Fish Health Events At British Columbia Marine Finfish Aquaculture Sites

This report provides a summary of fish health events reported by aquaculture companies to Fisheries and Oceans Canada (DFO). A fish health event is any suspected or active disease that occurs within an aquaculture facility that requires the involvement of a veterinarian and warrants mitigation measures (e.g., treatment, quarantine, reduction in density). As a condition of licence, company veterinarians must notify DFO within seven days of any fish health event on a farm and provide a preliminary or confirmed farm-level diagnosis as well as details on any sampling, monitoring or mitigation measures planned or performed.

Historical data are available from 2016 to the present. Prior to this time, fish health event reporting was not required by conditions of licence.

The terminology used in the report’s column headings is defined in the terminology file below.
