#Seabin - Ards and North Down Borough Council wants to bring in the Seabin to help clean up the coastline of the Ards Peninsula, as the Belfast Telegraph reports.

The council plans to purchase 10 of the devices — which capture floating debris in harbours and marinas — in what’s being touted as a first for Northern Ireland.

Earlier this year, Dun Laoghaire Harbour in Dublin saw the installation of its first Seabin thanks to the campaigning efforts of local girl Flossie Donnelly.

It’s hoped that the move by Ards councillors will see further take up around the Northern Irish coast.

#Microplastic - The West of Ireland is one of only three sites sampled out of 75 during the Volvo Ocean Race with no trace of microplastic particles.

South of Australia and east of Argentina were the other sites found clear of microplastic in findings that give a clear mandate for positive and decisive action from national governments, international organisations, business and individuals to stop plastic polluting our seas.

The most recent data collected, before the race finale in The Hague, by scientific devices on board Team AkzoNobel and Turn the Tide on Plastic found particularly high levels of microplastics — 224 particles per cubic metre — in Skagerrak, a 150-mile strait that runs between Norway, Sweden and Denmark where the outflow from the Baltic Sea meets the Atlantic Ocean.

The highest levels of microplastic — 349 particles per cubic metre — were found in a sample taken in the South China Sea that feeds into the Kuroshio Current and the North Pacific Gyre.

The second highest, at 307 particles per cubic metre, came close from the point where the Mediterranean Sea and Atlantic Ocean meet at the Strait of Gibraltar.

Even close to Point Nemo, the furthest place from land on Earth, where the nearest humans are on the International Space Station, between nine and 26 particles of microplastic per cubic metre were recorded.

The seawater samples were collected during the course of the 45,000-nautical-mile, eight-month race which passed six continents and 12 landmark host cities. The race began in Alicante last October, finishing in The Hague in June.

Anne-Cecile Turner, sustainability programme leader for the Volvo Ocean Race, said: “We have used a sporting event to collect groundbreaking scientific data to provide a global map of microplastics concentrations — even finding them in some of the remotest places on Earth. 


“Our ambition is that the data will provide a new benchmark for our understanding of the spread of these ubiquitous particles and offer a template for future scientific methodology.

“With the continuation of the sustainability programme, we will continue our mission to inspire, engage and act as a pioneer, with the aim of restoring ocean health.”

Dr Toste Tanhua of the GEOMAR Institute for Ocean Research Kiel, funded by the Cluster of Excellence Future Ocean, analysed the preliminary microplastics data at their laboratory in Kiel, Germany.

The data has since been uploaded to a National Oceanic and Atmospheric Administration (NOAA) database where scientists are able to access it open source.

VOR Microplastic world map

Dr Tanhua said the Volvo Ocean Race Science Programme “has contributed enormously to the understanding of microplastic contribution around the world, and has contributed to a global map of CO2 uptake by the oceans. The race has showed that the race yachts and sailors can be excellent science supporters.”

The boats also collect other oceanographic data measurements including temperature, dissolved CO2, salinity and algae content (as chlorophyll a) that gives an indication of levels of ocean health and acidification and supports quantification of the ocean’s uptake of carbon dioxide.

In parallel, 30 scientific drifter buoys deployed during the race are transmitting data that is essential for forecasting of weather and climate changes, in both the short and long term. This is being utilised by the World Meteorological Organisation and UNESCO’s Intergovernmental Oceanographic Commission.

The Volvo Ocean Race Science Programme is funded by Volvo Cars, which is donating €100 from the first 3,000 sales of the new Volvo V90 Cross Country Volvo Ocean Race edition to support the initiative.

Microplastics are often invisible to the naked eye and can take thousands of years to degrade. By collecting information on their levels, the science programme is helping scientists gain insight into the scale of plastic pollution and its impact on marine life.

To build upon the programme’s sustainability achievements, it will be embedded at the heart of the race going forward. And in the run up to the next edition, the programme will continue to organise a range of international Ocean Summits, further expand the education programme and continue to pioneer a scientific programme focussing on ocean plastic.

It will also collaborate with a range of innovative partners, including 11th Hour Racing and UN Environment, to help deliver a lasting legacy and drive real change for a healthy planet.

