Spatial and temporal survey of waterborne myxozoan parasites in the Lake Sammamish watershed, Washington, from 2019 - 2020

There is a fundamental knowledge gap on the distribution, prevalence, intensity, and ecology of salmonid myxozoan parasites in the Lake Sammamish watershed, Washington. To address this knowledge gap, we tested water samples for Ceratonova shasta, Parvicapsula minibicornis and Tetracapsuloides bryosalmonae DNA from 84 sites distributed throughout the Lake Sammamish watershed in fall 2019 and 74 sites in spring 2020. Our surveillance identified zones with high waterborne parasite loads and provides a proof of concept for this approach that could be expanded throughout the larger Lake Washington watershed.
