Invasive Species Awareness Week Day 3: Mussels

We can't go through Invasive Species week without talking about one of the biggest threats in terms of invasives, Zebra, Quagga and other invasive mussels. These mussels are know for attaching themselves to every hard surface they can. Because of this they can damage infrastructure like irrigation pipes and municipal water systems which could cost millions to fix. These mussels also alter the food web, by outcompeting native species like salmon and Rocky Mountain Ridged mussels, for food and resources which would cause severe ecological damage.

They are prolific spreaders since they are so small and can live weeks out of water. Because of this, it is extremely important to follow the Clean, Drain, Dry, and Decontaminate procedures while moving watercrafts between lakes and other water bodies. This includes smaller crafts like kayaks, canoes, and paddleboards. If possible, limit the movement of watercrafts, especially between provinces.

In BC, we have not been affected by these mussels and we want to keep it that way. If you suspect you have invasive mussels, report the sighting immediately to the Conservation Officer Services: Report All Poachers and Polluters (RAPP) line: 1-877-952-7277.
