Three California Department of Fish and Wildlife fish hatchery facilities in the eastern Sierra and Southern California have been battling a bacterial outbreak that has affected 3.2 million fish.
Last week, after consultation with fish pathology experts and exhausting all avenues of treatment, CDFW announced that the fish, which are all trout, at the affected facilities must be euthanized in order to stop the spread of the outbreak.
The affected facilities – Mojave River Hatchery, Black Rock Hatchery and Fish Springs Hatchery – usually provide fish for stocking waterways in CDFW’s South Coast Region and Inland Deserts Region.
The euthanization of all the fish at these facilities will have a profound effect on CDFW’s ability to stock fish for anglers in those regions in the near future.
“Euthanizing our hatchery stocks was not a decision we came to lightly, but it had to be done,” said Jay Rowan environmental program manager for CDFW hatcheries. “This bacterium is resistant to all the treatment options we have available for fish. The fish losses were getting worse despite our treatments. The best option we have available that will get us back to planting fish from these hatcheries in the shortest timeline is to clear the raceways, thoroughly disinfect the facilities, and start over.”
CDFW has had the three facilities under quarantine for more than a month, while pathologists and hatchery staff treated the affected fish and researched potential options.
The outbreak of Lactococcus garvieae, which is similar to streptococcus, has been reported in cattle and poultry farms as well as fresh and saltwater fish and shellfish hatcheries around the world, but had never before been detected in fish in California.
Research of treatment options employed at trout farms in Europe and other parts of the world show there is almost no chance for successfully eliminating the bacteria from a facility without depopulation and disinfection.
Fish that are infected with Lactococcus garvieae can show symptoms including bulging eyes, lethargic or erratic swimming and increased mortality, or be asymptomatic and show no signs of infection depending on several factors including water temperature and stress.
Fish-to-human transmission of this bacteria is rare and unlikely but there are several documented instances associated with immunocompromised people consuming infected raw fish and unpasteurized milk products.
Hot Creek Hatchery in the eastern Sierra has tested negative for the bacteria and is still planting eight waters in Inyo and Mono counties. CDFW is in the process of developing a modified stocking plan to reallocate fish from central and northern California hatcheries to a small number of high angler use, easily accessible waters in geographically distinct parts of the eastern Sierra and Southern California.
For real-time updates, California anglers can refer to CDFW’s Fish Planting Schedule. This schedule is updated directly by CDFW hatchery staff. Although it contains current information, all fish plants are subject to change depending on road, water, weather and operational conditions.

LAKEPORT, Calif. – Coming out of turn four on the last lap, 17-year-old Kylie Daniels of Fort Bragg snuck under veteran driver Dane Nissen and beat him to the checkered flag by inches to claim her first Legends Car win at Lakeport Speedway Saturday during the “O’Reilly Auto Parts Day at the Races.”
Taking the lead away from points leader Donovan Cox on lap nine, Mike Collins of Lucerne chalked up his second consecutive Taco Bell Bomber main event. and Johnny Barker of Upper Lake took home the trophy in the 20 lap AAA Energy Systems Pro-4 Modified class.
In other racing action Kyle Tellstrom of Ukiah collected $1,000 for his win in the North State Modified Series race and also won the Radical Focus Midget series event.
Once again the speedway had to race with no spectators as per the Public Health officer guidelines in Lake County. However, the event was live-streamed and shown on Facebook Live with more than 8,400 people reached.
Aidan Daniels of Fort Bragg turned the quickest lap in the Legends car class (14.012), but he was involved in a crash in his heat race that prevented him from starting the feature event. Kylie Daniels was also the winner of that race. Nissen won the trophy dash.
Nissen started second row outside in the feature and ran side-by-side with Tom Summers for four laps before taking control of the race. Kylie Daniels passed Summers on lap 10 as Nissen was pulling away.
About halfway through the 30-lapper, Nissen’s car seemed to be pushing allowing Daniels to poke her nose in the hole. But Nissen’s experience kept the youngster in second until the last lap.
Then just as it looked like it was Nissen’s race, Daniels drove in low, pulled alongside Nissen and drag-raced him to the checkered flag. Daniels beat Nissen by a bumper to take the win. Summers finished third in front of David Dunlap, Ethan Imperatrice, Nick Reading and Trey Daniels.
In Taco Bell Bomber action Tim Williams set the fast time of 14.061 seconds over the 11 car field with Collins next at 14.110 and Cox turning a 14.202.
Raymond Taylor jumped out in front of pole setter Jim Kollenborn at the drop of the green flag, and as Kollenborn faded, Cox and Collins moved into second and third. Two rounds later Cox drove by Taylor for the lead with Collins following his line.
Cox ran out front for five laps before Collins took over the number one slot. The race was slowed on lap 18 when Kollenborn’s hub and spindle caught fire, eliminating him from the competition.
At the same time, both Williams and Trevor Abella retired their cars to the pits. When racing resumed it was Collins, Cox and Taylor out in front of Klinton Waite, Audrey Portlock and Kasey Horat.
Two more yellow flags flew when Portlock’s car lost power and stalled on the track. Collins continued to lead all the way to the checkers followed by Cox, Taylor, Waite, Horat and Portlock.
Heat wins went to Waite and Collins. Cox won the trophy dash.
Mike Peterson set the fast time (12.767) in the Pro-4 Modifieds, almost a half a second faster than second runner Ron Portlock (13.235.) But Peterson’s car developed problems that kept him from running the main event. Wil Roberton also dropped out early as did Portlock.
This made easy pickings for Barker who led every lap for the win. Bud Anderson finished second with Rick Jelton third and Wade Eldrege fourth. Peterson won the heat race and Anderson captured the trophy dash.
Racing resumes at the Lakeport Speedway next Saturday, July 25, with the second appearance of the Legends of the Pacific. Also for the first time will be the local late models. Rounding out the card are the Taco Bell Bombers and the NCRA modifieds.
