Inland Fisheries Ireland (IFI) has confirmed that it is seeking a judicial review into the granting of an aquaculture licence for Atlantic salmon at in Bantry Bay.

As the matter is due before the High Court tomorrow, Tuesday 28 September, and the State agency with responsibility for the protection and conservation of freshwater fish and habitats says “it will not be possible…to make any further comments at this stage in the process”.

As previously reported on Afloat.ie, a licence was granted by the Aquaculture Licences Appeals Board this summer — following a protracted appeals process over several years — to Mowi Ireland for an 18-pen facility at Shot Head in Co Cork.

TheJournal.ie reports that Ireland’s largest operator of salmon farms has been granted a licence for an 18-pen facility in Bantry Bay.

Nine years ago Afloat.ie noted proposals for the salmon farm at Shot Head, with local campaigners arguing then that Bantry Bay had reached its capacity for aquaculture.

Following a protracted appeals process over several years, Mowi Ireland has now been given the go-ahead to harvest as much as 2,800 of salmon every two years.

However the proposals remain strongly opposed by locals, environmental groups and even State agency Inland Fisheries Ireland, with concerns over the impact of salmon farming on marine biodiversity.

The latest investigation from TheJournal.ie’s Noteworthy platform looks at the impact of salmon farming on marine biodiversity — and the findings make for sober reading.

Concerns over the impact on wild Atlantic salmon from sea lice and disease in salmon farms, as well as farm escapes that threaten hybridisation, are high on the agenda.

In spite of claims that the State’s monitoring system is “robust” and is “representing best practice”, Ireland received a rating of unsatisfactory from the North Atlantic Salmon Conservation Organisation (NASCO) earlier this year.

One study has identified a possible link between reduced salmon runs and high rates of sea lice infestation in salmon aquaculture projects over a 30-year period.

And methods of controlling sea lice have not escaped scrutiny, either, with the practice of harvesting wrasse from sensitive reef habitats to act as ‘cleaner fish’ raising concern.

Meanwhile, it’s emerged that 22 salmon farms in the State have expired licences and are missing environmental assessments required under EU law.

Documents seen by Noteworthy reveal tensions within the Department of the Marine as to its handling of potential licence breaches, which may include discharges of ammonia and phosphates.

The investigation also reveals that the National Parks and Wildlife Service (NPWS) issued 11 licences to shoot seals — a protected species — to salmon farms between 2015 and 2020, with at least five seals believed to have been killed as a result. Seal Rescue Ireland argues that there is “no scientific support” for this cull.

A resolution by Green MEP for Ireland South, Grace O'Sullivan, calling on the Commission to block the use of a toxic neonicotinoid in the EU's fish farms will be voted this week by the European Parliament's Committee on the Environment, Public Health and Food Safety.

The Imidacloprid pesticide, which has been linked to biodiversity loss and a decline in bee populations, has been banned in the EU for certain agricultural uses on land. There is mounting evidence that the use of this neonicotinoid has a devastating impact on rivers and waterways and its use in Japan has been linked to a dramatic collapse of fish stocks.

Despite this, the European Commission is proposing to establish a Maximum Residue Level for Imidacloprid, which will clear the way for the pesticide's use in EU aquaculture as a treatment for sea lice.

Speaking before the Committee meeting today, Grace O'Sullivan said "I am very concerned by the Commission's proposal which would allow the use of dangerous neonicotinoids in fish farming. We know that this very chemical has devastating impacts on the environment and biodiversity. For this very reason the EU already banned its use on certain crops, a decision more recently upheld by the European Court of Justice. If Imidacloprid is too damaging to go on our crops, how can we accept it in our marine environment?"

The objection was considered in Committee on Thursday, 27 May 2021, and a vote will take place this morning, Friday, May 28th.

The Board of Inland Fisheries Ireland has welcomed new research by scientists from Inland Fisheries Ireland and Argyll Fisheries Trust (Scotland) which found that sea trout carry significantly higher levels of sea lice infestation closer to marine salmon farms. Researchers examined sea lice levels over 25 years from more than 20,000 sea trout. The sea trout were sampled from 94 separate river and lake systems in Ireland and Scotland at varying distances from salmon farms.

