Why are quagga mussels a problem?

Why is it a problem? Quagga are prodigious water filterers, thus removing substantial amounts of phytoplankton from the water and altering the food web. Quagga mussels clog water intake pipes and underwater screens much like zebra mussels. Quagga mussels damage boats, power plants, and harbors.

Damaging Ecosystems Quagga and zebra mussels damage the ecosystems they invade. They feed by filtering water and removing large amounts of food, effectively starving native species in infested rivers and lakes.

Are quagga mussels dangerous?

Ecological problems also result from mussel invasions. Zebra and quagga mussels can kill native freshwater mussels in two ways: (1) attachment to the shells of native species can kill them, and (2) these invasive species can outcompete native mussels and other filter feeding invertebrates for food.

Why are zebra mussels bad?

In spite of their small size (often no bigger than a penny) zebra mussels cause far-reaching damage to water structures and native ecosystems. They also negatively impact aquatic ecosystems by harming native organisms. In huge numbers, they out-compete other filter feeders, starving them.
