USGS Scientist Travels to Norway in Collaborative Fish Health Effort:  On December 11, 2019, USGS scientist Dr. Maureen Purcell traveled to Oslo Norway to serve as the external examiner for a Ph.D. dissertation at the Norwegian Life Sciences University (NMBU). The dissertation focuses on characterization and pathogenensis of Piscine orthoreovirus (PRV). PRV is present in North America and there is debate as to the risk posed by this virus to Pacific salmon. Additionally, Dr. Purcell will met with other Norwegian scientists that conduct world class research on infectious diseases of cultured and wild finfish. The strengthens collaborative ties with Norwegian research institutions.

USGS at Lamprey Information Exchange Workshop: On December 12-13, USGS scientists Marty Liedtke and Lisa Weiland attended the 3rd Annual Lamprey Information Exchange at the Water Resources Education Center in Vancouver, WA. The two-day workshop allowed participants to exchange the newest information on lamprey. Weiland presented a speed talk on dewatering approaches to protect larval lamprey.

New Publications

New Publication Describes the Development of an Environmental DNA (eDNA) Assay for Detection of Redside Shiner:  Redside shiner are indigenous throughout much of western North America, but their range has expanded through illegal releases. Their introductions into non-native habitats negatively impacts native fishes via predation on eggs and fry and competition for food and space. Aquatic environmental DNA (eDNA) offers an economical and highly sensitive alternative method for detecting species and could be used for redside shiner distributions. In a recent publication, scientists from USGS Western Fisheries Research Center developed an eDNA assay for detection of redside shiner. The assay provides resource managers with an effective means for surveying and monitoring redside shiner populations.
