New predictive technology being developed in Estonia could help prevent the spread of pollution from shipwrecks.

Estonia’s public broadcaster ERR News reports on the monitoring system created by marine scientists at Tallinn University of Technology (TalTech) that may forecast where fuel will spread in the water from a hazardous wreck site.

Estonia’s coastline on the Gulf of Finland, Gulf of Riga and Baltic Sea has a large number of decades-old shipwrecks which are increasingly prone to fuel leaks as they age.

So far the results are promising, with TalTech’s predictive computer models — using current and wave data from Estonian waters — matching real-world data collected from smart buoys placed at a number of coastal sites.

Surveyors for the INFOMAR seabed mapping programme have reported the detection of two obstructions on the Atlantic floor some 30 nautical miles west of Co Galway.

Marine Institute research operations manager Aodán Fitzgerald told RTÉ News that these obstructions are likely shipwrecks.

“There are thousands of these in Irish waters,” he said. “However as these are fishing areas, we issued a notice to advise fishermen with towed fishing gear to avoid the areas.”

As previously reported on Afloat.ie, a series of seabed mapping surveys was launched in February this year, with the RV Tom Crean recruited to carry out operations west of west of Kerry, Clare and Galway outside the 30nm limit.

The State’s latest marine research vessel found one of the objects around 80km west of the Aran Islands in Galway Bay, and the other 70km west of Loop Head in Co Clare.

Coordinates for the obstructions are included in Marine Notice No 64 of 2023, attached below.

Shipwrecks with no known owner will become State property under new legislation which Minister of State for Heritage Malcolm Noonan is proposing.

The legislation also proposes that commercial salvage law does not apply to historic wrecks.

The Monuments and Archaeological Bill intends to revise and replace the National Monuments Acts 1930 to 2014.

It was presented by Noonan on Thursday evening to the Joint Committee on Housing, Local Government and Heritage.

The Department of Housing said the proposed Bill seeks to introduce new measures to protect archaeological structures and sites.

It will include the establishment of a single register of monuments, a statutory reporting scheme for newly discovered monuments and provisions to prevent the illicit import and possession of stolen cultural property.

“Another innovative element of the proposed Bill is to incorporate historic wrecks and underwater cultural archaeological objects into the new scheme for monument protection,” it said.

“The proposed Bill will also enable the State to ratify and give effect to several important international conventions relating to the protection of cultural heritage,” the department said.

Multiple amendments to the National Monuments Act 1930, along with multiple transfers of functions, have resulted in “fragmented legislation which is far from easily accessible and comprehensible”, it explained.

“The proposed legislation aims to address a range of structural issues, simplify terminology, as well as provide a single accessible piece of legislation,” the department said.

“This proposed Bill will modernise existing legislation protecting monuments and archaeology – some of this legislation dates back to the 19th century,” Noonan said.

“ If enacted, this legislation will substantially strengthen protection of archaeological heritage for the enjoyment of future generations and also represent major progress on the protection of our built heritage,” he said.

He referred to the department’s recent publication of a Vernacular Strategy to protect traditional buildings.

He said there were plans to launch “Heritage Ireland 2030” in the coming weeks, as in a “new national heritage plan to provide a vision and backdrop to realise our full set of ambitions for Ireland’s built, natural and archaeological heritage”.

The Department of Transport advises that a survey will take place at several offshore reefs and sandbanks off the North West Coast from next Friday 23 April to Tuesday 4 May.

Survey works with marine robots in support of the EU Horizon 2020 research and innovation programme will take place within a three-nautical-mile radius of six shipwrecks, the coordinates of which are included in Marine Notice No 24 of 2021 which can be downloaded below.

The survey will be conducted from the RV Celtic Explorer (callsign EIGB) which will conduct acoustic surveying during the night using its hull mounted multibeam, with remotely operated vehicle (ROV) sampling during daylight hours.

In addition, the vessel will be used as a platform to deploy a range of unmanned underwater vehicles (UUVs) and a series of six small (1.2m3) pyramidal landers, referred to as baited remote underwater video (BRUV).

At all times, the RV Celtic Explorer will display appropriate lights and signals.

Dublin Bay Old Gaffers’ Association invites all to join their next Zoom session on Shipwrecks Around Dublin Bay, which will be given by Cormac Lowth on Thursday 25th February at 20.00hrs.

Following on from his extremely popular talk on the loss of the Palme and the tragic demise of the Kingstown Lifeboat in 1895, the renowned maritime archaeologist and historian Cormac Lowth will talk on “Shipwrecks Around Dublin Bay.” Based on historical research, hydrographic surveys, underwater photography and data from his own diving expeditions, Cormac will reveal the stories behind many of the shipwrecks hidden under the waves of Dublin Bay and the nearby coast.

Only partially protected by the offshore shoals of the Bennet and Kish Banks, Dublin Bay has proved to be a graveyard for many ships. Closer inshore the Burford and Rosbeg Banks lie in wait for the unwary.

