Current threatened species projects

The NSW Department of Primary Industries is involved in numerous research, conservation management and habitat restoration projects which contribute to the well being of threatened species.

Here you will find some information on some of the programs that the Department is running or is contributing to. Other organisations such as local councils, local land services, universities, fishing groups, landholders and conservation groups are also critical to the delivery of some of these programs.

If you are involved in threatened species management or research, or have an idea of a local project that you would like to tell the Department about, we would like to hear from you! Please send us an email to fisheries.threatenedspecies@dpi.nsw.gov.au

Stage two of a Murray Crayfish conservation stocking program has been completed with over 200 Murray Crayfish relocated in the Murray River to more poorly populated areas downstream.

Murray Crayfish are a native freshwater species endemic to the Murray-Darling Basin. They are the world’s second largest freshwater crayfish, growing to three kilograms in weight and can be easily identified by their large white claws and spiny green and brown abdomens. We’re running this conservation translocation program because Murray Crayfish have very low dispersal abilities and occupy small home-ranges, which means they struggle to recolonise areas where their population has declined.

Continued monitoring will be undertaken to determine the success of the project.

The translocation project is a collaborative project with DPI and Aquasave – Nature Glenelg Trust, with funding support from the NSW Recreational Fishing Trust.

DPI is continuing its conservation stocking program for Silver Perch and Trout Cod in NSW, with fish produced at the Narrandera Fish Hatchery. Between 2016 and 2018 a total of 120,000 Silver Perch fingerlings were released into the Namoi River between Gunnedah and Narrabri. Between 2015 and 2017 over 46,000 Trout Cod were released into the Upper Macquarie River.

A two year Murray Crayfish conservation stocking program commenced, with 200 Murray Crayfish being moved from an area where they are abundant to a site downstream in the Murray River which has suffered a significant decline in the local population.

Murray Crayfish are an iconic Australian species and are an essential part of the Murray Darling Basin ecosystem. They were once widespread throughout the Murray and Murrumbidgee catchments however have declined in range and distribution due to a range of environment factors, including a widespread hypoxic blackwater event which occurred during 2010 and 2011. As a result, Murray Crayfish are now listed as ‘vulnerable’ in NSW.

This is the first time a stocking program to boost the population of Murray Crayfish has been conducted in the Murray River in NSW. Another 200 Murray Crayfish will be released to the site next year along with continued monitoring to determine the success of the project.

The translocation project is being run by DPI in collaboration with Aquasave – Nature Glenelg Trust, the NSW Recreational Fishing Trust and local fishing clubs

DPI Research staff confirmed that Macquarie Perch in a waterway near Oberon are breeding. This has confirmed that our conservation stocking of over 19,000 captive bred fish have established a new breeding population of the species in NSW. Surveys also confirmed that Macquarie Perch adults stocked into the Bolong River are also persisting. This project has taken over 10 years of effort to achieve this significant result.
