Quagga Mussels

Environmental organizations from the United States and Canada have teamed up each year, as part of the Cooperative Science and Monitoring Initiative (CSMI) program, to assess conditions in one of the five Great Lakes. . Each year, the survey focuses on a series of research areas, such as phosphorus and nitrogen input and movement through the food web, phytoplankton and zooplankton populations, and...

USGS scientists worked with the National Oceanic and Atmospheric Administration (NOAA) to monitor growth of invasive zebra mussels ( Dreissena polymorpha ) in Lake Ontario with the goal of improving understanding on the effects these mussels have on the Lake food web.

The Invasive Mussel Collaborative was formed in 2014 to advance scientifically sound technology for invasive mussel control to produce measurable ecological and economic benefits in the Great Lakes. A broad membership base of states, provinces, tribal and other entities and a well-organized communication network facilitates the exchange of information between scientists, managers and stakeholders...

Invasive zebra and quagga mussels ( Dreissena polymorpha and D. rostriformis bugensis , respectively) are causing significant ecological and economic impacts and the scope of these impacts increases as they continue to spread across North America. The USGS conducts science to inform management actions for controlling and mitigating the impacts of invasive mussels. Studies include evaluation and...
