Roebuck Bay has been experiencing worsening blooms of the cyanobacteria, Lyngbya majuscula. This is concerning because fish avoid Lyngbya blooms which can reduce the available catch and large blooms can suffocate the seagrass meadows that dugongs and green turtles rely on as their main food source. Juvenile fish, prawns and invertebrates that hide in the leafy meadows can be suffocated too, which can affect migratory shorebirds who feed on them.
This presentation helps us to understand the risks, possible causes and actions that the community and management authorities can take to try to reduce Lyngbya blooms which are a serious threat to Roebuck Bay’s extraordinary marine biodiversity. To download the presentation »
