Displaying items by tag: lion's mane jellyfish

Portaferry Coastguard Rescue Team on Strangfrod Lough in Northern Ireland has warned of hundreds of Lion's Mane jellyfish washed up on the shore at Cloughey on the eastern coast of the Ards Peninsula. It's a small village with a beautiful sandy beach.

The team warned that anyone finding a Lion's Mane jellyfish should be aware that the tentacles of this species retain their potent sting long after the jellyfish has died, and dead specimens should therefore never be touched under any circumstances; and that if a dog comes into contact with a Lion's Mane Jellyfish, immediate veterinary attention is advised as anaphylactic reactions are not uncommon.

This jellyfish uses its stinging tentacles to capture, pull in, and eat prey such as fish, zooplankton, sea creatures, and smaller jellyfish and the largest recorded was measured found of the coast of Massachusetts in 1865 and had a bell 7 feet diameter and tentacles around about 120 feet long.

Dun Laoghaire-Rathdown County Council has put up warning signs in the lifeguarded area of Sandycove in south Dublin after sightings of lion’s mane jellyfish in the water.

Though the notice was put in place yesterday (Thursday 13 June), it’s emerged there have been sightings of the venomous marine wildlife since mid-May.

Bathing has not been prohibited as it was with the water quality warning earlier this month.

But swimmers at Sandycove and further out in Dublin Bay are advised to proceed with caution for the time being.

As an added precaution the lifeguard warning flags are on red and will remain in place till further notice, the council says.

Lion’s mane jellyfish carry a painful and potentially lethal sting, even when washed up on the beach.

Last summer saw more than 150 lion's mane jellyfish recorded along the West Coast — amid a spate of incidents with swimmers being stung in Galway Bay.

But the East Coast was not immune, as a teenager was hospitalised after he was stung over most of his body off a Co Louth beach.

#Jellyfish - A whopping 157 lion’s mane jellyfish were recorded along the West Coast this summer, according to figures from the National Biodiversity Data Centre.

And as Galway Bay FM reports, more than a third of these sightings (61) were in the Galway area alone.

Swimmers in Galway were first put on alert in June after a number of people were hospitalised by stings from the dangerous marine animal.

Lion’s manes around the Irish coast this year are believed to be larger than usual to due warmers waters as well as an absence of their natural predators.

Meanwhile, the Irish Mirror has news of a ‘ghastly’ find on a Donegal beach in the shape of a partially eaten fish wholly visible inside a jellyfish.

The “savage” remains of what’s thought to be a moon jellyfish — and its final meal — were discovered by Belfast comedian Paddy Raff.

#Jellyfish - Ireland’s recent invasion of lion’s mane jellyfish has extended from Galway Bay to the East Coast, where a teenager was hospitalised after a nasty sting in recent days.

Herald.ie reports that 14-year-old Jack Dunne was stung over most of his body after getting entangled in the tentacles of a lion’s mane while swimming with friends off Port Beach, near Togher in Co Louth.

The teen needed “strong antihistamines and anti-inflammatory tablets” to recover from the intense pain of the jellyfish stings, which have the potential to cause death from anaphylactic shock.

Irish Water Safety chief John Leech warned that the dangerous marine species is not normally seen in the Irish Sea till autumn — and may be increased in number due to an absence of their natural predators, sunfish and turtles. Herald.ie has more on the story HERE.

Lion’s mane jellyfish currently being encountered in Irish waters are also larger than usual, according to one animal expert.

#Jellyfish - Lion’s mane jellyfish in Irish waters this summer are much larger than usual.

That’s according to zoologist Dr Tom Doyle, who spoke to The Irish Times after a recent spate of incidents that saw swimmers hospitalised by stings from the dangerous marine species in Galway Bay.

“It is not correct to say this is the first time they have been spotted on the west coast, as we had reports for the last two years, but they are particularly large and mature,” said Dr Doyle.

Lion’s mane jellyfish are more commonly seen in the Irish Sea, and reports of larger specimens similar to those off Galway and Clare have come in from North Wales and Liverpool.

Dr Doyle appealed for the public to report any sightings to the National Biodiversity Data Centre as well as the Facebook page for The Big Jellyfish Hunt.

#Dublin Bay junior sailors turned up to race yesterday on what was arguably one of the best sailing days of the season so far only to learn the first race of their September Series was scubbed due to 'jellyfish reasons'.

It's just the latest shut down of leisure pursuits in the capitals waters after Dun Laoghaire Rathdown County Council warned against bathing in 'Jelly fish infested waters' at nearby Sandycove.

As a finale to the 2014 season, racing was scheduled for six dinghy classes including the Optimist, Laser Radial and 4.7, Topper, Feva and 420 classes but not even the fact that over 100 junior sailors drawn from the four dun Laoghaire yacht clubs would be on the water rather than in it could stop yesterday's cancellation of the harbour races, such is the risk posed by the Lions mane jellyfish.

Last week Dun Laoghaire Harbour Master Simon Coate wrote to the yacht clubs and classes. ' A considerable number of Lions mane jellyfish have been sighted within the harbour. Please warn your members,' Captain Coate advised.

#Jellyfish - The Irish Mirror reported on Friday that 17 dangerous lion's mane jellyfish were removed from Sandycove Beach on south Dublin Bay.

