What You'll Learn
Zebra mussels are an invasive species
Zebra mussels (Dreissena polymorpha) are small, freshwater mussels, native to the lakes of southern Russia and Ukraine. They are aquatic bivalve mollusks, typically growing to around the size of a fingernail, and are named after the striped pattern commonly found on their shells.
In North America, zebra mussels have spread throughout the Eastern, Midwestern, and Southern United States, invading major water systems such as the Great Lakes, Hudson River, and Mississippi River. They have also been found in California, Texas, Colorado, Utah, and Nevada. Their feeding habits can drastically impact infested lakes and rivers. As filter feeders, they can quickly clear the water of floating particles, disrupting local food webs and increasing water clarity, making it easier for visual predators to hunt. They also attach to and incapacitate native mussels, leading to their decline.
Zebra mussels have caused substantial economic costs, particularly for water treatment and power plants. They cling to pipes, clogging them and requiring expensive removal. Water companies have reported significant problems, with the removal of zebra mussels from treatment plants costing hundreds of thousands of pounds annually. Additionally, zebra mussels can attach to boat hulls, increasing drag and affecting steering, which can lead to engine malfunctions.
To control the spread of zebra mussels, prevention is crucial. Boaters are advised to drain and wash their boats, motors, and equipment before leaving a potentially infested lake or river. In some cases, chemicals or bacterial toxins that are deadly to zebra mussels but relatively harmless to other organisms may be used for control.

They are native to the Caspian Sea region
Zebra mussels (Dreissena polymorpha) are native to the Caspian Sea region in southern Russia and Ukraine. They are small freshwater mussels, with a maximum length of around 50mm (2 inches) and a distinct, flat-bottomed 'D' shape to their shells. Their name comes from the striped pattern commonly seen on their shells, although not all zebra mussels have this feature.
Zebra mussels are an invasive species and have spread beyond their native range into Europe and North America. They were first reported outside of their native range in Hungary in 1794 and subsequently in the Netherlands, Great Britain, Ireland, Italy, Spain, Sweden, and North America. In North America, zebra mussels were first detected in the Great Lakes in the 1980s and have since spread throughout the Eastern, Midwestern, and Southern United States, as well as into Canada.
The spread of zebra mussels is often facilitated by human activity, particularly the discharge of ballast water from large ships. Once established in a water body, zebra mussels are difficult to remove, and they can have significant negative impacts on the environment and infrastructure. They are filter feeders that can outcompete native species for food, such as plankton, and they attach themselves to and incapacitate native mussels. This can lead to shifts in local food webs and the extinction of native species.
Zebra mussels also cause economic damage by clogging pipes and intake structures in power stations and water treatment plants. The removal of zebra mussels from these facilities can be costly, and their presence can disrupt ecosystems and damage harbors, waterways, and watercraft. In Canada, zebra mussels are listed as one of the six prohibited species under the federal Aquatic Invasive Species Regulations, and efforts are made to prevent their spread through contaminated watercraft and aquarium products.
Overall, while zebra mussels are native to the Caspian Sea region, they have become an invasive species in many parts of the world, with far-reaching ecological and economic impacts.