The research revealed that sea trout captured closer to salmon farms had significantly higher levels of lice infestation and were found to be of reduced weight. Sea trout are known to remain for extended periods in near-coastal waters where the majority of salmon farms are located. This fish is therefore particularly vulnerable to sea lice impact, having the potential to encounter lice of farm origin throughout much of its marine life.
The effect of the increased lice infestation was most evident in years of less rainfall, when a sea trout of average length (180mm) caught within 10 kilometres of a farm could weigh up to 10g less than fish of similar length caught more than 40 kilometres from a farm. The study covered the entire coasts of West Ireland and Scotland and accounted for variability in temperature and rainfall.
The research article entitled ‘Aquaculture and environmental drivers of salmon lice infestation and body condition in sea trout’ was authored by Dr. Samuel Shephard and Dr. Paddy Gargan of Inland Fisheries Ireland alongside Craig MacIntyre of the Argyll Fisheries Trust. It was published in the international journal Aquaculture Environment Interactions in October.
Studies have shown that the impact of sea lice in farmed areas on sea trout has been substantial with increased mortality, reduced body condition and a changed migratory behavior reported. Heavily liced sea trout return to freshwater prematurely to rid themselves of lice and exhibit very poor marine growth and greatly reduced marine survival. In fact, the most heavily lice infested sea trout die at sea. Rod catch data from 18 Connemara fisheries from 1974 to 2014 show a collapse in rod catch over the 1989/1990 period (see Figure 1). This collapse has been linked to lice infestation from salmon farms while recovery of sea trout rod catches to pre collapse levels has not occurred.
Sea trout offer significant angling value while traditionally the species was abundant on the west coast of Ireland. Angling is worth €836 million to the Irish economy every year and supports upwards of 11,000 jobs, often in rural and peripheral communities. Inland Fisheries Ireland carries out research across fish populations, their habitats and the ecosystem with a view to informing the protection and conservation of this precious resource.
Dr. Paddy Gargan, Senior Research Officer at Inland Fisheries Ireland and one of the report authors, said: “”While there had been some improvement in sea lice control in recent years, lice control on salmon farms was still not sufficient in certain west of Ireland bays during the spring migration period for sea trout to avoid heavy lice infestation and increased marine mortality. More effort is required to ensure lice levels on salmon farms are adequately controlled at this critical period when sea trout leave freshwater and enter the sea.”
Dr. Cathal Gallagher, Head of Research and Development at Inland Fisheries Ireland said: “The finding that salmon farming is responsible for increased sea lice infestation and for significantly reduced body condition in sea trout may have implications for current lice control management strategies. This research will inform coastal zone planning of aquaculture in the future and contribute towards the avoidance of potential impact on sea trout stocks.
Inland Fisheries Ireland is committed to protecting and conserving our fish populations and this research is crucial in managing the sea trout species in Ireland. This country is known as a unique angling destination as a result of its indigenous wild fish species and beautiful scenery. Continued investment in research is necessary to ensure the conservation and protection of our fisheries resource.”

Salmon farmers have been reminded of the dangers of egg-bearing lice, despite a "sustained reduction" in their numbers according to a new report.
"Pest control will always remain a challenge requiring active management," said Minister of State for Fisheries Sean Connick, as quoted by The Irish Times.
The minister spoke at the launch of a report by the National Implementation Group (NIG) for improving pest control in Ireland's salmon farms.
The report noted that the majority of facilities maintained lice level below trigger levels for treatment, and where treatment was necessary it was conducted effectively.
In response to the report, Salmon Watch Ireland (SWI) claims that the risks to wild salmonids "by inadequately regulated salmon farming" are being ignored, threatening juvenile salmon and sea trout.
It also highlighted the fact that Ireland is being pushed by the European Commission to conform salmon farming to EU Habitats Directive standards for wild salmon.
"The reality is that the regulation of the salmon farming industry is a shambles," said the SWI in a statement.

