Biological science technician Andreas Raisch of the Lodi Fish and Wildlife Office prepares collection tubes for ovarian fluid samples to be taken from female Chinook salmon at the California Department of Fish and Wildlife’s Feather River Fish Hatchery, to check for any potential disease-causing agents before the eggs are incubated. Each year, the multi-agency San Joaquin River Restoration Program releases more than 200,000 juvenile spring-run Chinook from the hatchery into the San Joaquin River in an effort to restore a self-sustaining population of the endangered fish to its historic habitat.
