Part of Dublin’s original sea wall dating back to the late 1720s has been discovered during excavations beneath a former electricity substation at Dublin Port.

Announcing the find today (Wednesday 5 October), Dublin Port Company also revealed the discovery of dockworker artefacts including clay pipes, leather shoe parts and pottery fragments from the 19th century.

The “historic” unearthing was made during works being carried out on the former redbrick electricity substation located near the junction of East Wall Road and Alexandra Road in the grounds of Port Centre.    

“The original sea wall once enclosed the eastern and northern sides of newly reclaimed land that would become known as the North Lotts – acting as a polder,” the port company explains.

“As the port extended eastwards away from the city, the sea wall’s original purpose became obsolete, and the facing stones of the wall were removed.

“It is likely that the stones were re-used to construct the three-metre-high boundary wall that defines the port’s perimeter today, visible from East Wall Road. It is from this original sea wall that the area known as East Wall derives its name today.”   

Jim Kelleher, head of special projects with the port’s heritage and communications team, said: “We have long suspected that part of the original sea wall may have lain beneath the old redbrick substation, which itself is a protected structure.

“But it has been incredibly exciting to have those suspicions confirmed, and to see this part of the original ‘East Wall’ for the first time.” 

The port company promises that the sea wall — visible through a glass floor — and related items will on permanent display within the restored substation at Port Centre. Dublin Port has more on the story HERE.

#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.

#Archaeology - It was quite a turn-up for the books on Omey Island recently as a US student found a 12th-century brooch in the sand on the Connemara tidal island.

As The Irish Times reports, the rare kite brooch was discovered by chance by McKenna McFadden while on a field trip with fellow New York University students led by Michael Gibbons, a local archaeologist.

It's since been identified as being 900 years old, and will be offered to the collection of the National Museum.

Omey Island is also the subject of a new book charting its remarkable history, as previously reported on Afloat.ie.

#StormRachel - Ireland needs a dedicated 'rescue unit' to protect sensitive heritage sites around the coast from severe weather, as news of damage to some vulnerable spots emerges.

Michael Gibbons, an archaeologist from Connemara, told The Irish Times that while the high winds whipped up by the likes of last week's Storm Rachel have helped uncover new archaeological finds, there is as yet no procedure for protecting such finds from further weathering and erosion.

Gibbons commented specifically on the midden deposits uncovered in Roundstone on Galway Bay, which were hit by strong gales and exposed the vulnerable dunes in the area to further destruction.

#SpanishArmada - A rudder from a ship that formed part of the Spanish Armada discovered at a beach in Co Sligo recently has been transferred to the care of the National Museum for preservation and study.

As Sligo Today reports, the 20-foot rudder was found on the beach at Streedagh – renowned for hosting the wrecks of three ships from the 1588 galleon fleet – by a local farmer, who contacted the Department of Heritage's Underwater Archaeology Unit.

Dr Nessa O'Connor of the National Museum, who was engaged to dive at the Streedagh site with Dr Douglas McElvogue of the Mary Rose Trust, was said to be so impressed with the discovery that she arranged for it to be immediately removed for preservation.

The rudder is almost completely intact, with a piece missing which the archaeologists believe may have been picked up at random by a passer by believing it to be driftwood.

It's hoped that this part can be recovered to put together "an important piece of history". Sligo Today has more on the story HERE.

#CoastalNotes - The recent discovery of a piece of worked flint at Lough Hyne on the West Cork coast could unlock the secrets of 4,000 years of settlement in the area.

Cork's Southern Star reports that the archaeological find at Ballinard on the marine lake and nature reserve is what remains of a core piece of flint "which would have been worked on, or knapped, by a skilled stone worker" to create tools such as blades and arrowheads.

It's unknown how the flint came to be in the area, as it is not a rock common to West Cork, though it is supposed that it arrived either as a result of trade with people from the Antrim area - Ireland's main source of flint - or brought ashore as 'moonstones' by fishermen off what is now Galley Head.

The Southern Star has much more on the story HERE.

#GALWAY BAY NEWS - Archaeologists in Galway Bay have unearthed an extensive tidal weir complex at Barna and a late medieval quay on Mutton Island, The Irish Times reports.

The weir, which is estimated to date from the early Christian period, consists of a granite barrier with channels cut through it, designed to control the flow of water in the adjacent lagoon.

