Zebra Mussels

Question: To ask the Secretary of State for Northern Ireland pursuant to the answer of 24 October 2006, Official Report, column 1787W, on zebra mussels, what steps he is taking to halt the spread of zebra mussels in the Lough Neagh.

Answer: Since zebra mussels were first found on the hull of a boat in Kinnegoe Marina on 21 November 2005 further investigation has shown that very young zebra mussels are present at several points around the Lough. This means that there is an established adult breeding population. Previous experience suggests that it is not possible to eradicate zebra mussels or halt their future spread, once they have become established. In very specific situations such as on boat hulls, jetties or pipe work it may be possible to prevent them settling and/or remove them using a variety of techniques.The Inter-Departmental Zebra Mussel Control Group will continue to work closely with the Lough Neagh Advisory Committee in relation to monitoring the spread of mussels, advising on mitigation measures and keeping the public aware of the issues.
