Eastern Irish Sea Groundfish Catch Data from 1990 Silver Star Surveys

Catch data from two 1990 groundfish surveys conducted in the eastern Irish Sea aboard the vessel Silver Star. Numbers at length by centimetre for main commercial fish species and station positions by area are recorded. The data was collected by the Government Digital Service as part of a survey series running from 1976 to 1991.

Use Cases

• Analyzing species length distributions based on the recorded numbers at length by centimetre.
• Studying spatial distribution of commercial fish based on recorded station positions by area.
• Modeling historical fish population trends using catch data from a defined time series.
• Comparing catch composition between the two 1990 survey cruises using the included summary table.

Strengths

• Data originates from a defined survey series conducted over a 15-year period (1976-1991).
• Includes specific catch data for two distinct cruises (01/90 and 02/90).
• Records numbers at length by centimetre, providing detailed biological measurements.

Limitations

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