Experts have been puzzled by reports of strange tidal activity on the South Coast at the weekend, as TheJournal.ie reports.

On Saturday afternoon (18 June), Union Hall in West Cork saw levels in its harbours drop by as much as 70cm in a mere five minutes, before the waters flooded back — and similar incidents were reported in Wexford and across the Irish Sea in Pembrokeshire.

The bizarre situation has baffled experts, with some suggesting it could be linked to earthquakes off the Azores.

But one oceanographer believes it could be the result of an extremely rare conflation of separate atmospheric events.

Gerard McCarthy told CorkBeo that the surprise tidal moves may be the effect of a meteotsunami — a large wave caused by stormy conditions at sea — combined with the natural sloshing action, or seiching, of the waters at Union Hall.

Calls have been made for greater public awareness over the risks of incoming tides after three people were rescued off Sandymount earlier this week.

A multi-agency response involving Dun Laoghaire RNLI and the Irish Coast Guard’s Dublin-based helicopter Rescue 116 led to the casualties’ successful retrieval after they became stranded on a sandbank on Tuesday (26 April).

Speaking to Independent.ie, a local councillor called for a major advertising campaign to highlight the dangers of tides at Sandymount, which has become notorious for such incidents.

“This happens far too often and the Coast Guard use a huge amount of resources every year to rescue people who find themselves in this situation,” Fine Gael’s Cllr James Geoghegan said. Independent.ie has more on the story HERE.

The news comes in the same week as a joint appeal from the coastguard, RNLI and Water Safety Ireland to take care when on or near the water this May Bank Holiday weekend, as reported earlier on Afloat.ie.

A dog and his walker were rescued after they got cut off by the tide at Sandymount this afternoon (Thursday 4 February).

Dun Laoghaire RNLI’s inshore lifeboat assisted with recovering the duo from the water and bringing them to safety at Poolbeg beach.

National Ambulance Service paramedics arrived to give the owner a medical check-up.

At the same time, an Irish Coast Guard member and a paramedic gave Hugo the dog some TLC after his dramatic experience, as Hugo can’t swim.

Dun Laoghaire’s coastguard unit reminds the public if you see anyone in difficulty in or near the water, dial 112/999 immediately and ask for the coastguard.

The “power and mystery” of the Earth’s tides is the theme of a new three-part television series involving TG4 and several broadcasters, with Chinese backing writes Lorna Siggins.

Marine Institute scientist MacDara Ó Cuaig is presenting the Irish language version of the series, entitled Taoide, which was filmed across four continents.

The project, involving Chinese production company LIC, was funded by broadcasters TG4, BBC ALBA, BBC Northern Ireland and S4C, and the distribution company Sky Vision.

The consortium describes the three-part series as a “visually stunning exploration” of one of the globe’s most powerful natural forces.

To mark the fact that this year is the International Year of Indigenous Languages, each participating country in the co-production has received its own “bespoke” edit of the documentaries in its own indigenous language.

Television producer/director Donncha Mac Con Iomaire teamed up with Welsh company Cwmni Da to produce the Irish language version for TG4, which Mr Ó Cuaig is presenting.

TG4 says that the collaboration has already inspired the setting up of a new “Celtic Development Fund” to develop similar co-productions.

This series is being distributed in Greater China, Hong Kong, Macau and Taiwan by LIC.

Sky Vision is currently negotiating its sale to other broadcasters worldwide.

Each partner put in around £100,000, according to Cwmni Da managing director Dylan Huws in Wales.

“This means they’re getting a high-end documentary series which has been filmed all over the world,” he said.

“TG4 is delighted to join forces with our broadcasting partners in the other Celtic nations to commission an Irish language version of this ambitious series,” TG4 commissioning editor Proinsias Ní Ghráinne said, adding that the theme has a “particular resonance” for this island.

The first episode of Taoide will be broadcast on TG4 on Wednesday, May 1st, at 9.30pm, with two further episodes on May 8th and 15th.

#Coastguard - Dun Laoghaire Coast Guard was alerted at 10am yesterday morning (Wednesday 16 May) to respond to a woman and her dog who were cut off by the tide on Merrion Strand, near the seaward side of the Dublin incinerator area.

Dublin Coast Guard’s Marine Rescue Coordination Centre (MRCC) activated a procedure with consent to ping the location of the casualty’s phone to give co-ordinates to the responding emergency services.

Dun Laoghaire RNLI and the Dublin-based Irish Coast Guard helicopter Rescue 116 responded to the area and were directed in by the Dun Laoghaire coastguard team.

Rescue 116 proceeded to land on the sand bank while Dun Laoghaire RNLI’s inshore lifeboat stood by to assist. A Dublin Fire Brigade RIB from Dublin Port also responded.

