Invasive Asian clam shells found on Shuswap Lake beach may indicate a new infestation, highlights importance of Clean-Drain-Dry.

Clam shells found on a beach in the Shuswap last fall have been identified as invasive Asian clam.  At this time only dead shells have been found.

“The Provincial staff have told us they have not confirmed any live individuals, and indicated that monitoring will continue for the coming season” says Sue Davies, Aquatic Coordinator for the Columbia Shuswap Invasive Species Society.

However, populations of the invasive clam aren’t far off: they do exist in several lakes in the lower mainland and are widely distributed in Washington State. This is the first indication that they may have spread to Shuswap Lake. Members of the public are asked to please report any suspected invasive species via the Provincial “Report Invasives BC” smartphone application (available for download from www.gov.bc.ca/invasive-species) and any suspected invasive zebra or quagga mussels to the Report All Poachers and Polluters hotline 1-877-952-7277.

Asian clams are small bivalve shellfish, originating in Asia. They are considered invasive due to their negative impacts on many North American waterways.

Columbia Shuswap Invasive Species Society (CSISS) provides education and information to the public regarding invasive species such as Asian clam. CSISS has been monitoring lakes in the region for invasive species as part of the Ministry of Environment and Climate Change Strategy’s provincial lake monitoring program.  To date, none of the samples from Shuswap Lake have come back positive for Asian clam larvae.

The larvae of Asian clam are microscopic and could potentially be transported in standing water in boats.  Adult Asian clams are also small – the size of a fingernail – and could be embedded in mud on a boat or boat trailer.

“It’s possible that Asian clams came to the Shuswap as fishing bait, as live food, or accidentally inside a watercraft,” says Davies. “It is super important not to transport invasive species.  Never release live animals or plants into waterways, and remember to Clean Drain and Dry your watercraft when moving it between waterbodies,” she adds. “We encourage all boaters, anglers, and paddlers to Clean Drain Dry their watercraft and gear every time they move from one lake to another because it is the most effective way to prevent the spread of invasive species.”

“Just walk around your boat, remove any mud or plants, drain compartments, mop up standing water with a chamois cloth, and make sure everything, including your fishing gear, is properly clean and dry before relaunching into a new lake or river.  It’s pretty simple and can prevent a world of problems,” explains Davies.

Asian clams are self-fertile, so a single clam can start a new population. They can produce up to 70,000 eggs per year and can reach densities of up to 20,000 individuals per square meter of lake bed.  They are filter feeders and can reduce biodiversity and food available for fish.  Dense populations may have the potential to clog filters on hydro systems and water pipes, imposing costly maintenance.  They are also known to harbour parasites that are harmful to humans if the clams are consumed raw.

You’re Invited: CSISS Annual Land Manager Meeting March 4, 2020

Event Details:

Date: Wednesday March 4, 2020
Time: 1:00 pm – 4:00 pm
Location: Revelstoke Community Centre, MacPherson Room, 600 Campbell Ave. Revelstoke, BC.

Please register for the Annual Land Manager meeting HERE !

Written feedback (e.g. on Priority Invasive Plant Lists) is also welcomed before February 18, 2020 to info@columbiashuswapinvasives.org

Annual Land Manager Meeting: The CSISS is completing its annual review of the priority invasive species list and watchlists from the 2020-2025 Columbia Shuswap Operational Plan for Invasive Species. In particular, the priority invasive plant lists help guide inventory, treatment, monitoring and data management of invasive plants within the Columbia Shuswap Regional District.

The goal of this meeting is to enable land managers to provide guidance and input on the priority invasive plant lists, watchlists and best practices within the region. The meeting objectives are to: 1) Share updates on invasive species management activities of each organization; and 2) Revisit prioritization of invasive plant species and activities for treatments, inventories, monitoring and data management and 3) any other invasive species updates and presence/absence updates to the regional watchlists.

Here is a link to the 2020- 2025 Columbia Shuswap Operational Plan for Invasive Species including the priority plant list and regional watchlisthttps://columbiashuswapinvasives.org/wp-content/uploads/2019/09/Columbia-Shuswap-Operational-Plan-2019_v6_Aug23.pdf

Your input is critical in ensuring the delivery of an effective, efficient, and coordinated invasive species program in the Columbia Shuswap. We appreciate your feedback as key partners and Board members in helping with this process.

Another year has passed with no invasive mussels detected in the Columbia Shuswap! 2019 was a successful year for CSISS- Take a look at our newsletter below to see what we accomplished this past year.

Happy New Year!

2019 was a fantastic year for CSISS thanks to our dedicated board of directors, staff and volunteers. We extend out gratitude to our funders and supporters this past year!

Highlights from the past year

Great News for Columbia Shuswap Watersheds: No invasive mussels detected in 2019!

Another year with no invasive mussels detected in any of the 12 water bodies tested!
Freshwater lakes and rivers are not only vital for recreation and tourism, but are also an integral part of the economy in our region.  Invasive mussels could cost millions every year in infrastructure maintenance if they were to enter BC waterways.
Protecting infrastructure and native ecosystems from the negative impacts of aquatic invasive species is a priority.  Please ensure that all watercraft entering BC are inspected for invasive species, and that you Clean Drain and Dry your watercraft when moving from one water body to another within BC.
Upcoming Events:

Jan 31st- Shuswap Trails Working Group Meeting
Feb 11th-13th- INVASIVES 2020- Invasive Species Council of BC Annual Forum
