Baited Underwater Video Deployments for Piscivorous Fish, 37 Hours of Footage

Baited Remote Underwater Video Systems (BRUVS) were deployed as a non-lethal method to sample larger piscivorous fish species that are under-sampled by trawl surveys. The project was conducted by Cefas from January 2012 to January 2014, resulting in 18 deployments and 37 hours and 23 minutes of recording time. The data likely contains video footage and associated metadata from these deployments.

Use Cases

• Assess the abundance and diversity of large piscivorous fish based on video observations.
• Compare the effectiveness of BRUVS versus trawl surveys for monitoring specific fish species.
• Analyze fish assemblage behavior in reef or deep-water habitats based on the non-lethal sampling method.
• Develop computer vision models for automated fish species identification from underwater video footage.

Strengths

• Provides 37 hours and 23 minutes of underwater video footage for analysis.
• Covers a defined project period from January 2012 to January 2014.
• Represents 18 distinct BRUVS deployments, offering multiple sampling events.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• The geographic scope of the 18 deployments is not specified in the provided metadata.