The casualty and her dog were airlifted from the sand bank to awaiting coastguard personal on the beach. After checks by Dublin Fire Brigade paramedics, they were taken back from the beach to land.

Dun Laoghaire Coast Guard noted yesterday’s “very fast” spring tide which caught this dog walker unawares. Tide times for Dublin can be found online HERE.

#Tides - Irish Sailing has published the latest tide times for 2018 and 2019 for mariners in Dublin Bay (North Wall), Galway, Belfast and Cork Harbour (Cobh).

All times and related tidal variations (adjusted for Irish Summer Time) are estimates and none are verified by any national hydrographic office, so are to be referred to as a guideline only.

As the UK Bank holiday approaches the UK coastguard has issed a warning to check tides and stay safe. With the school holidays well underway and the busy bank holiday weekend around the corner, coastguards and the Shipping Minister are coming together to remind families, children and visitors of the importance of checking weather and tide times to stay safe whilst at the beach and along the coast.

Already this summer coastguards have dealt with many beach-related incidents, with a particularly high number of people being caught out by the tide and needing to be rescued after becoming stranded.  Since 1st July, almost 150 such rescues have been carried out around the UK coast, with around 80% involving children.

This latest advice is part of an ongoing programme by the Maritime and Coastguard Agency to remind those who visit our coast to have a great time and remain safe. So before you go check out the weather, sea conditions and the tide times (you can find this information on the web or many beaches display it at their entrance).  That way you can enjoy the sea safely.

In addition to checking the tide times, remember that inflatable boats and toys can be great fun, but they are more suitable for use in swimming pools than at the beach.  If you do use one at the beach, make sure that it is tethered to an adult who is in the sea with you and never use it if there is an offshore wind.  Inflatable boats and toys can easily be blown off shore, then overturn. If you are blown out to sea on an inflatable boat or toy wave your arms in the air and shout for help. If you are out of your depth, don't attempt to swim back to shore.

Be careful around cliffs and rocks – they can be slippery and crumbly. Don't climb them unless you are properly kitted out. And don't attempt to rescue people or dogs from cliffs – call 999 and ask for the coastguard.

Coastguards are also encouraging parents, grandparents and other adults to ensure that children are properly supervised on the coast. We deal with numerous cases of lost children every year and it can be very distressing for children and adults alike. Some beaches provide beach band schemes which help to re-unite children with their families if they become separated, so take advantage of these schemes if appropriate.

Try to go to a lifeguarded beach if you can and stay within the flagged area.

If you notice that someone is in difficulty, either alert the lifeguard if one is available or call the Coastguard on 999.

Shipping Minister Mike Penning said:

"As an island nation, enjoying a seaside holiday is a great British tradition.  The UK has some of the finest coastline in the world, and I want everyone to be able to enjoy it safely.  Already this year we have seen how something as simple as familiarising yourself with the tide times before you set out can make all the difference.  That is why I am encouraging anyone thinking of heading for the coast to take a few sensible precautions so they return home safely and with fond memories of a great day out.    I would also like to pay tribute to our coastguard staff and volunteers who do such a great job to keep those who use our coastline as safe as possible."

Irish Water Safety is today warning the public of the increased risk to people becoming stranded whilst walking or picking shellfish on our beaches over the weekend.

The moon will be at its closest to earth since 1993 on Saturday March 19th.
This "Lunar Perigee", or 'Super Moon' as some astrologers refer to it as, is the opposite of the "Lunar Apogee", when the Moon is furthest from Earth. Generally, the Moon looks about 12-14% larger at its perigee compared to its apogee.

This has the effect of causing very high and low tides, or increasing the range of the tide. This will expose large areas of beach and rocks which we normally don't see. Many people enjoy walking on our beaches and exploring these new areas of beach and in particular people enjoy picking shellfish to eat which become exposed during these very low tides.

The risk to the public will be of becoming stranded as the tide advances back in which can leave people in a position where they are cut off from the shore. Members of the public are cautioned to be aware of this risk and carry your mobile phone. Should you get in to trouble then call 112 or 999 and ask for Marine Rescue, giving your exact location and in particular if you are near to any conspicuous landmarks nearby to assist the Rescue Services in locating your whereabouts.

All seafarers, surfers, swimmers and divers should be aware of the increased tidal streams that will be running around our coast over the weekend; people could find themselves in peril as a result of these strong and fast tidal conditions which have not been experienced for some time now.

At 5.30 pm last night Liverpool Coastguard were alerted to a local 15 year old girl in difficulty by the Leasowe Lighthouse on Moreton Common, Wirral, on Merseyside on the far side of the Irish Sea . She was completely cut off by the tide about 100 metres out on the nearby sandbank.

The Hoylake Coastguard Rescue Team were alerted as was the RNLI New Brighton hovercraft and West Kirby inshore lifeboat.

