Quagga Mussel: Invasive Species Detected in NI for First Time
The quagga mussel threatens native species and infrastructure with no current eradication method; officials urge strict biosecurity as it spreads via recreational watercraft.
- On December 15, 2025, DAERA announced the first confirmed quagga mussel in Lower Lough Erne, Co Fermanagh, after AFBI samples were verified by DNA analysis at Queen's University Belfast.
- DAERA said the arrival most likely came from a connected invasion along the Shannon–Erne corridor, as quagga mussels native to the Ponto-Caspian region have spread across Western Europe, North America and Mexico.
- Scientists note quagga mussel occupies more depths than zebra mussel, outcompeting it, and can block infrastructure like water pipes; there is no effective control once established.
- Officials are identifying other waterways to be checked while DAERA urges strict `Check, Clean, Dry` biosecurity, engaging stakeholders and calling for increased vigilance among water users.
- DAERA warned quagga mussels can spread rapidly and alter food webs, saying it is plausible they are undetected in Upper Lough Erne while cross-border work continues through the Shared Island Biosecurity and Invasive Species Initiative.