Since the end of the latest race, the sustainability programme convened a workshop with key global stakeholders from science, academia, the private sector and other institutions, including UN Environment and Mirpuri Foundation, to identify the gaps to fill in order to advance our understanding of these issues and to align our missions.

Fiona Ball, head of responsible business at Sky Ocean Rescue, said: “The data that Turn the Tide on Plastic collected throughout Volvo Ocean Race highlights the critical state of our oceans. By supporting the Turn the Tide on Plastic yacht, Sky Ocean Rescue aims to raise awareness and inspire everyone to make simple, everyday changes to stop our oceans from drowning in plastic. We can all play our part and turn off the plastic tap, now is the time for fundamental change to protect our planet.”

#Litter - Only 8% of beaches, harbours and rivers in Ireland can be considered clean, according to the first national survey on littering at waterside spots.

An Taisce investigated 50 sites nationwide on behalf of the Irish Business Against Litter (IBAL) group and found that just four – Salthill in Galway, Kinsale Harbour in Co Cork, Lanesborough and Carrick-on-Shannon – were clean when measured against EU standards.

Outsider.ie has the full survey results, which point at Cork Harbour and the Wild Atlantic Way as among the biggest offenders for litter blight around the coast.

“We know the success of the Wild Atlantic Way is placing strains on infrastructure of various kinds,” said IBAL spokesperson Conor Horgan. “Litter is a likely consequence of this and one local authorities need to manage to ensure the appeal of the way is sustained.”

Among inland waterways, the Boyne in Drogheda, the Shannon at Portumna, the Suir in Waterford city and the Tolka at Annesley Bridge were considered “heavily littered” — mostly by plastic bottles and drinks cans, cigarette butts and plastic sweet wrappers.

In an editorial earlier this week, The Irish Times warned over “the permanent damage being caused to the marine environment in the form of plastic pollution”.

The issue is one that many campaigners around the country are attempting to tackle – including young Flossie Donnelly and her clean-up efforts in Dun Laoghaire Harbour.

It’s also considered a threat to Ireland’s angling resource. “Our waterways and the fish which they sustain are one of our great natural assets,” said Suzanne Campion, head of business development at Inland Fisheries Ireland (IFI).

“Ireland has a reputation as an outstanding angling destination however this is reliant on our ‘green’ image. We are disappointed to learn that angling destinations such as the Boyne, Shannon, Suir and Tolka feature on the ‘heavily littered’ list.”

IFI promotes a ‘leave no trace’ ethos with anglers and all water users, and Campion appealed to the public “to refrain from littering in or around our waterways”.

Campion added: “If we are to ensure the sustainability of the resource in the long term and to safeguard Ireland’s enduring appeal within the world of angling then we each need to quickly remedy this litter issue.”

As previously noted on Afloat.ie, Doolin ferry operator Eugene Garrihy hit out at the IBAL’s claims that the Clare town is a “litter blackspot”.

#Toxic - Pet owners have been advised to be vigilant over an outbreak of toxic blue-green ‘algae’ in a Killarney lake, as The Irish Times reports.

Lough Leane has been signposted by Kerry County Council over the presence of Cyanobacteria that has turned the waters a soupy pea-green colour.

A number of dogs died after exposure to the bacteria during a previous bloom on the lake shore in 2016.

Suspected similar cases have also been reported at Lough Mask as well as waterways further east, including Ballymore Eustace on the River Liffey.

Meanwhile, scientists at the Galway-Mayo Institute of Technology are preparing to use drones to test the water quality of lakes on the West Coast.

GMIT’s Marine and Freshwater Research Centre has secured €132,000 in funding from the EPA for the scheme that will allow for real-time feedback of camera images and data.

Licensed drone pilots will work with lake biologists and water scientists on the two-year project, part of Ireland’s mandate under the EU’s Water Framework Directive.

#MarineWildlife - Concerns have been raised over the levels of plastic pollution at an important gannet colony on the smallest of the Skellig Islands.

As The Irish Times reports, discarded plastic waste – including parts of old fishing gear in the Atlantic for more than a decade – now comprises a large proportion of the material used by some 70,000 gannets to build their nests on Little Skellig.

And conservationists fear the problem is being ignored by authorities focused on marketing nearby Skellig Michael to tourists based on it appearance in recent Star Wars films.

“I film marine life underwater [and] it’s very difficult to get a frame without plastic in it, and that wasn’t an issue 15 years ago,” said local filmmaker Vincent Hyland, who added that plastic pollution levels had reached “frightening proportions” in the last year.

