Making room for Macquarie perch

Making room for Macquarie perch

Macquarie perch, once widespread across the Murray Darling Basin, are now in danger of becoming extinct, due largely to riverbank erosion, the introduction of alien fish species and barriers to migration such as weirs and dams. In order to reintroduce a breeding population a site was needed with good habitat free from redfin and having only low numbers of trout. A small reach of the Retreat River near Bathurst was identified as suitable by staff from the Lachlan CMA and NSW DPI.
After successfully breeding fingerlings in captivity, researchers teamed up with the Central Acclimatisation Society (CAS) to release the fingerlings. The
site has only a low resident population of trout and the CAS have agreed not to include this site in their trout stocking program for the duration of the project. The fingerlings have been chemically marked, and will be monitored over coming years to check on their progress. For more information, contact Luke Pearce (NSW DPI) or Karl Schaerf (CAS).
