Genidaqs recently partnered with the U.S. Geological Survey and fellow collaborators on an innovative study exploring how different eDNA sampling techniques perform in detecting fish communities—especially the elusive longfin smelt—in restored tidal wetlands of the San Francisco Bay Estuary. Traditional fish sampling methods were compared with two eDNA-based approaches: standard filtration using Sterivex™ filters and […]

eDNA Testing for Invasive Golden Mussel (Limnoperna fortunei)

The removal of four dams along the Klamath River represents a unique opportunity to study the impacts of large-scale dam removal on river ecology. To establish an invaluable genetic baseline, the study team (Genidaqs, RES) collected and preserved over 400 DNA and RNA samples from locations across the Klamath River before dam removal.

Native salmonids (Rainbow/steelhead trout, Bull Trout, Dolly Varden) populations in the upper Skagit River have a complex evolutionary past shaped by geology, hydrology, and human actions. In our latest research study funded by City Light, we’re using genomic tools to unravel the phylogenetic biogeography of Rainbow and Bull Trout in the upper Skagit River basin.
