Nez Perce Tribe Rocklage (De) and published by . This book was released on 2005 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Nez Perce Tribe, in cooperation with the U.S. Fish and Wildlife Service and Washington Department of Fish and Wildlife, conducted monitoring and evaluation studies on Lyons Ferry Hatchery reared yearling fall Chinook salmon Oncorhynchus tshawytscha that were acclimated and released at three Fall Chinook Acclimation Project (FCAP) sites upstream of Lower Granite Dam in 2004. This was the ninth year of a long-term project to supplement natural spawning populations of Snake River stock fall Chinook salmon upstream of Lower Granite Dam. The 414,452 yearlings released from the Fall Chinook Acclimation Project facilities were short of the 450,000 fish quota. We use Passive Integrated Transponder (PIT) tag technology to monitor the primary performance measures of survival to mainstem dams and migration timing. We also monitor size, condition and tag/mark retention at release. We released 4,983 PIT tagged yearlings from Pittsburg Landing, 4,984 from Big Canyon and 4,982 from Captain John Rapids. Fish health sampling indicated that, overall, bacterial kidney disease levels could be considered low with 53-94% rating not detected to low. Mean fork lengths (95% confidence interval) of the PIT tagged groups ranged from 154.6 mm (154.0-155.2 mm) at Pittsburg Landing to 163.0 mm (162.6-163.4 mm) at Captain John Rapids. Mean condition factors ranged from 1.06 at Lyons Ferry Hatchery to 1.16 at Big Canyon. Estimated survival (95% confidence interval) of PIT tagged yearlings from release to Lower Granite Dam ranged from 74.7% (72.9-76.5%) for Big Canyon to 88.1% (85.7-90.6%) for Captain John Rapids. Estimated survival from release to McNary Dam ranged from 45.3% (39.2-51.5%) for Pittsburg Landing to 52.1% (42.9-61.2%) for Big Canyon. Median migration rates to Lower Granite Dam, based on all observations of PIT tagged yearlings from the FCAP facilities, ranged from 5.5 river kilometers per day (rkm/d) for Captain John Rapids to 12.8 rkm/d for Pittsburg Landing. Median migration rates to McNary Dam ranged from 10.9 rkm/d for Captain John Rapids to 17.6 rkm/d for Pittsburg Landing. Median travel times from the FCAP facilities were about 13-16 days to Lower Granite Dam and 23-29 days to McNary Dam. Median arrival dates at Lower Granite Dam, based on all observations of PIT tagged yearling groups from Pittsburg Landing, Big Canyon and Captain John Rapids, ranged from April 18-29. Median arrival dates at McNary Dam for Pittsburg Landing, Big Canyon and Captain John Rapids groups ranged from May 1-8.

Rocklage and published by . This book was released on 2004 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Nez Perce Tribe, in cooperation with the U.S. Fish and Wildlife Service and Washington Department of Fish and Wildlife, conducted monitoring and evaluation studies on Lyons Ferry Hatchery (Snake River stock) yearling fall chinook salmon that were acclimated and released at three Fall Chinook Acclimation Project sites upstream of Lower Granite Dam along with yearlings released on-station from Lyons Ferry Hatchery in 1998. The three fall chinook acclimation facilities are operated by the Nez Perce Tribe and located at Pittsburg Landing and Captain John Rapids on the Snake River and at Big Canyon Creek on the Clearwater River. Yearlings at the Big Canyon facility consisted of two size classes that are referred to in this report as 9.5 fish per pound (fpp) and 30 fpp. The Big Canyon 9.5 fpp were comparable to the yearlings at Pittsburg Landing, Captain John Rapids and Lyons Ferry Hatchery. A total of 9,942 yearlings were PIT tagged and released at Pittsburg Landing. PIT tagged yearlings had a mean fork length of 159.9 mm and mean condition factor of 1.19. Of the 9,942 PIT tagged fish released, a total of 6,836 unique tags were detected at mainstem Snake and Columbia River dams (Lower Granite, Little Goose, Lower Monumental and McNary). A total of 4,926 9.5 fpp and 2,532 30 fpp yearlings were PIT tagged and released at Big Canyon. PIT tagged 9.5 fpp yearlings had a mean fork length of 156.9 mm and mean condition factor of 1.13. PIT tagged 30 fpp yearlings had a mean fork length of 113.1 mm and mean condition factor of 1.18.

