Legislation approved by Minister for Environment Eamon Ryan will allow for 81 rivers to be accessible for salmon and sea trout angling next year.

Of the 81, 42 will be open, with a further 39 open to “catch and release” angling, he said, noting the “general improvements in stocks from 2023 have been maintained for 2024”.

However, 66 rivers are to be closed as they have no sustainable surplus available, a point highlighted recently by an Afloat reader in County Cork.

The legislation is based on management advice from Inland Fisheries Ireland (IFI) for over 140 genetically individual wild salmon stocks in Ireland, which was based on individual scientific assessments.

The minister said the assessments are carried out every year by the Technical Expert Group on Salmon (TEGOS) – an all-island independent scientific group comprising experts from a range of bodies.

“Many of our rivers are not at a sufficiently high-water quality level to support sustainable stocks, often caused by agricultural activities, and to a lesser extent, insufficient treatment of waste water,” he said.

“ This year’s advice was also made available as part of a statutory public consultation process during which written submissions from stakeholders (including the recreational and commercial fishing and the environmental sectors) were sought on the draft regulations,” he said.

“Ireland has long been internationally recognised for embedding the conservation imperative as a vital component of our management of the precious salmon resource,” Ryan said.

“ While the policy has served us well for more than a decade, I intend, as part of a broader inland fisheries policy review, to set out options for improvement, with an even greater focus on conservation, in our management regime and for modernising licensing requirements, to ensure access to the resource where its conservation and biodiversity needs are met,” he said.

A sea trout tagged as part of a collaborative project led by the Loughs Agency and the River Faughan Anglers has provided remarkable insights into the growth and behaviour of these elusive fish within the Lough Foyle system.

The ‘Casting for Knowledge’ initiative highlights the value of combining the expertise of local anglers and scientific researchers to unravel the mysteries of sea trout ecology.

The sea trout in question, which bore the tag number 7841, was implanted on 12 May 2022 in the Faughan River thanks to the generous support of the River Faughan Anglers, who purchased the tag. The fish was then caught by a member of the club in the lower reaches of the river on 3 July this year.

This sea trout exhibited a unique pattern of behaviour by never venturing out to sea, and instead remaining exclusively within the Lough Foyle system.

In addition, the tagged sea trout demonstrated an impressive growth rate during this period, gaining 620 grams over the course of 14 months.

The Loughs Agency has championed the discovery as “a testament to the successful collaborative working between scientific researchers and angling clubs of the Faughan, Roe and Carrickmore rivers”.

Dr Diego del Villar, senior scientific officer at the Loughs Agency and lead scientist on the Casting for Knowledge project, expressed excitement about these significant findings.

“The journey of this sea trout showcases the immense potential of collaboration between anglers and scientists,” he said. “By harnessing the knowledge and expertise of local angling clubs, we can unlock crucial insights that have far-reaching implications for the management and conservation of these remarkable fish.”

Gerry Quinn, secretary at River Faughan Anglers added: “Having sponsored several tags, we were really interested to learn that a sea trout which was tagged on 12 May last year had successfully negotiated the various perils of the Faughan’s tidal stretch and Lough Foyle, and returned to the river just short of 14 months later. Indeed, the fact it was caught a few hundred yards from where it was tagged was quite the surprise.

“As fishers of the Faughan’s sea-going trout and custodians of the river, we welcome the opportunity to participate in and sponsor programmes which help to inform us about the lives of these elusive children of the tides.”

Inland Fisheries Ireland (IFI) has announced the 24 projects awarded a total of €999,272 from the Salmon and Sea Trout Rehabilitation, Conservation and Protection Fund.

The competitive fund, administered by IFI, supports sustainable development initiatives to ensure native salmon and sea trout can survive and thrive, and overcome challenges they face in the wild.

The transformative new fish conservation projects in 12 different counties include:

  • Riverside fencing and solar pasture drinking pumps in Co Offaly to minimise pollution by livestock encroachment in water.
  • A major fish barrier removal scheme in Co Wicklow to help improve river connectivity for migratory fish and eel.
  • A project to curb the spread of the invasive plant species, rhododendron, on river catchments in Co Mayo to benefit in-stream habitat quality.
  • Spawning enhancement and habitat restoration works in the River Boyne catchment in Co Meath.
  • Surveillance measures, using environmental DNA, to monitor the presence of invasive pink salmon species in Irish rivers nationwide.

