#torpedo – An investigation is under way after a 9ft–missile was fired from HMS Argyll at high security Plymouth nuclear submarine dockyard during a training drill this week. 

A Royal Navy spokesman said: "We can confirm an incident occurred onboard HMS Argyll on Wednesday, March 12, at 3.24pm, while the ship was alongside at Devonport Naval Base in Plymouth.

"During a training exercise, an inert Test Variant Torpedo (TVT) unexpectedly jettisoned onto the wharf. There was no explosion and no casualties.

A source said: "The torpedo came shooting out of the side of Argyll and flew through the air before going straight through a security fence.

"It's carried on going before hitting a storage container. If anyone was inside it they would have a had a nasty shock - the whole side of the container was stoved in.

#Torpedo - Taoiseach Enda Kenny had paid tribute to the Castlebar-born inventor of the steerable torpedo at the unveiling of a headstone on Louis Brennan's grave in London.

As the Irish Independent reports, Brennan - who lived from 1852 to 1932 - was a renowned inventor, credited with developing the world's first practical guided missile that he patented as the 'Brennan Torpedo', and tested at Fort Camden in Cork Harbour in the late 1870s.

Raised in Melbourne, Australia, Brennan spent much of his working life in Britain inventing for the military, developing such concepts as a revolutionary monorail system that attracted the attention of Winston Churchill.

However, following his death in a car accident in Switzerland, Brennan lay in an unmarked grave in Kensal Green, northwest London.

Now a group of history buffs from Brennan's Mayo birthplace have finally marked that spot with a headstone, as well as a plaque commemorating his life and achievements in the cemetery's oratory.

"I am pleased today that we have this opportunity to restore and publicly acknowledge the resting place of Louis Brennan," said the Taoiseach at the unveiling ceremony yesterday (11 March).

"But also, in a sense, to redeem ourselves in that we left him here alone unknown for so long."

#INLAND WATERWAYS - As Derek Evans writes in The Irish Times, the recent discovery of the first Guinness merchant vessel - sunk a century ago by a German torpedo in the Irish Sea - rekindled memories of the brewery's boats on the Liffey in the 1950s.

He writes: "Living close to Stoneybatter, I often took time to stand on Queen Street Bridge as the barges, filled with Guinness barrels, slowly made their way from James’s Gate to Sir John Rogerson’s Quay.

"I remember clearly the skipper standing beside the open wheelhouse in his navy blue polo-neck jumper, captain’s hat and pipe... The skipper always had a smile and a wave before he would disappear for a few moments under the white cloud."

He also recalls the hoisting of the barrells at Butt Bridge onto the Guinness cargo vessels - like the WM Barkley, the Lady Grania or Gwendolen Guinness - for transport to Liverpool.

As previously reported on Afloat.ie, the wreck of the WM Barkley was captured in high-resolution images taken from the national research vessel RV Celtic Voyager off the coast of Dublin.

High Resolution images of a merchant ship which was sunk ninety-four years ago today (October 12th) off the coast of Dublin have been revealed by the INFOMAR (Integrated Mapping For the Sustainable Development of Ireland's Marine Resource) Programme during a mission on the national research vessel the RV Celtic Voyager earlier this year which surveyed the wreck of the first Guinness merchant vessel, the W.M. Barkley.

The detailed seabed images, which include deck features and complex sand wave structures, were recorded by towed sidescan sonar provided by the Moore Marine Group, and give a visual insight into the defensively armed ship that was sunk by a German torpedo in 1917, seven miles east of the Kish Bank off Dublin.

Photos above and below show topographic seafloor images in 3D, showing the partially buried wreck of the W M Barkley lying at a water depth of 56 metres; with deeper scouring around it down to 72 metres (darker colours indicate greater depths). The images were created from sonar data acquired onboard the Marine Institute's research vessel RV Celtic Voyager, during INFOMAR Programme mapping in 2010 and 2011 with data processed by INFOMAR's Fabio Sacchetti (University of Ulster) and Charise McKeon (Geological Survey of Ireland).

In May 2010, during a large scale mapping survey in the Irish Sea by INFOMAR, a national marine study run by the Marine Institute and the Geological Survey of Ireland, identified a seabed feature which, to the trained eye, was discernable as a potential shipwreck lying in the same position recorded on the Admiralty Chart, the EU wreck site and UK Hydrographic Office wreck site directories, as well as a survey conducted in the 1980s as the last known position of the W.M.Barkley.

