The Feather River Fish Hatchery in Oroville has wrapped up its tagging operations for adult spring-run Chinook salmon. According to the California Department of Water Resources, around 7,919 salmon were tagged this season. Officials say the tagging helps track the success of hatchery operations and improve fish population management. The DWR and the California Department of Fish and Wildlife also continued thiamine treatments to address vitamin deficiencies in Chinook salmon, enhancing their survival from egg to juvenile. The California Department of Water Resources reported that more than 17,000 spring-run Chinook salmon returned to spawn this year, marking the best return since 2013. Despite recent drought impacts, the hatchery continues to meet and exceed production goals.
