The zebra mussel had already colonized rivers and lakes across Western Europe thanks to an extensive network of canals. Scientists knew the most plausible way Santavy’s mussel could have made the trip across the Atlantic and into the Great Lakes was in the friendly confines of a freighter ballast tank.
How did zebra mussels enter the Great Lakes?
Zebra mussels probably arrived in the Great Lakes in the 1980s via ballast water that was discharged by large ships from Europe. They have spread rapidly throughout the Great Lakes region and into the large rivers of the eastern Mississippi drainage.
How was the zebra mussel introduced in North America?
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. Lawrence Seaway; three of the Finger Lakes; Saginaw Bay; and, Lake Champlain.
Are zebra mussels invasive to Lake Erie?
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. The problem is that’s about where the similarities between the invasive and native species end.
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.
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.
Do 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.
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.
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.
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.
How do you kill zebra mussels?
No chemical control agent is known to kill zebra mussels without seriously harming other aquatic life or water quality. A 2% chlorine bleach solution is effective at killing zebra mussels when cleaning boating equipment or other gear away from waterbodies.
What happens when a lake gets zebra mussels?
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 clear?
Zebra mussels are a problem because they filter water, up to a liter a day, to eat plankton. Although this filtering action may clear up the water, clear water does NOT mean clean water and the clear water zebra mussels leave behind will often lead to algal blooms that are harmful to people.
Which Great Lake has the most zebra mussels?
From their first appearance in American waters in 1988, zebra mussels have spread to a large number of waterways, including Lake Simcoe in the Great Lakes region, the Mississippi, Hudson, St.
