The greatest direct impact relates to the mussel's feeding behavior. Zebra mussels are known to reach densities as high as 700,000 per square meter. Zebra mussels have also been found to have a detrimental effect on the native swan mussel population, and are responsible for drastically altering the ecology of the waters in which they live by changing fish populations. Their population steadily decreased until the 18th century. The earliest documented evidence in Europe comes from the Miocene (5.3-23 million years ago). Has distinctive 'D' shape shell, with stripes of light and dark bands of blue/brown/yellow-white bands. Zebra mussels, or more specifically Dreissena polymorpha, are a species of freshwater bivalve. They filter out algae that native species need for food and they attach to--and incapacitate--native mussels. Preferred Habitat - Zebra Mussels. Several native mussels are now listed as endangered or threatened in Vermont due to the introduction of zebra mussels. Quagga Mussels: Habitat variable; can colonize both hard and soft surfaces in freshwater, from the surface to more than 400 feet in depth. Zebra mussel, Dreissena polymorpha (Pallas, 1771), is a Ponto-Caspian species occurring in most of European waters since its invasion that started in the beginning of the 19th century (Stańczykowska, 1977).In 1980s, it further expanded its range to North America (Lewandowski, 2001).Due to its gregariousness and fouling life style, zebra mussel is regarded as an ecosystem engineer: a species . Being a temperate mussel it found the plankton-rich Lakes St. Clair and Erie to their liking. Dreissena polymorpha - Zara Brady. such as sockeye salmon. Zebra mussels attach to the shells of native mussels in great masses, effectively smothering them. Colonies have been found as far west as Oklahoma. Newly Adapted-.

Zebra Mussels Found in Aquarium Moss Balls where they live Zebra Mussels are native to the Black Sea and the Caspian Sea in Eurasia. When a native mussel has D. polymorpha attached, the native mussel loses its ability to move, feed, breath, and breed. Zebra mussels ( Dreissena polymorpha) are small, freshwater, bivalve shellfish that were likely brought to the U.S. as stowaways in the ballast water of ships. -Zebra mussels are filter feeders and process up to 1 gallon of water per day per mussel. This happens when zebra mussels take over spawning grounds and change the populations of animals that the fish eat. Zebra Mussel Fact Sheet. The Mussel Fee Sticker - also known as the Quagga Sticker - funds statewide quagga and zebra mussel prevention efforts. Native Mussel Populations - They're the ones being the most impacted by invasive mussels as their habitat and resources are being taken at a fast pace (USFWS). These mussels tend to colonize hard substrates and surfaces in high densities, with as many as tens of thousands living in a square yard. It is believed that ships originating from European ports carried the mussel in freshwater ballast thatwas discharged into Great Lake ports. The increasing shipping traffic from the Black Sea across the Danube resulted in a re-immigration. Unlike other freshwater - mussels, the zebra mussel attaches to hard surfaces using byssal threads.

Zebra mussels also can kill native U.S. mussels by attaching to their shells. The zebra mussel, Dreissena polymorpha, and quagga mussel, Dreissena bugensis, continue to colonize hard and soft substrates of the Great Lakes and are changing ecosystem function through mechanisms of ecosystem engineering (increased water clarity and reef building), fouling native mussels, high particle filtration rate with selective rejection of colonial cyanobacteria in pseudofeces . Preferred Habitat: They are typically found attached in shaded or on undersides of hard . 2001).To date, unionids have been extirpated from Lake St. Clair and nearly so in western Lake Erie.
