A bacterial outbreak at two state hatcheries is forcing the California Department of Fish and Wildlife to eat about 350,000 rainbow trout, which could affect catches in some of the state’s waterways this season. this summer.
Two Fish and Wildlife hatcheries in the Eastern Sierra have been battling an outbreak of a naturally occurring bacteria, Lactococcus petauri, since it was first detected in April, according to a release from the agency. this office. But this week, staff at Black Rock and Fish Springs hatcheries determined that about 350,000 infected rainbow trout showed signs of the disease and must be eaten.
These two facilities often stock recreational fishing waterways in Imperial, Inyo, Mono, Riverside and San Bernardino counties, so availability in these areas will likely be impacted. However, Fish and Wildlife officials are working to contract outside suppliers to transport in other warehouses so as not to significantly affect catch opportunities, the statement said.
The statement said officials are hoping to ratify the new contract by July so that additional seed stocks can be added to the waterways shortly after, as well as additional state hatcheries. .
“This loss is a huge disappointment, but we have been prepared for this possibility and are doing all we can to ensure there continue to be opportunities for fishing for the public,” said Russell Black, director of the program. Fisheries and Wildlife Monitor, said in a statement. “Fish from private contractors and herds from uninfected hatcheries will help close the gap while we work to vaccinate the remaining flocks at the affected facilities.”
The agency is planning to use two different fish vaccines, developed by UC Davis, at affected hatcheries.
The state agency said the transmission of the bacteria that causes rainbow trout from fish to humans was “rare and unlikely” but reminded people to always cook any fish caught to an internal temperature of 145 poison.
This bacterium, Lactococcus petauri, is usually spread through the movement of fish or eggs, the statement said. Fish and Wildlife pathologists believe it may have been introduced into the hatchery by birds that picked it up from an unknown source in the environment.
