Tilapia have successfully invaded and dominated many aquatic habitats due to their highly efficient reproductive stragegy, simple food requirements and their ability to live in a variety of conditions. Unlike many native freshwater fishes, tilapia are able to retreat downstream into highly saline waters during drought and move back upstream when conditions improve. They affect native species when competing for habitat and food, behaving aggressively and disturbing plant beds when building nests.

It is important not to move tilapia from one waterbody to another as this is the main way they are spread. If you catch one, kill it in humanely and dispose of it away from the waterbody. Do not use tilapia as bait, live or dead. Please report tilapia sightings to the Department of Primary Industries and Fisheries.
