Eastern Irish Sea groundfish surveys conducted from the vessel Silver Star in 1983. The data records numbers at length by centimetre for main commercial fish species and includes station positions by area. A summary table for two cruises contains catch data for all other species.
Use Cases
- Analyze historical fish population size structure based on numbers at length data
- Map species distribution and abundance based on recorded station positions
- Study changes in commercial fish stocks over time as part of a longer time series
- Compare catch compositions between different survey cruises in 1983
Strengths
- Data originates from a standardized survey series conducted from 1976 to 1991
- Includes specific catch data for two cruises (02/83 and 03/83)
- Records station positions by area, enabling spatial analysis
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Data may reflect temporal bias inherent to the 1983 survey year
