Emerson, Manitoba - Aquatic invasive species (AIS) can cause significant ecological and economic impacts on freshwater ecosystems in Canada. That's why, for the third year in a row, Fisheries and Oceans Canada (DFO), in collaboration with the Canada Border Services Agency (CBSA), inspected and decontaminated watercraft to ensure they were free of Zebra Mussels and other AIS, helping to protect Canada's ecosystems, biodiversity, and economy.
This spring through fall, DFO staff and fisheries officers, along with CBSA officers, conducted 804 watercraft inspections at the Emerson-Pembina international border crossing in southern Manitoba. Watercraft were inspected to ensure they were cleaned, drained and dried (CDD). These steps are critical to preventing the spread of AIS between different bodies of water.
The results of this year's inspections highlight the value of raising awareness and preventing AIS from spreading:
- 274 watercraft (34%) had not been cleaned, drained, or dried (CDD) and failed the inspection.
- 96 decontaminations (12%) were performed.
- 1 mussel-fouled watercraft (1.3%) were denied entry into Canada.
- 2 watercraft (0.2%) were denied entry due to being overly fouled by organisms other than mussels.
These findings underscore the importance of informing all watercraft users about how critical the clean, drain, dry process is to prevent the spread of AIS. Results from previous years show similar trends, emphasizing the need for continuous monitoring.
Looking ahead to 2025, DFO plans to continue the Emerson-Pembina watercraft inspections in collaboration with CBSA. This ongoing effort aims to ensure that watercraft are free of AIS, protecting Canada's waters for future generations.
