New Technology to Support Culturing of Freshwater Mussels for Research and Restoration

Freshwater mussels are one of the most critically imperiled groups of organisms worldwide. Encouraging mussel reproduction in a controlled setting has become an area of interest due to their widespread population declines and regional extinctions (Williams et al., 1993; Lydeard et al., 2004; Strayer et al., 2004; Haag 2012; Lopes-Lima et al., 2017). With constantly evolving techniques, rearing...

Science Partnership between USGS and Confederated Tribes of the Umatilla Indian Reservation to Support Conservation of Freshwater Mussels

Western Pearlshell ( Margaritifera falcata ) is a native mussel species of conservation concern in the Pacific Northwest region of North America. This species is of cultural importance to the Confederated Tribes of the Umatilla Indian Reservation (CTUIR). The current project is a collaboration between the USGS Columbia Environmental Research Center (CERC), the CTUIR, and USFWS to better understand...

Physical Stream Dynamics and Native Mussel Habitats

Freshwater mussel conservation efforts depend on identifying habitat characteristics that are suitable for mussel reintroduction and restoration. CERC scientists are conducting research to understand how physical habitat dynamics affect the distribution of mussels and suitable habitat in streams and rivers.

Pallid Sturgeon Early Life

CERC biologists focus on improving understanding of biomechanics of eggs, free embryos, and larvae through direct observation and measurement. An improved understanding of biomechanics – how biotic conditions and processes interact with physical processes to result in changes in survival – is necessary to create quantitative links between management actions and population-level results.

An Evaluation the Chronic Toxicity of Metals in Water and Sediment to the Unionid Mussel, Fatmucket (Lampsilis siliquoidea), in Exposures Representing Conditions in the Tri-States Mining District

The Tri-State Mining District (TSMD) is a large (about 500 sq. mi.) historical lead and zinc mining area that includes portions of Kansas, Missouri and Oklahoma. The TSMD yielded about 460 million tons of ore between 1885 and 1970, resulting in contamination of surface water, groundwater, sediments, and soils in the Spring River and Neosho River basins by lead, zinc, and other heavy metals.
