A unique whale-shaped mosaic which is set for permanent public display aims to connect present-day Wexford with its storied maritime past, as RTÉ News reports.

With the help of artist Helen McLean, Wexford Arts Centre has been creating the patterned artwork from shards of Staffordshire pottery — known as ‘chanies’ — collected from the shore at Rosslare over many decades by local woman Ann Borg.

Many of these shards are believed to originate from the wreck of a US-bound ship that went down in Moran’s Bay in the 1850s.

They have now been used to create an impression of the blue whale that famously beached in Wexford in the 1890s — the skeleton of which now hangs inside the entrance of London’s Natural History Museum.

#BlueWhale - The skeleton of a blue whale beached in Ireland that's to be the centrepiece of London's Natural History Museum has been held together by old newspapers for more than 80 years, it has emerged.

Afloat.ie previously noted the Irish origins of the giant marine mammal remains that were recovered from the Wexford coast 125 years ago – and is next year set to replace Dippy the diplodocus in the London museum's atrium.

But as Kent Online reports, it was only recently discovered that parts of the massive skeleton were being held together with copies of the Kent Messenger newspaper from the 1930s.

Staff responsible for the careful reconstruction of the blue whale specimen found dated newsprint within the plaster-like material that had been used as 'stuffing' to pack out and hold together its bones.

According to a museum spokesperson, it indicates strong connections between the English county and the workers in London who prepared the whale for display.

Voyages out as far as the edge of the Continental Shelf on the Atlantic Ocean has produced rare sightings for the Irish Whale and Dolphin Group and this August there is a chance to see the join the crew and see the whales again writes Patrick Lyne

Back in 2012 when the Celtic Mist became available to the Irish Whale and Dolphin Group we were looking at ways the boat could be used to support the work the Group does and demonstrate to people in Ireland the wealth of life that exists in Irish waters. So for three years from 2012 to 2014 we took the Celtic Mist to the shelf edge in early September. Indeed we were blessed when first arriving on the shelf edge only to be greeted by two blue whales. It took several minutes in close proximity (200m) to the whales before we believed our eyes. We had expected large whales but not those to be waiting for us. They stayed around and passed either side of the boat moving from port to starboard for what seemed like an age, before moving further away. We could manage a top speed of maybe 8 knots while blue whales could travel at up to 25 knots approximately and there was no way we could keep pace with these animals if they decided to leave us behind.

Shortly afterwards the Irish Air Corps Casa (C253) appeared and called on the radio and managed to get some excellent shots of both the Celtic Mist and the blue whales.

In 2013 had some remarkable sightings of beaked whales again in the Porcupine Seabight and while unable to confirm that the animals that passed close to the vessel in 2013, were True’s beaked whales, it seems highly probable that they were. Beaked whales are particularly difficult to study being adverse to noise and spending large periods of time underwater. The Cuvier’s beaked whale holds the record for the longest recorded dive of any cetacean of 2 hours 17 minutes while attaining a depth of 2,992m. These animals are rarely seen close to shore and when they are, they often end up stranding and dying. The deep ocean off the shelf edge is their natural habitat.

Each year has produced it’s own spectcular moments and the humpback whales off Dingle have become more and more reliable and are a feature of our trips every year. Last year we were treated to one beautiful day on the shelf edge with calm weather. It is this calm weather that always produces the best results. While whales numbers wer not spectacular they were considerable and most if not all animals were engaged in feeding. We simply allowed the boat to drift while fin whales fed in close proimity to the boat and we could see the huge jaws opening to envelope the krill underwater.

Last year we changed vessels to Jessy of Adrigole a 37 ft–yacht, the Celtic Mist being unavailable and this year we have decided to continue using Jessy but for a longer trip. We propose starting in Castletownbere and sailing to Camaret in Brittany along the shelf edge. The shelf edge between here and Brittany is some of the most dramatic in the world with drop offs from 200m down to nearly 4000m. The EEZ of the UK is slowly squeezed such that French and Irish waters will eventually meet as boundaries extend.