They have a history of invasion
Zebra mussels (Dreissena polymorpha) are native to fresh and brackish waters in the Caspian Sea region of southeastern Europe. They are, however, highly invasive and have a long history of invading new territories. They were first described in 1769 by German zoologist Peter Simon Pallas in the Ural, Volga, and Dnieper Rivers. They were likely transported as larvae or young adults inside the ballast tanks of large ocean-going ships originating from Europe.
Zebra mussels were first reported in Ireland in 1997, but they probably arrived earlier in 1994 or before that. They were first identified near Lough Derg and have since spread through much of the River Shannon and its adjacent waters. In Great Britain, zebra mussels were first reported in Cambridgeshire in the 1820s, in London in 1824, and in a canal near Edinburgh in 1834. They were also reported in the Netherlands in 1827, the Czech Republic in 1893, Sweden in 1920, and Italy in 1973.
In North America, zebra mussels were first detected in the Great Lakes in 1988, likely transported from Europe in the ballast water of large ships. They have since spread throughout the Eastern, Midwestern, and Southern United States, including the Mississippi and St. Croix Rivers. They have also been found in Texas, Colorado, Utah, Nevada, and California. In 2009, zebra mussels were found in Laurel Lake in Massachusetts and Pelican Lake in Minnesota, the first sighting in the Red River Basin. Despite efforts to eradicate them, they continue to spread, impacting local ecosystems and water treatment facilities.
Zebra mussels are prolific breeders and can attach to both hard and soft surfaces in freshwater ways. They are highly efficient filter feeders, quickly clearing the water of floating particles, which can cause shifts in local food webs and impact native species. They also attach to and incapacitate native mussels, boats, and water intake structures, leading to ecological and economic problems. Their invasion has resulted in increased maintenance costs for water treatment and power plants.

They cause ecological problems
Zebra mussels (Dreissena polymorpha) are an invasive species that have spread across many countries and continents, including North America, Great Britain, Ireland, Italy, Spain, and Sweden, and the Czech Republic. They are native to the lakes of southern Russia and Ukraine but have become one of the world's most invasive aquatic species due to their accidental introduction to other regions.
Zebra mussels cause ecological problems by disrupting local ecosystems and damaging infrastructure. As filter feeders, they efficiently siphon plankton from the water, depriving native species that depend on it for food. They also increase water clarity, making it easier for visual predators to hunt and altering the dynamics of local food webs.
Zebra mussels have a rapid reproduction rate, enabling them to quickly overwhelm a water system. They can survive out of water for several days or weeks under certain conditions, allowing them to spread to new water bodies via human transportation or natural water currents. Once established, zebra mussels are challenging to eradicate, and prevention becomes crucial to controlling their spread.
The economic impact of zebra mussels is significant. Power plants and water treatment facilities face high costs for removing and preventing zebra mussel infestations. Additionally, zebra mussels can damage harbors, waterways, ships, and boats, as well as other water-related equipment, resulting in further economic burdens.
The invasion of zebra mussels has led to changes in the fishing industry, as seen in Salford Quays. Their presence can also contribute to the growth of toxic cyanobacteria, posing ecological and environmental challenges. The negative consequences of zebra mussels on aquatic ecosystems highlight the importance of prevention and management strategies to mitigate their impact.

They are hard to remove once established
Zebra mussels (Dreissena polymorpha) are an invasive species that can be challenging to eradicate once they have become established in a water body. They are native to the lakes of southern Russia and Ukraine, but have been accidentally introduced to other regions, including North America, Great Britain, Ireland, Italy, Spain, and Sweden.
Zebra mussels are small, freshwater, bivalve shellfish that can attach themselves to hard surfaces using root-like threads of protein called "byssal threads." They are highly efficient filter feeders, siphoning particles of plankton and algae from the water. This can have a significant impact on the local food web, as it reduces the availability of food for native species that depend on plankton and algae.
The microscopic larvae of zebra mussels, known as veligers, are easily transported in ballast water, boats, and other water-based equipment, allowing them to spread rapidly to new water bodies. Once they have established a population in a river or lake, they can be challenging to remove. Prevention and early detection are crucial in managing the spread of zebra mussels.
Efforts to eradicate zebra mussels from infested water bodies have met with varying degrees of success. For example, aggressive attempts to eradicate them from Manitoba's Lake Winnipeg in 2014 were unsuccessful, and new contamination was discovered outside treated areas in 2015. The cost of removing zebra mussels from clogged water intakes and infrastructure can be significant, with water treatment plants bearing the brunt of the impact.
The invasive nature of zebra mussels and their ability to rapidly colonize new habitats make them challenging to remove once they have become established. Their impact on ecosystems and infrastructure underscores the importance of prevention and early detection in managing their spread.
