Quagga Mussels Invading Great Lakes

Although the zebra mussel is better known to the public, over the past decade it has largely been displaced in Lake Michigan by the quagga mussel, according to an article in the online magazine Michigan Today. Each quagga and zebra mussel filters about a quart of water a day—and there are billions of them in Lake Michigan alone. The result is startlingly clear water that delights recreational boaters but disturbs scientists because the water has been stripped of life-supporting algae. In Lake Huron, this has lead to less abundant whitefish and contributed to the decimation of the alewife population, which in turn has led to a drop in Chinook numbers.
