Afloat reader Lee Maginnis has shared a new image of the suction dredger Charnock returning to Warrenpoint in Co Down after emptying its load in the open sea on Sunday (24 March).

As previously reported on Afloat.ie, the vessel has been carrying out dregding operations in the approaches and deep-water berths of the inner harbour of Warrenpoint Port since the end of February.

These operations are expected to continue until mid April.

Annual maintenance dredging at Warrenpoint Harbour in County Down will continue until the end of March and possibly into April.

According to Afloat reader Lee Maginnis, residents and visitors to Warrenpoint and, indeed, Omeath have been treated to the sight of the trailing suction dredger "Charlock" hard at work over recent weeks.

The dredging, say the harbour authorities, will 'secure the safety and accessibility of the shipping channel for commercial and recreational purposes'.

Since the end of February Charlock has been carrying out operations in the approaches and deep-water berths of the inner harbour of Warrenpoint Port, an operation that will take approximately 48 days.

The sleek, grey ship, with a bulbous bow transports dredged material to the WARRENPOINT B licenced sea disposal site outside the lough.

The Charlock is supported by the "Forth Trojan" workboat vessel, which will undertake bed levelling operations.

Dredging work is about to begin at the Port of Waterford with a maintenance dredging campaign to be carried out by a Dutch company.

Baggerbedrijf De Boer B.V.'s trailing suction hopper dredger Amazone is next week to conduct activities in the vicinity of Belview, Cheekpoint and further down in the estuary at the Duncannon Bar.

The campaign's main objective is the removal of accumulated sediment from the channels, turning areas and berths at (Belview) the main terminal at the Port of Waterford. This work will mostly involve work at the Cheekpoint lower bar and also at the Duncannon Bar.

The removed material will then be disposed by the 2771m3 hopper capacity dredger at an approved site beyond the estuary at a location south west of Hook Head.

It is expected that the campaign will take approximately 28 days and be followed by a bed levelling works by the Fastnet Sound which Afloat adds is a 21m MulitCat operated by a local firm Fastnet Shipping.

The marine plant and services company is based on the River Suir at Bilberry which is just westward of Waterford city's Rice lift-bridge.

One of the country’s leading marinas will become unusable for keelboats unless urgent action is taken to address increasing silting in the harbour area writes David Forsythe in West Cork

Kinsale-based Fine Gael councillor Kevin Murphy told the recent meeting of Cork County Council’s Western Division that the issue was among the most serious he had ever had to bring to the attention of the council.

“The story is that Kinsale Harbour itself has severe silting at the yacht marina and around pier head itself. A substantial number of the keelboats are bottoming out now. This is a very serious issue and a very expensive one to sort out because there is a substantial dredging to be done,” he said.

Matthias Hellstern, Commodore of the Kinsale Yacht Club said that the issue had become much more serious in the last few years and the rate of silting in Kinsale Harbour seemed to be increasing.
“During Covid there was obviously a lot less activity at the marina and in the harbour in general because of the restrictions. It has been happening over a number of years but seems to be getting much worse now. It is something that we really need to address urgently,” he said.

The 200 berth marina brings in some 3,500 visiting boat nights to the town every year contributing an estimated €525,000 to the local economy according to the yacht club’s own estimates. A non-profit organisation run by volunteers, it is one of only three yacht clubs in the country that owns its own marina, the others being Howth Yacht Club and the Royal Cork Yacht Club in Crosshaven.
“We have visitors coming from France, the UK, Spain, Germany, the USA and all around Ireland,” said Matthias Hellstern, “and we run also run national and international sailing championships which we could not do without the marina facility.”

The KYC is due to host the upcoming Squib UK National Championships, Dragon Gold Cup and also hosts the biennial Sovereign’s Cup, but silting is already causing problems for events in Kinsale.
“We hosted the April Spring series recently and we were having yachts running aground at low tide,” said Matthias, “they simply couldn’t get out of the marina and obviously that’s a serious problem.”
Mr Hellstern said that already about 25% of the marina was not useable for keelboats at low tide.

“At the moment we can move things around a bit. The berths furthest from the channel are most affected so we can put power boats, boats without keels in there for the time being but as the silting gets worse more and more of the marina will be affected.”

Cllr Kevin Murphy said that silting was affecting other users of the harbour as well across leisure, fishing and commercial sectors.

“We have to at all times ensure Kinsale continues being useable for leisure and also commercial and fishing, it’s all three. The Kinsale Yacht Club will help out with a survey that needs to be done on the silting and I would expect that the county council will also chip in if we can to help out in their endeavours to get that done as soon as possible.”

Cllr Murphy said that he would put down a notice of motion at the next municipal district meeting to have all of the stakeholders attend a meeting at Kinsale Yacht Club, “to make sure this is addressed as soon as possible”.

Responding to Cllr Murphy, Kevin Morey, Director of Water Services at Cork County Council said, “We will engage just to take stock and see what is the issue there. From your description, it sounds like it might be quite a significant one and we are aware from other locations that that could bring us into quite complex and protracted processes. Let’s start looking first and take stock so we’ll get back to you on that and arrange some kind of assessment on site.”

Environmental campaigners have hit out at a Stormont decision to approve sand dredging in Lough Neagh, as the Belfast Telegraph reports.

Sand dredging has been practiced in Lough Neagh since the 1930s, with no permission needed until after the lough was designated as a Special Protection Area for wildlife in 1999.

