Why is it a problem?
- Quagga are prodigious water filterers, thus removing substantial amounts of phytoplankton from the water and altering the food web.
- Quagga mussels clog water intake pipes and underwater screens much like zebra mussels.
- Quagga mussels damage boats, power plants, and harbors.
- They also destroy the native mussel population.
How do quagga mussels spread?
- Quagga mussels have spread through ballast waters from transalantic ships.
- Quagga mussels attach themselves to boat hulls and trailers and can be transported this way.
How do we control quagga mussels?
