Why are zebra mussels so bad?

Today, scientists know that zebra mussels can cause increases in toxic blue-green algae, including Microcystis, which produces a poison that causes liver damage when ingested by humans and wildlife. Decaying algae can make waters uninhabitable by causing low levels of dissolved oxygen that result in fish kills.

Are zebra mussels harmful to humans?

– 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.

How were zebra mussels introduced in the United States?

The Zebra Mussel was first identified in the United States in the waters of Lake St. Clair in June of 1988. It is believed that Zebra Mussels were introduced into North America through the emptying of ballast water from commercial transatlantic ships into the Great Lakes.

Does anything eat zebra mussels?

In North America, diving ducks can eat mussels. Fish species commonly found in Manitoba such as freshwater drum, lake sturgeon, channel catfish or common carp may learn to eat zebra mussels, even crayfish may also feed on them. However none of these Manitoban predators have evolved with zebra mussels.

Can you get rid of zebra mussels?

Biologists who have studied zebra mussels recommend using high-pressure hot water to remove and kill zebra mussels that are attached to your boat hull (use water >104 degrees F if possible). It is okay to use high-pressure cold water if hot water is not available.

Does bleach kill zebra mussels?

A 2% chlorine bleach solution is effective at killing zebra mussels when cleaning boating equipment or other gear away from waterbodies. A bacterial formulation is currently being researched, which uses a native soil bacterium to kill zebra mussels without causing other damage to the ecosystem.

What is the natural predator of the zebra mussels?

Several organisms, such as diving ducks, crayfish, eel, common carp, pumpkinseed, European roach, and freshwater drum, have been found to consume zebra mussels. Several other fish species are listed as potential predators of zebra mussels because of their historic consumption of other native molluscs.

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.

How long can Zebra mussels live out of water?

about 7 days
