#angling – Inland Fisheries Ireland (IFI) is today continuing to monitor an incident of pollution on the River Loobagh in Limerick, which resulted in an extensive fish kill earlier this week.

On 4th August 2014, IFI received a report from local anglers in Kilmallock that the River Loobagh at Riversfield Bridge, near the Limerick County Council water treatment plant, was in a polluted condition and dead fish could be seen. The River Loobagh is an important fishery, primarily for brown trout, but also for salmon which seemed to be returning to the river in small numbers.

A discharge of effluent into the River Loobagh was located, and the source was traced to an over ground steel slurry tank on a nearby farm. Once IFI contacted the farm owner, works immediately proceeded to prevent further discharge and the flow of effluent was intercepted at a number of locations, effectively preventing further discharge.

A series of samples were taken which have been sent for analysis. Pending the results of the analysis a decision will be made by IFI concerning a prosecution and any other legal actions that may be warranted.

IFI staff carried out a visual inspection of the River Loobagh to determine the extent of the fish kill. Further to this, approximately 555 fish were observed to be dead, with an additional 95 fish found by the local angling club. The majority of the fish were brown trout, as well as a small number of juvenile salmon.

IFI is continuing to work with both the farmer and Limerick County Council to ensure that no further pollution can arise and that all appropriate remedial action is taken. IFI will continue to monitor the situation and ensure that any pollution risk is removed.

Inland Fisheries Ireland (IFI) has a confidential hotline number to enable members of the general public to report incidents - 1890 34 74 24 or 1890 FISH 24. This phone line is designed to encourage the reporting of incidents of illegal fishing, water pollution and invasive species.

#fishkill – Inland Fisheries Ireland and Dublin City Council are today (23.07.14) continuing to monitor the River Tolka following a significant pollution incident which occurred yesterday, Tuesday 22nd July.

A definite line of inquiry is being followed in relation to the source of the pollution incident which resulted in an extensive fish kill in the river.

Further samples have been taken and analysis is ongoing.

Dublin City Council has also removed a boom wall barrier which it erected across the River Tolka at Griffith Park yesterday to contain the pollutant as this is no longer required.

#FishKill - Inland Fisheries Ireland (IFI) received reports of a fish kill on the River Lear in Baileborough, Co Cavan last Friday 23 May.

IFI staff responded immediately to the report and their investigations revealed approximately 35 dead brown trout and roach on this tributary of Castle Lake.

The kill extended over 2km, from just upstream of Lear Bridge (on the Baileborough to Shercock Road) as far as Castle Lake.

Water samples were taken from a number of locations along the affected stretch and IFI are awaiting results. Subsequent reports of dead fish in Castle Lake have been received by IFI.

Cavan County Council, who was informed of the fish kill by IFI, has launched its own separate investigation. IFI has also informed the Environmental Protection Agency (EPA).

During the course of their investigations, IFI staff also found a number of dead trout in a field adjoining the River Lear and a separate investigation has commenced to establish to how these fish came to be at this location.

IFI is particularly concerned about these incidents on the River Lear as there have been a number of fish kills here in the past, especially during low flow and high temperature events.

#FishKill - A Carlow farmer has pleaded guilty to the accidental discharge of 'deleterious matter' into the River Burren at Cloontoose on 10 June last year, resulting in a fish kill that cost as many as 5,000 brown trout.

At a sitting of the District Court at Carlow Court House on Thursday 2 January, Judge O’Brien awarded costs of €2,135 to Inland Fisheries Ireland (IFI) and ordered that the farmer pay a contribution for habitat works.

The incident related to the release of fungicide to the river during the filling a a crop sprayer.

Donnachadh Byrne, senior fisheries environmental officer with IFI, told Judge O’Brien that following receipt of a fish kill report from Carlow County Council on Monday 10 June, IFI carried out investigations on the River Burren and had established that the fish kill extended over 4.2km with an estimate of 4,000-5,000 dead brown trout.

Giving details of sampling and analysis undertaken, Byrne confirmed that samples of dead fish taken from the Burren River when sent for analysis were found to have elevated concentrations of Pyraclostrobin, one of the main active ingredients of the fungicide Lumen, used to treat barley or oats, which was being used by the defendant.

The court was informed that the spillage of fungicides to the Burren River was accidental and related to a non-return valve which upon later inspection was found to be faulty,

These facts were acknowledged by IFI, who also confirmed that the defendant was fully co-operative at all times during the investigation.

The Burren River fish kill which extended over 4.2 kilometres, related to a relatively small discharge of pesticide to the Burren River.

IFI said the incident highlights the extreme toxicity of certain pesticides to the aquatic environment, as what was a relatively small discharge of pesticide extended to a stretch of more than 4.2km of the watercourse.

#FishKill - Inland Fisheries Ireland has secured a successful prosecution of a Galway-based construction company over a fish kill on the River Dodder in South Dublin earlier this year.

Ward and Burke Construction Ltd of Stradbally East, Kilcolgan, Co Galway was convicted and fined €2,000 by Judge William Hamill at a sitting of the District Court at the Four Courts on Monday 14 October.

The judge found in favour of Inland Fisheries Ireland (IFI) who took the prosecution following its investigation into the fish kill, which saw some 500 freshwater fish - including juvenile brown trout, lamprey and stoneloach - deceased over a 2km stretch of the River Dodder in the Tallaght area from below an outfall from Boherboy Water Supply Pipeline to a point upstream of Firhouse Weir.