Connemara archaeologist Michael Gibbons suggests that the weir implies a considerable fish stock migrating through the area into the Barna river.

The remains of a large Iron Age fort which overlooks the site may also have given its name to the townland of Knocknacarra, which is now a populous suburb of Galway.

Meanwhile, further east at Mutton Island a medieval quay which predates the current lighthouse quay has been found.

Irish Fishing industry 

The Irish Commercial Fishing Industry employs around 11,000 people in fishing, processing and ancillary services such as sales and marketing. The industry is worth about €1.22 billion annually to the Irish economy. Irish fisheries products are exported all over the world as far as Africa, Japan and China.

FAQs

Over 16,000 people are employed directly or indirectly around the coast, working on over 2,000 registered fishing vessels, in over 160 seafood processing businesses and in 278 aquaculture production units, according to the State's sea fisheries development body Bord Iascaigh Mhara (BIM).

All activities that are concerned with growing, catching, processing or transporting fish are part of the commercial fishing industry, the development of which is overseen by BIM. Recreational fishing, as in angling at sea or inland, is the responsibility of Inland Fisheries Ireland.

The Irish fishing industry is valued at 1.22 billion euro in gross domestic product (GDP), according to 2019 figures issued by BIM. Only 179 of Ireland's 2,000 vessels are over 18 metres in length. Where does Irish commercially caught fish come from? Irish fish and shellfish is caught or cultivated within the 200-mile exclusive economic zone (EEZ), but Irish fishing grounds are part of the common EU "blue" pond. Commercial fishing is regulated under the terms of the EU Common Fisheries Policy (CFP), initiated in 1983 and with ten-yearly reviews.

The total value of seafood landed into Irish ports was 424 million euro in 2019, according to BIM. High value landings identified in 2019 were haddock, hake, monkfish and megrim. Irish vessels also land into foreign ports, while non-Irish vessels land into Irish ports, principally Castletownbere, Co Cork, and Killybegs, Co Donegal.

There are a number of different methods for catching fish, with technological advances meaning skippers have detailed real time information at their disposal. Fisheries are classified as inshore, midwater, pelagic or deep water. Inshore targets species close to shore and in depths of up to 200 metres, and may include trawling and gillnetting and long-lining. Trawling is regarded as "active", while "passive" or less environmentally harmful fishing methods include use of gill nets, long lines, traps and pots. Pelagic fisheries focus on species which swim close to the surface and up to depths of 200 metres, including migratory mackerel, and tuna, and methods for catching include pair trawling, purse seining, trolling and longlining. Midwater fisheries target species at depths of around 200 metres, using trawling, longlining and jigging. Deepwater fisheries mainly use trawling for species which are found at depths of over 600 metres.

There are several segments for different catching methods in the registered Irish fleet – the largest segment being polyvalent or multi-purpose vessels using several types of gear which may be active and passive. The polyvalent segment ranges from small inshore vessels engaged in netting and potting to medium and larger vessels targeting whitefish, pelagic (herring, mackerel, horse mackerel and blue whiting) species and bivalve molluscs. The refrigerated seawater (RSW) pelagic segment is engaged mainly in fishing for herring, mackerel, horse mackerel and blue whiting only. The beam trawling segment focuses on flatfish such as sole and plaice. The aquaculture segment is exclusively for managing, developing and servicing fish farming areas and can collect spat from wild mussel stocks.

The top 20 species landed by value in 2019 were mackerel (78 million euro); Dublin Bay prawn (59 million euro); horse mackerel (17 million euro); monkfish (17 million euro); brown crab (16 million euro); hake (11 million euro); blue whiting (10 million euro); megrim (10 million euro); haddock (9 million euro); tuna (7 million euro); scallop (6 million euro); whelk (5 million euro); whiting (4 million euro); sprat (3 million euro); herring (3 million euro); lobster (2 million euro); turbot (2 million euro); cod (2 million euro); boarfish (2 million euro).

Ireland has approximately 220 million acres of marine territory, rich in marine biodiversity. A marine biodiversity scheme under Ireland's operational programme, which is co-funded by the European Maritime and Fisheries Fund and the Government, aims to reduce the impact of fisheries and aquaculture on the marine environment, including avoidance and reduction of unwanted catch.

