What is the economic impact of zebra mussels?
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.
Why are zebra mussels important?
Zebra mussels are an invasive, fingernail-sized mollusk that is native to fresh waters in Eurasia. They filter out algae that native species need for food and they attach to–and incapacitate–native mussels. Power plants must also spend millions of dollars removing zebra mussels from clogged water intakes.
Why are zebra mussels so successful?
Zebra mussels are very successful invaders because they live and feed in many different aquatic habitats, breed prolifically (each female produces 1 million eggs per year), and have both a planktonic larval stage and an attached adult stage.
What is the government doing about zebra mussels?
The Government of Canada is committed to taking action on aquatic invasive species, including Zebra and Quagga mussels, by investing in the necessary research to understand the threat, and to educate the public on how they can help to prevent the spread.
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.
How do zebra mussels affect humans?
The toxin is also believed to be responsible for liver damage in humans. Surprisingly, zebra mussels seem to have no effect on the amount of blue-green algae in lakes with high levels of phosphorus, a nutrient that builds up in lakes and other bodies of water as a result of erosion, farm run-off and human waste.
What are the negative effects of zebra mussels?
Zebra Mussels are especially harmful for native mussels, many of which are species at risk. They outcompete these species for food and will attach themselves to native mussels, suffocating them.
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.
How do zebra mussels harm the environment?
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.
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.
How do you get rid of zebra mussels?
Help stop the spread of zebra mussels
- 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 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.
What are the signs and symptoms of zebra mussels?
The presence of invasive species like Zebra Mussels are warning signs that your lake is under environmental attack. Like the human body, when a lake is sick, symptoms appear.
- The lake is overloaded with nutrients.
- The bottom of the lake is a compost pile.
- There’s not enough oxygen circulating from top-to-bottom.
How were zebra mussels introduced to Ontario?
Zebra and Quagga Mussels Both Zebra and quagga mussels are native to the Black Sea in Eurasia and were introduced to Ontario in the late 1980s via ship ballast. They both have the capability to densely colonize hard and soft surfaces of lake bottoms.
How fast do Zebra mussels reproduce?
Lifecycle. The lifespan of a zebra mussel is four to five years. A female zebra mussel begins to reproduce within 6–7 weeks of settling. An adult female zebra mussel can produce 30,000 to 40,000 eggs in each reproductive cycle, and over 1 million each year.
