Chang, T. J., and M. A. Hoover, 1996. Development of a Mechanical Device for Zebra Mussel Control, Ohio University Abstract from The Sixth International Zebra Mussel and Other Aquatic Nuisance Species Conference, Dearborn, Michigan, March 1996 Development of a Mechanical Device for Zebra Mussel ControlThe oxygen supply is essential for zebra mussels to maintain active. Laboratory tests showed that the mortality rate of zebra mussels is about three times higher, when they are placed under vacuum, than its counterpart when exposed to air. It is the absence of dissolved oxygen, not the air exposure, that plays the key role in the elimination of zebra mussels. Therefore, a reduction of dissolved oxygen in the water will have an adverse effect on zebra mussels activeness to prevent them from attaching to piping systems. A mechanical device was proposed to reduce the dissolved oxygen of water for zebra mussel control. The device consisting of a vacuum tank with water circulation system was constructed in the laboratory for testing. Preliminary results that it is a promising mechanical method for controlling zebra mussels.
