North Sea Cod and Plaice Tagging Data for Climate Impact Studies

Tagging data for 22,573 North Sea cod (1961-2015) and 53,489 plaice (1957-2005) includes information on fish location, maturation, sea surface temperature, length, weight, and tagging/recapture times. The dataset was generated for the EU H2020 Pandora project and includes both conventional marker-ID tags and, for cod from 1999 onward, electronic Data Storage Tags (DSTs). It supports analysis of how environmental factors like temperature affect fish fertility and population dynamics.

Use Cases

• Modeling changes in cod or plaice fertility based on recorded sea surface temperature (SST)
• Analyzing population dynamics and movement patterns using tagging and recapture location data
• Studying growth and maturation trends across decades using length and weight measurements
• Comparing fish behavior and data quality between conventional marker tags and electronic Data Storage Tags (DSTs)

Strengths

• Contains a large sample size with 22,573 cod and 53,489 plaice individual records
• Covers a long temporal range, with data collected from 1957 to 2015
• Includes multiple measurement types such as location, SST, length, weight, and maturation status

Limitations

• Column names and specific data schema are not provided in any source description
• Key metadata such as license, author, and precise row count are consistently listed as unknown or null across all platforms
• The dataset's freshness is uncertain as the last update date (2026-06-11) appears to be a future placeholder
