These three tilapia species were introduced into Australia through the aquarium trade. They are extremely hardy fish with highly efficient breeding strategies (including mouthbrooding), simple food requirements and flexible habitat preferences.
There are no existing populations of tilapia in NSW. However, they have established successful breeding populations at several sites in Queensland, Victoria and Western Australia, and have impacted native fish populations through competition for food and space.
It is usually extremely difficult to eliminate pest fish once they have become established in the wild. It is therefore vital to prevent noxious pests such as tilapia from entering or spreading further in our waterways.
