Primary Industries and Regions South Australia have advised that the Pacific Oyster Mortality Syndrome virus has been detected in feral pacific oysters in the Port River.
At this stage POMS has not been detected in SA oyster farming areas.
The POMS virus was detected after samples were taken during a routine surveillance of the Port River area and additional testing of these samples carried out by the Australian Animal Health Laboratory confirmed the results.
To reduce the risk of POMS spreading, PIRSA has implemented a ban on the removal of oysters, mussels, cockles from the river until further notice.
They should not be taken for any purpose including bait or berley.
Fishers and boat operators are asked to help stop the spread of POMS by ensuring they follow cleaning steps before their vessels leave the river for other parts of the state.
Operators need to ensure vessel hulls are clean and plants and animals from fishing and boating equipment and clothing are removed.
Where possible boats and equipment need to be washed with light household detergent and rinsed with tap water without letting the water drain into waterways, and importantly dry everything completely before moving to another waterway.
PIRSA will continue to work with the oyster industry, recreational fishers, and owners of vessels to minimise the risk of the virus spreading.
