RESIDENTS have been urged to avoid swimming in the Myalup beach after reports of hundreds of fish killed in the area.

Department of Primary Industries and Regional Development received reports on October 15 that black bream, sea mullet and flat heads have been located dead on the beach.

Fish and water samples were collected from Myalup Beach and transported to Perth for analysis.

No evidence of infectious disease has been found as of yet.

According to the department, water sample analysis did not indicate a phytoplankton connection to the fish kill event.

Further water samples were subsequently collected from the Harvey Diversion Drain and are being analysed.

Residents are urged to follow the general Department of Health advice:

  • not to swim in areas of water with large numbers of dead and decomposing fish because they may contain high levels of bacteria and have an objectionable odour;
  • not to fish in water with large numbers of dead fish;
  • not to handle, collect, relocate or use dead fish for bait or consumption because of the risk of high levels of bacteria, and the potential for infection through handling or ingestion; and
  • not to allow pets and other animals to come into contact with dead or decomposing fish either in the water or on shore.

Updates will be issued when further information is available.

Fish kills should be reported to the Department of Primary Industries and Regional Development FishWatch 24-hour service on 1800 815 507.
