A collaborative new research project will bring together fisheries experts from across Australia and abroad to work jointly on re-establishing wild populations of the endangered native Macquarie Perch.
The three-year project will conduct dedicated research to ‘crack the code’ on captive breeding of the species, meaning fisheries experts will be able to produce and release Macquarie Perch using hatchery broodstock, rather than capturing wild adult fish every season.
The project, led by the Federal and Victorian Governments, features 12 partners across government, universities and community, including Victorian Fisheries Authority (VFA), Fisheries Research and Development Corporation (FRDC), NSW Fisheries and the North East and Goulburn Broken Catchment Management Authorities.
This important work will also be driven by research partners including Deakin University, University of the Sunshine Coast, Monash University, Arthur Rylah Institute and the Norwegian Institute of Aquaculture Research, as well as the Goulburn Broken Catchment Management Authority.
Macquarie Perch were once abundant in south-eastern Australia but a range of factors, including barriers to fish migration and loss of habitat, have restricted populations to just a handful of locations. Breeding currently relies on annual collection of broodfish from the wild, with experts having been unable to replicate environmental conditions for broodstock to thrive in hatcheries over several breeding seasons.
This dedicated research project will examine nutrition, hormones, the timing of breeding and other factors to understand how to consistently produce fingerlings for stocking – boosting the ongoing work to save the Macquarie Perch from extinction.
Since 2022, the VFA’s Snobs Creek hatchery has produced more than 185,000 Macquarie Perch – including 40,000 released in Victoria’s north-east earlier this year.
