Where were zebra mussels originally from?
Zebra mussels are an invasive, fingernail-sized mollusk that is native to fresh waters in Eurasia. Their name comes from the dark, zig-zagged stripes on each shell. Zebra mussels probably arrived in the Great Lakes in the 1980s via ballast water that was discharged by large ships from Europe.
How did zebra mussels get into Lake Michigan?
Known in Latin as Dreissena polymorpha, meaning “many forms,” the mussel is remarkably adaptable. The Dreissana was accidentally introduced into this country in 1986, arriving in the hold of a ship from the Caspian Sea. The freighter, probably a grain carrier, jettisoned its ballast water into Lake St.
How many zebra mussels are in Lake Michigan?
Declining Density in Lake Michigan Over a period of 15 years, zebra mussel densities in Lake Michigan declined from 5,200 per square meter on average to 82 animals per square meter. This decline coincides with the dramatic expansion of quagga mussel populations in the lake.
Are zebra mussels native to the Great Lakes?
Zebra mussels are not native to the Great Lakes. They were first discovered in the area in the late 1980s, and it has been an ongoing battle to get rid of and control them ever since.
Can you swim in a lake with zebra mussels?
Yes,” she said. Montz recommends checking the DNR’s map of lakes with zebra mussels before you jump in the water. The mussels don’t like sand, because there’s nothing they can attach to, so he said that you should be fine swimming on a sandy shoreline.
Do zebra mussels die in the winter?
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. Rumor: Zebra mussels will clean the water allowing weeds to take over the lake.
Can you eat zebra mussels?

Why is Lake Michigan water so clear?
They say there are so many mussels they can filter the entire volume of Lake Michigan in four to six days, and they’ve reduced the amount of light-absorbing algae by over 50 percent. Since there’s less algae, the water is less green. And according to their research, the lake’s water is also 20 percent clearer.
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!)
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.
Why are zebra mussels so bad?
Because of their ability to filter water and their high body-fat content, zebra mussels build up more than ten times the amount of PCBs and other toxic contaminants from the water than the native mussels. Some birds and fish absorb these contaminants when they feed on the zebra mussels.
Why is Lake Michigan water so blue?
Light that hits the surface of the lake from straight above penetrates more deeply, reflecting less. When the lake is deep, and the angle of incoming light is smaller, Lake Michigan’s color appears deep blue. This is because the light travels down with little obstructions and dissipates far below the surface.
Will zebra mussels kill a lake?
The problem with zebra mussels Zebra mussels also can kill native U.S. mussels by attaching to their shells. Because the mussels are so populous, they often coat the bottom of lakes and rivers where aquatic insects normally burrow and forage.
Do zebra mussels die out of water?
Zebra mussels may survive up to two weeks out of water.
Can zebra mussels be stopped?
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.
