How did zebra mussels get to Lake Michigan?
The zebra mussel, Dreissena polymorpha, is believed to have arrived in North America as a freshwater ballast stowaway in commercial vessels from Europe sometime around 1986. The mussel was first discovered in the Great Lakes in Lake St. Clair in June 1988.
How do zebra mussels affect Lake Michigan?
With billions of them inhabiting Lake Michigan, it doesn’t take long to filter a large body of water. Zebra mussels clog intake pipes at water treatment facilities and power plants. They filter valuable nutrients from lakes and rivers. Because they eat plankton, they disrupt food chains and displace native species.
How are the zebra mussels affecting food chains in Lake Michigan?
Pothoven said invasive mussels reduce the productivity of offshore regions in the lakes by intercepting nutrients normally transported from near shore areas. They also selectively filter out algae, which he said can lead to blooms of the types of algae they don’t like such as harmful cyanobacteria.
Why are mussels bad for lakes?
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.
Can you eat zebra mussels?
Are Zebra Mussels edible? Most clams and mussels are edible, but that does not mean they taste good! Many species of fish and ducks eat Zebra Mussels, so they are not harmful in that sense. To be safe, it is not recommended to eat Zebra Mussels.
Are zebra mussels good for anything?
Water clarity Mussels are filter feeders, which means they feed by clearing nutrients from the water passing through them. 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.
Can you see shipwrecks in Lake Michigan?
There are nearly 1,500 shipwrecks sprawled across Lake Michigan’s sandy floor, many dating back to the early 1800s! Even though we view Lake Michigan as a point or recreation for boating, swimming, and fishing (our favorite beaches too!)
Will zebra mussels ever go away?
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.
Do zebra mussels bite?
Just like many other bivalves, zebra mussels are filter feeders. They eat by sucking in water, filtering out all the particles, and spitting out what they do not want (along with the water). For us, it would be like turning a piece of cake into crumbs and “breathing” them in instead of just taking a bite.
What is the natural predator of the zebra mussels?
Zebra mussels do not have many natural predators in North America. But, it has been documented that several species of fish and diving ducks have been known to eat 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.
What are the signs and symptoms of zebra mussels?
The presence of invasive species like Zebra Mussels are warning signs that your lake is under environmental attack. Like the human body, when a lake is sick, symptoms appear.
- The lake is overloaded with nutrients.
- The bottom of the lake is a compost pile.
- There’s not enough oxygen circulating from top-to-bottom.
What are the negative effects of zebra mussels?
Zebra Mussels are especially harmful for native mussels, many of which are species at risk. They outcompete these species for food and will attach themselves to native mussels, suffocating them.
Do 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.
Can zebra mussels make you sick?
Zebra mussels have been devastating the Higgins Eyes in the Lake Pepin area. In Michigan, where zebra mussels have infested more than 200 lakes, blue-green algae blooms — the kind that can make people sick and have killed animals that drink the water — are enjoying a resurgence of sorts.
