Upstream Migration Timing of Columbia Basin Chinook and Sockeye Salmon and Steelhead in 2012
Abstract
In 2012 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 939 spring Chinook, 390 summer Chinook, 1457 fall Chinook, 1451 steelhead, and 1601 Sockeye Salmon.
