Description:

In 2007, the National Marine Fisheries Service and Real Time Research, Inc. collaborated to recover passive integrated transponder (PIT) tags from juvenile Pacific salmonids Oncorhynchus spp. on avian colonies throughout the Columbia River Basin (CRB). Over 63,000 PIT tag codes with no previous detection on an avian colony were recovered. Of this total, over 42,000 were from fish migrating in 2007. Avian predators consumed a minimum of 3.0% of the 1.4 million PIT-tagged salmonids released into the CRB for migration during 2007. Approximately 90% of those fish were consumed either by Caspian terns Sterna caspia or double-crested cormorants Plwlacrocorax auritas.