Book excerpt: The Nez Perce Tribe, in cooperation with the U.S. Fish and Wildlife Service and Washington Department of Fish and Wildlife, conducted monitoring and evaluation studies on Lyons Ferry Hatchery reared yearling fall Chinook salmon Oncorhynchus tshawytscha that were acclimated and released at three Fall Chinook Acclimation Project sites upstream of Lower Granite Dam along with yearlings released on-station from Lyons Ferry Hatchery in 2000. This was the fifth year of a long-term project to supplement natural spawning populations of Snake River stock fall Chinook salmon upstream of Lower Granite Dam. The 397,339 yearlings released from the Fall Chinook Acclimation Project facilities were short of the 450,000 fish quota. We use Passive Integrated Transponder (PIT) tag technology to monitor the primary performance measures of survival to mainstem dams and migration timing. We also monitor size, condition and tag/mark retention at release. We released 7,477 PIT tagged yearlings from Pittsburg Landing, 7,421 from Big Canyon and 2,488 from Captain John Rapids. The Washington Department of Fish and Wildlife released 980 PIT tagged yearlings from Lyons Ferry Hatchery. Fish health sampling indicated that, overall, bacterial kidney disease levels could be considered relatively low. Compared to prior years, Quantitative Health Assessment Indices were relatively low at Big Canyon and Captain John Rapids and about average at Pittsburg Landing and Lyons Ferry Hatchery. Mean fork lengths (95% confidence interval) of the PIT tagged groups ranged from 157.7 mm (157.3-158.1 mm) at Big Canyon to 172.9 mm (172.2-173.6 mm) at Captain John Rapids. Mean condition factors ranged from 1.06 at Captain John Rapids and Lyons Ferry Hatchery to 1.12 at Big Canyon. Estimated survival (95% confidence interval) of PIT tagged yearlings from release to Lower Granite Dam ranged from 87.0% (84.7-89.4%) for Pittsburg Landing to 95.2% (91.5-98.9%) for Captain John Rapids. Estimated survival from release to McNary Dam ranged from 65.8% (58.5-73.1%) for Lyons Ferry Hatchery to 84.0% (76.2-91.8%) for Captain John Rapids. Median migration rates to Lower Granite Dam, based on all observations of PIT tagged yearlings from the FCAP facilities, ranged from 10.1 river kilometers per day (rkm/d) for Captain John Rapids to 19.1 rkm/d for Pittsburg Landing. Median migration rates to McNary Dam ranged from 6.0 rkm/d for Lyons Ferry Hatchery to 17.3 rkm/d for Pittsburg Landing. Median travel times from the FCAP facilities were about 9-10 days to Lower Granite Dam and 22-25 days to McNary Dam. Median arrival dates at Lower Granite Dam, based on all observations of PIT tagged yearling groups from Pittsburg Landing, Big Canyon and Captain John Rapids, were all from April 21-22.

This book was released on 2005 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Redd counts were 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, 1996-2004; 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 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 2004 was funded by the Bonneville Power Administration, Idaho Power Company, and Bureau of Land Management.

This book was released on 1991 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efforts have been initiated to develop a research plan that will provide insight into causes of, and ultimately solutions to, the apparent excessive mortality of juvenile chinook upstream from Lower Granite Dam on the Snake River. In the context of the proposed salmon stock listings under the Endangered Species Act, issues that potentially affect wild stocks of spring chinook salmon probably warrant immediate consideration and resolution. Mark-recapture data at Lower Granite Dam indicate that few yearling chinook salmon (Oncorhynchus tshawytscha) smolts survive to that site after release from various hatcheries. Upriver stocks of yearling spring and summer chinook exhibit pronounced losses en route to the dam. In 1989 and 1990, only about 8 to 18% of PIT-tagged representatives from McCall or Sawtooth hatchery were detected at the dam. General survival indices for these stocks indicate that perhaps only 15 to 35% of the yearlings survived to that site. This suggests these stocks may sustain as much mortality traversing this unobstructed reach of river as the general population would passing through the entire hydroelectric complex.

Annual Report, January 1, 1995--December 31, 1995 written by and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Snake River fall chinook salmon (Oncorhynchus tshawytscha) are listed as threatened under the Endangered Species Act. At present, limited data exist on the migrational characteristics of Snake River subyearling fall chinook salmon, particularly concerning the proportion of migrants that survive passage through the Snake River dams and reservoirs, the effects of flows and temperatures on survival, and the percentage of subyearlings that are guided away from turbines into collection facilities and transported. As a result, operational strategies to maximize survival have been largely based on data from studies of subyearling chinook salmon that pass through lower Columbia River dams. In 1994, the National Marine Fisheries Service and the U.S. Fish and Wildlife Service began a cooperative study to investigate migrational characteristics of subyearling fall chinook salmon in the Snake River. The primary study objectives were to (1) determine the feasibility of estimating detection and pass age survival probabilities of natural and hatchery subyearling fall chinook salmon released in the Snake River (2) investigate relationships. between detection and passage survival probabilities and travel time of subyearling fall chinook salmon and environmental influences such as flow volume and water temperature (3) monitor and evaluate dispersal of hatchery subyearling chinook salmon into nearshore rearing areas used by natural fish and (4) monitor and evaluate travel time to Lower Granite Dam, growth from release in the Snake River to recapture at Lower Granite Dam, ATPase levels of fish recaptured at Lower Granite Dam, and survival from release in the free-flowing Snake River to the tailrace of Lower Granite Dam.
