Information current as of 14 February 2020

Dear Members and friends,
The Department of Health (DoH) has extended its warning regarding the toxic Alexandrium algal bloom in the Swan and Canning rivers. DoH is advising people not to eat fish, crabs or shellfish collected from within the following waterways:
  • the Swan River – from Pelican Point, Crawley to the South of Perth Yacht Club, Applecross and upstream to Meadow Street Bridge, Guildford (this includes the commonly known areas of Matilda Bay, Perth Waters, Elizabeth Quay, Barrack Street Jetty, Claisebrook Cove, Maylands Yacht Club, Ascot Waters, Hind Reserve, Riverside Gardens, Garvey Park, Sandy Beach Reserve, Point Reserve, Kings Meadow and Fish Market Reserve)
  • the Canning River – from the South of Perth Yacht Club and upstream to Kent Street Weir (this includes commonly known areas of Canning Bridge, Mt Henry Bridge, Salter Point, Shelley Bridge, Riverton Bridge, and Castledare).
Swan River, extending from Pelican Point to Como Jetty and upstream to Tonkin Highway Bridge, or within the Canning River, extending from the South of Perth Yacht Club to Como Jetty and upstream to Kent Street Weir. A map of the impacted area is attached.

Alexandrium toxins can cause paralytic shellfish poisoning and cooking will not destroy these toxins.

Please see the latest DoH media statement at

The Department of Biodiversity, Conservation and Attractions continues to conduct weekly water quality monitoring at an increased number of sites to track the extent of the bloom. We are also testing mussels and crabs for the Alexandrium toxin. DoH and local riverfront councils have arranged for health warning signs advising against crabbing, shellfish collection and fishing to be erected at key riverfront locations including jetties, boat ramps and key accessible foreshore areas within the affected region. It should be noted that swimming and other aquatic recreational activities on the Swan and Canning rivers are not impacted by the algal bloom, but as a general rule swimming should be avoided in areas of discoloured water.

Further information is provided in detailed FAQ’s available at to share with your members. Please call me if you have any further questions. We will keep you informed on this matter.