Most recently the practice has been subject of a years-long legal battle, as previously reported on Afloat.ie, with Friends of the Earth claiming that as much as 1.5 million tonnes of sand are removed from the lough each year.

The final say on the matter was left to Northern Ireland’s Department of Infrastructure, whose minister Nichola Mallon signed off on the approval and said the decision was a “finely balanced” one “where I had to weigh up the various benefits with the potential for harm to the designation features of the lough”.

Among those criticising the move was Green Party NI leader Clare Bailey.

She said that sand dredging has “a devastating impact on the entire ecosystem of the lough”, and claimed the situation underscored the notion that “Northern Ireland is disintegrating into an environmental wasteland”.

The Dublin Port Company has given notice that maintenance dredging will take place between Alexandra Basin and the Dublin Bay Buoy from tomorrow, Thursday 10 September.

Four weeks of dredging works are scheduled in the fairway and berth pockets from the buoy to a line drawn due south of berth OB1 and including Alexandra Basin East.

Three vessels will be involved in the dredging works: the trailing suction hopper dredger Shoalway; the survey vessel Smit Neyland; and Norma, a bed-levelling plough.

The three craft will maintain a listening watch on VHF Channel 12 and show the required lights and shapes.

All other vessels should pass at slow speed and make due allowance for their operations and restricted manoeuvrability.

The Port of Cork reminds mariners that maintenance dredging will be taking place in Cork Harbour on all main shipping channels and berths from this Wednesday 19 August.

As previously reported on Afloat.ie, the dredging campaign by the TSHD Taccola will progress 24 hours a day until late September.

It follows a prior survey conducted last week, and bed levelling operations which began yesterday, Sunday 16 August.

Mariners are requested to navigate with caution when in the vicinity of the work craft, to pass by as wide a margin as possible and proceed with minimum wash and speed.

A maintenance dredging campaign has begun in recent days at the Port of Waterford where activities will involve the waters of Duncannon Bar, Cheekpoint, and at the port's main terminal at Belview, writes Jehan Ashmore

Prior to the operations at the south-east port, the Cypriot flagged Shoalway, a trailing suction hopper dredger had been carrying out operations for the Dublin Port Company. Shoalway sailed from the capital to arrive on the Waterford Estuary on Sunday. 

According to the Port of Waterford (click to consult campaign notice here), the dredger will dispose spoil at an approved site south west of Hook Head, Co. Wexford. Dredging will be followed by a bed levelling campaign by the vessels, Fastnet Sound and or the Glenesk.

Afloat adds that Irish Dredging which is a subsidiary of Royal Boskalis Westminster nv, the world’s largest dredging group, was given the contract from the Port of Waterford. The extensive fleet of the Dutch group provides Irish Dredging access to the use a of wide range of vessels for projects around the Irish coast.

Further tracking of the Shoalway since introduction on the Waterford Estaury has seen the 90m long dredger kept busy between Cheekpoint to the spoiling grounds out to sea.

The campaign according to the Port of Waterford is expected to last approximately 24 days.

#Irishports - The Port of Waterford have issued a Marine Notice in recent days to advise all ship owners, shipmasters, agents, fishing vessels, pleasure craft users, seafarers and fishery organisations of a dredging campaign, writes Jehan Ashmore.

The dredging operation along Waterford Estuary began in mid-March and according to the south-east multi-modal Port the campaign will continue until around 6 April.

Carrying out these works is the task of trailing suction hopper dredger Freeway which will conduct dredging activities in the vicinity of Belview Port. The lo-lo facility located downriver of Waterford City is the main port along the estuary.

Freeway is operated by UK firm, Royal Boskalis Westminster based in Hampshire. They are no strangers to these waters having been contracted previously by the port and more recently from the Dublin Port Company. Due to berth capacity constraints the 92m dredger during December had to dock in Dun Laoghaire Harbour.

On this occasion, Freeway's role on Waterford Estuary will include duties carried off Cheekpoint and at the Duncannon Bar located further downriver and beyond where the Passage East ferry links to Ballyhack.

Disposal material from Freeway will take place at an approved site south west of Hook Head. Following such work a bed-levelling campaign will be assigned to the Waterford City based catamaran craft Fastnet Sound.

The Department of Agriculture, Food and the Marine has updated local Fingal councillors on its proposals for the dredging of Howth Harbour.

On his Facebook page, Cllr Cian O’Callaghan says the meeting with the department and the Howth Harbour Master on Wednesday (6 March) detailed a plan to dredge five key areas of the harbour, namely:

  • The fishing trawler basin between the West Pier and Middle Pier
  • The approach channel at the mouth of the harbour
  • The marina used by Howth Yacht Club
  • The approach channel to the marina
  • The outer moorings area which is used by the Howth Sailing and Boat Club

This would result in the extraction of 225,000 cubic metres of silt, the equivalent of up to 30,000 lorry loads, says Cllr O’Callaghan.

The detailed plan follows testing of material extracted from the harbour which confirms that while is it contaminated by general harbour activity, it is not considered hazardous.

It is being proposed that the spoil be treated and used to create a 100-metre-wide infill area along the west side of the present West Pier. Plans for the use of this new space have not yet been decided but it is expected there will be a relevant public consultation by year’s end.

Four months ago the tender period closed for engineering services related to these long-awaited dreading works in the North Co Dublin harbour.

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.
