Thanks to Trevor Daly, Maryrose Antico, Gabrielle Holder, Jillian Keating and Erin Lake from the NSW DPI Fisheries Threatened Species Unit along with Katherine Cheshire (NSW DPI Fisheries Freshwater Research) who initiated the project, provided guidance on its content and reviewed the document. The report benefited from consultation with a range of people (in no particular order) who shared their expertise on the target species: including Lachie Jess and Matt McLellan (Narrandera Fisheries Centre, NSW DPI Fisheries), Mathew Birch (Aquatic Science and Management), Mitch Turner (Grafton Fisheries Centre, NSW DPI Fisheries), Luke Pearce (NSW DPI Fisheries), Chris Brauer and Leslie Morrison (Flinders University), Cory Young and Ruan Gannon (Aquasave‒NGT) and Peter Unmack (University of Canberra). We thank all involved for providing their hard-earned knowledge to help conserve these threatened species. Acknowledgement of the Traditional Owners of the Murray–Darling Basin We respectfully acknowledge the Traditional Owners, their Elders past, present and emerging, their Nations of the Murray–Darling Basin, and their cultural, social, environmental, spiritual, and economic connection to their lands and waters. i NSW conservation translocation handbook TABLE OF CONTENTS ACKNOWLEDGEMENTS ............................................................................................................................ i 1.
