#CoastalNotes - Seven large urban coastal areas are among more than 40 towns nationwide still seeing untreated sewage released into the water supply, the Environmental Protection Agency (EPA) warns.

According to RTÉ News, the EPA says the current situation is in breach of an EU directive issued more than two decades ago.

Yet three large towns – Killybegs in Co Donegal, Ringaskiddy on Cork Harbour and Arklow in Co Wicklow - have been waiting some 13 years for secondary wastewater treatment facilities.

Moreover, it's been found that nearly a third of established secondary treatment plants nationwide do not meet the EU's main effluent standards, prompting serious pollution concerns.

Clifden in Co Galway and the Co Cork towns of Youghal, Cobh and Passage West have also been identified among the bigger urban areas still discharging untreated wastewater into coastal waters.

The news comes just weeks after it was discovered that effluent from an entire town in Co Galway is being piped into a Special Area of Conservation.

#CoastwatchSurvey - Last year's hot summer resulted in an increase of discarded drinks bottles around Ireland's coastline, according to the results of the latest Coastwatch survey.

The Irish Times reports on the findings of the Autumn 2013 coastal count, which concluded in mid-October - and the outcome shows some correlation between the unusually warm and sunny summer months that brought people to the seaside in droves, and an increase in both plastic and glass bottles littered on the shoreline.

The survey results also confirmed the rise in the numbers of jellyfish in Ireland's warming waters, as previously reported on Afloat.ie.

#Pollution - Three dead calves found in a stream that flows into one of Roscommon town's main water sources have been alleged as the source of two outbreaks of the parasitic disease cryptosporidiosis that have seen 13 people treated for stomach-related complaints, as RTÉ News reports.

Council visits to farms in the catchment area of Roscommon's central water supply scheme have since identified 11 cases of poor management of run-off out of 66 occasions.

Residents in Roscommon and Boyle are still being asked to boil all tap water at home until further notice, and have been warned that home filters will not make the water potable.

#CoastalNotes - More than 97% of Ireland's bathing areas meet the EU's minimum standards for water quality in new figures announced today 2 May - though 21 waters have been stripped of the top ranking.

The latest figures for 2012 were released today in a new report from the Environmental Protection Agency (EPA), whose director general Laura Burke said that the "quality of Ireland's bathing waters remained very high despite remarkably wet summer weather in 2012".

As reported last year on Afloat.ie, water runoff from heavy summer flooding led to elevated levels of E.coli in many coastal areas, causing the temporary closure of beaches in Cork, Galway and North Dublin.

It's this rise in levels of harmful bacteria above mandatory EU safety levels that resulted in the poor performance of some perennial bathing favourites in the 2012 figures, as The Irish Times reports.

The number of beaches meeting the EU's stricter 'good' bathing quality standards fell from 112 in 2011 to 91 waters last year.

EPA senior scientific officer Peter Webster told The Irish Times that the fall "is disappointing but I'm surprised it was not more".

And despite the drop, three local authorities - Dun Laoghaire-Rathdown, Sligo and Leitrim - managed to achieved 'good' status for all of their designated bathing areas.

The worst performing beaches were Clifden in Galway, Fountainstown in Cork, Ballyheigue in Kerry and Rush in North Dublin, all of which were ranked as 'poor' for water quality.

Remedial water treatment works are planned for Clifden, while it's reported that no cause was found for a single "uncharacteristically high" sample taken from Ballyheigue.

#FishKill - Accidental pollution from a farm in Co Kerry has resulted in a fish kill on a tributary of the Ballyline River.

Inland Fisheries Ireland were contacted by Kerry County Council on Saturday 16 March after being altered by a farmer to a slurry spill on his property in the Kilgarvan area of Ballylongford.

Upon arriving at the farm, IFI officers found one side of the slurry pit wall had collapsed, resulting in a large slurry spill. Two cattle were also injured in the incident and had to be put down. 

The slurry went into a watercourse that eventually flows into the Shannon Estuary at Ballylongford Bay.

The farmer had carried out emergency measures on site attempting to contain the slurry and also trying to minimise the impact to fish and wildlife downstream.

Fisheries officers carried out a visual inspection downstream but as the slurry was still passing there was strong discolouration and so it was impossible to see any dead fish. Samples were taken and sent for analysis immediately.

The situation was monitored over the weekend, and a full walkover of the stream was carried out as the water cleared on Tuesday 19 March.

IFI can confirm that a fish kill took place as a result of the pollution incident, and that 150 brown trout, hundreds of stickleback, one eel and one flounder were recovered. The section of river downstream from the farm to Gortanacooka Bridge was the most heavily impacted.

Currently there is a buildup of organic sediment in the river from the farm to the first bridge in Graffa Bog, which IFI says will not disperse until there is a flood in the river. 

The farm was also inspected on the evening of 19 March and the water within the watercourse was clear. The investigation continues.

#MarineScience - A green cleaning brand plans to use science to recycle plastic waste from the sea in the production of a new type of sustainable plastic bottle.

The Guardian reports that Belgian firm Ecover is working with plastic manufacturer Logoplaste to combine plastic taken from the sea with recycled plastic and a type of plastic made from sugar cane known as Plantastic.

