Australia’s aquatic environments have been under increasing pressure from introduced plant and animal species including the loss of native species and changes in ecosystem structure.
In most states and territories, legislation to protect Australia’s aquatic species and environment also contains provisions for the control of noxious or non-indigenous plants and animals. For example, the Queensland Fisheries Act 1994 contains provisions for the management of noxious and non-indigenous fishes in Queensland waters. Noxious fish include European carp (Cyprinus carpio), piranhas (all species of the genera Serrasalmus, Pygopristis, Pygocentrus), tilapia and walking catfish. Heavy fines (up to $150 000) can be imposed on anyone having noxious fish in their possession without a permit or for releasing these fish into the wild. Guilty persons can be charged the costs of eradication.
In association with legislative measures there are many pest management programs under way. The following examples outline some of the successes to date in reversing the impact of introduced species.