However, that may be just the tip of the iceberg in their numbers as the giant venomous species flocks to Ireland's warming coastal waters from elsewhere in the Irish Sea.

Meanwhile, restrictions on bathing have been lifted from nearby Sandycove Harbour and Killiney Beach after elevated bacterial levels were detected in the water earlier in the week.

Dollymount Strand's temporary bathing ban has also been lifted, as have a number of advisories in North Co Dublin.

However, precautionary notices remain at three locations – Burrow in Sutton, Claremont in Howth and Loughshinny Beach between Rush and Skerries – due to poor results of samples collected from outfalls at those locations.

Michael Viney writes in The Irish Times on growing concerns over lion's mane jellyfish and other harmful species in Irish waters.
The lion's mane is among the largest jellies found in Ireland and comes with a powerful sting, enough to disrupt "the stoical bliss normal to Dublin's Forty Foot bathing cove".
"Last year, the jellyfish was even more abundant in the Irish Sea than in 2009, and sightings from ferries found them from coast to coast," says Viney, who notes their and other jellies' dangerous effects on the marine industry and ocean ecosystems.
The decline of certain plankton-feeding species such as herring due to overfishing, coupled with a rise in sea temperature, has led to a marked increase of jellyfish of many different species in our waters such as the mauve stinger, which is blamed for decimating a Co Antrim fish farm's entire salmon stock.

Dun Laoghaire Harbour Information

Dun Laoghaire Harbour is the second port for Dublin and is located on the south shore of Dublin Bay. Marine uses for this 200-year-old man-made harbour have changed over its lifetime. Originally built as a port of refuge for sailing ships entering the narrow channel at Dublin Port, the harbour has had a continuous ferry link with Wales and this was the principal activity of the harbour until the service stopped in 2015. In all this time, however, one thing has remained constant and that is the popularity for sailing and boating from the port, making it Ireland's marine leisure capital with a harbour fleet of over 1,200-1.600 pleasure craft.

  • 1817 - Construction of the East Pier to a design by John Rennie began in 1817 with Earl Whitworth Lord Lieutenant of Ireland laying the first stone.
  • 1820 - Rennie had concerns a single pier would be subject to silting, and by 1820 gained support for the construction of the West pier to begin shortly afterwards. When King George IV left Ireland from the harbour in 1820, Dunleary was renamed Kingstown, a name that was to remain in use for nearly 100 years. The harbour was named the Royal Harbour of George the Fourth which seems not to have remained for so long.

  • 1831 - Royal Irish Yacht Club founded
  • 1837 - saw the creation of Victoria Wharf, since renamed St. Michael's Wharf with the D&KR extended and a new terminus created convenient to the wharf.[8] The extended line had cut a chord across the old harbour with the landward pool so created later filled in.
  • 1838 - Royal St George Yacht Club founded
  • 1842 - By this time the largest man-made harbour in Western Europe had been completed with the construction of the East Pier lighthouse.
  • 1855 - The harbour was further enhanced by the completion of Traders Wharf in 1855 and Carlisle Pier in 1856. The mid-1850s also saw the completion of the West Pier lighthouse. The railway was connected to Bray in 1856
  • 1871 - National Yacht Club founded
  • 1884 - Dublin Bay Sailing Club founded
  • 1918 - The Mailboat, “The RMS Leinster” sailed out of Dún Laoghaire with 685 people on board. 22 were post office workers sorting the mail; 70 were crew and the vast majority of the passengers were soldiers returning to the battlefields of World War I. The ship was torpedoed by a German U-boat near the Kish lighthouse killing many of those onboard.
  • 1920 - Kingstown reverted to the name Dún Laoghaire in 1920 and in 1924 the harbour was officially renamed "Dun Laoghaire Harbour"

Dun Laoghaire Regatta

Dun Laoghaire's biennial town regatta was started in 2005 as a joint cooperation by the town's major yacht clubs. It was an immediate success and is now in its eighth edition and has become Ireland's biggest sailing event. The combined club's regatta is held in the first week of July.

  • Attracts 500 boats and more from overseas and around the country
  • Four-day championship involving 2,500 sailors with supporting family and friends
  • Economic study carried out by the Irish Marine Federation estimated the economic value of the 2009 Regatta at €2.5 million

The dates for the 2021 edition of Ireland's biggest sailing event on Dublin Bay is: 8-11 July 2021. More details here

Dun Laoghaire-Dingle Offshore Race

The biennial Dun Laoghaire to Dingle race is a 320-miles race down the East coast of Ireland, across the south coast and into Dingle harbour in County Kerry. The latest news on the Dun Laoghaire to Dingle Race can be found by clicking on the link here. The race is organised by the National Yacht Club.

The 2021 Race will start from the National Yacht Club on Wednesday 9th, June 2021.

Round Ireland Yacht Race

This is a Wicklow Sailing Club race but in 2013 the Garden County Club made an arrangement that sees see entries berthed at the RIYC in Dun Laoghaire Harbour for scrutineering prior to the biennial 704–mile race start off Wicklow harbour. Larger boats have been unable to berth in the confines of Wicklow harbour, a factor WSC believes has restricted the growth of the Round Ireland fleet. 'It means we can now encourage larger boats that have shown an interest in competing but we have been unable to cater for in Wicklow' harbour, WSC Commodore Peter Shearer told Afloat.ie here. The race also holds a pre-ace launch party at the Royal Irish Yacht Club.
