Second Disease Outbreak Strikes Hot Creek Trout Hatchery in Mono County
The California Department of Fish and Wildlife (CDFW) has detected a bacterial outbreak at its Hot Creek Trout Hatchery in Mono County – the second time in 2021 that Lactococcus garvieae has been confirmed in some trout at the hatchery. Three distinct groups of trout representing about 15 percent of the hatchery’s total trout population have tested positive. CDFW has quarantined the facility, temporarily suspended fish planting and is preparing to humanely euthanize infected fish and vaccinate uninfected stocks.
