Zebra and Quagga Mussels

For the past few years, the Boundary Invasive Species Society has been taking water samples from Jewel Lake and Idabel Lake to check for the presence of invasive zebra and quagga mussels. This year we are only sampling Jewel Lake. We have installed a substrate sampler in the lake for the summer season. The Christina Lake Stewardship Society checks Christina Lake. These invasive mussels are native to the Baltic region of Europe. They first came to Eastern North America in the 1980’s in the ballast water of ships from the Baltic Sea. These mussels are found in 3 Canadian Provinces and 33 American states.

Unlike our native mussels, zebra and quagga mussels are smaller and attach to hard surfaces. They have been found at inspection stations attached to all sorts of watercraft, including kayaks. It is important that you stop at all watercraft inspection stations to ensure you watercraft is clean. You can also contact the Conservation Officers Service to request your boat be inspected. If you are importing a boat from a high-risk area you want to get it inspected before it is launched in B.C. waters. I have talked to several people from Ontario over the past few summers about the impacts of zebra and quagga mussels. One man said he had scars on his feet from the sharp shells on the beach. Another person said that everyone wears shoes to the beach and when they go swimming, so they don’t get their feet cut up on the shells. The native fish, mussels and aquatic plants have all been impacted. The costs of dealing with invasive mussels in Ontario is almost $100 million a year. These invasive mussels have massive environmental and economic impacts. Once established they are virtually impossible to get rid of. Prevention is our only option.

Thanks to the Habitat Conservation Trust Fund and the Province of British Columbia for funding and administrating the Invasive Mussel Monitoring Grants. This grant enabled us to monitor Jewel Lake for these invasive aquatic mussels. Let’s all keep working together to Protect Our Waters from invasive species!
