Atlantic Salmon Smolt Abundance Data from Kedgwick River, New Brunswick

Atlantic salmon smolt abundance data collected via a Rotary Screw Trap on the Kedgwick River each spring (May-June). Fisheries and Oceans Canada records species counts and measures length and weight for a portion of captured smolts, using a capture-mark-recapture method to estimate trap efficiency and population size. The data was last updated on 2026-03 24.

Use Cases

• Estimate Atlantic salmon smolt population abundance based on the capture-mark-recapture experiment described.
• Analyze seasonal migration patterns based on spring (May-June) collection data.
• Model fish growth and size distributions based on recorded length and weight measurements.
• Assess trap efficiency and recapture rates for salmon smolts from the tagging data.

Strengths

• Data benefits from referential integrity and defined data types due to storage in a relational database.
• An additional layer of quality control is provided by entry into a web application from field data sheets.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
