Spotted Tilapia update
Spotted tilapia were recently found in Far North Queensland in the Walsh River (north of Chillagoe) and near Bruce Weir (near Dimbulah, west of Mareeba).
If you see or catch a spotted tilapia in the area, take a photo and report it online or call Biosecurity Qld on 13 25 23.
Tilapia were first introduced into Australia in the 1970s as ornamental fish and are now regarded as one of the greatest threats to Australia's native biodiversity. Females carry juveniles and eggs in their mouths, and these can survive for a considerable time after the adult dies. Therefore, new incursions can occur when live or dead fish are released into a waterway.
Tilapia is a restricted noxious fish under the Biosecurity Act 2014.
