The introduction of marine species outside their natural geographic ranges can have serious consequences for native ecosystems, including declines in biodiversity and the loss of socio-economic value. For marine pests, efforts to prevent and manage these impacts have mainly focused on understanding their origins and preventing their introduction, primarily through managing ship biofouling and ballast water. However, when new species do appear, there are limited tools available for early detection, preventing establishment, stopping their spread, and minimising their impact on local ecosystems. In contrast, terrestrial biosecurity has a broader range of tools for managing and eradicating introduced species, but similar approaches have not been developed for marine pests and diseases. Thanks to recent advances in technology and research, new tools and methods have emerged, offering management agencies a variety of options for managing marine pest species. These include cost-effective molecular tools for monitoring and surveillance, as well as species-specific traps that could improve containment and removal efforts. In this talk, I will provide an overview of these recent advances and discuss future opportunities for marine pest management.