Viewing the spectacular imagery of the shipwreck Minister for Communications, Energy & Natural Resources, Pat Rabbitte, said "I am delighted to note the continued excellence of the valuable work being carried out under the INFOMAR project. These images from the deep reveal a unique view of part of Ireland's marine heritage and I am delighted to announce details of INFOMAR''s annual seminar to be held in Galway on November 16 and 17th."

Ninety four years ago on the dark night of October 12th 1917 the W.M.Barkley was torpedoed without warning by the German submarine UC-75. Within minutes the ship, which was owned and operated by the Guinness Company of Dublin, broke in two and sank, taking with her to the bottom four men including her Captain and leaving the rest of her crew to face the sea in an open lifeboat. Now, the darkness where the ship has lain in pieces has been disturbed, probed by fingers of sound that are mapping the seabed in incredible details and bringing to light the position of this famous Irish shipwreck.

"As the first Guinness owned ship, the W.M. Barkley played an important role in the story of the transportation of GUINNESS beer overseas," said Eibhlin Roche, Guinness Archivist. The events of the night of 12th October 1917 are very much part of the history of Guinness that is recorded in the Guinness Archive. It is exciting to finally know the exact resting place of the W.M. Barkley."

A scale model of the W.M. Barkley is on display in the Transport Gallery of Guinness Storehouse remembering the lives of the Guinness men who both perished and survived the events of 12th October 1917. These are stories of tragedy and bravery portraying Irish traditional values, and how they were brought to light with the application of cutting-edge technology.

Scuba Divers have found a fully intact World War I U-Boat on the seabed just outside Cork harbour, some 93 years after it sank writes Timmy Carey.

During the First World War the menace provided by German U-Boats would prove deadly to the Allies and were responsible for sinking millions of tons of shipping; indeed German U-Boats almost changed the course of the war. Most allied ships sunk by U-boats were sunk by either torpedo, deck gunfire or explosives placed aboard the ship by U-boat crew. A smaller number of ships were also sunk by mine laying U-boats; one of these being UC42. On the 10th of September of 1917 UC42 was laying her deadly cargo of mines at the entrance to Cork harbour when a terrific explosion occurred which resulted in a grim death for all 27 German Submariners aboard.

As the submarine sank to the seabed the German submariners were trapped inside UC42, which would soon become their metal tomb.

On November  2nd of that year, hardhat divers from the Haulbowline dockyard dived the area and positively identified the U-boat as UC42, noting the stern damage to the submarine and the presence of the bodies of some of the German submariners. During 1918 the submarine was dived by Haulbowline and American divers in an effort to disarm all the mines and torpedoes still aboard, with USS Melville taking three of the mines. It was widely believed that in July 1919 divers using explosives from HMS Vernon torpedo school had destroyed the submarine with the remains being dispersed on the seabed by wire sweeps.

With the advent of scuba diving many divers have since searched for the scattered remains of UC42 around Cork harbour with no luck until a recent dive by two local divers Ian Kelleher and Niall O Regan descended a shot line to see the menacing sight of the hull of a German U-boat emerge from the shadows. Both divers were very surprised and ecstatic to find a fully intact World War I U-Boat in 27 meters of water just outside Cork harbour in good condition with little obvious explosive damage from the British naval dive team.

A local dive team of five divers had spent the previous 12 months carrying out a careful methodical search of the greater harbour area determined to find the remains of the submarine; their hard labours finally paying dividends when Niall and Ian identified the presence of the submarine. The dive team consisted of Ian Kelleher, Niall O Regan, Philip Johnston,  Eoin Mc Garry and Timmy Carey.

Over the past few weeks the divers have carefully and methodically videoed and photographed the Submarine and taken various measurements to record the wrecks' condition. Over a number of dives the dive team carefully cleaned the growth from the propeller and after some methodical cleaning found the U-Boats number UC42 stamped into it; positively identifying the submarine.

As the submarine is a war grave and contains the remains of so many young German submariners the dive team also laid a plaque of remembrance, which was erected near the submarines propellers; to act as a memorial to the German submariners forever entombed in UC42. The plaque was kindly donated to the dive team by John O' Mahony of Complete Signs.

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.
