Pollack fish fitted with acoustic tags emit coded signals detected by seabed receivers. The data tracks movement, habitat choice, and mortality for a species experiencing a 72% decline in commercial landings over 20 years. The dataset is part of the Pollack Fisheries Industry Science Partnership (FISP) and originates from the Government Digital Service via the eu_open_data platform.
Use Cases
- Estimate mortality rates based on uncharacteristic absences of tagged fish.
- Identify important habitats for pollack, particularly during spawning seasons.
- Analyze migration patterns based on acoustic tag detection data.
- Assess population dynamics and life history traits for fisheries management.
Strengths
- Data addresses a species with a documented 72% decline in commercial landings over the last 20 years.
- Acoustic telemetry provides continuous, uniquely coded signals for individual fish tracking.
Limitations
- Row count, file formats, and column-level documentation are unknown.
- Last update date is unknown; freshness unverified.
- Data may reflect geographic bias inherent to the UK and European receiver network.
Provenance
