#watersafety – Irish Water Safety is appealing to the public to take extreme care when taking part in sponsored swims. Participants can be distracted by the occasion and take chances beyond what is acceptably safe and can be left without sufficient strength to climb out of the water due to the cold. Cold winter waters can cause "cold shock" and hypothermia can set in within minutes, overwhelming the fittest of swimmers.
People organising Christmas swims should ensure that they provide comprehensive details of each event to the Irish Coast Guard and local Gardai.
Each event should have a Safety Officer appointed, who will advise those concerned on safety and have the ultimate responsibility for making decisions in relation to the swim being on or off on the day on the day dependent on weather and tidal conditions remembering that there is a new moon on the 22nd of December so there will be spring tides leading to strong tidal streams on Christmas day.
If the seas are rough and weather deteriorates, they should defer the event to a more suitable day without question and not take a chance on running the event.
Many participants will not have swum since the summer and the temperature of the water has now dropped from approximately 17°C to 10°C, therefore we advise inexperienced swimmers to wear a wetsuit.
It is a fallacy that alcohol will keep you warm when entering the water; in fact it has the reverse effect and could kill you. Irish Water Safety strongly recommends that no alcohol be taken either before the swim or after the swim and also remind people that they may be in breach of the drink driving laws when driving to or from the event.
Cold water can cause cold shock and hypothermia in minutes, because the temperature of the water at this time of year will be below 10°C. Christmas day charity swimmers occasionally remain too long in the water in a gesture of bravado and can find themselves left without sufficient strength to climb out of the water becoming unbalanced and disoriented due to them becoming hypothermic, two or three minutes is plenty of time in the water for the inexperienced. Remember shivering and teeth chattering are the first signs of Hypothermia.
Ensure that you have safe access and egress with appropriate shallow shelving or ladders as appropriate. People should be mindful that steps leading into the water might be dangerous due to the growth of algae..
Swimmers' remaining in the water for extended periods in a gesture of bravado is not acceptable. The message is "Get In, Get Out and Warm Up" and in the event of an emergency call the Coast Guard on 112.

#openseaswim – The attempt by well known open water swimmer Steve Redmond to swim from Ireland to Wales ended in the early hours of Thursday morning (22 August) on the advice of his support team, which included medical personnel, after he showed signs of hypothermia just hours into the swim. He had left Carne Pier in Wexford earlier and was bound for St. Davids in Wales.

Steve has already made history for being the first man ever to complete the gruelling Seven Oceans Swim and was looking to take on the challenge of being the first person to swim from Ireland to Wales. He was also raising funds for the RNLI.

Speaking on the decision to end the swim John Kearney from Steve's support team said, "While I know many people will be disappointed, not least Steve himself, we made the right decision to end the attempt. Our main focus and concern was always Steve's health and when he started displaying worrying signs of hypothermia we felt that with such a long swim ahead of him it was not worth the risk. Steve has swam some of the most gruelling oceans and he knows that everything has to be right and you don't take chances.

I want to thank everyone for their support for Steve and this swim. It would have been an amazing accomplishment to add his incredible collection of endurance swims."

# ROWING RESCUE: The Fisa Rowing Tour on the Shannon has been suspended a day before the scheduled finish after a number of boats were swamped during a squall on Lough Derg. Fourteen boats, which take a crew of five, were on the water at the time. All the rowers were accounted for and though some rowers were treated for hypothermia, none needed to go to hospital.

The full number on the tour, which is popular with retired people, was 101, but 31 had either taken the day off or were cycling alongside the Shannon.  

The organisers were surprised to hear reports that 18 boats were “capsized” and that rowers did not have life jackets. “All rowers were wearing lifejackets or had access to them,” one of the main support personnel said. For a time one boat was thought to be missing, but the rowers were on land.

#MCIB - The families of two fishermen found dead at sea off the Skerries last April may never uncover the circumstances that led to their demise. But the official report into the incident indicated that the absence of lifejackets was a significant contributing factor.

Ronan Browne (26) and David Gilsenan (41) were reported missing on the evening of 1 April after failing to return from a trip tending to lobster pots.

Their vessel, Lady Linda, was found the following morning upturned in an oil slick off Clogherhead with no sign of the crew.

It wasn't until a week later that their bodies were discovered caught in the vessel's fishing gear some five miles east of Clogherhead, as previously reported on Afloat.ie.

Post-mortem results found that both men died from drowning, with Gilsenan also showing signs of hypothermia.

With no eyewitnesses to the incident, the report by the Marine Casualty Investigation Board (MCIB) indicated a number of possible causes from eqiupment malfunction or shifting of lobster pots on deck, to the wave height and weather conditions on the day, which were reportedly deteriorating when the boat left port.