Ireland's Offshore Renewable Energy

Because of Ireland's location at the Atlantic edge of the EU, it has more offshore energy potential than most other countries in Europe. The conditions are suitable for the development of the full range of current offshore renewable energy technologies.

Offshore Renewable Energy FAQs

Offshore renewable energy draws on the natural energy provided by wind, wave and tide to convert it into electricity for industry and domestic consumption.

Offshore wind is the most advanced technology, using fixed wind turbines in coastal areas, while floating wind is a developing technology more suited to deeper water. In 2018, offshore wind provided a tiny fraction of global electricity supply, but it is set to expand strongly in the coming decades into a USD 1 trillion business, according to the International Energy Agency (IEA). It says that turbines are growing in size and in power capacity, which in turn is "delivering major performance and cost improvements for offshore wind farms".

The global offshore wind market grew nearly 30% per year between 2010 and 2018, according to the IEA, due to rapid technology improvements, It calculated that about 150 new offshore wind projects are in active development around the world. Europe in particular has fostered the technology's development, led by Britain, Germany and Denmark, but China added more capacity than any other country in 2018.

A report for the Irish Wind Energy Assocation (IWEA) by the Carbon Trust – a British government-backed limited company established to accelerate Britain's move to a low carbon economy - says there are currently 14 fixed-bottom wind energy projects, four floating wind projects and one project that has yet to choose a technology at some stage of development in Irish waters. Some of these projects are aiming to build before 2030 to contribute to the 5GW target set by the Irish government, and others are expected to build after 2030. These projects have to secure planning permission, obtain a grid connection and also be successful in a competitive auction in the Renewable Electricity Support Scheme (RESS).

The electricity generated by each turbine is collected by an offshore electricity substation located within the wind farm. Seabed cables connect the offshore substation to an onshore substation on the coast. These cables transport the electricity to land from where it will be used to power homes, farms and businesses around Ireland. The offshore developer works with EirGrid, which operates the national grid, to identify how best to do this and where exactly on the grid the project should connect.

The new Marine Planning and Development Management Bill will create a new streamlined system for planning permission for activity or infrastructure in Irish waters or on the seabed, including offshore wind farms. It is due to be published before the end of 2020 and enacted in 2021.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE. Is there scope for community involvement in offshore wind? The IWEA says that from the early stages of a project, the wind farm developer "should be engaging with the local community to inform them about the project, answer their questions and listen to their concerns". It says this provides the community with "the opportunity to work with the developer to help shape the final layout and design of the project". Listening to fishing industry concerns, and how fishermen may be affected by survey works, construction and eventual operation of a project is "of particular concern to developers", the IWEA says. It says there will also be a community benefit fund put in place for each project. It says the final details of this will be addressed in the design of the RESS (see below) for offshore wind but it has the potential to be "tens of millions of euro over the 15 years of the RESS contract". The Government is also considering the possibility that communities will be enabled to invest in offshore wind farms though there is "no clarity yet on how this would work", the IWEA says.

Based on current plans, it would amount to around 12 GW of offshore wind energy. However, the IWEA points out that is unlikely that all of the projects planned will be completed. The industry says there is even more significant potential for floating offshore wind off Ireland's west coast and the Programme for Government contains a commitment to develop a long-term plan for at least 30 GW of floating offshore wind in our deeper waters.

There are many different models of turbines. The larger a turbine, the more efficient it is in producing electricity at a good price. In choosing a turbine model the developer will be conscious of this ,but also has to be aware the impact of the turbine on the environment, marine life, biodiversity and visual impact. As a broad rule an offshore wind turbine will have a tip-height of between 165m and 215m tall. However, turbine technology is evolving at a rapid rate with larger more efficient turbines anticipated on the market in the coming years.

 

The Renewable Electricity Support Scheme is designed to support the development of renewable energy projects in Ireland. Under the scheme wind farms and solar farms compete against each other in an auction with the projects which offer power at the lowest price awarded contracts. These contracts provide them with a guaranteed price for their power for 15 years. If they obtain a better price for their electricity on the wholesale market they must return the difference to the consumer.

Yes. The first auction for offshore renewable energy projects is expected to take place in late 2021.

