1989 Eastern Irish Sea Groundfish Catch Data from Silver Star Surveys

Catch data from two 1989 groundfish surveys conducted in the eastern Irish Sea aboard the vessel Silver Star. Numbers at length by centimetre are recorded for main commercial fish species, and station positions by area are included. A summary table contains catch data for all other species from cruises 01/89 and 02/89.

Use Cases

• Analyzing historical fish population size structure based on recorded numbers at length by centimetre.
• Mapping species distribution and abundance based on recorded station positions by area.
• Studying changes in commercial fish communities over time as part of a longer survey series from 1976 to 1991.

Strengths

• Data is part of a defined time series of surveys conducted from 1976 to 1991.
• Includes specific catch metrics for main commercial species and a summary for all other species.
• Survey methodology is described, specifying the use of a Boris Goshawk trawl towed for an hour.

Limitations

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