Zebra Mussel
Dreissena polymorpha
What are aquatic invasive species? 3
Introduced aquatic organisms that can harm native species by bringing disease and altering ecosystems. This impacts fisheries, tourism, health, and recreation.
How to identify zebra mussels 3
- Usually fingernail-sized (less than 5 cm)
- Look like D-shaped clams with yellow or brownish shells and light-coloured stripes
- Only freshwater mussels that attach themselves firmly to solid objects
How are aquatic invasive species spread? 3
Mostly by people and their equipment when they move from place to place. For example:
During water-based activities like fishing, aquatic organisms can cling to boats, fishing gear, and footwear;
Illegal dumping of aquariums.
Are there aquatic invasive species in Yukon? 3
We don’t know, which is why we need your help. Most Yukon lakes and waterways appear to be free of invasive species, but if you think you see a zebra mussel or quagga mussel please:
- Report the incident to the Fisheries Program at Environment Yukon by calling 1-800-661-0408, ext. 5721 or emailing fisheries@gov.yk.ca.
- If possible, take a photograph, a small sample for identification in a small, secure baggie and note the exact location.
- Prevent their spread with CHECK, DRAIN, CLEAN.
- If you find a potential invasive species on equipment after leaving a site, throw it in the garbage and not down the drain.
