Invasive Mussel Defence Program
The B.C. Invasive Mussel Defence Program’s goal is to prevent the introduction of zebra and quagga mussels (ZQM) into B.C. The program’s prevention efforts are focused on inspecting boats, monitoring lakes, educating the public and coordinating actions with neighbouring jurisdictions.
The Invasive Mussel Defence Program (IMDP) was created in 2015 and has three main components:
- A watercraft inspection program to detect and respond to high-risk watercraft potentially transporting invasive mussels into B.C. from infested lakes or rivers
- Lake monitoring to confirm the continued absence of invasive mussels in B.C. waters
- Outreach and education to educate people and change behaviour by promoting the message of "clean, drain, dry" to the boating community, in collaboration with partners
Provincial legislation gives the Province authority to take action on ZQM. The Controlled Alien Species (CAS) Regulation under the Wildlife Act is the principle legislation that defines, lists, and affords provisions to regulate invasive mussels in B.C.
Under the CAS Regulation, prohibitions apply to any mussel listed in Schedule 4 (Zebra, Quagga, and Conrad’s False Mussel). Specifically, it is illegal for a person to:
- possess, breed, ship, or transport prohibited mussels
- release prohibited mussels into B.C. waters
- allow a prohibited mussel to be released or escape into B.C. waters
Inspectors are trained in the watercraft inspection program and have been designated as auxiliary conservation officers under the Environmental Management Act. This designation provides powers to stop, inspect, search, question, and give decontamination orders. See the Zebra and Quagga Mussel Early Detection and Rapid Response (ZQM EDRR) Plan (PDF) for more information on the CAS Regulation and ZQM.
2015-2022 Watercraft Inspection Seasons
The provincial Invasive Mussel Defence Program began in 2015 and has adapted and expanded each year through additional funding through partnerships with BC Hydro, Columbia Power Corporation, Fortis BC, Columbia Basin Trust, and the BC Government. The tables below show a summary of the 2015-2022 watercraft inspection seasons and what they found.

Program Funders
Aquatic Invasive Species K9 Unit
In 2017, the program started the Aquatic Invasive Species K9 unit. The first of B.C.’s multipurpose detection dogs was Kilo. The primary handler of Kilo is Sergeant Josh Lockwood within the Conservation Officer Service (COS). Kilo is trained to detect invasive mussels, firearms and bear parts, and helps in evidence recovery cases within the Conservation Officer Service. In his first year, Kilo conducted more than 900 inspections and found invasive mussels on two watercraft.
In the fall of 2018, a second multipurpose detection dog, called Major, joined the K9 unit. Major is a German shepherd whose primary handler is Sergeant Cynthia Mann. These dogs are valuable tools for detecting invasive mussels on watercraft travelling through and into B.C.
