Five adult Dreissena polymotpha were found on the hull of a boat moored in Kinnego Marina, Lough Neagh, in November 2005; this is the first indication of their presence in this large lake. This finding initiated a survey to determine whether the zebra mussel was present throughout Lough Neagh. Forty-four settled juveniles on debris were found at twenty sites around the lough shore. As a result of these findings a more extensive study was undertaken in October 2006 to examine planktonic and settled stages. Veliger larvae were at densities of 0.0211 veligers per m(-3). Spat collectors showed settlement at six out of the seven sites sampled at a mean density of 523.76 juvenile zebra mussels per m(-2). No adult zebra mussels were found on natural substratum in the lough during the shoreline survey. However, 24 adult zebra mussels, 7.5 mm to 24 mm long, were found on the hull of a boat moored in Lough Neagh.
