State-owned forestry company Coillte and its contractor, Oliver Kelly Timber Harvesting Ltd, have both pleaded guilty to breaches of the Fisheries (Consolidation) Act 1959 in a case brought by Inland Fisheries Ireland (IFI).

Following reports of pollution in November 2021 along the Glenaboy River, a tributary of the Bride River in Co Cork, officers from IFI found heavy deposits of silt, vehicle tracks in the river bed and a lack of adequate silt control in an area where Oliver Kelly Timber Harvesting Ltd had been carrying out thinning operations on behalf of Coillte.

As a result, IFI estimated that significant damage had been done to spawning beds and that a valuable stretch of the river had been lost to spawning wild Atlantic salmon and sea trout that year.

Sitting before Judge Colm Roberts at Mallow District Court on Monday 28 November, Coillte pleaded guilty to a breach of Section 171 (1) of the Fisheries (Consolidation) Act 1959.

Also before the court on that date was Oliver Kelly Timber Harvesting Ltd, which Judge Roberts believed were the main instigators of the silt discharge to the Glenaboy River.

Judge Roberts afforded Coillte the benefit of the Probation of Offenders Act and ordered a payment of €2,000 to Tallow TidyTowns Committee.

Oliver Kelly Timber Harvesting Ltd were also found guilty of a breach of Section 171 as well as Section 173 of the 1959 Act and Section 3 of the Local Government (Water Pollution) (Amendment) Act 1977. The company was also given the benefit of the Probation Act and ordered to pay €2,000 to the Tallow Anglers Association, €1,500 to the Tallow TidyTowns Committee and post a bond of €1,500 for a period of two years under Section 1-1(2) of the Probation Act.

The court heard evidence that IFI officers, including senior fisheries environmental officer Andrew Gillespie, visited the location between Sunday 20 and Tuesday 22 November following reports of pollution.

There was evidence of silt in the river over a five-kilometre stretch downstream of the thinning operation’s location. Gillespie highlighted that the time of the occurrence, in November, was particularly relevant as it was the critical spawning period and that the effect of the silt discharge would be to smother any eggs deposited in the spawning gravels.

Speaking in court, Judge Roberts remarked that Coillte “didn’t properly supervise” the thinning operations and that their contractor “didn’t supervise properly as he was overstretched,” before observing that “when State agencies fail in their obligations, we are in big trouble”.

Sean Long, director of the South Western River Basin District at IFI welcomed the decision, noting that neither Coillte nor their contractor had been before the courts before and had cooperated fully with IFI to implement immediate mitigation measures at the site.

Speaking after verdict was delivered, Long said: “Located in the Munster Blackwater Special Area of Conservation, the Glenaboy River is a very important spawning ground for returning wild Atlantic salmon and sea trout, which are very vulnerable species protected by conservation measures and legislation.

“Sadly, the damage that was done to these spawning beds through pollution was significant, meaning that a valuable stretch of this river had been lost for spawning salmon and sea trout last year.”

Inland Fisheries Ireland (IFI) has launched a funding call of up to €1 million to support vital conservation projects around the country through the Salmon and Sea Trout Rehabilitation, Conservation and Protection Fund.

Since 2016, more than €6 million in grants have been awarded to over 280 projects throughout the country under various funding schemes operated by IFI.

From now until Friday 16 December, eligible angling clubs, fishery owners and other stakeholders are invited to express their interest in applying for funding to support fisheries conservation through IFI’s Habitats and Conservation Scheme.

Priority will be given to projects that focus on habitat rehabilitation and conservation, such as rehabilitating damaged river habitats, improving water quality and helping fish overcome physical barriers like weirs.

In similar schemes in 2022, a total of €1,123,000 in funding was approved for 35 habitats and conservation projects based in Cavan, Cork, Donegal, Dublin, Galway, Leitrim, Limerick, Louth, Mayo, Meath, Monaghan, Wexford, Westmeath and Wicklow.

