Validated Fishing Métiers for Portuguese Waters, 2014-2023

Portuguese waters contain a list of 28 validated fishing métiers, defined by gear and target species. The dataset, authored by Pedro Leitão, includes percentages of hauls across variables like season, fishing area, depth, and sediment type from 2014 to 2023. It is a small dataset of 35.7 KB, published under a CC-BY-4.0 license.

Use Cases

• Characterizing fishing activity patterns based on gear type and target species.
• Analyzing seasonal fishing effort distribution based on the year and season variables.
• Modeling habitat use by fisheries based on depth and sediment type data.
• Assessing regional fishing pressure based on the fishing area variable.

Strengths

• Defines 28 distinct fishing métiers validated for scientific use.
• Covers a 10-year time range from 2014 to 2023.
• Includes multiple characterization variables: year, season, fishing area, depth, and sediment type.
• Data is quantified with percentages of hauls for each variable level.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (35.7 KB), indicating limited scope.
