Southern North Sea Longline Fisheries Catch and Survival Data 2019/20

Fisheries catch data from a 2019/20 project in the southern North Sea. The dataset likely contains positional information, soak times, hook counts, and length distributions for all species, with additional release data for electronically tagged thornback rays. This work was carried out under the Fisheries Science Partnership programme by the Government Digital Service.

Use Cases

• Modeling seasonal catch rates based on recorded positional information and soak times.
• Analyzing catch composition and length distributions for all discarded and retained fish species.
• Assessing vitality and post-release survival of thornback ray based on electronic tagging data.
• Studying the relationship between fishing effort (hooks/baths) and catch outcomes.

Strengths

• Data collection includes multiple dimensions: spatial, temporal, operational (soak times, hooks), and biological (lengths, sex, maturity).
• Focus on a specific commercially important species (thornback ray) with detailed electronic tagging for survival studies.

Limitations

• Row count, column definitions, and file formats are unknown, limiting suitability assessment.
• Last update date is unknown; freshness unverified.
• Column-level documentation is absent; field semantics must be inferred after download.
