Study goal: Use radio telemetry to monitor and evaluate passage
of adult salmon and steelhead in Columbia and
Snake rivers
Methods
1. Collect and tag fish at Bonneville Dam.
2. Release tagged fish downstream
and upstream of Bonneville Dam.

Use of PIT tags
1999: Trial use of archival Data Storage Transmitters (DSTS).
fish tagged at Ice Harbor Dam and retrieved at
Lower Granite Dam using Sort-by-Code
2000: Selecting for known-source fish at Bonneville Dam
for evaluations of homing ability.
2002: Double tagged (radio and PIT) fish used to evaluate
fishway PIT tag detectors and lost tags.
2002: Develop methods to interpret fishway PIT tag detections
to evaluate adult salmon and steelhead passage at dams.
Objectives
Summarize homing and straying rates for known-source adults
Identify fates and distribution of known-source fish
that did not home or stray
• Mainstem harvest
• Unknown fate

Conclusions: Chinook Salmon
Estimates of homing, straying, harvest and unknown fate:
Chinook
Homing
~ 81.2%
Straying
Harvest
Unknown
~ 1.9%
~ 9.2%
~ 7.8%
Homing relatively high for Yakima River, low for Wind River
Large differences in proportions of unaccounted for fish
between stocks, mostly in 2001: low harvest of summer chinook
Barged fish home at lower rates, stray at higher rates and
tended to have larger proportions with unknown fate
Conclusions: Steelhead
Estimates of homing, straying, harvest and unknown fate:
Homing
Steelhead
~ 83.9%
Straying
Harvest
Unknown
~ 6.9%
~ 11.2%
~ 10.5%
Homing generally consistent between stocks
Upper Columbia stocks harvested at higher rates than Snake
River stocks
Barged fish home at lower rates, stray at higher rates and
tended to have larger proportions with unknown fate
Methods Obj. 2. Build and install PIT detectors.
Instream PIT detectors are based on 23 mm, 12 mm and 12 mm extended read range
134 kHz ISO tags.
Components:
Open coil inductor loops composed of multi-strand wire strung through 4 in. diameter PVC pipe.
Multiple loops can be combined to cover stream widths.
Largest units tested to date were 6 x 2 m.
Multiplexor.
