#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.

#MARINE WILDLIFE - Work on exterminating sea squirts at a marina in north Wales has begun.

The £250,000 (€301,000) project by the Countryside Council for Wales involves attaching giant bags to the subsurface structures around the marina in Holyhead, which is hoped will stop the clean flow of water to the sea squirts, causing them to suffocate and die.

Marine biologist Rohan Holt, who is managing the project, said: “If we successfully eradicate the sea squirt, we will work hard to make sure that it does not recolonise.

"This will mean careful monitoring in Holyhead marina and other marinas and popular mooring areas throughout Wales to check that it hasn’t reappeared."

The sea creature threatens shellfish by spreading like a blanket across the seabed and other surfaces.

As previously reported on Afloat.ie, colonies of the invasive Japanese sea squirt are posing a throat to mussel and scallop bed in the Menai Strait between Anglesey and the mainland.

Boats from Ireland have been blamed for carrying the invasive pest into Holyhead.

#MARINE WILDLIFE - Colonies of the invasive Japanese sea squirt are posing a threat to mussels and scallops in north Wales - and Irish boats are to blame, according to the Daily Post.
The sea creature - which threatens shellfish by spreading like a blanket across the seabed and other surfaces - has been discovered in Holyhead marina, allegedly carried in on the hulls of boats from Ireland.
And fears are growing that if the marine pest spreads to the Menai Strait, the effect on the local shellfish industry could be "disastrous".
To combat the problem once and for all, the Countryside Council for Wales will spend £250,000 of Welsh government funding on an extermination project at the marina, using plastic bags to smother the sea squirts and setting up quarantine facilities for incoming vessels.
The project is expected to be completed by the end of the year.

Forty Foot Swimming Spot on Dublin Bay

The 'Forty Foot' is a rocky outcrop located at the southern tip of Dublin Bay at Sandycove, County Dublin from which people have been swimming in the Irish Sea all year round for 300 years or more. It is popular because it is one of few spots between Dublin city and Greystones in County Wicklow that allows for swimming at all stages of the tide, subject to the sea state.

Forty Foot History

Traditionally, the bathing spot was exclusively a men's bathing spot and the gentlemen's swimming club was established to help conserve the area.

Owing to its relative isolation and gender-specific nature it became a popular spot for nudists, but in the 1970s, during the women's liberation movement, a group of female equal-rights activists plunged into the waters and now it is also open to everyone and it is in the control of Dun Laoghaire Rathdown County Council.

Many people believe that swimming in extremely cold water is healthy and good for the immune system.

Is it safe to swim at the Forty Foot?

The Forty-Foot is a great place to swim because there is always enough water to get a dip but like all sea swimming, there are always hazards you need to be aware of.   For example, a lot of people like to dive into to the pool at the Forty-foot but there are submerged rocks that can be hazardous especially at low water.  The Council have erected signs to warn people of the underwater dangers. Other hazards include slippy granite cut stone steps that can often be covered with seaweed and of course marine wildlife including jellyfish that make their presence felt in the summer months as do an inquisitive nearby Sandycove seal colony.
