Eastern Irish Sea Groundfish Catch Data from 1991 Survey

Eastern Irish Sea groundfish survey data from 1991. The dataset records numbers at length by centimetre for main commercial fish species and includes station positions by area, with a summary table for all other species. The survey was conducted by the Government Digital Service using a Boris Goshawk trawl towed for an hour.

Use Cases

• Modeling fish population length distributions based on recorded numbers at length by centimetre.
• Analyzing spatial distribution of commercial species based on recorded station positions by area.
• Assessing species composition in the eastern Irish Sea based on the summary table for all other species.
• Studying historical trawl survey methodology based on the described use of a Boris Goshawk trawl.

Strengths

• Data is from a specific, documented survey year (1991).
• Includes a summary table for non-commercial species, providing broader ecological context.
• Station positions are recorded by area, enabling spatial analysis.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
