Aquatic Biosecurity Threats

There are many pests and diseases that could cause serious impacts if introduced to Tasmanian waters. Some examples of aquatic pests and diseases that pose a threat to Tasmania include:
  • Didymo is a freshwater alga not yet present in Australia. It takes just one cell in a single drop of water to be spread between waterways. The cells multiply quickly to form massive blooms that completely smother the stream or lake bed. These algal clumps adversely affect water quality, aquatic invertebrates and fish stocks, and are a hazard for hydro generation, irrigation and recreation.
