Why can’t we kill zebra mussels?
Zebra mussels also cling to surfaces, and can clog water supply pipes at power plants and other water supply infrastructure. They only had a few weeks before the water would be frozen, and the mussels would be difficult to detect and ready to reproduce in the spring.
What animals eat zebra mussels?

Several other fish species are listed as potential predators of zebra mussels because of their historic consumption of other native molluscs.
How much does it cost to get rid of zebra mussels?

Why are zebra mussels so successful in the US?
Zebra mussels are very successful invaders because they live and feed in many different aquatic habitats, breed prolifically (each female produces 1 million eggs per year), and have both a planktonic larval stage and an attached adult stage.
Were zebra mussels intentionally transported to us?
In the case of zebra and quagga mussels, the introduction to the U.S. was accidental. They were probably brought to the Great Lakes as stowaways in the ballast water of a cargo ship that came from Europe or Asia. Ballast water is taken aboard to maintain stability and is discharged when new cargo is added to the ship.
What makes a successful invasive species?
Invasive species are often successful in their new ecosystems because they can reproduce and grow rapidly or because their new environment lacks any natural predators or pests. As a result, invasive species can threaten native species and disrupt important ecosystem processes.
What are humans doing to stop zebra mussels?
What you can do to stop the spread of the invasive zebra mussel: Inspect boat, trailer, and other recreational equipment that have been in contact with water. Remove all mud, plants, or animals.