Chief executive Philip Malmberg said: "We won't have a definitive figure on the amount we will retrieve, we are just hoping to get as much as is possible and give fishermen an incentive to join the initiative and help clean the seas."

Plastic waste accounts for almost 60% of all litter on Britain's beaches, according to stats from the Marine Conservation Society - and can also cause great harm to marine wildlife, after recent reports that a sperm whale washed up dead in Spain had swallowed 17kg of plastic waste dumped by farmers growing vegetables for UK supermarkets.

It's hoped that boats can be outfitted with special equipment that will allow them to collect up to eight tonnes of plastic waste for recycling - and that fishermen can deposit any plastic they collect at designated points.

#COASTAL NOTES - Coastwatch Ireland has urged for the plastic bag levy to be applied to sanitary products, balloons, lighters and other disposables that can be harmful to Ireland's marine wildlife.

The Irish Times reports on the call from the environmental network's Irish director Karin Dubsky at yesterday's launch of the findings from the recent 25th anniversary survey of Ireland's coastline.

As reported on Afloat.ie in October, the month-long volunteer survey took in use of land and shore, water quality, pollution levels and marine wildlife and plantlife.

More than 18,000 drinks containers - mostly plastic bottles - were found by volunteers on the 3% of Irish coastline sampled for the survey.

And despite a 50% fall over 14 years, sanitary waste such as condoms and dirty nappies were still a problem on beaches.

While suggesting a broadening of the plastic bag levy, Dubsky also called for a 'deposit on return' scheme for drinks containers to reduce letter and encourage recycling.

The survey also reported more positive news, with nitrate levels in outflow waters below detection in half the surveyed areas for the first time since 1993.

#SELLAFIELD - Radioactive waste stored at Sellafield poses an "intolerable risk" to the environment, according to the UK's National Audit Office.

RTÉ News reports that a new study from the British government department watchdog highlights the failure of successive operators of the UK's largest nuclear plant to properly dispose of waste from the facility over more than 50 years.

The complex, on the coast of the Irish Sea in Cumbria, is said to contain enough contaminated waste to fill 27 Olympic-sized swimming pools.

#MARINE WILDLIFE - Marine experts are calling on the UK public to pile pressure on their government to create Marine Conservation Zones (MCZs) to help protect and restore marine wildlife in the Irish Sea and around the British coast.

The Living Seas North West Conference in Cumbria recently was a call to arms for marine experts and the public to join forces to protect the oceans.

And organisers the North West Wildlife Trusts used the event to press support for nature reserves in the Irish Sea as part of a UK-wide campaign by The Wildlife Trusts for 127 MCZs around the United Kingdom.

Callum Roberts, Professor of Marine Conservation at the University of York, described areas off the Isle of Man which have never been dredged as “carpeted with life”.

He said: “In the 19th century the Irish Sea bed was crusted with oysters. Today it is not just a sea different in the quantity of the wildlife it is different in the quality of the habitats in which that wildlife lives.”

Prof Roberts described how a study showed that dredging to catch 28,000 prawns also caught 12,000 other fish, most of which were thrown away. He also spoke of dives where he has seen the seabed damaged in huge areas by trawling.

“Over-fishing is not the only thing going on in the oceans," he said, "they are also affected by climate change and pollution. Our seas are changing faster than at any other time in human history.”

Prof Roberts said he was not against fishing, but that conservationists and the fishing industry need to find some common ground. “The prosperity of wildlife and the fishing industry depend on it," he said.

Meanwhile, The Wildlife Trusts marine protected areas manager Richard White spoke about the problems caused "by all the things that human activity is doing wrong".

He added: "We are trying to increase the resilience of our marine wildlife. The critical part is that we are doing this by trying to create Marine Conservation Zones.”

Pollution was highlighted by TV star and diver Paul Rose and Caroline Salthouse of the North West Coastal Forum.

“A huge problem is ocean debris," said Rose. "In 43 years of diving I am beginning to see more plastic and less fish. It is an issue that we must use to get people engaged in what is going on in our seas.”

Salthouse called for the public not only to sign the Wildlife Trusts’ new 'Petition Fish', but also to write to the British government as individuals.

#CORK HARBOUR NEWS - The head of the team working on the clean-up of the toxic dump on Haulbowline Island says the site could be made safe by the end of 2015, as the Irish Examiner reports.

More than a year ago the Government signed off on a €40 million package to begin the clean-up of the toxic waste site at the former Irish Steel/Ispat plant in Cork Harbour, which closed more than a decade ago.

The site contains an estimated 500,000 tonnes of waste, including toxic heavy metals and various cancer causing materials such as Chromium 6.

Minister for the Marine Simon Coveney tasked Cork County Council with responsibility for managing the clean-up operation, which is scheduled to finally begin by mid-2014, according to project manager Dr Cormac Ó Súilleabháin.

In the meantime, the council must lodge an application for a waste permit licence with the Environmental Protection Agency (EPA).

Dr Ó Súilleabháin added that an analysis of the results from a risk assessment of the site in June last year had led to the conclusion that the majority of the waste should be left on the site, sealed off and topped.

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.
