Transportation of Juvenile Salmonids on the Columbia and Snake Rivers, 2003: Final Adult Returns for Wild Yearling Chinook Salmon Migrating in 2000

Since 1995, the National Marine Fisheries Service has evaluated transportation of Snake River spring/summer chinook salmon smolts. Beginning in 2002, spring chinook salmon transportation was also evaluated from McNary Dam using fish PIT-tagged at upper Columbia River hatcheries. From March to August 2003, we recovered age-3-ocean spring/summer chinook salmon adults from smolts tagged in 2000, completing adult returns from that study year. 2004 Contract no.
