Quagga Found in the Ohio River

From June, 1994 (update #21)

CINCINNATI, Ohio -- A single quagga mussel (Dreissena bugensis) was collected last October from the Ohio River, according to Alex Brence and Michael Miller of the University of Cincinnati. The medium-sized mussel was 9.85 mm long and weighed 0.0909 g. Brence and Miller have not collected additional quagga mussels in this area. Since this is the first quagga mussel reported from the Ohio River, Miller said it's unclear whether quaggas have become established in the Ohio River, or whether a single mussel was transported to this location (e.g., via barge movement.).

The Zebra Mussel Update was a 4- to 8-page quarterly national newsletter published by the University of Wisconsin Sea Grant Institute from May 1990 through May 1997. The ZMU documented the spread of the zebra mussel -- an exotic nuisance mussel -- through North America's freshwater environments, especially the Great Lakes, and on efforts to control it.
