Mortality Events at British Columbia Marine Finfish Aquaculture Sites

Aggregating reported mortality events at salmon aquaculture facilities in British Columbia, where farm operators must notify authorities if dead fish exceed license thresholds. It includes mandatory reports on daily mortality counts, probable causes, and mitigation plans submitted to Fisheries and Oceans Canada. Historical data is available from 2011 onward.

Use Cases

• Analyze trends in mortality event frequency and scale using reported daily mortality counts over time.
• Identify common probable causes of mortality events to assess risk factors for farmed and wild fish populations.
• Evaluate the effectiveness of different mitigation plans applied during mortality events by correlating actions with event duration or outcome.

Strengths

• Data collection is mandated by regulation, ensuring consistent reporting from licensed facilities.
• Provides a longitudinal record with data available from 2011 to the present.
• Includes detailed event information such as cause determination and mitigation plans, as described in the source documentation.

Limitations

• The specific column structure, row count, and sample data are unavailable, limiting preliminary assessment of data granularity and completeness.
• Relies on self-reporting by aquaculture companies, which may introduce reporting biases or inconsistencies.
