Enda Kenny

Question:

199 Mr. Kenny asked the Minister for the Marine and Natural Resources the studies, if any, his Department has carried out regarding zebra mussels incidents in lakes and waterways in Ireland arising from their discovery in Lough Derg and the lower regions of the Shannon some time ago; if his attention has been drawn to the difficulties presented by an expansion in numbers of this mussel; and the proposals, if any, he has to protect our waterways and fishing stock arising from this increased growth in numbers. [1414/98]

Enda Kenny

Question:

200 Mr. Kenny asked the Minister for the Marine and Natural Resources if he will establish a national zebra mussel research centre; the proposals, if any, he has to introduce a comprehensive monitoring programme in this regard; if he will report on the economic and ecological damage caused by zebra mussels and their growth in numbers; and if he will make a statement on the matter. [1415/98]

I propose to take Questions Nos. 199 and 200 together. I refer the Deputy to my answer to a similar question to the House on 10 December 1997 and wish to advise on the updated position. The Marine Institute's fisheries research centre is already engaged in a study of the zebra mussel. Research work is also in progress in University College Galway. The Marine Institute has, at my direction, carried out extensive surveys of the distribution of the species and will continue these studies in 1998. The zebra mussel steering group established by the Marine Institute, to which I referred in my reply on 10 December 1997, has met on a number of occasions and is at present examining the reports on the spread and impact of the species. A precautionary approach is being adopted and every effort is being made to supply all parties involved with relevant information. Two information leaflets, with my endorsement, have been revised and reprinted and widely circulated to a targeted readership, including boat owners and fishermen in particular. Furthermore, an international conference of experts will take place in Galway next month organised by University College Galway with support from the Marine Institute. Following this conference the Marine Institute will compile and publish a further leaflet giving the most up-to-date information on the impact of the species and any appropriate remedial measures. Another international meeting on the subject will take place in Dublin at the Congress of the International Limnological Association in August.

The zebra mussel has been present in the UK and Europe for about 170 years, and I am advised that there are no records of damage in the UK or continental Europe caused by this species. No serious economic damage caused by the zebra mussel has been reported in this country, nor has any ecological damage become apparent to date.
