This record provides an overview of the scope and research output of NESP Marine Biodiversity Hub Project A1 - "Northern Australian hotspots for the recovery of threatened euryhaline species". For specific data outputs from this project, please see child records associated with this metadata.

Euryhaline elasmobranchs represent over half of the EPBC-listed threatened sharks and rays, with northern Australia of national importance for this threatened species community. Critical information gaps remain, limiting the implementation of Recovery Plan objectives. This project will fill many data gaps through the application of acoustic telemetry, traditional and advanced molecular research (population genetics and close-kin mark-recapture), life history studies and Indigenous knowledge and education. End-users, primarily the Department of the Environment, state and territory fisheries and wildlife agencies, and Indigenous organisations, will be provided with information necessary to improve management and facilitate recovery of these threatened species, focusing on three themes: (1) Monitoring and understanding euryhaline species; (2) Indigenous partnerships for management of euryhaline species, and; (3) Knowledge for the reassessment of river shark status. Planned Outputs • Updated assessment of river shark status • Manuscripts on ecology and status relevant to the management of threatened euryhaline species • Manuscripts on optimal design of acoustic receiver arrays and statistical methods for estimating mortality • Threatened marine species education package for Indigenous communities • Media releases around key field and engagement activities • Data and information outputs of this project will include distribution, extent of occurrence and area of occupancy estimates for key marine species, Indigenous knowledge on key species distribution and occurrence, mortality and survivorship data on key species, the first data on river shark age determination (an essential component of understanding demography), molecular data on population structure and population connectivity of key species, and lower population size estimate for Glyphis garricki. Data will be housed on appropriate explorable databases and made fully available to DOE • Refining the identification of biologically important areas (BIAs) within the NT and WA for threatened euryhaline elasmobranchs (using published BIA protocols)