It also said that Browne and Gilsenan "were lifelong friends, both men were experienced and qualified marine engineers in the fishing vessel industry. Both men were experienced in boat handling and fishing and had worked together on many occasions."

But the report emphasised the lack of personal flotation devices (PFDs) on board, and noted that emergency equipment was stored under the deck and not easily accessible.

The MCIB's recommendations include a review of the code of practice for fishing vessels under 15m to establish "revised stability critera" and ensuring that all boats are fitted with automatic radio beacons that deploy upon capsize.

In a separate incident, lack of proper maintenance led to an unlicenced boat taking on water off Co Kerry last August.

The Claire Buoyant was carrying one crew, five passengers and 21 sheep from Beginish Island to Ventry when the vessel began to lose stability.

Skipper Eoin Firtear - who the MCIB described as having "limited sea-going experience" - and his five passengers were rescued by passenger ferry. All sheep were jettisoned overboard, with 18 eventually recovered.

The report reminded that the carriage of livestock should only be undertaken in appropriately certified vessels.

Four teenagers were rescued in Co Down last weekend when they were cut off by the tide, the News Letter reports.
The teens were caught up to their shoulders in water at Ardilea on Saturday evening when they were retrieved by a former volunteer coastguard who lives nearby.
The group were met at the shore by the South Down Coastguard Rescue Team and NI Ambulance Service paramedics and taken to hospital showing signs of hypothermia.
Meanwhile, on Friday night RNLI Bangor lifeboat rescued a young girl stranded on a rock near Groomsport after a call from a member of the public.
“With waves breaking around the knees of the frightened child it was paramount that she be brought ashore as quickly as possible," said a coastguard statement.
The girl was treated by waiting paramedics at the shore.

At 6.00 pm yesterday, Belfast Coastguard received a 999 call from one of a party of four teenagers who were cut off by the tide and were up to their shoulders in water close to Ardilea, while walking from Ballykinler to Dundrum.
Belfast Coastguard immediately tasked Southdown Coastguard Rescue Team and requested the launch of the Newcastle RNLI Inshore Lifeboat. Northern Ireland Ambulance Service also responded to the incident.
Whilst search and rescue units were proceeding to the incident, a gentleman who has formally served as a volunteer Coastguard and lives nearby assisted in the rescue. He managed to get his dinghy into the water and get to the teenagers who were showing signs of hypothermia and were complaining of the cold.
After recovering all four teenagers with his dinghy, he made shore to be met by members of Southdown Coastguard Rescue Team and NI Ambulance Service paramedics. The four were transported to hospital by two ambulances for further assessment.
Gary Young, Watch manager, Belfast Coastguard said:
These teenagers are extremely lucky to have been rescued this evening.  I would like to pay tribute to the quick thinking of a former Coastguard who's actions certainly made for a happy ending to this potentially life threatening incident.  Southdown CRT also showed their professionalism throughout this incident which was co-ordinated by MRCC Belfast.
We would like to remind anyone visiting the coast to take great care near water.  Do not put yourselves at risk and if you find yourselves in trouble, dial 999 and ask for the Coastguard.

The report by the Marine Casualty Investigation Board into the loss of a kayaker in Castletownshend last year has found the death was caused by hypothermia and heart failure due to a pre-existing condition.
Didier Heneault, 56, died while kayaking with his wife Margaret near Horse Island, after his kayak overturned in choppy water.
The French couple, who were experienced kayakers, had set off from the League near Raheen Town in Co Cork on the morning of 30 May 2010, paddling south east.
On the western side of Horse Island, Mrs Heneault turned and saw that her husband was in thw water about 10m from his kayak. She tried to assist him in climbing out of the water back into the kayak but was unsuccessful.
Mrs Heneault used a safety rope to keep her husband afloat, but after 10 minutes he became unresponsive.
Some hours later passing kayakers heard Mrs Heneault's calls for help and assisted in towing the couple back to shore at Horse Island, where they gave Mr Heneault CPR. They were joined shortly after by the Baltimore Inshore Lifeboat and the Toe Head coastguard unit.
Mr Heneault was transferred to a waiting ambulance at Castletownshend pier where he was treated by paramedics before being taken to Cork University Hospital. There he was pronounced dead at 4.50pm.
The report into the incident by the Marine Casualty Investigation Board (MCIB) said the post-mortem gave the cause of death as cardiac failure due to hypertensive cardiomyopathy following immersion in cold water and associated hypothermia, with a medical history of hypertension.
The report also recommended that lifejackets should be used instead of buoyancy aids when offsore kayaking, where the risk of capsizing is greater. A lifejacket of 150 Newtons or more would have kept Mr Heneault's head above water at all times, it said.

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.