It is more important than ever to record the variety and abundance of Ireland’s offshore environment. While oil exploration will suffer from the current over supply, exploration rights has been granted to both Russia and France by the International Seabed Authority (ISA – not the Irish Sailing Association but a UN body based in Jamaica) in the mid-Atlantic Ridge in the North Atlantic. The marine environment is constantly under greater and greater pressure. Protection for cetaceans is critical to mainting the entire marine habitat. Reduction in large whale numbers in the Southern Ocean due to whaling did not result in an increase in their favourite prey, krill, but rather reduced krill abundance. Whale faeces enriches the ocean with iron, producing plankton blooms which start the food chain and absorb excess carbon from the atmosphere. The South West in particualr sees large numbers of tuna arrive in August and September, follwoed by French and Spanish and Irish fishing vessel as well as whales. It is important for the whales that they are able to build blubber reserves at this time, especially for the females as without sufficient reserves to sustain them during pregnancy of 11 or 12 months, the whale will abort. Recovery rates are slow with these large whales and even with protection it will be manay many decades before fin and blue whale numbers reach pre-whaling levels.

In August we will embark again to try and find calm weather on the shelf edge and hope to add significantly to the picture of cetaceans in Irish waters in a time when they are at their most abundant. It is a unique opportunity for people to become involved with our marine mega fauna in a way not available elsewhere and to add to knowledge of the area. The charge to crew of €1310 allows the work to take place and is an enriching experience and an education. If interested contact Patrick Lyne by email ([email protected]).

#MarineWildlife - News emerged this week that Dippy, the famous diplodocus cast at the entrance of London's Natural History Museum, is to be replaced with the skeleton of a blue whale.

But amid all the hubbub that this move has sparked, perhaps little known is the replacement creature's Irish origin.

According to Geographical, the magazine of the Royal Geographic Society, the museum's blue whale skeleton is from a female whale that was beached off Wexford more than 100 years ago.

The giant marine mammal was reportedly already injured when it washed up at Wexford Harbour in 1891, says whaling expert Phillip Hoare, who notes that the museum paid £250 (some £27,000 in today's money) for the carcass – which produced an incredible 630 gallons of valuable whale oil.

That rendering was done at the museum itself, which had a 'whale pit' reserved for such purposes till the 1940s, when complaints from the neighbours about the smell put paid to that practice.

What's more, the Wexford whale that will have pride of place in the museum's atrium is just one of countless other specimens acquired over the decades, many of which are stores in a warehouse in south London.

#MARINE WILDLIFE - Members of the Irish Whale and Dolphin Group (IWDG) encountered the world's largest animals off the southwest coast of Ireland last Thursday.

Two blue whales were witnessed by the team on board the Celtic Mist near the edge of the continental shelf on the Porcupine Blight, west of Dursey Island in Co Kerry.

The marine giants - last recorded in Irish waters back in 2008 - reportedly surfaced within 500 metres of the boat.

Mission co-ordinator Patrick Lyne told The Irish Times that there may even have been three whales in the pod, as three blows of seawater were witnessed in a short space of time.

He also noted that the sighting was very significant as there are estimated to be fewer than 4,000 blue whales in the entire northern hemisphere - their numbers reduced drastically by whaling over the past hundred years.

At an average of 30 metres in lengh and an incredible 180 metric tins in weight, the blue whale is the largest animal to have ever lived on earth.

The Celtic Mist was on its maiden voyage as a research vessel for the IWDG, following its gifting to the group for marine wildlife conservation work by the Haughey family last year, and subsequent major refitting works.

The vessel set sail on Monday 3 Septmeber on a marine mammal observation and passive acoustic monitoring week, carrying a towed hydrophone array for acoustic detections below the surface.

During the weeklong mission the team on board enountered 11 different cetacean species including harbour porpoises, common dolphins, minke whales and a humpback whale.

The infamous Celtic Mist is set to be used to track one of the most elusive marine animals in Irish waters.
The Irish Examiner reports that one of the first duties of the yacht under its new ownership by the Irish Whale and Dolphin Group (IWDG) will be to track down the blue whale, the last of which was spotted off the Irish coast in 2009.
"We’ve made two sightings of the blue whale on the shelf edge but with the Celtic Mist we will be able to go out there for a few weeks and sit there and wait for them," said the IWDG's Dr Simon Berrow.
"Hopefully we will find some more when we bring the Celtic Mist out there. They are very rare."
The blue whale is regarded as the largest animal to have ever lived on earth. They also have an average lifespan of well over 100 years.
As previously reported by Afloat.ie, Celtic Mist was gifted by the Haughey family to the IWDG earlier this year to assist in its marine conservation work.
The yacht competed in a leg of the 2011 Tall Ships Race from Waterford to Scotland before moving to its new home in Co Clare, where it will be refitted for its new life as a research vessel.

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.
