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.
alter food webs
concentrate pollutants in their waste
displace native bird, fish and plant populations
clog pipes, water intake systems, and municipal water supply
damage pumps and hydroelectric power generating facilities
destroy culturally significant areas for indigenous nations from traditional fishing areas to the water itself
injure tourism and literally injure tourists (and locals alike) by fouling beaches with razor sharp shells and decay odour
reduce real estate values
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).
