ViewpointMarine biosecurity: The importance of awareness, support and cooperation in managing a successful incursion response

Shipping is almost certainly the most prevalent human-mediated transport vector for non-indigenous species (NIS) within the marine environment. The Royal Australian Navy (RAN) has long acknowledged the importance of sound environmental management and in recent years has taken a proactive approach to addressing risks associated with marine biosecurity. primarily as a result of biofouling on Navy vessel returning from overseas operations. This paper describes two case studies that highlight the effectiveness of the RAN marine biosecurity management framework in identifying an unwanted marine species on Navy vessels, and the successful biosecurity management program that ensued. In particular, the early detection and identification of a suspect NIS, the quick response to the discovery and the collaborative approach adopted between the RAN and the Government regulatory agency (Western Australian Department of Fisheries) charged with coordinating the incursion response serves as a model for how future incursion responses should be reported and managed.

► Perna viridis detected on Royal Australian Navy (RAN) vessels in Western Australia. ► We describe the events up to and following the discovery of this unwanted species. ► Early detection and quick response to the discovery ensured a successful incursion response. ► Close collaboration between the RAN and the regulatory agency also crucial to success. ► These case studies serve as a model for how future incursion responses should be managed.
