South Coast BC Chinook Salmon Biological Catch Data with Genetic Stock IDs

Biological data for Chinook Salmon sampled from South Coast British Columbia mark-selective fisheries, initiated in 2023. Each record includes catch date, location, fork length, adipose fin clip status, and detailed genetic stock identification with probability scores. The dataset supports the Pacific Salmon Strategy Initiative's multi-year monitoring program.

Use Cases

• Estimate the proportion of hatchery-marked Chinook using the adipose fin clipped field across different creel sub-areas.
• Analyze stock composition by aggregating the resolved stock region and resolved stock region probability for fisheries management.
• Model fish length (cm) distributions segmented by DNA Stock Region 1 assignments to assess size-class variations.
• Validate fishery-dependent estimates by comparing catch date and location data with recreational catch monitoring programs.

Strengths

• Data includes detailed genetic stock identification with up to five ranked probability assignments per fish.
• Records are part of a multi-year monitoring program funded by the Pacific Salmon Strategy Initiative, initiated in 2023.
• Stock assignments integrate both fine-scale (DNA Stock X) and broad-scale (resolved stock region) classifications aligned with management units.

Limitations

• Sample size and total row count are unknown, limiting assessment of statistical power.
• Genetic assignments for some records may be deterministic via parentage-based tagging, lacking probabilistic uncertainty measures.
• Geographic coverage is limited to South Coast BC mark-selective fisheries, not representing all Chinook populations.
