37 Fishing Métiers Characterization by Haul Count, Season, and Depth

Pedro Leitão's dataset characterizes 37 potential fishing métiers, sorted by the number of hauls. The data includes seasonal, geographic, depth, and sediment classifications for each métier. The summary table is based on appendix S2 and was last updated on June 2, 2026.

Use Cases

• Classifying fishing activities (métiers) based on seasonal patterns mentioned in the description.
• Analyzing the relationship between fishing depth categories and sediment types.
• Comparing validated and unvalidated métiers based on their operational characteristics.
• Mapping fishing effort across defined geographic areas (CW, NW, S, SW).

Strengths

• Provides a structured characterization for 37 distinct fishing métiers.
• Includes multiple classification dimensions: season, fishing area, depth, and sediment type.
• Explicitly identifies unvalidated métiers for clarity.
• Released under a permissive CC-BY-4.0 license.

Limitations

• Dataset is very small at 13.5 KB, indicating limited scope.
• Row count and column-level documentation are unknown.
• Description metadata is limited; actual data quality requires manual inspection after download.
