Dreissenid Mussel Research Priorities Workshop, Mark D. Sytsma, Stephen Phillips, Timothy D. Counihan

Center for Lakes and Reservoirs Publications and Presentations

Currently, dreissenid mussels have yet to be detected in the northwestern part of the United States and western Canada. Infestation of one of the jurisdictions within the mussel-free Pacific Northwest would likely have significant economic, soci­etal and environmental implications for the entire region. Understanding the biology and environmental tolerances of dreissenid mussels, and effectiveness of various man­agement strategies, is key to prevention.

On November 4-5, 2015, the Aquatic Bioinvasion Research and Policy Institute and the Center for Lakes and Reservoirs at Portland State University, the US Geological Survey, and the Pacific States Marine Fisheries Commission, convened a Dreissenid Mussel Research …

Center for Lakes and Reservoirs Publications and Presentations

The Oregon Invasive Species Council (OISC – “Council” is also used in this report) was established by the Oregon Legislature in 2001 [ORS 570.750, formerly 561.687]. In partnership with a broad group of state, federal and local agencies, non-profit organizations, industry representatives and individuals, the Council created and maintains the means for citizens to report sightings of invasive species and a process by which this information is forwarded to appropriate agencies; works to increase citizen engagement and awareness of invasive issues; conducts educational meetings and conferences; and, administers a trust account for funding eradication and educational projects.

In 2014, the …

Zebra And Quagga Mussel Early-Detection Monitoring In High Risk Oregon Waters 2014, Steve W. Wells, Mark D. Sytsma

Center for Lakes and Reservoirs Publications and Presentations

Zebra and quagga mussels (Dreissena polymorpha and D. rostriformis bugensis, respectively) were not detected by Oregon Department of Fish and Wildlife (ODFW) and Portland State University (PSU) during their early detection sampling in Oregon water bodies during 2014. Six high-risk Oregon water bodies were sampled for planktonic larvae and adult mussels during the August to September period. A total of 37 plankton samples were collected and over 520,000 liters of reservoir/lake water were filtered through 64-μm mesh nets during plankton sample collection. The greatest sampling effort occurred in Emigrant Lake, Lake Billy Chinook, and Prineville Reservoir but sampling also occurred …
