Roadside inspection blitz at Manitoba-Ontario border targets spread of zebra mussels

Federal fisheries and provincial conservation officers stopped 451 vehicles at the Manitoba-Ontario border last weekend in a continued effort to battle the spread of zebra mussels.

Between Aug. 23 and 25, roadside inspectors stopped vehicles with attached boats and other watercraft driving into and out of the province, looking for signs of aquatic invasive species.

Of the watercraft examined, 153 were not cleaned, drained or dry and failed inspection. None had visible zebra mussels attached to them.

Conservation officers stopped 451 vehicles at the Manitoba-Ontario border last weekend to help curb the spread of zebra mussels.

Those drivers had their watercraft and equipment decontaminated and were given instructions for how to comply with the clean, drain and dry requirements, a news release from Fisheries and Oceans Canada said.

Jamie Moses, Manitoba’s minister of economic development, investment, trade and natural resources, said the province “remains committed to battling AIS and taking action through education and enforcement.”

“The inspections that took place… are an excellent opportunity to educate the public and stop zebra mussels from being transported,” Moses said in the release.

Clear Lake, near Riding Mountain National Park, continues to battle a zebra mussel infestation discovered late last year, forcing Parks Canada to close its waterways to boats and motorized watercraft this summer.

Parks Canada has since installed a containment curtain in parts of Clear Lake after it found an adult zebra mussel near Boat Cove in July and water samples collected from the lake in June tested positive for environmental DNA from zebra mussels.

The containment curtain is designed to isolate the location where the zebra mussels and DNA was detected.