Cost is one difference, and technology is another. Floating wind farm technology is relatively new, but allows use of deeper water. Ireland's 50-metre contour line is the limit for traditional bottom-fixed wind farms, and it is also very close to population centres, which makes visibility of large turbines an issue - hence the attraction of floating structures Do offshore wind farms pose a navigational hazard to shipping? Inshore fishermen do have valid concerns. One of the first steps in identifying a site as a potential location for an offshore wind farm is to identify and assess the level of existing marine activity in the area and this particularly includes shipping. The National Marine Planning Framework aims to create, for the first time, a plan to balance the various kinds of offshore activity with the protection of the Irish marine environment. This is expected to be published before the end of 2020, and will set out clearly where is suitable for offshore renewable energy development and where it is not - due, for example, to shipping movements and safe navigation.

YEnvironmental organisations are concerned about the impact of turbines on bird populations, particularly migrating birds. A Danish scientific study published in 2019 found evidence that larger birds were tending to avoid turbine blades, but said it didn't have sufficient evidence for smaller birds – and cautioned that the cumulative effect of farms could still have an impact on bird movements. A full environmental impact assessment has to be carried out before a developer can apply for planning permission to develop an offshore wind farm. This would include desk-based studies as well as extensive surveys of the population and movements of birds and marine mammals, as well as fish and seabed habitats. If a potential environmental impact is identified the developer must, as part of the planning application, show how the project will be designed in such a way as to avoid the impact or to mitigate against it.

A typical 500 MW offshore wind farm would require an operations and maintenance base which would be on the nearby coast. Such a project would generally create between 80-100 fulltime jobs, according to the IWEA. There would also be a substantial increase to in-direct employment and associated socio-economic benefit to the surrounding area where the operation and maintenance hub is located.

The recent Carbon Trust report for the IWEA, entitled Harnessing our potential, identified significant skills shortages for offshore wind in Ireland across the areas of engineering financial services and logistics. The IWEA says that as Ireland is a relatively new entrant to the offshore wind market, there are "opportunities to develop and implement strategies to address the skills shortages for delivering offshore wind and for Ireland to be a net exporter of human capital and skills to the highly competitive global offshore wind supply chain". Offshore wind requires a diverse workforce with jobs in both transferable (for example from the oil and gas sector) and specialist disciplines across apprenticeships and higher education. IWEA have a training network called the Green Tech Skillnet that facilitates training and networking opportunities in the renewable energy sector.

It is expected that developing the 3.5 GW of offshore wind energy identified in the Government's Climate Action Plan would create around 2,500 jobs in construction and development and around 700 permanent operations and maintenance jobs. The Programme for Government published in 2020 has an enhanced target of 5 GW of offshore wind which would create even more employment. The industry says that in the initial stages, the development of offshore wind energy would create employment in conducting environmental surveys, community engagement and development applications for planning. As a site moves to construction, people with backgrounds in various types of engineering, marine construction and marine transport would be recruited. Once the site is up and running , a project requires a team of turbine technicians, engineers and administrators to ensure the wind farm is fully and properly maintained, as well as crew for the crew transfer vessels transporting workers from shore to the turbines.

The IEA says that today's offshore wind market "doesn't even come close to tapping the full potential – with high-quality resources available in most major markets". It estimates that offshore wind has the potential to generate more than 420 000 Terawatt hours per year (TWh/yr) worldwide – as in more than 18 times the current global electricity demand. One Terawatt is 114 megawatts, and to put it in context, Scotland it has a population a little over 5 million and requires 25 TWh/yr of electrical energy.

Not as advanced as wind, with anchoring a big challenge – given that the most effective wave energy has to be in the most energetic locations, such as the Irish west coast. Britain, Ireland and Portugal are regarded as most advanced in developing wave energy technology. The prize is significant, the industry says, as there are forecasts that varying between 4000TWh/yr to 29500TWh/yr. Europe consumes around 3000TWh/year.

The industry has two main umbrella organisations – the Irish Wind Energy Association, which represents both onshore and offshore wind, and the Marine Renewables Industry Association, which focuses on all types of renewable in the marine environment.
