Province Activates Aquatic Invasive Species Early Detection Rapid Response Plan for Assiniboine River



Manitoba Environment and Climate Change is activating its Aquatic Invasive Species (AIS) Early Detection Rapid Response Plan after positive zebra mussel veliger (larvae) samples were found in the Assiniboine River at the Brandon Generating Station. 

Dead zebra mussel veligers were detected at this location as part of Manitoba Hydro’s routine zebra mussel monitoring program and confirmed in followup sampling. 

The Early Detection Rapid Response Plan includes developing a specific monitoring plan to better understand these detections and inform the establishment of a containment plan. 

The positive samples remind the public of the importance of remaining vigilant against the spread of AIS. All water users play a critical role throughout the year in protecting Manitoba's waterbodies from the introduction and spread of AIS. 

Manitobans are reminded AIS regulations and associated set fines are in effect year-round. Continued diligence is required including during the winter season. Requirements to stop the spread of AIS before and after accessing a water body during the closed-water season are available at: www.manitoba.ca/stopais/checklist/winter.html

The Early Detection Rapid Response Plan is part of the Manitoba government’s commitment to ensure the protection of waterways by addressing the issue of aquatic invasive species. Budget 2024 includes a $500,000 investment in AIS program funding.
