Age and Length Composition of Columbia Basin Chinook, Sockeye, and Steelhead at Bonneville Dam in 2008: WEEKLY UPDATE |
updated every Tuesday |
John Whiteaker, Jeffrey K. Fryer
Age and length composition of representative samples of adult Columbia
Basin chinook (Oncorhynchus tshawytscha), sockeye (O. nerka),
and steelhead salmon (O. mykiss). Gathered results contribute
to an ongoing database for age class structure of Columbia Basin salmon
populations. Ω |
| Procedures
for Estimating Tag Loss Rate and Spawning Escapement in a Mark-Recapture
Study of Metolius River Kokanee Oncorhynchus nerka
|
4 Aug 2008 |
Peter F. Galbreath, Saang-Yoon Hyun
Mark-Recapture/Resight
procedures were used to estimate the 2007 spawning escapement of kokanee
Oncorhynchus nerka migrating from Lake Billy Chinook into
the Metolius River, Jefferson County, Oregon. An initial analysis
of data, which included an adjustment for a presumed 25% tag loss
rate (without confidence limits), provided an escapement estimate
of 101,854 ± 11,151 (±10.9%; 95% confidence interval). |
| Influence of landscape on
resident and anadromous life history types of Oncorhynchus mykiss
|
2008 |
Shawn Narum, et al
Landscape
features can significantly influence genetic and life history diverstiy
of rainbow/steelhead trout, Oncorhynchus mykiss. In this
study, heterozygosity of 21 populations of O. mykiss from
the Pacific Northwest, USA, was significantly negatively correlated
with features such as elevation (P=0.0023), upstream distance
(P=0.0129), and precipitation (P=0.0331), and positively
correlated with temperature (P=0.0123). |
| A GIS Analysis of Climate Change and Snowpack on Columbia Basin Tribal Lands
|
27 May 2008 |
David Graves
A GIS-based analysis to better anticipate changes to snowpack on tribal ceded areas in the Columbia Basin.
This analysis includes the use of contemporary climate data and
projections of 21st century climate change. Contemporary data were
examined to determine the extent of areas near or just above the
current mean winter freezing level, which may transition from snow-dominated
to rain-dominated regimes with moderate warming. A snowpack model
was constructed and implemented at monthly time steps to simulate
precipitation, snowpack, and snowmelt over a distributed area during
future climate scenarios. |

Douglas R. Hatch (primary investigator) et al.
The annual report of a field study to investigate the reproductive
success of hatchery, wild, and artificially reconditioned kelt steelhead.

loci to determine parentage. |
| Age
and Length Composition of Columbia Basin Chinook and Sockeye Salmon and
Steelhead at Bonneville Dam in 2007
|
3 April 2008 |
John Whiteaker, Jeffrey K. Fryer
A field study at Bonneville Dam in 2007 to assess the age, length-at-age
and stock composition of adult Pacific salmon migrating up the Columbia
River. These data were then used to predict the 2007 Chinook salmon
run. Adult spring, summer and fall Chinook salmon (Oncorhynchus
tshawytscha), sockeye salmon (O. nerka) and summer-run
steelhead (O. mykiss) were collected, sampled for scales
and additional biological data, revived and released. |
| Use
of PIT tags to determine upstream migratory timing and survival of Columbia
Basin sockeye salmon in 2007 |
31 Jan 2008 |
Jeffrey K. Fryer
A total of 509 sockeye salmon, Oncorhynchus nerka, were PIT-tagged
at Bonneville Dam in 2007 and tracked upstream using detections at
mainstem dam fish ladders. Based on these detections, upstream survival
steadily declined as the migration progressed; Bonneville-Rock Island
survival declined from over 74% for sockeye salmon passing Bonneville
Dam during June to less then 68% during the first two weeks of July.
There was also a significant linear relationship between decreasing
survival and increasing water temperature. The estimated stock composition
of sockeye passing Bonneville Dam was 85.3% Okanogan and 14.7% Wenatchee. |
| Estimation of mid-Columbia summer
Chinook salmon escapement and age composition using PIT tags in 2007 |
15 Jan 2008 |
Jeffrey K. Fryer
In 2007, a total of 470 summer Chinook salmon (Oncorhynchus tshawytscha)
were PIT tagged at Bonneville Dam between June 16 and July 13. An
additional 763 spring Chinook salmon were PIT tagged between April
24 and June 15, while 194 fall Chinook were PIT tagged between September
13 and October 12. After adding previously tagged fish, and subtracting
fish that likely shed PIT tags, a total of 764 spring Chinook, 470
summer Chinook, and 194 fall Chinook were tracked upstream. |

| Altered Flood Control,
Climate Change, And Rebuilding Pacific Northwest Salmon Stocks |
Spring 2006 |
Kyle Dittmer
Moving the mainstem Columbia and Snake Rivers back toward natural
conditions will promote integrated ecosystems. Altered flood control
operations, plus earlier reservoir refill, creates a more natural
peaking flow regime that is more harmonious with the salmon's life
cycle than current Federal operations can provide, while still protecting
down river communities. Altered flood control can achieve immediate
benefits to depressed salmon populations and may be a more timely
measure while the region debates the issue of bypassing the four Lower
Snake dams. |

| A Distinctive Microsatellite
Locus That Differentiates Ocean-Type from Stream-Type Chinook Salmon
in the Interior Columbia River Basin |
20 January 2004 |
Shawn R. Narum, Madison S. Powell,
André J. Talbot
Chinook salmon Oncorhynchus tshawytscha display two life
history strategies that are referred to as ocean type and stream type.
Ocean-type Chinook salmon typically differ from stream-type fish in
juvenile migration timing, adult spawning location, and run timing.
Spatial and temporal separation during spawning can lead to reproductive
isolation and genetic divergence between the two life history strategies. |
