Zebra mussel facts
- Species name: Dreissena polymorpha
- Native to Eastern Europe/Western Asia.
- They can be found in freshwater lakes, ponds, and rivers, as well as all kinds of hard surfaces.
- Zebra mussels typically live 2-5 years in temperate climates, with water temperatures ranging from 32 - 90 °F.

The zebra mussel is native to Eastern Europe and Western Russia. The species was unintentionally introduced into the United States’ Great Lakes through the discharge of contaminated cargo ship ballast water. They were first discovered in the Great Lakes in 1988 and were first confirmed in the Duluth/Superior Harbor in 1989.
Where are zebra mussels native to?

June, 1988The first North American zebra mussel discovery was in Lake St. Clair, Michigan, in June, 1988. The mussel has expanded to infest many lake and river systems of North America since then. During the summer of 1993, the zebra mussel was discovered in Lake Champlain, Vermont.

Most clams and mussels are edible, but that does not mean they taste good! Many species and fish and ducks eat zebra mussels, so they are not harmful in that sense. Zebra mussels are so small and do not have much in the way of "meat" inside them, you would have to be pretty hungry to want to eat them.
How long can zebra mussels survive out of water?
Zebra mussels are thought to have arrived in the great lakes within water discharged from ships that came from Europe. From then on, they have become famously resilient hitchhikers that attach themselves to boats, swim rafts, boat lifts, and docks. Zebra mussels can only survive outside of water for about five days.

It is illegal to own, sell or distribute live zebra mussels in the U.S. The USGS received the first reports during the last week of February and raised the alarm to other federal and state agencies, which have since sprung into action.
What water temperature kills zebra mussels?
about 98°FIn cold weather, mussels may survive in anoxic water for up to two weeks. A faster method of killing zebra mussels without damaging the environment would be to heat the water to a temperature high enough to kill zebra mussels (about 98°F, 37°C).

Why do zebra mussels outcompete natives?
The zebra mussels also outcompete the natives for food and space, and because of their fast reproduction can quickly overwhelm a water system. The feeding habits of zebra mussels can also have a drastic impact on an infested lake. Zebra mussels are filter feeders that siphon particles of plankton from the water.
What is the National Park Service doing to stop zebra mussels?

How long does it take for a zebra mussel to dry?
To prevent this, boaters must take care to drain their boats, motors and livewells before leaving a lake or river, wash their boat and trailer thoroughly, and allow it to dry for at least five days (the amount of time a zebra mussel can survive out of water) before taking the boat out again.
Do zebra mussels have to be removed?
Once a population of zebra mussels has become established in a water body, there is very little to be done to remove them.

So whatever is in the ballast can travel thousands of miles before being released into new waters. Zebra mussels were first discovered in Detroit's Lake St. Clair in 1988. They would have been brought there in ballast water, survived, and reproduced to a number where they were noticed.
Where do zebra mussels come from?
Zebra Mussels are originally from the Caspian Sea region of Northern Iran, Azerbaijan, southern Russia, Kazakhstan, and Turkmenistan. Due to extensive trade between this region and Europe during the 17th and 18th centuries they were able to spread. Zebra mussels were carried with the trade vessels to Europe and spread throughout the continent, ...
Why do zebra mussels attach to native mussels?
In addition, zebra mussels attach themselves to native mussel so the natives can't eat, breathe or reproduce.
How long do zebra mussels stay in the water?
When zebra mussels are larvae, less than 3 weeks old, they float in the water and move with the current. After three weeks, they settle down in the river or lake to find a good hard surface upon which to attach.

Why are zebra mussels banned in Manitoba?
In May, 2014, the government of Manitoba temporarily closed four harbours where zebra mussels had been found in order to treat them with liquid potash, a substance harmless to humans but lethal to mussels. The experimental action was an attempt to eradicate the unwanted mollusks before they could further establish themselves in the lake.
Why are mussels not evenly distributed around the lake?
Because the mussels primarily inhabit rocky areas and infrastructure around the lake edges, impacts will not be evenly distributed around the lake. Some coastal areas may see improvements in water clarity, particularly between wind storms.

What is a zebra mussel?
Zebra mussels are small animals with a striped, D-shaped shell composed of two hinged valves joined by a ligament. The shells are typically one-quarter inch to one and one-half inches long, depending on age, with alternating yellow and brownish colored stripes. Adults are typically fingernail-sized. Zebra mussels attach to hard surfaces underwater.
How do zebra mussels spread?
People spread zebra mussels primarily through the movement of water-related equipment. Mussels attach to boats, docks, swim rafts and boat lifts. They can also attach to aquatic plants. Adult mussels can survive out of water – less than five days in dry conditions, but up to 21 days in very wet conditions (such as inside dock/lift pipes). Microscopic larvae (veligers) can survive in water contained in bait buckets, live wells, bilge areas, ballast tanks, motors and other water-containing devices.
How much water does a zebra mussel filter?
A single zebra mussel can filter one quart of water per day while feeding primarily on algae. They live underwater, attached to natural and manmade substrates such as rocks, wood, plants, native mussels, pipes, docks, boat lifts, swim rafts, moored watercraft, and other debris.
Can zebra mussels be killed in open water?
Many pesticides used in closed systems are not allowed for use in open water. In natural waters, such as lakes or rivers, attempts to control zebra mussels are uncommon and considered experimental.
