Zebra Mussels
Zebra mussels have the potential to harm aquatic ecosystems and impact municipal and agricultural water systems.
Zebra mussels are filter feeders that consume plankton and algae in the water. Each individual is capable of filtering over one liter of water per day.
Zebra mussels also become troublesome for recreational users and water users when they attach to the insides of engine cooling systems and water intake structures, restricting the movement of water. The shells are extremely sharp which could potentially limit the use of swimming beaches.
In some areas of the country, zebra mussels have been found in densities of over 700,000 individuals per square meter.
