CORY 4/95: 1995 Irish Sea and Bristol Channel Groundfish Survey

97 stations were sampled during a 1995 fisheries survey aboard the Corystes, catching 66 different species. The Centre for Environment, Fisheries & Aquaculture Science (Cefas) conducted this survey to create indices of abundance for EU data regulations and ICES research. Data includes catch, length, and biological information for selected species, alongside benthic, litter, water temperature, salinity, and acoustic measurements.

Use Cases

• Modeling fish population indices based on catch and length data mentioned in the description
• Analyzing species diversity and composition across 97 sampled stations
• Correlating biological data with concurrent environmental measurements like water temperature and salinity
• Supporting stock assessment and fisheries management as part of EU and ICES regulatory frameworks

Strengths

• Survey operations were undertaken on 97 stations, providing spatial coverage
• 66 different species were recorded, indicating biodiversity capture
• Includes multiple data types: station, catch, length, biological, benthic, litter, and environmental data

Limitations

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