Species | Dreissena bugensis | |
Date of the first record (?) | 2020 - 2021 References: Baars, J.R., Caplice, M.B., Flynn, O., O’Leary, K., Swanwick, H. and Minchin, D., 2022. The Ponto-Caspian quagga mussel, Dreissena rostriformis bugensis Andrusov, 1897, is established in Ireland. BioInvasions Records, 11. Comments: The quagga mussel Dreissena rostriformis bugensis was identified in a horizon scan of species likely to arrive in Ireland. We report on the first records of this dreissenid from two lakes, a reservoir and interconnecting navigable river sections on Ireland’s largest river, the Shannon, during July 2021. The abundance in Lough Ree was greater than in the larger downstream lake of Lough Derg. Specimens occurred to depths of 24 m and 32 m in each of these lakes respectively. Highest densities were in the southern region of Lough Ree attached to piles supporting floating pontoons and quay walls. |
Recipient region (?) | Country: Ireland LME: 24. Celtic-Biscay Shelf LME sub-region: Celtic seas References: Baars, J.R., Caplice, M.B., Flynn, O., O’Leary, K., Swanwick, H. and Minchin, D., 2022. The Ponto-Caspian quagga mussel, Dreissena rostriformis bugensis Andrusov, 1897, is established in Ireland. BioInvasions Records, 11. Comments: Overland spread could also facilitate the colonisation of D. rostriformis bugensis in the upper reaches of estuaries where salinities do not exceed between 1 and 5 (Spidle et al. 1994) |

Pathway / Vector (?) | Level of certainty: Possible Pathway: Vessels Vector: Ballast water Vector: Ship’s hull References: Baars, J.R., Caplice, M.B., Flynn, O., O’Leary, K., Swanwick, H. and Minchin, D., 2022. The Ponto-Caspian quagga mussel, Dreissena rostriformis bugensis Andrusov, 1897, is established in Ireland. BioInvasions Records, 11. Comments: More recently, it has been shown wet surfaces may be capable of transferring the veliger stage (Choi et al. 2013), this could result in additional vectors being involved in further spread such as angling equipment (Mueting et al. 2011) including waders (Aldridge et al. 2014). |
Habitat type (?) | Drain Lake River References: Baars, J.R., Caplice, M.B., Flynn, O., O’Leary, K., Swanwick, H. and Minchin, D., 2022.

Population status (?) | Common (Moderate level of certainty) References: Baars, J.R., Caplice, M.B., Flynn, O., O’Leary, K., Swanwick, H. and Minchin, D., 2022. The Ponto-Caspian quagga mussel, Dreissena rostriformis bugensis Andrusov, 1897, is established in Ireland. BioInvasions Records, 11. Comments: Highest densities were in the southern region of Lough Ree attached to piles supporting floating pontoons and quay walls. Here D. r. bugensis outnumbered the D. polymorpha present. It was present at lower densities downstream to Lough Derg and the Parteen Reservoir. |
