Average monthly mortality of cultured salmon at BC aquaculture sites Determining the average mortality rate and analyzing the cause of mortalities in salmon cultured at British Columbian. aquaculture facilities provides insight into effectiveness of the fish health management practices of the industry. It can also help to identify seasonal trends in disease prevalence, which assists resource managers of both wild and cultured stocks in predicting and developing strategies to deal with potential outbreaks. This report provides a quarterly snapshot of the average monthly mortality rate of cultured salmon in British Columbia. The number of fish that died in the month is expressed as a fraction of mid-month inventory for the farm. This is for all causes of death combined.

This report groups data by species and zone; an average of the monthly mortality rates from the contributing farms is used to generate a quarterly number. Weighting is used to adjust for fallow farms, and to determine the extent to which the mortality of each facility contributes to the average mortality rate of the zone, based on the number of months that the site was active. This approach reflects the dynamic nature of fish populations and inventories (i.e. changing from 1st-year fish to 2nd-year fish; from active to fallow facilities) at salmon aquaculture facilities. Certain zones have been combined, where few sites exist, in order to maintain consistency with historic reporting of fish health data.
