Book Upstream Passage  Spawning  and Stock Identification of Fall Chinook Salmon in the Snake River  1992

Download or read book Upstream Passage Spawning and Stock Identification of Fall Chinook Salmon in the Snake River 1992 written by and published by . This book was released on 1993 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the activities and results for the second year (1992) of a three year study. The goals of the study were as follows: (1) to determine the source (s) of interdam losses of adult fall chinook salmon between Ice Harbor Dam (IHR) and Lower Granite Dam (LGR), as well as upstream of LGR; (2) identify spawning locations upstream of LGR for calibration of aerial redd surveys, and to assist with redd habitat mapping and carcass recovery (for genetic stock profile analysis). Radio telemetry was used as the method of addressing project goals. Unmarked (not adipose clipped) adult fall chinook salmon were trapped and radio tagged at IHR and LGR dams as they ascended the Snake River during their spawning migration. They used aerial and ground mobile radio tracking to determine the movements of these fish. They examined movements of all radio tagged salmon upstream of LGR Dam. That provided us with a sample of 17 radio tagged fish tagged at IHR and 20 tagged at LGR. They estimate a combined fall back rate at LGR of 37.1% (13 fish). Another 10.8--13.5% were 'lost' or prespawning mortalities. They identified two potential spawning locations that would not have been detected from the aerial spawning surveys. One site was upstream of Troy on the Grande Ronde River and the other was in the upper Snake River.

This book was released on 1997 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: This final report of the 3-year study summarizes activities and results for 1993. Study objectives were to: (1) determine the source of losses (or accounting errors) for adult chinook salmon between Ice Harbor Dam (IHR) and Lower Granite Dam (LGR), and upstream of LGR in the Snake River; (2) identify spawning locations upstream of LGR for calibration of aerial redd surveys, redd habitat mapping, carcass recovery for genetic stock profile analysis, and correction of estimated adult/redd ratios; and (3) estimate passage and migration times at Snake River. 200 fall chinook salmon were radio tagged and tracked with aerial, fixed-site, and ground mobile tracking. Fish were released upstream of IHR at Charbonneau Park (CHAR). 190 of the fish were tracked or relocated away from CHAR. 59 fish descended to below IHR without crossing Lower Monumental Dam (LMO). Another 128 salmon passed upstream of LMO without falling back at IHR. Only 80 salmon passed Little Goose Dam (LGO) without falling back at a downstream dam; 66 of these fish passed LGR. Many fish that fell back reascended the dams. A total of 72 salmon released at CHAR passed upstream of LGR, including fish that had fallen back and reascended a dam. Over 80 percent of the salmon that entered Lyons Ferry Hatchery each year had reached LGO before descending to the hatchery. Extensive wandering was documented between LMO and upstream of LGR before salmon entered Lyons Ferry Hatchery or the Tucannon River. In 1993, 41 salmon were found to be of hatchery origin when recovered. These fish entered Lyons Ferry Hatchery with similar movements to unmarked salmon. Each year a few salmon have remained near the hatchery without entering, which suggests the hatchery may have inadequate attraction flows. Fall chinook passed lower Snake River dams in 2-5 days each on average. Median travel times through LMO and LGO were 1.0-1.3 days each, which was slower than for spring chinook or steelhead in 1993. 5 refs., 21 figs., 20 tabs.

Book Identification of the Spawning  Rearing and Migratory Requirements of Fall Chinook Salmon in the Columbia River Basin  Annual Report 1992

Download or read book Identification of the Spawning Rearing and Migratory Requirements of Fall Chinook Salmon in the Columbia River Basin Annual Report 1992 written by and published by . This book was released on 1994 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document is the 1992 annual progress report for selected studies of fall chinook Salmon Oncorhynchus tshawytscha conducted by the National Biological Survey (NBS) and the US Fish and Wildlife Service. The decline in abundance of fall chinook salmon in the Snake River basin has become a growing concern. Effective recovery efforts for fall chinook salmon cannot be developed until we increase our knowledge of the factors that are limiting the various life history stages. This study attempts to identify those physical and biological factors which influence spawning of fall chinook salmon in the free-flowing Snake River and their rearing and seaward migration through Columbia River basin reservoirs.

Book excerpt: This document is the 1991 annual progress report for selected studies of fall chinook salmon Oncorhynchus tshawytscha conducted by the US Fish and Wildlife Service. The decline in abundance of fall chinook salmon in the Snake River basin has become a growing concern. In April 1992, Snake River fall chinook salmon were listed as ''threatened'' under the Endangered Species Act. Effective recovery efforts for fall chinook salmon can not be developed until we increase our knowledge of the factors that are limiting the various life history stages. This study attempts to identify those physical and biological factors which influence spawning of fall chinook salmon in the free-flowing Snake River and their rearing and seaward migration through Columbia River basin reservoirs.

This book was released on 2008 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Redd counts are routinely used to document the spawning distribution of fall Chinook salmon (Oncorhynchus tshawytscha) in the Snake River basin upriver of Lower Granite Dam. The first reported redd counts were from aerial searches conducted intermittently between 1959 and 1978 (Irving and Bjornn 1981, Witty 1988; Groves and Chandler 1996)(Appendix 1). In 1986, the Washington Department of Fish and Wildlife began an annual monitoring program that, in addition to the Snake River, included aerial searches of the Grande Ronde River the first year (Seidel and Bugert 1987), and the Imnaha River in subsequent years (Seidel et al. 1988; Bugert et al. 1989-1991; Mendel et al. 1992). The U.S. Fish and Wildlife Service and Idaho Power Company began contributing to this effort in 1991 by increasing the number of aerial searches conducted each year and adding underwater searches in areas of the Snake River that were too deep to be searched from the air (Connor et al. 1993; Garcia et al. 1994a, 1994b, 1996-2007; Groves 1993; Groves and Chandler 1996). The Nez Perce Tribe added aerial searches in the Clearwater River basin beginning in 1988 (Arnsberg et. al 1992), and the Salmon River beginning in 1992. Currently searches are conducted cooperatively by the Nez Perce Tribe, Idaho Power Company, and U.S. Fish and Wildlife Service. Our objective for this report was to consolidate the findings from annual redd searches counted upstream of Lower Granite Dam into a single document, containing detailed information about the searches from the most recent spawning season, and summary information from previous years. The work conducted in 2007 was funded by the Bonneville Power Administration and Idaho Power Company.
