Brief description This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2023 project "Eastern Grey Nurse Shark population abundance and trend". For specific data outputs from this project, please see child records associated with this metadata. -------------------- The eastern population of grey nurse shark, Carcharius taurus, is listed as Critically Endangered under the EPBC Act 1999, and a strategy to ensure recovery was implemented in 2002 with the development of the first recovery plan. The recovery plan updated in 2014 identifies priorities that require ongoing research that form the basis of this proposed project. This includes research to refine the abundance and trend estimate for the eastern Australian population of grey nurse shark and examine the potential for range expansion into Victorian waters. This will add value to recent age and growth estimates and examine epigenetic ageing of juveniles. Such information is important to inform the assessment of current conservation arrangements such as spatial closures. Outputs • Tissue samples and extracted products from juvenile grey nurse sharks [dataset] • Final project report [written]
