A 2023-2026 collaborative project led by CSIRO and CDU aims to assess four threatened sawfish species in northern Australia. Planned outputs include spatial catch data, tissue samples for genetic sequencing, and a final technical report with policy recommendations. The research focuses on estimating population abundance via Close-Kin Mark-Recapture and post-release survival via satellite tagging.
Use Cases
- Estimating adult population size for four sawfish species based on tissue samples and Close-Kin Mark-Recapture methods described.
- Assessing post-release survival rates of bycaught sawfish based on satellite tagging data mentioned in the description.
- Evaluating the sustainability of sawfish bycatch in northern Australian fisheries based on abundance and survival estimates.
- Improving reporting rates for EPBC-listed species in commercial fisheries based on the industry collaboration framework.
Strengths
- Project involves a large-scale collaboration between industry, state, and Commonwealth agencies, suggesting broad data collection.
- Focuses on four specific sawfish species, three listed as Vulnerable and Migratory under the EPBC Act.
- Planned outputs include multiple data types: spatial catch datasets, genetic sequencing data, and a final analyzed report.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
