Australian Ocean Data Network hosts a dataset on Draughtboard Shark tagging and recapture from January 2000 to January 2007. Sharks were tagged during rock lobster catch sampling trips around southwestern and eastern Tasmania and in the Crayfish Point Reserve. For each shark, sex, total length, and clasper length for males were recorded.
Use Cases
- Analyze shark growth rates based on recorded total length and recapture data.
- Study sex-specific biological characteristics based on recorded sex and clasper length for males.
- Model shark movement and site fidelity based on tagging and recapture locations around Tasmania.
- Assess shark population demographics in relation to rock lobster fisheries activity mentioned in the description.
Strengths
- Data collection spanned seven years from January 2000 to January 2007.
- Records include multiple biological measurements: sex, total length, and clasper length for males.
- Sampling covered multiple geographic areas: southwestern and eastern Tasmania and the Crayfish Point Reserve.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic and source bias inherent to fishery-dependent sampling.
