Aquatic pests
Aquatic pests are exotic fish, plants and animals (crabs, molluscs, invertebrates), particularly noxious species. These are non-native to Australia and found in:
- freshwater
- estuaries
- marine environments.
Aquatic pests damage the natural balance of our environment. They also:
- compete with native species that are important to our economy and conservation
- ruin the attractiveness and social enjoyment of aquatic areas
- foul aquaculture and industrial infrastructure
- pose serious health risks.
Manage aquatic pests
