Stereo Underwater Fish Survey Videos from St. Lucia, 2019

87 one-hour stereo-Baited Remote Underwater Video (BRUV) samples were collected off the northwest coast of St. Lucia in February 2019. The survey, conducted by Cefas under the Commonwealth Marine Economies Programme, recorded demersal fish communities to a maximum depth of approximately 50 meters. Each station also recorded light and temperature data using a HOBO logger.

Use Cases

• Training object detection models for fish species based on the stereo-BRUV video footage.
• Analyzing fish abundance and community composition based on the classified video data.
• Studying the relationship between environmental factors (light, temperature) and fish presence based on the HOBO logger data.
• Calibrating and testing stereo-video measurement techniques for marine science.

Strengths

• 87 distinct one-hour video samples provide a substantial observational record.
• Stereo-video setup with calibrated cameras enables accurate size and distance measurements.
• Environmental data (light, temperature) is included alongside video, captured with a HOBO logger.
• Survey methodology and analysis are documented in a peer-reviewed publication (DOI: 10.1002/aqc.3518).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for any associated tabular data is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to a single two-week survey in one region.
