Upstream Migration Timing of Columbia Basin Chinook and Sockeye Salmon and Steelhead in 2013
In 2013 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 1008 spring Chinook, 937 summer Chinook, 1461 fall Chinook, and 772 Sockeye Salmon, and 1276 steelhead.
