Inland Fisheries Ireland (IFI) is investigating a serious fish kill incident at the Glore River in Kiltimagh, Co Mayo.

Environmental and fisheries officers from the Western River Basin District in Ballina were alerted to the incident on Friday 3 September.

Water and fish samples were taken from the scene and removed for scientific analysis at an independent laboratory.

IFI, the State agency responsible for the protection and conservation of freshwater fish and habitats, estimates that there could be in excess of 500 mortalities of young salmon and trout.

Investigations are ongoing and IFI says it not in a position to comment on the cause of the fish kill at this stage, pending further analysis of samples taken.

The Glore is described as an important spawning river for trout and salmon within the Moy catchment area.

This incident comes just says after Northern Ireland experienced its third fish kill in as many monthstwo of them on the same river in Co Antrim.

Northern Ireland’s inland waters have seen a third fish kill in as many months after hundreds of dead trout were found in a Co Fermanagh river, as BBC News reports.

The grim discovery in the Kesh River on Wednesday (1 September) comes just days after the Three Mile Water in Co Antrim was struck by its second fish kill incident of this summer.

Ian Grimsley of Kesh and District Angling Club said the incident — which claimed not only brown trout and river trout but juvenile salmon, perch and more — was the worst of its kind he had witnessed in the area in 40 years.

And like last week’s fish kill in Newtownabbey, he fears “it’ll take years to bring it back again”.

The Northern Ireland Environment Agency (NIEA) has launched an investigation, with the origin of the river pollutant as yet unknown. BBC News has more on the story HERE.

Co Antrim’s Three Mile Water has been afflicted by a second fish kill this summer — and a local angling group says it could take years to recover.

The Belfast Telegraph reports on the incident which was discovered on the river at Monkstown on Friday afternoon (27 August).

Trout, eels and even flounder that swim upstream from Belfast Lough are among the species affected in what the Three Mile Water Conservation and Angling Association has branded a “major fish kill”.

It comes less than three months after hundreds of trout were believed to have been killed on the same river in an incident the cause of which has not been identified.

Inland Fisheries Ireland (IFI) says it is investigating a serious fish kill incident at Barnagrow Lake near Shercock in Co Cavan, within the Annalee River and Upper Erne catchment area.

Environmental and fisheries officers from the North-Western River Basin District were alerted to the incident by a call from a member of the public this past Tuesday (27 July).

And the State agency responsible for the protection and conservation of freshwater fish and habitats estimates that there could be in excess of 5,000 fish mortalities, including species such as bream, roach, perch and pike.

Fish samples have been taken from the lake and removed for further analysis. Initial investigations indicate that a severe algal bloom, combined with high water temperatures and low oxygen levels recorded in Barnagrow Lake, are the likely causes of the incident.

Dr Milton Matthews, director of the North-Western River Basin District with IFI, said: “Unfortunately, this is a very significant fish kill affecting several year classes of coarse fish and is the largest reported fish kill nationally to date in 2021.”

He added: “During the recent heatwave, very high water temperatures were noted at several angling locations, with temperatures of over 26 degrees [Celsius] for example recorded in Lough Sheelin, Co Cavan.

“In the days preceding the fish kill at Barnagrow Lake, a severe algal bloom was noted by Inland Fisheries Ireland staff, which together with very high water temperatures recorded locally, which were 22 degrees [Celsius], likely resulted in this serious fish kill event due to reduced oxygen levels in the water.”

Authorities in Northern Ireland are investigating a fish kill that’s claimed hundreds of trout in a stretch of the Three Mile Water in Co Antrim.

According to BBC News, many of the dead trout “were sizeable fish of spawning age”.

Officials at the Department of Agriculture, Environment and Rural Affairs (Daera) have not identified the origin of the alleged pollution incident.

It is also understood that water levels in the river have been low following the recent warm and dry weather spell. BBC News has more on the story HERE.

In other NI angling news, a Portadown man has been fined £1,000 after admitting a series of offences at the north lake in Craigavon, as ArmaghI reports.

At a recent sitting of Craigavon Magistrates’ Court, Gareth McLoughlin was convicted of fishing without a licence and permit, fishing on a closed fishery, obstruction and failing to provide his name and address to fisheries officers in an incident on 12 January 2020.

The court heard McLoughlin was observed angling with four rods at a lake which was at the time closed to angling, and fled the scene when challenged.

It could be years before a river at the centre of a recent suspected agricultural pollution incident in Co Tyrone is fully recovered, as the Belfast Telegraph reports.

The fish kill in the Aughlish River discovered over the May Bank Holiday weekend covered a five-mile stretch of the Northern Ireland waterway between Dromore and Fintona, with reports of thousands of dead brown trout and young salmon to the Loughs Agency.

Omagh Anglers secretary Terry Smithson said the incident was “devastating”. He estimated that five years of salmon stock had been lost and it could be as many as three years before the waterway recovers.

Northern Ireland’s Agriculture Minister has confirmed that a fish kill in a tributary of the River Moyola last week was caused by a spillage of 30,000 gallons of slurry, as BBC News reports.

The incident on the Grange River in Co Derry on Thursday 21 May affected a significant stretch of water near the village of Desertmartin, according to a local angling club.

It’s understood that the spillage originated from an over-ground slurry tank, but the circumstances are still being investigated.

The incident comes just weeks after anglers in Co Armagh expressed anger at the killing of more than 1,000 wild brown trout by pollution in the Glenavy River.

Anglers in Co Antrim have expressed their anger after more than 1,000 wild brown trout were killed in a pollution incident at the weekend.

As the Belfast Telegraph reports, members of the Glenavy Conservation and District Angling Club spotted a number of distressed fish gasping for air in the Glenavy River on Friday (8 May).

An initial count of some 500 dead fish was later doubled to over 1,000, linked to what the angling club suggests was a pollution incident close to the Gobranna Road in Glenavy.

“Hundreds, possibly thousands” of other, smaller fish such as stone loach were also “wiped out” in the fish kill, says club chairman Anthony McCormack.

It’s understood that hundreds if not thousands of fish including brown trout, juvenile salmon and bream may be affected by a fish kill on a tributary of the Bandon River in Co Cork.

Inland Fisheries Ireland (IFI) says it is investigating the fish kill on a minor tributary of the Bandon River in Co Cork in the stream south of Dunmanway near Curraghalicky Lake.

IFI says it attended the site on Monday evening (26 August) following a report from a local angler — and initial investigations point to “a significant algal bloom” as the cause.

“Efforts are ongoing to assess the extent of the fish kill and an aerial survey of the lake is underway,” IFI adds.

“Cork County Council has taken water samples from the lake and river and is liaising with Inland Fisheries Ireland in their investigation.”

Inland Fisheries Ireland (IFI) says it has confirmed a significant fish kill on the Royal Canal in Kilcock, Co Kildare earlier this week.

A report was received on Monday 1 July from Waterways Ireland of the fish kill, which has claimed some 300 fish of various species including roach, rudd, bream and pike.

The investigation, which commenced immediately and remains ongoing, has identified agricultural discharge to a River Ryewater feeder that enters the canal at Kilcock.

IFI says work is now ongoing to ensure that there is no further polluting discharge to the system from this location.

It has also has issued a fresh appeal to farmers to remain vigilant in avoiding water pollution during the summer months when harvesting silage and spreading slurry.

Silage effluent is a significant pollutant and if allowed to enter a waterway can potentially lead to fish death and habitat degradation.

IFI has a confidential hotline number at 1890 34 74 24 or 1890 FISH 24 for the public to report incidents of water pollution, fish kills and illegal fishing. For more visit fisheriesireland.ie.

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.
