Oyster testing could increase

Primary Industries and Regions SA will look at increasing the extent and frequency of testing in commercial oyster growing regions following the detection of the Pacific Oyster Mortality Syndrome in feral oysters in Adelaide’s Port River. 

PIRSA fisheries and aquaculture executive director Sean Sloan said testing from commercial growing oyster regions was continuing and further updates would be provided when the test results were available.

He said PIRSA continued to monitor and test oysters in the Port River and any other possible areas of risk.

“Surveillance and testing of the state’s commercial oyster growing regions has been in place since 2017, with over 2500 oysters tested,” Mr Sloan said. 

“This surveillance will continue, and as part of our POMS response PIRSA will review the frequency and extent of testing.”

SA Best Port Adelaide candidate Gary Johanson said he was concerned plans to dump spoil dredged from the Outer Harbour in Gulf St Vincent would “decimate” the oyster industry. 

“Dumping spoil taken from a known contaminated site and into the gulf is too dangerous and can cause POMS to spread,” he said.
