NAFO Division 4T Atlantic Herring Biomass Estimates with Confidence Intervals

Atlantic herring biomass estimates for the NAFO Division 4T region, covering both spring and fall stock components. Values are provided in kilotons (kt) alongside 50% and 95% confidence intervals. Fisheries and Oceans Canada updated this data following a Canadian Science Advice Secretariat (CSAS) advisory process, with the last update recorded on 2026-04 21.

Use Cases

• Modeling stock population trends based on seasonal biomass estimates.
• Assessing uncertainty in fisheries data based on the provided confidence intervals.
• Informing sustainable catch limits and management strategies based on stock biomass.
• Comparing spring and fall stock component dynamics within the NAFO 4T division.

Strengths

• Data includes both 50% and 95% confidence intervals for spring estimates and 95% intervals for fall, providing measures of uncertainty.
• Estimates are provided for distinct seasonal stock components (spring and fall).
• Data is updated through a formal science advisory process (CSAS) by Fisheries and Oceans Canada.
• Last update was on 2026-04-21, indicating recent maintenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Description metadata is limited; actual data quality requires manual inspection after download.
