NESP MaC Project 3.11 - Multi- fishery collaboration to assess population abundances and post release survival of threatened sawfish in northern Australia, 2023-2026 (CSIRO, CDU)
This record provides an overview of the NESP Marine and Coastal Hub study - Project 3.11 - Multi- fishery collaboration to assess population abundances and post release survival of threatened sawfish in northern Australia. For specific data outputs from this project, please see child records associated with this metadata.
To improve sawfish reporting and obtain an estimate of sawfish abundance and stock structure, a large-scale collaborative project is proposed between industry, State and Commonwealth agencies and lead research institutions to gather tissue samples from across northern Australia. The project will have a focus on developing trust between research and the commercial fishing industry that will achieve the following:
- Industry led reporting and sampling programs will be established throughout Australia’s northern fisheries.
- Tissue samples will be used to assess sawfish abundance and stock structure using Close-Kin Mark-Recapture (CKMR).
- Estimates of post-release survival will be obtained from satellite tagging and improved reporting.
- Data on abundance and post release survival will be used to assess the sustainability of sawfish bycatch.
The research also aims to improve reporting of sawfish along with other EPBC listed species in northern Australian fisheries. If enough tissue samples are collected, close kin mark recapture will enable estimates of adult population size for four species of sawfish. Post release survival and abundance estimates will be used to determine the sustainability of sawfish captured as bycatch in state, territory and Commonwealth Fisheries. Improved estimates of bycatch, population connectivity, adult abundance and post release survival were identified as the highest research priorities in the Sawfish and River Shark multispecies recovery plan.
Within Australia, three out of the four occurring species are listed as Vulnerable and Migratory under the EPBC act (Pristis pristis, P. zijsron and P. clavata). The fourth Australian species, narrow sawfish (Anoxypristis cuspidata) is listed as a Migratory species. Both A. cuspidata and P. pristis are currently under nomination to be up-listed to Endangered under the EPBC act. The Freshwater Sawfish Pristis pristis is also listed in the Threatened Species Strategy - 100 priority species for fish.

- Purpose
- Project aims and objectives: • Build trust between research and the fishing Industry in Northern Australia with respect to the bycatch and management of interactions with threatened species • Improved reporting of sawfish (and other TEPS) within northern Australian gillnet and trawl fisheries • Industry led tissue sampling and data collection that will enable population structure and adult abundance of all four Australian sawfish species to be determined in populations were sufficient tissue samples are collected. • Post release survival estimates of sawfish captured as bycatch in commercial gillnet and trawl fisheries • Estimate the sustainability of sawfish bycatch and provide industry and managers with the data required to make decision on acceptable levels of bycatch.
