Anglerfish and Hake Survey in the Celtic Sea, 2004/05

One of ten beam trawl surveys investigating catches of anglerfish and hake (Merluccius merluccius) in the Celtic Sea and Western Approaches. The survey also examined bycatches of other species and tested an "environmental panel" designed to reduce bycatch of organisms and debris. The dataset was aggregated from the eu_open_data platform by the Government Digital Service.

Use Cases

• Analyze anglerfish and hake population distribution based on survey trawl data.
• Study bycatch composition and rates for non-target species.
• Evaluate the effectiveness of modified fishing gear, such as the 'environmental panel', for reducing bycatch.
• Model species interactions and ecosystem impacts in the Celtic Sea region.

Strengths

• Focus on a specific, ecologically important region: the Celtic Sea and Western Approaches.
• Explicitly designed to test a specific gear modification (environmental panel) for bycatch reduction.
• Part of a series of ten surveys, suggesting a structured data collection effort.

Limitations

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