USGS studies zebra mussel control with ionic copper

The USGS is studying zebra mussel control in Lake Minnetonka, Minnesota. The project is a collaboration with the University of Minnesota Aquatic Invasive Species Research Center. If successful, the treatment could provide a blueprint for protecting other lakes infested with zebra mussels.

Copper ion generator cons outweigh pros

An independent study for the Bureau of Reclamation found that unexpected electrical problems and rapid deterioration of anodes compromised a copper ion generator under real world conditions. As a result, the installation significantly underperformed expectations set by the manufacturer’s manual.

Four Zebra Mussel Myths and Where They Went Wrong

Like all fearsome creatures, zebra mussels come with their own set of myths. These are the stories we tell ourselves about zebra mussels, usually in preparation to battle them. They are not necessarily false stories, but they are not always true, either. Knowing the difference is critical to developing efficient and cost-effective zebra mussel management strategies.

Zebra Mussel Myth #2: Zebra Mussels Must Be Eradicated

Once zebra mussels or quagga mussels are widely distributed throughout a large lake, there is little hope for eradication with currently available methods. In these cases, it is important to let go of the myth that invasive mussels must be eradicated. This myth feeds a common, but mistaken, perception that control measures are costly and futile once invasive mussels are firmly established.

Zebra Mussel Myth #3: Zebra Mussel Control Systems Should Be Engineered

Good engineering is absolutely vital for the smooth operation of any water treatment plant or power generation facility, but time and zebra mussels wait for no one — not even engineers. Developing and installing new technologies takes time — sometimes years. Without immediate control measures in place, zebra mussels have that much more time to wreak havoc.
