Zebra mussels filter large quantities of plankton from the water column, depriving fish and other aquatic life of a valuable food source.
How might zebra mussels be used to improve lake systems quizlet?
Zebra mussels ( can or cannot) attach themselves directly to soft, muddy surfaces on the floors of the Great Lakes. In terms of water depth, light intensity, and water temperature, the zebra mussel is a (specialist or generalist) species.
What are the benefits of zebra mussels?
Adult zebra mussels feed by filtering large amounts of plankton and detritus from the water. Each mussel can filter one liter of water per day! Zebra mussels thrive in nutrient-rich water which supports healthy populations of plankton.
How do zebra mussels affect water quality?
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.
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.
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.
How are humans trying to control zebra mussels?
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. Drain all bilge water, live wells, bait buckets, and all other water from your boat, engine and equipment.

What states have zebra mussels?

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.

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 will happen if zebra mussels are not controlled?
These tiny invaders adversely affect phytoplankton and zooplankton populations, kill native mussels, ruin fish spawning areas, damage structures and clog water supply pipes and facilities.
What happens to a lake with 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.
