Marine fish kill in Jurien Bay Marina

Update to Fisk Kill Notification
– 28 September 2019 at 2pm

DPIRD advise that results of laboratory tests show there was no phytoplankton at densities of concern, in the water samples collected from the fish kill site.

No further dead finfish have been seen since last Saturday, but a Fisheries officer has reported seeing dead molluscs and crabs during the past week.

Dissolved oxygen readings taken this week still indicate very low levels and, because readings taken at the time of the fish kill showed extremely low levels, this remains the most likely primary cause of the initial fish kill.

Report any fish kills to FishWatch 1800 815 507

DPIRD Fish Kill Notification
- 13 September, 2019

Investigations are underway following the report of a fish kill at the Jurien Bay Marina, where large numbers of dead fish from a range of species have been found.

Department of Primary Industries and Regional Development officers are investigating the event, to gather information and assess the extent of the fish kill. They have also gathered suitable fish and water samples for laboratory testing.

The Shire of Dandaragan and Department of Transport have been communicating within the local community. Affected beaches have been closed, signs erected and there are plans to take water samples for bacterial analysis. Dissolved oxygen levels within the marina are known to be very low at present.

Dead fish are also being removed from affected beaches.

Updates will be issued, when further information is available. In the mean-time people are reminded to stay safe around fish kills.

We urge people to stay safe by following 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.
  • Anyone who has handled dead or dying fish and experiences any inflammation on their hands around any cuts or abrasions should see a doctor.

Fish kills should be reported to our FishWatch 24-hour hotline on 1800 815 507.

The Department of Primary Industries and Regional Development (DPIRD) is responsible for responding to fish kill events that occur in ocean environments.

The Department of Water and Environmental Regulation manages investigations on fish kills that occur in estuaries, rivers and naturally occurring inland water bodies.

In both circumstances, DPIRD’s laboratories carry out testing of any fish samples assessed as suitable for that purpose to determine if diseases are present. This can take some time and it may not be possible to identify a single definitive cause, but every effort is made to establish probable factors.
