Saskatchewan’s Ministry of Environment is reporting some good news, as no invasive species of mussels were found over the course of 2024.

According to an announcement Monday, the province’s aquatic invasive species (AIS) monitoring program reported that no invasive zebra or quagga mussels or spiny water flea were found in Saskatchewan waters.

More than 450 water samples were tested from waterbodies across Saskatchewan. Additionally, more than 3,500 watercrafts were tested – which saw ministry staff intercept and decontaminate six watercraft carrying zebra or quagga mussels.

A further 250 watercrafts travelling from high-risk areas into the province were decontaminated by the ministry, after they were not properly cleaned, drained or dried.

“Our surveys confirm that Saskatchewan’s efforts to protect our lakes and rivers from AIS have been successful,” Environment Minister Travis Keisig said in the news release.

“Collaborating with our partners, the ministry will continue to implement a robust AIS prevention program that includes monitoring, roadside watercraft inspections and decontamination, and public awareness and education, to ensure that success continues.”

Invasive mussels have continued to spread across the continent, including in Manitoba, Ontario and Quebec in addition to 34 states.

The species pose a serious threat to the province, as once they are established, they are nearly impossible to eliminate.

The province reminds residents to carefully follow the clean-drain-dry protocols for watercraft and gear that comes in contact with the water before moving between waterbodies.

Residents must also stop at roadside watercraft inspection stations or risk a $500 fine, plus an $80 surcharge.

The removal of drain plugs on all watercraft during transport is required by law.

Saskatchewan’s AIS program also focused on several species of invasive fish, including goldfish, koi and Prussian carp, as well as flowering rush, an invasive aquatic plant that can quickly outcompete native plants in the province’s waterways.
