Invasive Sea Squirt May Be in Strangford Lough

15th September 2012
Invasive Sea Squirt May Be in Strangford Lough

#MARINE WILDLIFE - The Northern Ireland Environmental Agency (NIEA) has indicated the possible presence of Japanese sea squirt on the bed of Strangford Lough, as the Press Associaton reports.

Experts are attemping to confirm the identity of the invasive organism that has posed a threat to mussel and scallop populations across the Irish Sea in north Wales.

The sea creature, Didemnum vexillum, spreads like a blanket across the seabed and other surfaces, smothering shellfish and other marine life in the process. It is often transported over large distances on boat hulls and fishing equipment.

It was discovered late last year in Holyhead marina, and Welsh athorities spent £250,000 on an extermination project to prevent its spread into the Menai Strait - at the heart of the region's shellfish industry.

Dr Rohan Holt, a senior scientist from the Countryside Council for Wales, has now been called in to advise on how to manage the threat should it indeed be confirmed as the Japanese sea quirt.

Meanwhile, members of the public have been urged to report any possible sightings of Japanese sea squirt with photos through the 'Alien Watch' section of the Invasive Species Ireland website.

We've got a favour to ask

More people are reading Afloat.ie than ever thanks to the power of the internet but we're in stormy seas because advertising revenues across the media are falling fast. Unlike many news sites, we haven’t put up a paywall because we want to keep our marine journalism open.

Afloat.ie is Ireland's only full–time marine journalism team and it takes time, money and hard work to produce our content.

So you can see why we need to ask for your help.

If everyone chipped in, we can enhance our coverage and our future would be more secure. You can help us through a small donation. Thank you.

Marine Wildlife Around Ireland One of the greatest memories of any day spent boating around the Irish coast is an encounter with marine wildlife.  It's a thrill for young and old to witness seabirds, seals, dolphins and whales right there in their own habitat. As boaters fortunate enough to have experienced it will testify even spotting a distant dorsal fin can be the highlight of any day afloat.  Was that a porpoise? Was it a whale? No matter how brief the glimpse it's a privilege to share the seas with Irish marine wildlife.

Thanks to the location of our beautiful little island, perched in the North Atlantic Ocean there appears to be no shortage of marine life to observe.

From whales to dolphins, seals, sharks and other ocean animals this page documents the most interesting accounts of marine wildlife around our shores. We're keen to receive your observations, your photos, links and youtube clips.

Boaters have a unique perspective and all those who go afloat, from inshore kayaking to offshore yacht racing that what they encounter can be of real value to specialist organisations such as the Irish Whale and Dolphin Group (IWDG) who compile a list of sightings and strandings. The IWDG knowledge base has increased over the past 21 years thanks in part at least to the observations of sailors, anglers, kayakers and boaters.

Thanks to the IWDG work we now know we share the seas with dozens of species who also call Ireland home. Here's the current list: Atlantic white-sided dolphin, beluga whale, blue whale, bottlenose dolphin, common dolphin, Cuvier's beaked whale, false killer whale, fin whale, Gervais' beaked whale, harbour porpoise, humpback whale, killer whale, minke whale, northern bottlenose whale, northern right whale, pilot whale, pygmy sperm whale, Risso's dolphin, sei whale, Sowerby's beaked whale, sperm whale, striped dolphin, True's beaked whale and white-beaked dolphin.

But as impressive as the species list is the IWDG believe there are still gaps in our knowledge. Next time you are out on the ocean waves keep a sharp look out!
