Trial Dredging to Help Rid Barrow of Invasive Asian Clam

#INLAND WATERWAYS - Trial dredging operations to curtail the spread of Asian clams at designated sites in the lower River Barrow are set to conclude today.

Inland Fisheries Ireland (IFI) employed the use of a a traditional cockle harvesting boat to physically remove the clams from the river bed, in an effort to explore methods of controlling or eradicating what it describes as an "ecosystem-changing invader" in other infested waters.

IFI scientists supervised the trials, using teams of divers to quantify the result of the dredging efforts.

The Asian clam (Corbicula fluminea) is "a most unwelcome addition to the fauna of the lower River Barrow". The bivalve mollusc is regarded as "one of the most notorious aquatic invasive species in the world".

First recorded in the river downstream of St Mullin’s in April 2010, subsequent IFI studies have revealed that the Asian clam is firmly established in the lower Barrow and in the River Nore downstream of Inistioge. Populations have also been recorded in the River Shannon and in Lough Derg.

In one section of the River Barrow the clam has achieved a "staggering" density of almost 10,000 per square metre.

Dr Joe Caffrey, senior scientist with IFI, said of the trial dregding: “It is imperative that every effort is made to control the expansion and spread of this highly adept invasive species.

"The results from these trials will inform future national management plans for this most unwelcome non-native species and will, at the very least, dramatically reduce the numbers of individuals in the test sites.

He added: "In tandem with these trials, research effort is being focused at producing other control methods that can be targeted as this species.”

Irish Sailing

The Irish Sailing Association, also known as Irish Sailing, is the national governing body for sailing, powerboating and windsurfing in Ireland.

Founded in 1945 as the Irish Dinghy Racing Association, it became the Irish Yachting Association in 1964 and the Irish Sailing Association in 1992.

Irish Sailing is a Member National Authority (MNA) of World Sailing and a member of the Olympic Federation of Ireland.

The Association is governed by a volunteer board, elected by the member clubs. Policy Groups provide the link with members and stakeholders while advising the Board on specialist areas. There is a professional administration and performance staff, based at the headquarters in Dun Laoghaire, Co. Dublin.

Core functions include the regulation of sailing education, administering racing and selection of Irish sailors for international competition. It is the body recognised by the Olympic Federation of Ireland for nominating Irish qualified sailors to be considered for selection to represent Ireland at the Olympic Games. Irish sailors have medalled twice at the Olympics – David Wilkins and Jamie Wikinson at the 1980 games, and Annalise Murphy at the 2016 games.

The Association, through its network of clubs and centres, offers curriculum-based training in the various sailing, windsurfing and powerboating disciplines. Irish Sailing qualifications are recognised by Irish and European Authorities. Most prominent of these are the Yachtmaster and the International Certificate of Competency.

It runs the annual All-Ireland Championships (formerly the Helmsman’s Championship) for senior and junior sailors.

The Association has been led by leading lights in the sailing and business communities. These include Douglas Heard, Clayton Love Junior, John Burke and Robert Dix.

Close to 100 sailors have represented Ireland at the Olympic and Paralympic Games.

Membership of Irish Sailing is either by direct application or through membership of an affiliated organisation. The annual membership fee ranges from €75 for families, down to €20 for Seniors and Juniors.
