of Salmonids in Estuaries around the World synthesizes information from a vast array of literature, to describe the specific adaptation of eighteen anadromous salmonids in four genera (Hucho, Oncorhynchus, Salmo, and Salvelinus) explain the ecological relationships between anadromous salmonids, the fish they coexist with, and their estuarine habitat discuss key fitness elements salmonids need for survival (including those relating to osmoregulation, growth and feeding mechanisms, and biotic interactions) provide guidance on how to conduct estuarine sampling and scientific aspects of management and recovery plans offer directions for future research. The critical reference is further enhanced by extensive supplementary appendices that are available online, including data tables, additional references on estuarine salmonids, and a primer on estuaries and salmonids for citizen scientists.
Download or read book Basics of Marine and Estuarine Ecology written by Abhijit Mitra and published by Springer. This book was released on 2016-02-02 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents recent research on marine ecology in different parts of the world. It aims to shed light on relevant topics for budding marine ecologists. The “blue soup” of Planet Earth, which comprises both biotic and abiotic components, is essential to keeping the wheel of civilization running. Four major ecosystem service categories have been identified within this context, namely provisioning services such as water, food, mangrove timber, honey, fish, wax, fuel wood, fodder and bioactive compounds from marine and estuarine flora and fauna; regulating services such as the regulation of climate, coastal erosion, coral bleaching and pollution; cultural services encompassing recreational (tourism), spiritual and other non-material benefits; and supporting services such as nutrient cycling and photosynthesis. These valuable services are obtained from various resources that must be conserved for the sake of humanity. This book presents data for each resource type, not just in the form of a simple description, but also through case studies that resulted from several research projects and pilot programs carried out in different parts of the world. Statistical tools were also used to critically analyze the influence of relevant hydrological parameters on the biotic community. Advanced research in marine and estuarine ecology is based on the use of sophisticated instruments, sampling precision, statistical tools, etc., which have also been highlighted in the book.
