Description:

In 2003 and 2004, we continued to detect juvenile Pacific salmonids Oncorhynchus spp. implanted with passive integrated transponder (PIT) tags using surface pair-trawls fitted with PIT-tag detection antennas. Two areas in the Columbia River estuary were sampled. The primary sampling site was an upper, freshwater reach

near Jones Beach, at river kilometer (rkm) 61-83. A secondary site (sampled in 2004 only) was in the brackish-water portion of the lower estuary (rkm 8-24).
