Swan River Algal Bloom

Following two consecutive years of significant Alexandrium blooms impacting recreational and commercial fishing in the Swan and Canning Rivers, the Department of Primary Industries and Regional Development (DPIRD), Department of Biodiversity, Conservation and Attractions (DBCA) and the Department of Health (DoH) have decided on a new management approach.


The new approach involves the installation of caution signage at various locations around the river advising against eating mussels or crab viscera/ stomach.


An example of this signage is below:



Caution signs have been placed at the following locations:

  • Claughton Reserve jetty;
  • Hinds Reserve jetty;
  • Katanning Street jetty;
  • Memorial Drive boat ramp; 
  • Bath Reserve foreshore and jetty;
  • East Street Maylands Yatch Club; and
  • Maylands boat ramp

Please see the Department of Biodiversity, Conservation and Attractions website for further information and updates.
