Case Study: Zebra Mussel. The zebra mussel (Dreissena polymorpha) is a prohibited invasive species, which means it is unlawful (a misdemeanor) to possess, import, purchase, transport, or introduce this species except under a permit for disposal, control, research, or education. *Established in Michigan* Researchers scrape the dock's wooden pilings for zebra mussels, counting them to track the density of the invasive species in the lake. Zebra mussel colonies can also cause economic damage to pipes and underwater structures. Current projects | Completed projects. They sometimes have dark rings but are not always easily noticeable. Invasive Species - (Dreissena polymorpha) Restricted in Michigan Zebra mussels have shells that are triangular in shape and can sit flat on the ventral side (unlike quagga mussels which have more rounded shells and cannot sit flat). Not only do they consume a great deal of the food supply in the lake, but they also attack native mussel species by sticking to them and robbing them of fresh water and food. An invasive species is one that is not native and whose introduction causes harm, or is likely to cause harm to Michigan’s economy, environment, or human health. Zebra Mussels are filter feeders that remove tons of particulates and phytoplankton from freshwater habitats they have infested. Zebra mussels by PhotoLab507. This is especially impactful in tourist areas where Zebra Mussels have spread. On average, Zebra Mussels are 1 inch long and each mussel can filter up to 1 liter of water each day. Via an excellent feature in the Grand Rapids … Native Range: Zebra mussels are native to freshwater rivers and lakes in Eastern Europe and western Asia. All week on Absolute Michigan & Michigan in Pictures we’re looking at invasive species and their impact on Michigan. Dreissenids affect industrial and municipal infrastructure, recreational water users, and they severely alter aquatic ecosystems. They disrupt the ecosystems by monotypic colonization, and damage harbors and waterways, ships and boats, and water-treatment and power plants. http://www.misin.msu.edu/tools/apps/#home, Average length of a zebra mussel is about 1 inch, Zebra shells are triangular in shape and can sit flat on the ventral side, Colors vary - shell color ranges from almost white to tan or brown in both species, usually have darker concentric rings but are not always pronounced. Zebra Mussels are an invasive species in Lake Champlain. Zebra Mussels are on Michigan's Invasive Species watch list. Water-treatment plants are most affected because the water intakes bring the microscopic, free-swimming larvae directly into the facilities. Both zebra and quagga mussels are light with dark brown markings; zebra mussels have a zigzag pattern and quagga mussels have dark concentric rings. Zebra mussels (Dreissena polymorpha) and quagga mussels (D. rostriformis bugensis) are two invasive mussel species that were transported to the Great Lakes region through ballast water discharge from ocean-going ships. In turn, this decreases food for zooplankton, increases water transparency, and leads to an accumulation of pseudofeces. The Invasive Mussel Collaborative announced today that it has released a new strategy to reduce invasive mussels and their negative impacts. Prevention is the best way to keep a water body clean of zebra mussels. They can colonize on native mussel species in groups of up to 10,000 zebra mussels which kills the native mussel. In many smaller inland lakes but also some areas of the Great Lakes where the invasive mussels have come in, native mussel species have been wiped out. Unlike the zebra mussel, quagga mussels are found to be limited to the southern Great Lakes; Lake Ontario, Michigan, Huron and Erie. Michigan Department of Natural Resources. The Great Lakes have a long history of invasive species outbreaks, starting with the introduction of the sea lamprey in Lake Ontario in the 1830s. Zebra and quagga mussels are invasive freshwater mussels that can be found throughout Ontario, Quebec, and Manitoba. Zebra mussels are found throughout all the Great Lakes, Lake St. Clair and the Mississippi river watershed. This decreases food for zoo plankton and increases water transparency. Scientists recently reported pronounced reductions in both cladophora algae and quagga mussel density in Lake Michigan’s offshore waters near Sleeping Bear Dunes National Lakeshore after an underwater project by the Invasive Mussel Collaborative. The native distribution of the species is in the Black Sea and Caspian Sea in Eurasia. are filter feeders that remove tons of particulates and phytoplankton from freshwater habitats they have infested. The quagga mussel (Dreissena rostriformis, also known as Dreissena bugensis or Dreissena rostriformis bugensis) is a species (or subspecies) of freshwater mussel, an aquatic bivalve mollusk in the family Dreissenidae.It has an average lifespan of 3 to 5 years. Zebra mussels have become an invasive species in North America, Great Britain, Ireland, Italy, Spain, and Sweden. Zebra mussels and the more recent invader quagga mussels belong to the dreissenid mussel family and many contend that they have had a more serious impact on the Great Lakes than any other invader. Since their initial discovery in 1989, zebra and quagga mussels have had … The zebra mussel had already colonized rivers and lakes across Western Europe thanks to an extensive network of canals. This leads to a less restricted range of suitable habitat than for the zebra mussel. Quagga and zebra mussels are aquatic invasive species originally native to eastern Europe. Freshwater mussels throughout the nation are already struggling, and it isn’t helping the situation when zebra mussels come in and take over their food and spawning grounds. Zebra mussels are an invasive, fingernail-sized mollusk that is native to fresh waters in Eurasia. (Dreissena polymorpha) They remove particles from the water column, increasing water clarity. zebra and quagga mussels were first found in the USA's great lakes in the late 1980s, causing great damage to their new ecostsyems. The DEEP is hoping the effort will mitigate the damage that invasive species cause to Connecticut’s lakes. Zebra mussels, an invasive species of mussel named for their striped shells, were first discovered in the Great Lakes in the late 1980s.. This connection has, is, and will continue to be a pathway for invasive species. students use invasive species … •Recent (since 2005) , near-complete replacement of zebra mussels by quagga mussels (a close relative) in the Great Lakes •Seems to be driven by ecological competition •No reports of quagga mussels in any Michigan inland lakes So…the Great Lakes case looks to be different Zebra mussel density through time Quagga mussel density through time Biologist Sonya Santavy, who found zebra mussels in 1988. The Situation: Quagga and zebra mussels are aquatic invasive species that are native to eastern Europe.The quagga mussel originated from Dnieper River drainage of Ukraine. LELAND — Northwest Lower Michigan’s national park proved a fruitful natural laboratory for an invasive species study.