Announcing the projects on Friday (26 May), Minister for the Environment, Climate and Communications, Eamon Ryan said: “I welcome the nearly €1m in funding which IFI is investing in projects across Ireland to improve and protect our incredibly important freshwater fish and their habitats.

“Our rivers are like the nature and biodiversity arteries of the country. Since the 1980s we have seen a significant deterioration in their water quality, putting our freshwater fish and their habitats under considerable stress.

“It is crucial to protect and future-proof our natural resources and this funding helps to do that. It is particularly encouraging to see applicants to the scheme taking on the stewardship over their local natural amenities.”

The Salmon and Sea Trout Rehabilitation, Conservation and Protection Fund has provided over €3.75m to different groups and fisheries development experts since 2016.

Barry Fox, head of operations with IFI said: “The Salmon and Sea Trout Rehabilitation, Conservation and Protection Fund is made possible through fishing licence income. Conserving and protecting fish species, like Atlantic salmon and sea trout is an integral part of IFI’s progressive and sustainable salmon management operations.”

Grants will be provided to initiatives based in Offaly (€80.5k), Cork (€140k), Donegal (€3.5k), Galway (€78k), Clare (€42.7k), Kerry (€18k), Kildare (€6.3k), Sligo (€34.3k), Mayo (€124k), Meath (€104.2k), Wicklow (€115k), Westmeath (€73k), and national projects (€180k).

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.”

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.

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.

The Loughs Agency reminds anglers of the annual close season, which prohibits angling over the winter months to help protect salmon and sea trout from disturbance when spawning.

The Foyle Area and Carlingford Area (Close Seasons for Angling) Regulations prohibit fishing for salmon and sea trout over the winter, with fishing due to resume in early 2022.

The annual close season for salmon and sea trout began last Thursday 21 October in the Foyle catchment, and starts Monday 1 November in the Carlingford catchment.

As closing dates vary slightly across the catchments, Loughs Agency encourages anglers to check season dates for each river on the Loughs Agency website and social media platforms, as well as with fishery owners to ensure they are up to date on local restrictions.

The State of the Salmon report published recently by the international lead on salmon management, the North Atlantic Salmon Conservation Organization (NASCO), highlights the worrying and continuous decline in the populations of the Atlantic salmon.

NASCO states: “It now takes about double the number of eggs to produce one adult (compared to 1990s) that will return to that same river to spawn – an indication of the multiple pressures facing the species throughout its complex life cycle.”

Lough Agency chief executive Sharon McMahon said: “The annual close season is an important time of year. Reducing disturbances on fish when they are spawning and at their most vulnerable helps protect stocks for the future.

“We recognise that angling is not the sole cause of stock decline, but by observing the close season, anglers are ‘playing their part’ in boosting the long-term resilience and sustainability of iconic fish species.”

John McCartney, director of conservation and protection at the Loughs Agency, added: “We all must take a forward-thinking approach based on the latest scientific guidance that balances responsible angling and sustainability.”

As the game fishing season ends for 2021, anglers are reminded to update their catch return and fishing effort on the Loughs Agency elicence website.

Anglers who wish to fish during the winter months are permitted to catch coarse fish such as perch, roach and bream, for which a valid coarse fishing licence is required.

During the close season, Loughs Agency fishery officers patrol riverbanks to prevent illegal fishing and protect fisheries. Anglers found fishing out of season will be prosecuted through the courts.

The Loughs Agency encourages members of the public to make direct and prompt illegal fishing reports either through the 24-hour response line at +44 28 7134 2100 or through the WaterWatch reporting tool.

Inland Fisheries Ireland (IFI) has launched a public consultation on the future management of the Wild Salmon and Sea Trout Tagging Scheme.

The State agency with responsibility for the protection and conservation of freshwater fish and habitats is encouraging anyone with an interest in the area to submit their views on how the tagging system, which started in 2001, can be improved and modernised.

