1991 Eastern Irish Sea Groundfish Survey Catch Data

A 1991 survey provides numbers at length by centimetre for main commercial fish species in the eastern Irish Sea. Fishing was conducted using a Boris Goshawk trawl towed for one hour at recorded station positions. The dataset includes a summary table of catch data for all other species.

Use Cases

• Modeling historical fish population length distributions based on the recorded numbers at length.
• Analyzing spatial catch patterns based on the recorded station positions by area.
• Assessing species composition for commercial fisheries based on the summary table of all other species.

Strengths

• Provides specific numbers at length by centimetre for main commercial species.
• Includes spatial reference with recorded station positions by area.
• Contains a summary table for catch data of all other species.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a single year (1991), limiting temporal trend analysis.