In the meantime the local Coastguard Sector Manager Steve Travis along with his team deployed their mud sled and recovered the girl to dry land.

By 6.30 pm this evening the girl was safely back at home with her mum.

Paul Kirby, Duty Watch Manager at Liverpool Coastguard said

"Our thanks are due to Steve and his team and the RNLI crews from Hoylake and West Kirby for responding so promptly to our call.

As the evenings are now darker after the clocks went back, swift tides and sandbanks can present a major problem for the unwary in the darkness. Please take care when going anywhere near tidal waters and make sure you know the times of the tides."

Aquaculture Information

Aquaculture is the farming of animals in the water and has been practised for centuries, with the monks farming fish in the middle ages. More recently the technology has progressed and the aquaculture sector is now producing in the region of 50 thousand tonnes annually and provides a valuable food product as well as much needed employment in many rural areas of Ireland.

A typical fish farm involves keeping fish in pens in the water column, caring for them and supplying them with food so they grow to market size. Or for shellfish, containing them in a specialised unit and allowing them to feed on natural plants and materials in the water column until they reach harvestable size. While farming fish has a lower carbon and water footprint to those of land animals, and a very efficient food fed to weight gain ratio compared to beef, pork or chicken, farming does require protein food sources and produces organic waste which is released into the surrounding waters. Finding sustainable food sources, and reducing the environmental impacts are key challenges facing the sector as it continues to grow.

Salmon is the most popular fish bought by Irish families. In Ireland, most of our salmon is farmed, and along with mussels and oysters, are the main farmed species in the country.

Aquaculture in Ireland

  • Fish and shellfish are farmed in 14 Irish coastal counties.
  • Irish SMEs and families grow salmon, oysters, mussels and other seafood
  • The sector is worth €150m at the farm gate – 80% in export earnings.
  • The industry sustains 1,833 direct jobs in remote rural areas – 80% in the west of Ireland
  • Every full-time job in aquaculture creates 2.27 other jobs locally (Teagasc 2015)
  • Ireland’s marine farms occupy 0.0004% of Ireland’s 17,500Km2 inshore area.
  • 83% of people in coastal areas support the development of fish farming
  • Aquaculture is a strong, sustainable and popular strategic asset for development and job creation (Foodwise 2025, National Strategic Plan, Seafood
  • Operational Programme 2020, FAO, European Commission, European Investment Bank, Harvesting Our Ocean Wealth, Silicon Republic, CEDRA)
    Ireland has led the world in organically certified farmed fish for over 30 years
  • Fish farm workers include people who have spent over two decades in the business to school-leavers intent on becoming third-generation farmers on their family sites.

Irish Aquaculture FAQs

Aquaculture, also known as aquafarming, is the farming of aquatic organisms such as fish, crustaceans, molluscs and aquatic plants, and involves cultivating freshwater and saltwater populations under controlled conditions- in contrast to commercial fishing, which is the harvesting of wild fish. Mariculture refers to aquaculture practiced in marine environments and in underwater habitats. Particular kinds of aquaculture include fish farming, shrimp farming, oyster farming, mariculture, algaculture (such as seaweed farming), and the cultivation of ornamental fish. Particular methods include aquaponics and integrated multi-trophic aquaculture, both of which integrate fish farming and plant farming.

About 580 aquatic species are currently farmed all over the world, according to the UN Food and Agriculture Organisation (FAO), which says it is "practised by both some of the poorest farmers in developing countries and by multinational companies".

Increasing global demand for protein through seafood is driving increasing demand for aquaculture, particularly given the pressures on certain commercially caught wild stocks of fish. The FAO says that "eating fish is part of the cultural tradition of many people and in terms of health benefits, it has an excellent nutritional profile, and "is a good source of protein, fatty acids, vitamins, minerals and essential micronutrients".

Aquaculture now accounts for 50 per cent of the world's fish consumed for food, and is the fastest-growing good sector.

China provides over 60 per cent of the world's farmed fish. In Europe, Norway and Scotland are leading producers of finfish, principally farmed salmon.

For farmed salmon, the feed conversion ratio, which is the measurement of how much feed it takes to produce the protein, is 1.1, as in one pound of feed producing one pound of protein, compared to rates of between 2.2 and 10 for beef, pork and chicken. However, scientists have also pointed out that certain farmed fish and shrimp requiring higher levels of protein and calories in feed compared to chickens, pigs, and cattle.

Tilapia farming which originated in the Middle East and Africa has now become the most profitable business in most countries. Tilapia has become the second most popular seafood after crab, due to which its farming is flourishing. It has entered the list of best selling species like shrimp and salmon.