The sinking of the Queen Victoria

Cormac will describe the sinking of the Queen Victoria in 1853, the Tayleur on Lambay in 1854, the Vanguard in 1875, the Palme in 1895 and the Bolivar in 1947 to name but a few. If you are interested in Dublin Bay and marine archaeology you will not want to miss this talk.

Please be early to be sure of getting a good seat!

“Substantial progress” is being made in the recovery of gold bullion from a ship wrecked off Donegal nearly 80 years ago, as RTÉ News reports.

Atlantic Subsea Ventures is involved in the salvage operation at the Empress of Britain, a luxury ocean liner that was requisitioned for the war effort in 1939 and targeted by the Nazis the following year.

A number of such vessels are believed to lie in the depts around Ireland, with one in recent years — the SS Gairsoppa off Galway — giving up a record 48 tonnes of silver bullion seven years ago.

The Empress of Britain, which is believed to hold as much as €500 million in gold bullion, was found in 1995 but its location in deep waters precluded any salvage expedition, until now — thanks to remote-operated technology used in the oil and gas industry.

What’s proving a bigger stumbling block for the salvage company, it says, is Ireland’s 7.5% levy on recovered cargo which must also be held for a year and a day before it can be moved on.

RTÉ News has more on the story HERE.

Shipwrecks off the Irish coast are acting as artificial reefs for corals usually found much deeper in the Atlantic.

That’s according to NUI Galway ocean scientist Anthony Grehan, who told the Irish Examiner about his recent surprising find at the wreck of a cargo vessel 160 metres below the surface.

Using the new submersible robot Étáin from the University of Limerick, Grehan and a team on the RV Celtic Explorer found examples of the stony coral species lophelia pertusa, which usually found at depths of 500 metres or more.

And the new discovery suggests that such wrecks may provide the necessary stability for deep-water corals to thrive in shallower waters.

#Shipwrecks - Heritage Minister Josepha Madigan yesterday (Wednesday 25 April) announced the launch of a new website with an interactive map of the thousands of historic shipwrecks in Irish waters.

The Wreck Viewer has been developed to facilitate free and easy access to the Wreck Inventory of Ireland Database compiled by the National Monuments Service of the Department of Culture, Heritage and the Gaeltacht. 

The database holds information on over 18,000 known and likely wreck sites both off the Irish coast and in Ireland’s inland waterways

These wrecks span the entirety of maritime travel around and within the island, from prehistoric logboats to medieval trading vessels, warships and ocean liners

Detailed are exact locations for approximately 4,000 of the recorded wrecks. The map also provides summary information on individual wrecks and their history, voyage, cargo, passengers and, if known, the circumstances of their loss. 

Information on the 14,000 wrecks in the database for which locations have yet to be fully confirmed can also be downloaded. Further details of these wrecks will be added to the database as they become available.

The Wreck Viewer complements the department’s Historic Environment Viewer, which provides information on archaeological sites across the country from the Sites and Monuments Record compiled under the National Monuments Acts and from the National Inventory of Architectural Heritage.

Speaking on the new Wreck Viewer yesterday, Minister Madigan said: “Of particular interest, in this decade of centenaries, are the stories of those wrecks from the First World War. 

“Over 1,000 ships were lost off the coast of Ireland during that conflict, in effect bringing the Western Front to our shoreline and alerting the Irish people to both the grim realities of war and the scale of the tragic loss of life that took place on land and sea.”

The minister added that it’s hoped the website will “promote a much greater appreciation and awareness of our marine heritage and at the same time provide an essential tool to help the protection of this remarkable resource.”

#Archaeology - With yet another stormy weekend comes news that continued coastal erosion on the West Coast has exposed the remains of a shipwreck at Killary Harbour.

According to The Irish Times, the wreck on Tallaghbaun Strand is already known to locals though its origins are as yet unclear.

But archaeologist Michael Gibbons believes it could date from the late medieval period, as wrecks from the Spanish Armada have been identified in the region.

Gibbons has also been researching what appear to be the remains of a late Bronze Age or early Christian monastic site on Kid Island in Broadhaven Bay. The Irish Times has more on the story HERE.

#Shipwrecks - Two new shipwrecks have been discovered in Connemara in areas known to be used by smugglers in centuries past, as The Irish Times reports.

Currach fisherman John Bhaba Jeaic Ó Conghaíle found the skeletal remains of what's thought to be an 18th-century vessel at Cuan Chaisín in Ceantar na nOileáin.

Elsewhere, Fahy Bay resident Michael Barry located a second wreck, believed to date from the 19th century, near his home on the northwest Connemara coast – inshore from the Spanish Armada wreck Falco Blanco Mediano.

The area is known as the birthplace of sea captain George O'Malley, one of the most notorious smugglers of his day.

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.
