PTAGIS - Development of Large PIT-Tag Antennas to Estimate Migration Timing and Survival for Adult Salmonids near Pile Dikes in the Columbia River Estuary
We continued research and development of a passive PIT-tag detection system along a pile dike in the estuary (rkm 70). Target fish for this system are returning adult salmonids, whose detection in the mid-estuary can be compared with subsequent detections at upstream dams to determine timing and survival during the …
