Upstream Migration Timing of Columbia Basin Chinook Salmon, Sockeye Salmon, and Steelhead in 2011
In 2011 we sampled Sockeye and Chinook Salmon as well as steelhead at the Bonneville Dam Adult Fish Facility. Fish were measured for length and scales collected for later analysis for age and the fish were tagged with Passive Integrated Transponder (PIT) tags. These fish were tracked upstream as they passed through sites with PIT tag antennas, including fish ladders at dams, juvenile bypasses, hatcheries, weirs, as well as in-stream antennas. Total numbers of fish tracked upstream were 1045 spring Chinook, 814 summer Chinook, 1309 fall Chinook, 1377 steelhead, and 747 Sockeye Salmon.