Suzanne Campion, head of business development at IFI said that the scheme’s focus is on protecting and conserving fish species and their habitats for future generations.

“Since 2016, projects under the Habitats and Conservation Fund have delivered approximately 29km of in-stream maintenance works and 37 kilometres of habitat restoration works. As well as that, 83km of spawning and nursery habitats have been made more accessible to migratory fish species, through five fish passage projects,” she said.

“Under the Habitats and Conservation Scheme, which is made possible through fishing licence and permit income, groups can now apply for grants to fund projects and measures in 2023 to continue this vital environmental work.”

In addition to the €1 million in funding available through the Salmon and Sea Trout Rehabilitation, Conservation and Protection Fund, up to €50,000 is available through the Midlands Fisheries Fund.

An information guide about the funding call is available to download. As part of the two-step process, all applicants must firstly complete an ‘Expression of Interest’ application on Inland Fisheries Ireland’s online grant management portal before 5.30pm on Friday 16 December.

After expressions of interest have been completed, full applications that align to fund objectives can be submitted via the online grant management portal until 5.30pm on Friday 27 January 2023. Decisions on applications and grants will be announced by IFI in May 2023.

On a special climate-focused edition of RTÉ’s Prime Time this past week, the news programme put the plight of Ireland’s wild salmon stocks in the spotlight.

Reporter Oonagh Smyth visited the Dawros River in Connemara where salmon runs have allegedly shrunk from as many as 3,000 two decades ago to less than 900 today.

These figures lead to an even worse picture nation-wide, with data showing that only 150,000 wild salmon returned to their spawning grounds in 2019 — a decline of almost 80% on the more than 685,000 salmon recorded in 2000.

Various reasons are behind this alarming fall, with climate change chief among them — forcing salmon to migrate further to find colder waters, and interrupting the food webs that sustain the fish at sea and in our rivers.

But local factors have also been blamed, including the licensing of open-cage salmon aquaculture against which conservation groups and some arms of the State are united in their opposition due to the risks of sea lice infestations.

Inland Fisheries Ireland (IFI) has opened a new footbridge over the Owenea River near Glenties in Co Donegal.

In a welcome boost for angling access on the Owenea fishery, the new steel footbridge was commissioned by IFI to replace the former ‘Green Bridge’, which was constructed in the 1970s but had fallen into disrepair.

The new steel footbridge is now officially open to anglers and the public.

Funded through the National Strategy for Angling Development, the custom-designed footbridge will provide safe access to both banks of the Owenea fishery between Beats 4 and 5, near Glenties.

The Owenea fishery, which is directly managed by IFI, remains one of the most productive salmon rivers in Co Donegal.

The fishery has a good run of salmon and sea trout as well as a resident stock of small brown trout and is popular with local anglers as well as visiting sport fishers travelling from abroad.

Milton Matthews, director of the North-Western River Basin District with IFI, announced the opening of the bridge, saying: “The Owenea fishery in Donegal is a popular destination for both local and visitor salmon anglers to the area.

“Installation of this new bridge is the culmination of over four years of work in terms of completion of the various safety, engineering and associated environmental reports and planning permission requirements needed.

“Inland Fisheries Ireland would like to acknowledge the contribution and support of various local landowners, contractors, Donegal County Council, local angling clubs and dommunity development groups, who have all contributed to and welcomed the successful delivery of this project.”

IFI has an ongoing programme of maintenance and upgrading of angling access along the Owenea River, including the improvement of angling infrastructure such as stiles, footbridges and walkways.

Constructed in the 1970s, the Green Bridge was used extensively over the years by anglers, recreational walkers and local residents.

However, following safety audits conducted by IFI, consultant engineers were commissioned in 2021 to conduct a full examination of the structural integrity and suitability of the structure as a pedestrian footbridge. The report confirmed that the steelwork of the existing bridge was severely corroded and no longer fit for purpose.