EU fisheries ministers hold an annual pre-Christmas council in Brussels to decide on total allowable catches and quotas for the following year. This is based on advice from scientific bodies such as the International Council for the Exploration of the Sea. In Ireland's case, the State's Marine Institute publishes an annual "stock book" which provides the most up to date stock status and scientific advice on over 60 fish stocks exploited by the Irish fleet. Total allowable catches are supplemented by various technical measures to control effort, such as the size of net mesh for various species.

The west Cork harbour of Castletownbere is Ireland's biggest whitefish port. Killybegs, Co Donegal is the most important port for pelagic (herring, mackerel, blue whiting) landings. Fish are also landed into Dingle, Co Kerry, Rossaveal, Co Galway, Howth, Co Dublin and Dunmore East, Co Waterford, Union Hall, Co Cork, Greencastle, Co Donegal, and Clogherhead, Co Louth. The busiest Northern Irish ports are Portavogie, Ardglass and Kilkeel, Co Down.

Yes, EU quotas are allocated to other fleets within the Irish EEZ, and Ireland has long been a transhipment point for fish caught by the Spanish whitefish fleet in particular. Dingle, Co Kerry has seen an increase in foreign landings, as has Castletownbere. The west Cork port recorded foreign landings of 36 million euro or 48 per cent in 2019, and has long been nicknamed the "peseta" port, due to the presence of Spanish-owned transhipment plant, Eiranova, on Dinish island.

Most fish and shellfish caught or cultivated in Irish waters is for the export market, and this was hit hard from the early stages of this year's Covid-19 pandemic. The EU, Asia and Britain are the main export markets, while the middle Eastern market is also developing and the African market has seen a fall in value and volume, according to figures for 2019 issued by BIM.

Fish was once a penitential food, eaten for religious reasons every Friday. BIM has worked hard over several decades to develop its appeal. Ireland is not like Spain – our land is too good to transform us into a nation of fish eaters, but the obvious health benefits are seeing a growth in demand. Seafood retail sales rose by one per cent in 2019 to 300 million euro. Salmon and cod remain the most popular species, while BIM reports an increase in sales of haddock, trout and the pangasius or freshwater catfish which is cultivated primarily in Vietnam and Cambodia and imported by supermarkets here.

The EU's Common Fisheries Policy (CFP), initiated in 1983, pooled marine resources – with Ireland having some of the richest grounds and one of the largest sea areas at the time, but only receiving four per cent of allocated catch by a quota system. A system known as the "Hague Preferences" did recognise the need to safeguard the particular needs of regions where local populations are especially dependent on fisheries and related activities. The State's Sea Fisheries Protection Authority, based in Clonakilty, Co Cork, works with the Naval Service on administering the EU CFP. The Department of Agriculture, Food and Marine and Department of Transport regulate licensing and training requirements, while the Marine Survey Office is responsible for the implementation of all national and international legislation in relation to safety of shipping and the prevention of pollution.

Yes, a range of certificates of competency are required for skippers and crew. Training is the remit of BIM, which runs two national fisheries colleges at Greencastle, Co Donegal and Castletownbere, Co Cork. There have been calls for the colleges to be incorporated into the third-level structure of education, with qualifications recognised as such.

Safety is always an issue, in spite of technological improvements, as fishing is a hazardous occupation and climate change is having its impact on the severity of storms at sea. Fishing skippers and crews are required to hold a number of certificates of competency, including safety and navigation, and wearing of personal flotation devices is a legal requirement. Accidents come under the remit of the Marine Casualty Investigation Board, and the Health and Safety Authority. The MCIB does not find fault or blame, but will make recommendations to the Minister for Transport to avoid a recurrence of incidents.

Fish are part of a marine ecosystem and an integral part of the marine food web. Changing climate is having a negative impact on the health of the oceans, and there have been more frequent reports of warmer water species being caught further and further north in Irish waters.

Brexit, Covid 19, EU policies and safety – Britain is a key market for Irish seafood, and 38 per cent of the Irish catch is taken from the waters around its coast. Ireland's top two species – mackerel and prawns - are 60 per cent and 40 per cent, respectively, dependent on British waters. Also, there are serious fears within the Irish industry about the impact of EU vessels, should they be expelled from British waters, opting to focus even more efforts on Ireland's rich marine resource. Covid-19 has forced closure of international seafood markets, with high value fish sold to restaurants taking a large hit. A temporary tie-up support scheme for whitefish vessels introduced for the summer of 2020 was condemned by industry organisations as "designed to fail".
