This book was released on 2013-11-20 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wild salmon, trout, char, grayling, and whitefish (collectively salmonids) have been a significant local food and cultural resource for Pacific Northwest peoples for millennia. The location, size, and distribution of urban areas along streams, rivers, estuaries, and coasts directly and indirectly alter and degrade wild salmonid populations and their habitats. Although urban and exurban areas typically cover a smaller fraction of the landscape than other land uses combined, they have profound consequences for local ecosystems, aquatic and terrestrial populations, and water quality and quantity.

Download or read book Renews River Salmonid Research Project written by Geoffrey Veinott and published by . This book was released on 2010 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides an overview of the data collected in the second year (2008) of a planned six year study of salmonid populations in the Renews River watershed. Distribution and abundance of juvenile Atlantic salmon and brown trout in the main stem of the river was similar to that reported in 2007. Juvenile fish densities remain low. Growth and condition indices remained comparable to 2007 data, but brook trout caught in Big Butterpot Pond in the winter only weighed 77% of the North American standard for brook trout in good condition. There was a shift to smaller fish being caught in the recreational brown trout fishery in 2008 compared to 2007. In 2008 the modal size group was 15-20 cm compared with 30-35 cm in 2007. An estimated 260 fish were taken in the brown trout fishery with the highest numbers of fish taken in the evenings and on weekdays. The greatest effort occurred early in the angling season when the largest fish were taken. Acoustic tags revealed that some brown trout smolt, decending the river in spring, leave the harbour and at least one brown trout migrated northward along the coast for at least 16 km. Large numbers of juvenile salmon and trout, 2 and 3 years of age, descend the river in the spring and are likely the main source of recruitment for the recreational fishery. Only 4% of the brown trout sampled in the recreational fishery showed any spawning marks on their scales. First spawning occurs at age 4 or 5. The total number of seals counted in the harbour in 2008 decreased by 70% over 2007. There was also a significant decline in the average number of cormorants and terns in 2008 compared to 2007. There was no evidence of anthropogenitic pollution entering Renews River but peak water temperatures frequently exceeded 25°C and at times would be considered lethal for juvenile salmonids.

Download or read book Strategies for Conserving Native Salmonid Populations at Risk from Nonnative Fish Invasions written by Kurt D. Fausch and published by . This book was released on 2006 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Native salmonid populations in the inland West are often restricted to small isolated habitats at risk from invasion by nonnative salmonids. However, further isolating these populations using barriers to prevent invasions can increase their extinction risk. This monograph reviews the state of knowledge about this tradeoff between invasion and isolation. We present a conceptual framework to guide analysis, focusing on four main questions concerning conservation value, vulnerability to invasion, persistence given isolation, and priorities when conserving multiple populations. Two examples illustrate use of the framework, and a final section discusses opportunities for making strategic decisions when faced with the invasion-isolation tradeoff.

This book was released on 2012-12-06 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: The monitoring of point sources by the Environmental Protection Agency (EPA), the states, and the tribes has documented and helped reduce the levels of chemical stressors affecting our ecosystems. With the controls on point sources reducing chemical contamination, new environmental challenges associated with nonpoint sources have emerged. To adequately deal with these new problems, EPA's Office of Research and Development recognized the need to develop an overall under standing of the condition of our ecological resources, the trends in their condition, and the stressors affecting these systems on a broad scale. Toward this end, the En vironmental Monitoring and Assessment Program (EMAP) was established by EPA and has been strategically developing the scientific tools and techniques to monitor and assess the status and trends of aquatic ecosystems. EMAP scientists have developed new indicators and probability-based de signs to fill data gaps in the development of regional-scale assessments of our aquatic resources, as required in the Clean Water Act. We have a scientifically de fensible approach that allows: 100 percent coverage of the aquatic resources within broad geographic areas and the formulation of reference 'conditions for es tablishing the health of these resources. The use of these indicators and designs were successfully demonstrated in the landscapes, streams, and estuaries of the mid-Atlantic states as part of the Mid-Atlantic Integrated Assessment (MAlA).

This book was released on 2002 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns about the decline of native salmon and trout populations have increased among natural resource managers and the public in recent years. As a result, a multitude of initiatives have been implemented at the local, state, and federal government levels. These initiatives include management plans and actions intended to protect and restore salmonid fishes and their habitats. In 1998 bull trout (Salvelinus confluentus) were listed under the Endangered Species Act (ESA), as ''Threatened'', for the Walla Walla River and its tributaries. Steelhead (Oncorhynchus mykiss) were listed as ''Threatened'' in 1999 for the mid-Columbia River and its tributaries. These ESA listings emphasize the need for information about these threatened salmonid populations and their habitats. The Washington Department of Fish and Wildlife (WDFW) is entrusted with ''the preservation, protection, and perpetuation of fish and wildlife ... [and to] maximize public recreational or commercial opportunities without impairing the supply of fish and wildlife (WAC 77.12.010).'' In consideration of this mandate, the WDFW submitted a proposal in December 1997 to the Bonneville Power Administration (BPA) for a study to assess salmonid distribution, relative abundance, genetics, and the condition of salmonid habitats in the Walla Walla River basin. The primary purposes of this project are to collect baseline biological and habitat data, to identify major data gaps, and to draw conclusions whenever possible. The study reported herein details the findings of the 2001 field season (March to November, 2001).
