Recreational Shark Fishing Tournament Landings and Dart Tag Records

4265 biological samples from shark landings and 4138 tagging events with 97 recaptures, collected by Fisheries and Oceans Canada. The dataset combines tournament landings records from 1993 to 2022 with a dart tag database active from 2006 onward. Information is focused primarily on Blue Sharks captured at recreational tournaments.

Use Cases

• Analyze biological sampling data from 4265 landings to study Blue Shark population demographics.
• Model recapture probability and movement patterns using 4138 tagging and 97 recapture events from the dart tag database.
• Examine long-term trends in recreational shark fishing by correlating landings data from 1993-2022 with annual tag updates.

Strengths

• Contains 4265 biological samples from shark landings, providing a substantial sample size for analysis.
• Includes 4138 tagging events with 97 recaptures, enabling mark-recapture and movement studies.
• Covers a long temporal range, with landings data spanning 30 years from 1993 to 2022.

Limitations

• Data is focused primarily on Blue Sharks, limiting analysis of other shark species.
• The dart tag recapture rate is low (97 recaptures from 4138 tags), which may constrain certain population models.
• Specific column names and data structure are not provided in the input, requiring initial exploration.
