Intervals and Invaders – Zebra Mussels in the Corrib

October 24, 2007

According to Wiki – Interval = certain subset of an ordered set.

There has been a certain subset of an ordered set on the Moore Group blog. It’s been very busy and due to a number of conflicting events we were unable to attend the Great Irish Beer Festival and so can’t comment on it’s success or otherwise – perhaps someone might report on it for us?

On a more serious note the Western Regional Fisheries Board has confirmed the presence of Zebra Mussel in Lough Corrib. Zebra Mussels are native to the Aral and Caspian Sea area of Eastern Europe and were first described by the Russian Zoologist Pallas in the 18th century. Since then this little thumbnail sized mussel has managed to spread to most freshwater waterways of Europe, reaching Britain in 1824 and the Great lakes of America in the later 1980’s. Infestation of lakes in the Shannon system has already caused widespread losses in floral and faunal diversity. According to the Mayo News on 2 October – “During an investigation last week it was confirmed that zebra mussels were present in the waters of Lough Corrib. It is confined to that area at the moment but, unfortunately, once it enters a lake system it multiplies rapidly. We will try to prevent it spreading to other inland waterways and intend to work with Galway and Mayo local authorities and other interested parties,” said Mr Kevin Crowley, Western Regional Fisheries Board.

Eoghan has a piece on the Moore Marine blog on the issue and its well worth reading.
