Download or read book Evaluation of the Life History of Native Salmonids in the Malheur River Basin Cooperative Bull Trout written by and published by . This book was released on 2001 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Malheur basin lies within southeastern Oregon. The Malheur River is a tributary to the Snake River, entering at about River Kilometer (RK) 595. The hydrological drainage area of the Malheur River is approximately 12,950 km2 and is roughly 306 km in length. The headwaters of the Malheur River originate in the Blue Mountains at elevations of 6,500 to 7,500 feet, and drops to an elevation of 2000 feet at the confluence with the Snake River near Ontario, Oregon. The climate of the Malheur basin is characterized by hot dry summers, occasionally exceeding 38 C and cold winters that may drop below -29 C. Average annual precipitation is 300 centimeters and ranges from 100 centimeters in the upper mountains to less than 25 centimeters in the lower reaches (Gonzalez 1999). Wooded areas consist primarily of mixed fir and pine forest in the higher elevations. Sagebrush and grass communities dominate the flora in the lower elevations. Efforts to document salmonid life histories, water quality, and habitat conditions have continued in fiscal year 2000. The Burns Paiute Tribe (BPT), United States Forest Service (USFS), and Oregon Department of Fish and Wildlife (ODFW), have been working cooperatively to achieve this common goal. Bull trout ''Salvenlinus confluentus'' have specific environmental requirements and complex life histories making them especially susceptible to human activities that alter their habitat (Howell and Buchanan 1992). Bull trout are considered to be a cold-water species and are temperature dependent. This presents a challenge for managers, biologists, and private landowners in the Malheur basin. Because of the listing of bull trout under the Endangered Species Act as threatened and the current health of the landscape, a workgroup was formed to develop project objectives related to bull trout. This report will reflect work completed during the Bonneville Power contract period starting 1 April 2000 and ending 31 March 2001. The study area will include the North Fork Malheur River and the Upper Malheur River from Warm Springs Reservoir upstream to the headwaters.

Book Genetic Monitoring of Snake River Salmonids

Download or read book Genetic Monitoring of Snake River Salmonids written by Audrey C. Harris and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the application of genetic techniques to the management and conservation of anadromous salmonids (steelhead Oncorhynchus mykiss and spring-summer Chinook Salmon O. tshawytscha) in the Snake River basin. In 2010, Idaho Department of Fish and Game, in collaboration with the Columbia River Inter-Tribal Fish Commission, initiated two BPA-funded projects (2010-026-00 and 2010-031-00) to test and implement genetic monitoring programs for Snake River basin steelhead and spring-summer Chinook Salmon utilizing two genetic technologies that identify origins of hatchery and wild fish. The first technology, called parentage‐based tagging (PBT), involves annually sampling and genotyping all hatchery broodstock which are added to a genetic baseline of candidate parents. The genotyping of broodstock permanently genetically “tags” all of their offspring. A non‐lethal tissue sample from any offspring of these broodstock can be genotyped and analyses can be completed to assign parentage, thereby identifying hatchery of origin and age. The second technology is called genetic stock identification (GSI) and involves creating a reference genetic baseline from all contributing wild stocks. Wild fish of unknown origin can then be non-lethally sampled, genotyped, and assigned to a stock of origin via assignment testing. Over the last decade, these projects have demonstrated the accuracy, efficiency, and utility of these technologies for monitoring both wild and hatchery stocks throughout the Snake River and Columbia River basins. For hatchery stocks, PBT addresses objectives established by the Bonneville Power Administration (BPA) Fish and Wildlife Program which involves marking hatchery stocks, conducting hatchery evaluations and reform, and enforcing salmonid fishery management measures. For wild stocks, GSI provides unprecedented tools for monitoring wild stock abundance, productivity, and genetic diversity, which are required for NOAA ESA status assessments. These two projects were combined by BPA in 2021 (2010-031-00), with ongoing goals of keeping PBT and GSI baselines up-to-date in the Snake River basin, to maintain and enhance SNP genetic marker panels, and to continue projects that use these PBT and GSI baselines to address conservation and management issues of importance to the Northwest Power and Conservation Council and state, tribal and federal fisheries managers. Combined there are eight objectives addressed in this report: 1) the maintenance and evaluation of single nucleotide polymorphism (SNP) panels for high-throughput genotyping of steelhead and Chinook Salmon in the Snake and Columbia river basins; 2) the updating, maintenance, and testing of SNP baselines to describe genetic variation and for use as a reference in conducting GSI for both species; 3) annual sampling of hatchery broodstock and creation of genetic parental databases; 4) utilization of PBT and GSI baselines to estimate genetic stock composition and life history diversity of steelhead and spring-summer Chinook Salmon passing Lower Granite Dam (LGR); 5) application of PBT baselines to estimate the stock composition of steelhead in the Columbia and Snake River tribal and sport fisheries; 6) the monitoring of integrated hatchery programs for Chinook Salmon; 7) the summarization of life history and genetic diversity information for steelhead and spring-summer Chinook Salmon detected at PIT tag detection systems; and 8) the development and application of grandparentage technology for use in the Snake River basin.

Book Assessment of Salmonids and Their Habitat Conditions in the Walla Walla River Basin of Washington

Download or read book Assessment of Salmonids and Their Habitat Conditions in the Walla Walla River Basin of Washington written by and published by . This book was released on 2001 with total page 116 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 were listed under the Endangered Species Act (ESA), as ''Threatened'', for the Walla Walla River and its tributaries. Steelhead were listed as ''Threatened'' in 1999 for the mid-Columbia River and its tributaries. These ESA listings emphasize the need for information about the 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 their 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 2000 field season (March to November, 2000).
