Chinook Salmon Increase with Millions of Offspring

Endangered Winter-run Chinook Salmon Increase with Millions of Offspring Headed to Sea

Biologists have estimated that almost 3.8 million juvenile winter-run Chinook salmon headed down the Sacramento River toward the ocean this year. This is the most offspring in a decade for the highly endangered population.

Typically about 80 percent of the outgoing juveniles have headed for the ocean by this time of year. This year’s total thus far is the most since 2009, when about 5 million juveniles traveled downriver.

The rebounding numbers of winter-run Chinook salmon reflect the critical help of a conservation fish hatchery and balanced water management. More favorable ocean conditions also benefited the parents of this year’s surging crop of juveniles, biologists say. About 8,000 adult fish returned to the Sacramento River to spawn earlier this year, the most since 2006.
