BCSFA Sea Lice Monitoring Results

Salmon farms report lice levels on all farms within specific fish health zones/areas as part of the Sea Lice Management Strategy. Monitoring began in October 2003.

In British Columbia, lice from wild salmon returning from the ocean to spawn can result in an increase in the levels of lice on fish farms in the fall and early winter.  Veterinarians treat these fish to reduce lice levels.

The program uses internationally accepted standards for sea lice monitoring.
