AI Article Synopsis
- Early detection of invasive species in ports is essential, and this study developed a fast eDNA testing method for identifying the invasive seaweed Asparagopsis armata, with results available in just four hours.
- The methodology was trialed at four international Spanish ports while engaging with stakeholders, who provided feedback on its practical application.
- Despite a limited concern about biological invasions, stakeholders approved of the testing method, successfully detecting A. armata in three ports and suggesting improvements for broader use and detection of multiple species.
Article Abstract
Early detection of invasive species is crucial to deal effectively with biological invasions in ports, which are hotspots of species introductions. In this study, a simplified end-time PCR methodology conducted on eDNA from water samples was developed for rapid detection of the invasive seaweed Asparagopsis armata (four hours from water collection to result visualization). It was tested dockside in four international Spanish ports in presence of stakeholders, whose feedback was obtained to explore the real applicability of this biotechnology. Although biological invasions were not a main concern for them, results indicate a unanimous approval of the methodology by the stakeholders, having detected the presence of A. armata in three of the ports. Stakeholders suggested further developments for easier application of the tool and multiple species detection, to be adopted for the control of invasive species in ports.
