ODFW’s fish health lab has detected a novel parasite in sick rainbow trout that were raised at Klamath Falls, Rock Creek and Elk River hatcheries, Oregon Dept. of Fish and Wildlife reported Tuesday.
The detection marks the first time this parasite has been associated with disease symptoms in Oregon’s fish. |

Late last year, ODFW fish health and hatchery staff noticed increased mortality in several raceways of rainbow trout at the three hatcheries. Staff from ODFW’s fish health lab tested the fish for bacteria and viruses but did not detect any known pathogens. Hatchery staff treated the trout with two rounds of antibiotics and other supportive care but the fish did not respond. |
