What are they?

Zebra and Quagga mussels are freshwater molluscs. They first arrived in the ballast water of ships from the Baltic Sea in the 1980s, and are highly invasive.

Miniature, but mean!

The impacts of these tiny mussels are devastating to ecosystems, infrastructure, economies, culture, and recreation.

ecosystems

  • alter food webs

  • concentrate pollutants in their waste

  • displace native bird, fish and plant populations

infrastructure

  • clog pipes, water intake systems, and municipal water supply

  • damage pumps and hydroelectric power generating facilities

culture

destroy culturally significant areas for indigenous nations from traditional fishing areas to the water itself

economy

  • injure tourism and literally injure tourists (and locals alike) by fouling beaches with razor sharp shells and decay odour

  • reduce real estate values

recreation

  • hurt marine industry by impairing the structural integrity of steel

  • cause damage to external and hard-to-reach internal watercraft equipment

Both zebra and quagga mussels can be found

in densities of 10,000 individuals

per square metre at the bottom of the lake!

They can survive for several weeks without being immersed in water, if they’re left in a cool and moist environment (for example, on an undried boat).
