The California Department of Fish and Wildlife (CDFW) plans to inject 350,000 Chinook salmon eggs into the North Yuba River this fall as the state government looks for new ways to help struggling salmon populations recover. This is the second year CDFW has taken this approach, collecting eggs fertilized at the Feather River Fish Hatchery in Oroville and then hydraulically injecting them into the river’s gravel substrate in November. … Salmon populations have struggled in California rivers as they face rising temperatures and fish passage blockages like dams.
