Aquatic pests

Unwanted freshwater pests like the invasive catfish and hornwort pose a serious threat to our rivers, streams and lakes.

Once in a waterway these pests can spread rapidly and destroy the environmental, recreational and aesthetic values of our waterways.

Find out more on the rules that apply when using the region's waterways and the need to self-certify that your vessel and trailer is free from pest weed and fish when using the region's boat ramps.
