NAFO Division 4T Atlantic Herring Landings by Year, Stock, and Gear

Fisheries and Oceans Canada provides this dataset to monitor commercial landings of Atlantic herring in NAFO Division 4T. It contains landings in metric tonnes, broken down by year, spawning stock (spring and fall spawners), fishing season, and gear type (fixed and mobile). Stock identification is determined through weekly port sampling, and daily landings data are sourced from the DFO Statistics Branch.

Use Cases

• Modeling stock biomass trends based on annual landings data.
• Analyzing seasonal fishing pressure based on spring and fall season data.
• Comparing fishing efficiency and selectivity based on fixed and mobile gear types.
• Assessing spawning stock composition based on port sampling for spring and fall spawners.

Strengths

• Data is structured by multiple key dimensions: year, spawning stock, fishing season, and gear type.
• Stock identification is supported by a concrete sampling method: two fish samples per week per area.
• Landings data are sourced from an official branch: the DFO Statistics Branch.

Limitations

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