A female zebra mussel begins to reproduce within 6–7 weeks of settling. [17] An adult female zebra mussel can produce 30,000 to 40,000 eggs in each reproductive cycle, and over 1 million each year. [18] Free-swimming microscopic larvae, called veligers, drift in the water for several weeks and then settle onto any hard surface they can find ...
The Dreissenidae are a family of small freshwater aquatic bivalve molluscs, commonly called mussels although not at all closely related to true mussels. The shells of these bivalves are shaped somewhat like those of true mussels, which they also resemble in attaching themselves to a hard substrate such as stone using a byssus; however, this group is more closely related to the venus clams ().

The most common types of dreissenids are Dreissena polymorpha (Zebra mussel) and Dreissena rostriformis (Quagga mussel). [14] These mussels damage both ecological systems and human infrastructure. In North America, biofouling caused by dreissenids created 267 million dollars’ worth of damage between 1989 and 2004. [ 14 ]
Before the introduction of the zebra mussel, visibility of only 10 to 15 feet (3.0 to 4.6 m) was usual, slightly decreasing as the years passed. Water clarity improved markedly in the mid-1990s with the arrival of zebra mussels, which feed on algae. The water is so clear in some areas a rocky bottom can be observed in 80 feet (24 m) of water.
The invasion of the Zebra mussel Dreissena polymorpha, (which the U.S. Fish and Wildlife Service trying to control) is one of the biggest threats to the survival of the winged mapleleaf. The Zebra mussel is an extremely invasive species and in 2000 the Zebra mussel began being a problem in the St. Croix River.
