Introduction
Tilapia are listed in the top 100 of the world’s worst introduced species. They are listed as noxious in NSW and possession and sale of live tilapia is prohibited with penalties of up to $11,000. Tilapia is the common name given for fish from the genera Oreochromis, Sarotherodon, Serranochromis and Tilapia, all from the Cichlidae family.
These varieties of tilapia were previously traded in the aquarium industry. They are extremely hardy fish with highly efficient breeding strategies (including mouthbrooding), simple food requirements …show more content…
What are their impacts?
Tilapia have characteristics that allow them to easily establish in new areas and become dominant at the expense of native fish populations. These characteristics include simple food requirements, flexible habitat preferences and highly efficient breeding strategies.
Tilapia can dominate local fish communities, displacing local species. They may also have an effect on native fish through aggressive behaviour and competition for food and space. They are also known to occasionally prey on the eggs and fry of other fish.
Tilapia are capable of colonising degraded habitats in which other animals cannot survive. They may also contribute to habitat degradation, with nest building by Mozambique mouthbrooder males having the potential to damage aquatic vegetation and lead to increased turbidity.
What is I&I NSW doing?
Tilapia are listed as Class 1 noxious fish in all NSW waters under the Fisheries Management Act 1994. It is illegal to possess, buy or sell tilapia in NSW and heavy penalties of up to $11,000 apply. In addition, I&I NSW has the power to seize and destroy noxious