Although IFI didn’t own or manage the Green Bridge, the State agency responsible for the conservation and protection of freshwater fish and habitats — and the development and promotion of angling — undertook responsibility for its removal and installation of a replacement galvanised footbridge to ensure safe access to both banks of the Owenea River for the angling community.

Before the old footbridge could be removed however, IFI had to commission several reports and surveys, including Appropriate Assessment Screening, a freshwater pearl mussel survey and Natura Impact Statement (NIS). Planning permission was then sought through Donegal County Council for removal and replacement of the old bridge.

Following a public procurement process, Source Civil Ltd was appointed as the contractor to remove the original Green Bridge and to prefabricate and install a new custom-designed footbridge from W.D. Buchanan & Co Ltd. This necessitated a temporary road closure and traffic diversion whilst the Green Bridge was removed and the new bridge was lifted into place by Quinn Crane Hire.  

Matthews added: “Completion of this new footbridge is a vital element in the overall management and development of the Owenea salmon fishery and a welcome addition for angling access and the local community.”

Salmon and sea trout anglers who fished during the 2022 season are being reminded to return their logbooks and any unused gill tags at the end of the season.

Inland Fisheries Ireland (IFI) is encouraging such anglers to return their angling logbooks — setting out their fishing and catch record — and any unused gill tags from 2022 if they have finished fishing for this year or once the season has closed.

Under the Wild Salmon and Sea Trout Tagging Scheme, anglers can return these in one of three ways:

  • Using the postage pre-paid business return envelope that was supplied at the time of licence purchase (preferred option).
  • Posting the logbook and unused gill tags to the Inland Fisheries Ireland office address that is displayed on their licence or logbook.
  • Scanning and emailing logbook and licence documents to IFI at [email protected]. Important: if you are choosing this option, please scan all sides of documents, including continuation pages, to ensure that the licence names and number can be correctly linked to the logbook.

On average, 70% of anglers in Ireland return their logbooks and these returns provide vital information regarding the status and management of our wild Atlantic Salmon and Sea Trout stocks into the future.

In accordance with the Wild Salmon and Sea Trout Tagging Scheme, anglers in Ireland are required by law to return their completed logbook and all unused tags to the issuing office of IFI within seven days of licence expiry, and no later than Wednesday 19 October.

As part of the scheme, an angler must attach a valid gill tag to a salmon (any size) or sea trout (over 40cm) harvested, immediately on landing. They must enter details of their catch and/or gill tag used into their logbook.

Questions or queries should be directed to [email protected] and IFI says it will respond as quickly as possible.

A research award targeted at early-career researchers has been granted to Dr Joshka Kaufmann of the Marine Institute to investigate and predict how quickly natural Atlantic salmon evolve to human-driven environmental change. The SFI-IRC Pathway programme, a new collaborative initiative between Science Foundation Ireland (SFI) and the Irish Research Council (IRC), has been awarded to Dr Kaufmann to conduct state-of-the-art research at the Marine Institute on the evolutionary potential of natural populations of Atlantic salmon in Ireland and develop an independent track record in this important climate-biodiversity research nexus.

As current rates of planetary stress are leading to unprecedented declines in natural populations, understanding the potential of iconic species such as the Atlantic salmon to adapt to human impacts has become crucial for their preservation and management.

Dr Ciaran Kelly, Director of Fisheries Ecosystems Advisory Services of the Marine Institute said, “In line with national, European and global priorities on climate and biodiversity, this research will identify vulnerabilities and ultimately offer strategies for optimal conservation; helping to balance sustainable aquaculture with the interactions between natural and aquaculture environments. In addition to strengthening Irish research capabilities, the project will contribute towards evidence-based policy-making at national and international level, providing advice through ICES (International Council for Exploration of the Seas) to NASCO (North Atlantic Salmon Conservation Organisation) and stakeholder groups such as the Atlantic Salmon Trust.”

