Upstream Migration Timing of Columbia Basin Chinook and Sockeye Salmon and Steelhead in 2014

Mar 31, 2016


In 2014, 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 1508 spring Chinook, 962 summer Chinook, 1375 fall Chinook, 1400 Sockeye Salmon, and 1717 steelhead.