Giving details of the sampling and analysis undertaken, IFI fisheries environmental officer Brian Beckett confirmed the discharge from the water supply pipeline to the Dodder was characterised by seriously elevated levels of chlorine.

Beckett said that on the afternoon of 1 March 2013, he instructed staff from Ward and Burke Construction Ltd to immediately terminate the discharge, and prevent all remaining effluent residues from entering the watercourse. Ward and Burke staff were found to be fully co-operative at all times during the investigation.

Legal representatives for Ward and Burke who had earlier told Judge Hamill there was a plea in the matter said that the discharge occurred as a result of human error, and as soon as this had come to their attention they had taken steps to prevent any further discharge.

It was also submitted that the construction firm had committed to provision of a sum of money to cover restocking or other appropriate costs to mitigate against damage caused as a result of the discharge.

Judge Hamill convicted Ward and Burke Construction Ltd and imposed a fine of €2000 and awarded legal costs and expenses to Inland Fisheries Ireland.

#FishKill - Staff with Inland Fisheries Ireland (IFI) are investigating two separate fish kill incidents on Lough Keeldra in Co Leitrim and in the Camlin River in Longford town.

Considerable numbers of dead perch were recorded at Lough Keeldra, outside Mohill, following a report to IFI on 10 September. Live fish also observed in the lake were noted to be in distress.

The presence of blue/green algae is currently being considered as part of the investigations. Lough Keeldra is a designated bathing area and signs erected by Leitrim County Council prohibit bathing at present.

Elsewhere, more than 2,000 fish mortalities were recorded over a 6km stretch of the Camlin River from Cartron Bridge downstream as far as the confluence with the River Shannon after IFI staff began their investigation on 4 September following a tip-off from the public.

Brown trout, roach, pike, eel and white-clawed crayfish were among the dead fish discovered, although live fish have since been recorded within the affected area.

Water samples have been taken for analysis and IFI continuing with its investigation to try to identify the source of the pollution that caused the fish kill. This may not be possible given the fact that the fish kill is believed to have occurred on the weekend of the 1 September.

Members of the public are being urged to note that after a prolonged period of low flow levels and unseasonably high water temperatures, all aquatic life - but especially fish - are extremely vulnerable to the slightest deterioration in water quality.

Landowners and the owners of any premises or property that adjoins a watercourse should take particular care to ensure that every reasonable measure is taken to minimise any threat to water quality and fish life.

IFI is appealing to the public to report any incident or suspected incident of pollution or deterioration of water quality and sightings of distressed fish.

Amanda Mooney, director for the Shannon River Basin District, said: “Whether an incident occurs deliberately or inadvertently, it is critical for fish welfare and general water quality that incidents can be dealt with promptly.”

Inland Fisheries Ireland operates a confidential 24 hour hotline and suspected illegal fishing or pollution can be reported to 1890 347 424.

#Angling - Inland Fisheries Ireland (IFI) is seeking the help of anglers and the general public to report any sightings of distressed fish due to high water temperatures or low water levels. 

The national fisheries body also requests that anglers voluntarily cease using keep nets during this period, so as not to cause unintentional distress to fish kept for long periods in these nets.

Reports may be made to the local fisheries offices or the 24-hour hotline number on 1890 34 74 24. 

IFI staff will continue to monitor canals, lakes and rivers for any signs of distressed fish in shallow water, but may be able to react more quickly to timely reports received.

"Low water levels and high water temperatures may lead to fish kills," said IFI chief Dr Ciaran Byrne, "and as the temperatures for salmon and trout are perilously hot at the moment, fish kills may be unavoidable. In many instances, moving fish may also prove too stressful. 

"Anglers practicing catch and release during this hot spell may wish to consider desisting from fishing until conditions are more favourable."

Minister Fergus O'Dowd also urged anglers and the public to "please be vigilant and help conserve our wonderful inland fisheries resource".

#Angling - The World Youth Fly Fishing Championship is coming to Ireland's border region next month.

And as the Carrick Times reports, Carrickfergus in Co Antrim is looking forward to hosting part of the event at the Woodford Fly Fishery.

What's more, local lad and Woodford member Darren Crawford will be among the all-Ireland fly fishing squad vying for the international title at the event, co-sponsored by the Loughs Agency and Inland Fisheries Ireland.

Rivers and lakes hosting the competition are spread over the counties of Antrim, Louth, Monaghan, Meath and Tyrone.

In other inland fisheries news, Galway Bay FM reports that testing carried out after a fish kill in Loughrea Lake last month found no evidence of any bacterial or viral outbreak.

The cause of the incident that killed 100 perch in the lake are still unclear, though stresses connected with the spawning season are a distinct possibility.

#FishKill - Galway Bay FM reports on an investigation into a fish kill discovered in Loughrea Lake yesterday 12 May.

Inland Fisheries Ireland staff have attended the scene after being alerted by the public, discovering some 100 dead perch in the water.

However, it is believed the fish died as a result of a natural phenomenon, as no dead fish of any other species was found.

Such mortalities in the wake of the perch spawning season are not uncommon due to the stresses it puts on the fish, leaving them susceptible to infection.

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.
