Pacific Salmon Catch Data From Coded-Wire Tag Sampling

Yearly catch and sample data for tagged adult salmon are collected from commercial, recreational, tribal, and escapement fisheries across the Pacific coast. Fisheries and Oceans Canada maintains this centralized database, which includes information on sampling area, number caught, and percent of catch sampled. The dataset was last updated in March 2026.

Use Cases

• Analyze spatial trends in salmon catch by sampling_area across different fishery types.
• Model the relationship between the number_caught and the percent_sampled to estimate total fishery impact.
• Track annual submission patterns from specific reporting_agencies to assess data collection consistency.
• Compare catch data between commercial, recreational, tribal, and escapement_fisheries.

Strengths

• Data collection spans multiple fishery types and agencies across the Pacific Coastwide region.
• Centralized database managed by a national government agency (Fisheries and Oceans Canada).
• Data is submitted on a yearly basis, providing regular updates.

Limitations

• Specific row count, column count, and temporal coverage are unknown.
• Geographic detail is limited to 'Pacific Coastwide' without specific coordinates.
• Data completeness relies on submissions from various sampling agencies, which may vary.
