Marine Biosecurity Alert – Suminoe Oyster – Moreton Bay

The confirmed detection of the invasive Suminoe oyster (Magallana ariakensis) across numerous estuaries on the western side Moreton Bay has been assessed by the Consultative Committee on Introduced Marine Pest Emergencies (CCIMPE), and it has been determined that eradication is not technically feasible.

While we cannot eliminate this pest completely, we need your help to minimise the spread and impacts of the Suminoe oyster. The Suminoe oyster may be present on any hard structure including pontoons, wharfs, or boat ramps that you utilise. Biosecurity Queensland is actively mapping current detections and collaborating with stakeholders to develop appropriate management strategies.

Under Queensland biosecurity legislation, everyone has a General Biosecurity Obligation  (GBO) to help manage biosecurity risks.

The Suminoe oyster poses several risks, including:

·        Fouling of marine structures and disturbed areas

·        Competition with native species for habitat

·        Potential introduction of disease or parasites to commercial oyster operations

If you suspect that Suminoe oysters are growing on structures you utilise or notice unusual marine life in the areas you boat and fish, please contact Biosecurity Queensland.

If your vessel has been moored in an area for an extended period of time please follow the steps in the  National biofouling management guidelines for marinas, slipways, boat maintenance and recreational boating facilities for vessel cleaning and maintenance.

Please find relevant fact sheets and management guidelines attached.