You don’t have to look far to see a scary story involving plastic, whether that story involves a whale washing up to shore as a result of ingesting too much plastic or a video that shows a turtle having a straw pulled out of its nostril, the truth is that plastic pollution has become an epidemic that needs to be taken seriously.

Although plastic waste is everywhere, its detrimental effect on our waterways and marine life have made people take notice of the problem at hand. It is estimated that plastic makes up 60-90% of marine debris, and some of that debris, such as fishing lines can take up to 650 years to break down. 650 years is the equivalent of the whole of the series of Friends playing continuously 4693 times.

Preventing Plastic Pollution in our Waterways

Boaters will be noticing first-hand the problem plastic pollution is causing, with it washing up on riverbanks, blocking weirs and floating next to their marina boat moorings. Luckily not all hope is lost in this cause, there are several steps that boaters can take to ensure the issue doesn’t get any worse and starts to head in the right direction.

For example, use reusable bags instead of opting for single use carrier bags. You could also replace plastic cutlery with bamboo or corn starch cutlery. These are just small changes that could make a big difference.

#Angling - At a sitting of Ardee District Court on Monday 12 March, Irish Water pleaded guilty to the discharge of deleterious matter to the River Dee on 15 May 2017.

The offence related to a poor quality discharge from a wastewater treatment plant at Ardee, Co Louth.

The River Dee rises near Bailieboro in Co Cavan and flows through Co Meath and Co Louth, where it enters the Irish Sea at the village of Annagassan.

Michaela Kirrane, senior fisheries environmental officer with Inland Fisheries Ireland (IFI), told Judge Coughlan that during a routine inspection of the river on the 25 May last year, it was noted that the river appeared to be in a poor condition downstream of the discharge point from Ardee Wastewater Treatment Plant.

A series of water samples were taken and analysis confirmed that the discharge from the treatment plant was having a deleterious impact on the quality of the River Dee, an important brown trout fishery.

Irish Water co-operated fully with IFI’s investigation and remediation works were carried out. Upgrade works are currently underway to increase capacity at the wastewater treatment plant. 

Irish Water was fined €4,500 with costs and expenses awarded to IFI amounting to €4,381.61.

#CoastalNotes - Plastic continues to litter Ireland’s coastline, with over 8,800 drinks bottles recorded around the island’s shores in the 2017 Coastwatch survey.

Preliminary results from the volunteer survey conducted in September and October show that more than four-fifths of shoreline sites had plastic bottles, according to RTÉ News.

While the rate of 3.6 per 100m of shore indicates a downward trend, it is still far higher than those in Scandinavia.

And it comes with a rising rate of bottle tops, especially “complex caps” that come with sports drinks, as The Irish Times reports.

In other summary results ahead of the final report due in the sprint, plastic bags were found at 40% of sites, though their numbers have fallen from a peak of 18 per site before the bag tax to an average of two this year.

While nearly half of locations surveyed were rated as “reliably free” of pollution by sewage, there are concerns over “worrying” nitrate levels in freshwater streams entering the sea.

That’s particularly so on the South and East Coasts, and in Northern Ireland where 13% of sites had levels exceeding EU directives.

#Pollution - RTÉ News reports that a swimming ban was lifted yesterday on bathing spots at Seapoint and Killiney on Dublin Bay’s southern shore after high levels of E.coli were detected last Friday (30 June).

The bathing ban remains at Blackrock Baths pending the results of samples expected later today (Wednesday 5 July). Blackrock and Seapoint were subject to a similar ban for high E.coli levels back in January, according to TheJournal.ie.

More recently, the beaches at Dollymount and Sandymount were closed to swimming after heavy rains caused by a sewage spill in the River Liffey.

#Pollution - The beaches at Dollymount and Sandymount on Dublin Bay have been closed to swimmers after a sewage spill in the Liffey caused by heavy rain on Thursday (8 June).

According to BreakingNews.ie, swimming is banned at both of the popular city bathing spots pending the results from water samples expected tomorrow (Monday 12 June).

It comes just weeks after two Dublin region coastal beaches lost their Blue Flag status in the latest list of EU beach quality awards.

That announcement followed days from the news that three other Dublin beaches — including Merrion Strand, adjacent to Sandymount — had failed to meet the minimum standards for bathing water quality.

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.
