Aquatic Invasive Species (AIS)

Posted on: January 19, 2016  |   , ,

An aquatic invasive species (AIS) can either live in freshwater or marine environments. The majority of the species of concern to Manitoba, such as Zebra and Quagga mussels, Spiny Waterflea, Rusty Crayfish and Asian Carp are freshwater species. Manitoba currently has 15 aquatic invasive species.

Zebra Mussels in Manitoba

Zebra Mussels were confirmed in Lake Winnipeg in the fall of 2013 and the Red River and Cedar Lake 2015.

Zebra Mussels are small (1 – 3 cm), clam-like aquatic animals that are a significant environmental and economic concern to Manitoba.   Adult Zebra Mussels have a shell and can strongly attach to water-based conveyances such as watercraft, trailers, water-based aircraft, ORVs and other water-related equipment. They can survive out of water for 7 to 30 days depending on temperature and humidity.

Once Zebra Mussels become established they cannot be eradicated, so it is extremely important to stop their spread.

Whiteshell Cottagers should ensure that they are taking  measures to protect the lakes in provincial parks.

To Stop the Spread of Zebra Mussels

CLEAN + DRAIN + DRY your watercraft, trailer and all water-related equipment and DISPOSE of any unwanted bait in the trash.

    I do not see much effort to stop the spread of Zebra mussels? Given the amount of trailered boat traffic I think parks should seriously look at suspending or supervising entry into the lakes. The cost may be fairly large but it sounds like a lake invested with zebra mussels would really hurt the local economy and property values?
