Cutthroat trout swim in a raceway at Jones Hole National Fish Hatchery in northeastern Utah. The hatchery recently completed an extensive remediation project to address New Zealand mudsnails, an aquatic invasive species, and improve infrastructure to protect fish health, strengthen biosecurity and support fisheries conservation efforts.
