Stop the spread of aquatic pests
Recreational boat users and fishers
- Prevent unwanted hitchhikers – Boats have many niche areas where marine pests can accumulate. Keep your moored boat free of fouling by applying a suitable antifouling paint, and cleaning and renewing it when persistent fouling occurs.. Check, clean and dry trailer boats and gear (including anchors, ropes and chains) before you move between waterways.
- Dispose of any debris found on fishing and boating gear away from the waterway.
- Avoid recognised infestation areas, e.g. marked Caulerpa taxifolia (Caulerpa) closures. Anchors, propellers and other boating and fishing gear can pick up pests or weed fragments and spread them to new areas.
Ornamental fish enthusiasts
- Don’t dump that fish!
- Keeping fish is fun, but it is important to make sure that living things in your aquarium or home pond are kept away from our oceans and waterways.
- Take care when cleaning aquaria to prevent water, aquarium fish, aquarium plants, ‘live rock’ or other waste materials ending up in your local waterways (including a drain, creek or ocean).
- Give unwanted aquarium fish or plants to friends or an aquarium shop, or dispose of them humanely by putting them to sleep in an ice-slurry then freezing them.
Oyster and marine fish farmers
- Prevent accidental escapes – comply with aquaculture permit conditions designed to prevent the escape of fish (e.g. screened water outlets).
- Culture only those species listed on your aquaculture permit - don’t experiment with non-native species.
- Learn to recognise significant existing and potential aquatic pests. See freshwater fish pests & marine pests.
- Photograph and report suspected pests to the DPI Aquatic Biosecurity Unit
