The Zebra Mussel
Transcript of The Zebra Mussel
The zebra mussel is a small mussel that lives in freshwater. They got their name from the black and white pattern on their shells. They are about the size of a nickel and are usually found in large groups.
As an invasive species
Zebra Mussel's were originally from the lakes of southern Russia and Asia but they were accidentally introduced to a lot of different areas making them an invasive species worldwide.
Zebra Mussels have had a severe negative impact on the ecosystems they invaded. They can destroy ecosystems with "monotypic colonization", meaning they cover an area with a huge amounts of themselves, making them almost virtually impossible to remove without damaging whatever they colonize.
They have a negative impact on boat yards, power plants and water treatment plants. They can cling to water treatment pipes and clog them, making it impossible for water to pass through. They cannot be removed too easily, so the whole pipe is replaced, and that takes hard work because the pipe is underwater.
Zebra Mussels, having no natural predators, reproduce really fast. They can cover an aquatic animals home in a matter of minutes and then the animal must find somewhere else to live.
Zebra mussels now populate most of the south eastern part of Canada, including all of the great lakes.
Now, Zebra Mussels are being removed by placing screens over pipes, flushing out intake pipes with hot water or steam (temperatures above C 100° will kill zebra mussels), and injecting controlled doses of potassium
