Why is the quagga mussel 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.
How do quagga mussel affect the environment?
The filter-feeding quagga mussel has a high filtering rate for its size, and coupled with its high abundance, has a significant impact in invaded ecosystems, like the Great Lakes. By filtering phytoplankton and other materials from lake water, quagga mussels alter both lake habitat and the food web.
How are quagga and zebra mussels a threat to California?
These two invasive, freshwater Eurasian mussels—zebra mussels and quagga mussels — could have a profound impact on California’s lakes and water distribution systems. Clogging of pipe by mussels. They attach themselves to water conveyance systems — pumps, pipes, dams, aqueducts, and fish hatcheries — and proliferate.
Do quagga mussels have predators?

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.
Are zebra mussels bad for humans?
EAST LANSING, Mich. Inland lakes in Michigan that have been invaded by zebra mussels, an exotic species that has plagued bodies of water in several states since the 1980s, have higher levels of algae that produce a toxin that can be harmful to humans and animals, according to a Michigan State University researcher.

Can zebra mussels kill fish?
Zebra mussels are possibly the most familiar of these. Since then, the mussels have spread throughout the lake and their effects have been well chronicled. They kill native mussels; coat surfaces with razor-sharp shells; foul anchor chains; block water intake pipes; and steal plankton and other food from native fish.
Do zebra mussels make water clearer?
Water clarity The rate of reproduction and spread of zebra mussels make them efficient cleaners of Great Lakes water, but whether that’s a positive or negative thing depends on who you’re asking. “Some people do think the water clarity is a benefit,” Waller said.

Zebra mussels were discovered on Pelican Lake in 2009 and some of those found were determined to be one or two years old because of their size. Zebra mussels have a 3 to 4 year life cycle in our area and go dormant at less than 55 degrees. They cannot survive freezing temperatures.