The Marine Institute Newport research station in the Burrishoole catchment is a proven long-term natural observatory and an index Irish Atlantic salmon population. The systematic monitoring and sampling of salmon in the Burrishoole system (Co. Mayo) since 1958 provides a unique opportunity to link temporal changes in size, demography and genetic makeup of salmon with climate change, overfishing and mixing with cultured fish.

Prof. Philip McGinnity (UCC), Marine Institute Principal Investigator in Fish Population Genetics and lead on the SFI Investigators Award said,“Long-term ecological (and evolutionary) research is crucial to understanding how the world is changing and for informing conservation and protection programmes. Long-term studies with consistent data collection is rare, particularly in Ireland. As anadromous fish bridge freshwater and marine environments, they also provide an invaluable resource to understand the dynamic interconnections between land and sea and the role human actions such as climate change and overfishing.”

Dr Kaufmann of the Marine Institute said, “Building upon recent research successes constructing whole wild population pedigrees in SFI and Beaufort programmes, my plan is, with the support of a PhD student, to use next-generation high-throughput sequencing technologies and climate attribution to evaluate the evolutionary potential of natural populations of Atlantic salmon. Utilising these unique and irreplaceable multi-decadal pedigrees, I will identify how selection on traits changed with time and how this can impact the characteristics of salmon in the next decades.”

This knowledge will help provide advice for conservation and management of this iconic species under future climate scenarios and help reconcile the competing goals of aquaculture, fisheries and conservation. Dr Kaufmann will be hosted by the Marine Institute, Ireland's national agency for marine research and development, and work closely with other national and international research funders to promote the value of Ireland's unique marine resource.

This project is one of 53 research projects funded by the SFI-IRC Pathway programme to support early career research across all disciplines and to encourage interdisciplinary approaches.

The deadline to enter the third online lottery for ‘brown tags’ for wild salmon angling on the Lower River Lee is 5pm on Thursday 9 June.

A further 38 brown tags will be issued on Monday 13 June by Inland Fisheries Ireland (IFI), following the second lottery for 38 tags on 11 April, as previously reported on Afloat.ie.

Under brown tag regulations, an angler who wishes to ‘harvest’ a wild salmon and keep it must attach a brown tag as well as a standard blue tag to the fish.

To help conserve stocks of wild salmon within the Lower River Lee, No 5 or Cork District, a total of 152 brown tags are available for the season and have been distributed to anglers with a 2022 rod licence through a series of online lotteries since January.

Anglers interested in entering the third draw are being asked to apply online between now and 5pm on Thursday 9 June. Only one entry is permitted per licence holder into the draw. Entries will not be accepted by email in this draw.

Anglers with a 2022 rod licence who are not allocated a brown tag are only permitted to fish for salmon on a ‘catch and release’ basis on the Lower River Lee, where the salmon is returned safely to the same waterbody.

In addition, anglers who received a tag in either of the previous draws may enter this draw only if they have used that tag. Anglers must be able to provide evidence of using the tag by supplying a photo of the double tagged salmon and the relevant entry in their angler’s logbook.

Further details and conditions are available from the IFI website, by phoning its Macroom office on (026) 41221 or emailing [email protected].

Farmed salmon is Britain’s largest food export by value – more valuable than anything else except beer.

Sounds impressive, but nutritious wild fish caught to sustain salmon farming is being squandered a new study maintains.

Scientists analysing the Scottish salmon farming industry calculate that an extra six million tonnes of seafood would be available annually if wild caught fish is diverted away from aquaculture feed.

The new study, as Afloat reported previously here published in the research journal PLOS Sustainability and Transformation says that limiting salmon farming to using feed made from fish by-products could result in 3.7 million tonnes of fish being left in the sea.

Dr Karen Luyckx of the Feedback ngo, which welcomed the findings, said that “until the salmon industry kicks its wild-caught fish oil and fishmeal habit, chefs and retailers should help citizens switch away from unsustainable salmon by offering ultra-nutritious mussels and small oily fish instead.”

Study author Dr David Willer, research fellow at the University of Cambridge, spoke to Wavelengths this week about the study and the reaction from industry.

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.
