Accountability and transparency

Sea lice reporting

We publicly report sea lice levels throughout the year for all of our active farm sites.

Why are sea lice counts important?

Cermaq counts lice on a weekly basis in order to meet and exceed Aquaculture license requirements and ensure the health and welfare of the fish in our care and of surrounding wild salmon.

Timely and accurate identification and enumeration is important for a few reasons:
- Provides a clear picture of the sea lice status on our fish;
- Show sea lice trends to help determine best approach to management of levels; and,
- Helps determine if a treatment is necessary and how soon it should be done.

How does Cermaq publicly report their Sea Lice counts?


- Weekly figure reported every Monday is the average sea lice abundance for the farm during the previous Saturday-Friday period;

- Where there are two sample events within one week, (pre and post-treatment), post-treatment counts will be posted on the Cermaq website; and,

- All sea lice sampling counts are reported to DFO, who then publicly report these counts on its website.

Sea lice counts updated as of June 14th, 2021
