Where are quagga mussels found?
Quagga mussels are native to the Dneiper River drainage of Ukraine. They most likely arrived in the ballast water of ocean going ships. The quagga mussel was first sighted in the Great Lakes in September 1989.
Where were invasive mussels first discovered?
Quagga mussels were first found in the USA in the Great Lakes in 1989, Nevada in 2007, and California in 2008. Ballast water discharge from transoceanic ships is thought to be responsible for the long distance spread of zebra and quagga mussels from their original home ranges in eastern Europe.
How did the quagga mussel get to Michigan?
Quagga mussels, which arrived in Lake Michigan in the 1990s via ballast water discharged from ships, have colonized vast expanses of the Lake Michigan bottom, reaching densities as high as roughly 35,000 quagga mussels per square meter.
Where were quagga mussels first found in the US?
The quagga mussel was first observed in North America in September 1989, when it was discovered in Lake Erie near Port Colborne, Ontario. It was not identified as a distinct species until 1991.
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.
Does anything eat quagga mussels?
Results showed that some fish will consume significant amounts of quagga mussels and some will not. Thus, redear sunfish and other predators may contribute to controlling mussels, but probably will not eradicate them in areas where the species co-occur.
Where are 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.
Do quagga mussels eat zebra mussels?
In areas where both mussel species coexist, Quagga mussels often outcompete zebra mussels. Quagga mussels are extremely effective filter feeders, removing large amounts of phytoplankton and suspended particulates from the water.
Are zebra mussels harmful to 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.
Are zebra mussels bad for a lake?
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.
Why are quagga mussels a major issue in Lake Michigan?
That’s because the quagga mussels filter and feed on so much of the lake’s phytoplankton — a wide variety of microscopic plants — which leaves the invertebrate animals with nothing to eat.
Are quagga mussels the same as zebra mussels?
But the cousin species are different in many ways, too. Zebra mussels prefer to attach to a hard surface, while quagga mussels can live on soft bottoms, such as sand or silt. Zebra mussels also prefer warmer water temperatures and do not grow as big as quagga mussels.
What damage is the quagga causing?
Damaging Ecosystems Quagga and zebra mussels damage the ecosystems they invade. They feed by filtering water and removing large amounts of food, effectively starving native species in infested rivers and lakes.
How much does it cost to try to control the zebra mussels each year?
Maintenance of pipes clogged with zebra mussels costs the power industry up to $60 million per year and temporary shutdowns due to insufficient water flow can cost over $5,000 per hour. The total cost to the United States of the zebra mussel invasion is estimated at $3.1 billion over the next ten years.
