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
Atlantic Salmon Farms
For each zone there is a graph for salmon one year or less in
seawater (year class 1) and another for salmon two years or more in
seawater (year class 2). The graphs and the tables are in format.
Pacific Salmon Farms
Sea lice on Pacific salmon are reported quarterly. The graphs and
the tables are in format.
