Text
The highly invasive quagga mussel was confirmed as present in Lower Lough Erne, which was the first Northern Ireland occurrence, on 10 December 2025. Due to the similarity with zebra mussels, DNA sequencing was used to verify identity. Departmental officials are scoping an environment DNA (eDNA) surveillance programme of larger waterbodies in Northern Ireland to monitor for the presence of quagga mussels. As with most aquatic invasive species, there is no effective control or eradication method for quagga mussels once they are present in a waterbody. Departmental efforts focus on encouraging better aquatic biosecurity by water users through the long-running Check, Clean, Dry campaign, which highlights the need to clean boat hulls and equipment in contact with water. A focused cross-border Check, Clean, Dry signage campaign, funded through the Shared Island biosecurity and invasive species initiative, is being developed to raise awareness of the ease of spread of all aquatic invasive species through poor biosecurity.
