The Manitoba government is increasing its attempts to stop the spread of Aquatic Invasive Species(AIS) by introducing new AIS control zones and inspection stations.

Natural Resources and Northern Development Minister Greg Nesbitt made the announcement today, saying in a news release that these control zones are critical to containing the spear of AIS.

"Watercraft users will need to undertake several mitigation measures such as cleaning, draining, drying and decontaminating watercraft to effectively prevent the spread of aquatic invasive species within Manitoba."

New measures that have been imposed include:

  • Designating a new Lake Manitoba/Fairford River/Lake St. Martin control zone to control the spread of zebra mussels
  • Designating a new Shoal Lake control zone to control the spread of spiny water fleas
  • Updating the names and boundaries of existing control zones to more accurately target areas where invasions exist
  • Amending the aircraft control zone provision so that any float plane using a zebra mussel control zone must have its underwater surfaces such as floats treated with anti-fouling paint

The government is also introducing new inspection stations in Ste. Rose du Lac, Minnedosa, and Grand Rapids in the coming weeks. These stations are intended to help respond to growing zebra mussels and other AIS threats in western Manitoba.