There are 278 aquaculture production units in Ireland, according to Bord Iascaigh Mhara (BIM) *, producing 38,000 tonnes of finfish and shellfish in 2019 and with a total value of €172 million

There are currently almost 2,000 people directly employed in Irish aquaculture in the Republic, according to BIM.

BIM figures for 2019 recorded farmed salmon at almost 12,000 tonnes, valued at €110 million; rock oysters reached 10,300 tonnes at a value of €44 million; rope mussels at 10,600 tonnes were valued at €7 million; seabed cultured mussels at 4,600 tonnes were valued at €7 million; "other" finfish reached 600 tonnes, valued at €2 million and "other" shellfish reached 300 tonnes, valued at €2 million

Irish aquaculture products are exported to Europe, US and Asia, with salmon exported to France, Germany, Belgium and the US. Oysters are exported to France, with developing sales to markets in Hong Kong and China. France is Ireland's largest export for mussels, while there have been increased sales in the domestic and British markets.

The value of the Irish farmed finfish sector fell by five per cent in volume and seven per cent in value in 2019, mainly due to a fall on salmon production, but this was partially offset by a seven per cent increased in farmed shellfish to a value of 60 million euro. Delays in issuing State licenses have hampered further growth of the sector, according to industry representatives.

Fish and shellfish farmers must be licensed, and must comply with regulations and inspections conducted by the Sea Fisheries Protection Authority and the Marine Institute. Food labelling is a function of the Food Safety Authority of Ireland. There is a long backlog of license approvals in the finfish sector, while the Department of Agriculture, Food and Marine says it is working to reduce the backlog in the shellfish sector.

The department says it is working through the backlog, but notes that an application for a marine finfish aquaculture licence must be accompanied by either an Environmental Impact Statement (EIS) or an Environmental Impact Assessment Report (EIAR). As of October 2020, over two-thirds of applications on hand had an EIS outstanding, it said.

The EU requires member states to have marine spatial plans by 2021, and Ireland has assigned responsibility to the Department of Housing, Planning and Local Government for the National Marine Planning Framework (NMPF). Legislation has been drawn up to underpin this, and to provide a "one stop shop" for marine planning, ranging from fish farms to offshore energy – as in Marine Planning and Development Management Bill. However, the Department of Agriculture, Food and Marine confirmed last year that it intends to retain responsibility for aquaculture and sea-fisheries related development – meaning fish and shellfish farmers won't be able to avail of the "one stop shop" for marine planning.

Fish and shellfish health is a challenge, with naturally occurring blooms, jellyfish and the risk of disease. There are also issues with a perception that the sector causes environmental problems.

The industry has been on a steep learning curve, particularly in finfish farming, since it was hailed as a new future for Irish coastal communities from the 1970s – with the State's Electricity Supply Board being an early pioneer, and tobacco company Carrolls also becoming involved for a time. Nutrient build up, which occurs when there is a high density of fish in one area, waste production and its impact on depleting oxygen in water, creating algal blooms and "dead zones", and farmers' use of antibiotics to prevent disease have all been concerns, and anglers have also been worried about the impact of escaped farmed salmon on wild fish populations. Sea lice from salmon farmers were also blamed for declines in sea trout and wild salmon in Irish estuaries and rivers.

BIM says over 95% of all salmon farmed in Ireland are certified organic. Organically grown salmon are only fed a diet of sustainable organic feed. They are also raised in more spacious pens than traditional farmed salmon. The need to site locations for fish farms further out to sea, using more robust cages for weather, has been recognised by regulatory agencies. There is a move towards land-based aquaculture in Norway to reduce impact on local ecosystems. The industry says that antibiotic use is declining, and it says that "safe and effective vaccinations have since been developed for farmed fish and are now widely used". Many countries are now adopting a more sustainable approach to removing sea lice from salmon, using feeder fish such as wrasse and lumpsucker fish. Ireland's first lumpsucker hatchery was opened in 2015.

Ireland's first lumpsucker hatchery was opened in 2015.

Yes, as it is considered to have better potential for controlling environmental impacts, but it is expensive. As of October 2020, the department was handling over 20 land-based aquaculture applications.

The Irish Farmers' Association has represented fish and shellfish farmers for many years, with its chief executive Richie Flynn, who died in 2018, tirelessly championing the sector. His successor, Teresa Morrissey, is an equally forceful advocate, having worked previously in the Marine Institute in providing regulatory advice on fish health matters, scientific research on emerging aquatic diseases and management of the National Reference Laboratory for crustacean diseases.

BIM provides training in the national vocational certificate in aquaculture at its National Fisheries College, Castletownbere, Co Cork. It also trains divers to work in the industry. The Institute of Technology Carlow has also developed a higher diploma in aqua business at its campus in Wexford, in collaboration with BIM and IFA Aquaculture, the representative association for fish and shellfish farming.
