CORY 3/93: North West Groundfish Survey Catch and Biological Data

Irish Sea and Bristol Channel fisheries survey data collected from 04/03/1993 to 29/03/1993 by Cefas. The survey recorded station, catch, length, and biological data for 76 species across 141 stations using a 4m beam trawl. Data supports EU regulations and ICES research programs, with additional aims to collect benthic, litter, water quality, and acoustic data.

Use Cases

• Calculate abundance indices for groundfish species based on catch and station data.
• Analyze species composition and biodiversity across 141 sampling stations.
• Model fish population dynamics using length and biological data for selected species.
• Correlate environmental factors like water temperature and salinity with species distribution.
• Support stock assessments and regulatory reporting for EU data requirements.

Strengths

• Survey operations were undertaken on 141 stations, providing spatial coverage.
• 76 different species were caught on this survey, indicating taxonomic breadth.
• Data collection includes multiple data types: station, catch, length, and biological data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified; the last metadata update was 2026-06-11.
