The spokesperson said after receiving reports of the incident east of Port McDonnell, the department launched an investigation.

“The cause has not yet been confirmed, but early indications from water testing are that low salinity, caused by recent heavy rainfall, is the most likely reason for the fish kill,” the spokesperson said.

‘PIRSA has collected tissue samples to rule out waterborne diseases and tests are being carried out.

‘In general, fish kill events can be caused by a variety of causes, including environmental factors such as temperature, rainfall (or lack thereof) and water quality, including salinity or oxygen levels, or by disease or pollutants.’

Low salinity could be to blame for the mass stranding, according to the Department of Primary Industries and Regions South Australia

PIRSA has reminded people that if they notice anything ‘unusual relating to dead or dying fish’ anywhere on the coast or in South Australia’s waterways, they should call FISHWATCH on 1800 065 522.