It is especially keen to hear from salmon and sea trout anglers, angling clubs, commercial fishermen and those businesses that distribute salmon and sea trout licences, such as fishing tackle shops.

The Wild Salmon and Sea Trout Tagging Scheme was set up 20 years ago to record the issuing of wild salmon and sea trout licences, gill tags and logbooks to both recreational anglers and commercial fishermen and to process details of fish catches on a database for further analysis.

It was part of a series of measures introduced to help with the management and conservation of Ireland’s wild salmon and sea trout populations, which have been in decline.

Figures from the 2020 Wild Salmon and Sea Trout Statistics Report show that 14,138 salmon and sea trout licences were sold to recreational anglers in the state last year, which were a mixture of virtual licences sold online and hard copy licences sold over the counter in shops. In addition, 78 public commercial licences were made available to commercial fishermen in 2020.

IFI is now carrying out a review of the whole tagging system, to see how it can be made more user-friendly in the future and to ensure that it can provide the agency with real-time, accurate data to assist with the protection, management and conservation of wild salmon and sea trout.

Suzanne Campion, IFI’s head of business development, said:“The Wild Salmon and Sea Trout Tagging Scheme was first introduced two decades ago and since then, we’ve seen a seismic shift towards buying and selling online, with many technological advances along the way that we’d like to harness.

“As we’re undertaking a review of the tagging system, we see this as the perfect opportunity for the public, especially those involved in the angling sector, to have their say on the management of how licences, tags and logbooks are issued and distributed in the future. In other words, how can Inland Fisheries Ireland make the tagging system as user-friendly as possible in the future and a better service for all?”

The public consultation for the Wild Salmon and Sea Trout Tagging Scheme closes at 5pm on Wednesday 1 December. Submissions can be made via a short online survey.

Alternatively, written submissions can be emailed to [email protected] or posted to Wild Salmon & Sea Trout Tagging Scheme Consultation, Inland Fisheries Ireland, 3044 Lake Drive, Citywest Business Campus, Dublin 24, D24 CK66.

For all you need on the Marine Environment - covering the latest news and updates on marine science and wildlife, weather and climate, power from the sea and Ireland's coastal regions and communities - the place to be is Afloat.ie.

Coastal Notes

The Coastal Notes category covers a broad range of stories, events and developments that have an impact on Ireland's coastal regions and communities, whose lives and livelihoods are directly linked with the sea and Ireland's coastal waters.

Topics covered in Coastal Notes can be as varied as the rare finding of sea-life creatures, an historic shipwreck with secrets to tell, or even a trawler's net caught hauling much more than just fish.

Other angles focusing the attention of Coastal Notes are Ireland's maritime museums, which are of national importance to maintaining access and knowledge of our nautical heritage, and those who harvest the sea using small boats based in harbours where infrastructure and safety pose an issue, plying their trade along the rugged wild western seaboard.

Coastal Notes tells the stories that are arguably as varied as the environment they come from, and which shape people's interaction with the natural world and our relationship with the sea.

Marine Wildlife

One of the greatest memories of any day spent boating around the Irish coast is an encounter with Marine Wildlife. It's a thrill for young and old to witness seabirds, seals, dolphins and whales right there in their own habitat. And as boaters fortunate enough to have experienced it will testify, even spotting a distant dorsal fin can be the highlight of any day afloat. Was that a porpoise? Was it a whale? No matter how brief the glimpse, it's a privilege to share the seas with Irish marine wildlife.

Thanks to our location in the North Atlantic, there appears to be no shortage of marine life to observe. From whales to dolphins, seals, sharks and other ocean animals, the Marine Wildlife category documents the most interesting accounts around our shores. And we're keen to receive your observations, your photos, links and video clips, too!

Also valuable is the unique perspective of all those who go afloat, from coastal sailing to sea angling to inshore kayaking to offshore yacht racing, as what they encounter can be of great importance to organisations such as the Irish Whale and Dolphin Group (IWDG). Thanks to their work we now know we share the seas with dozens of species who also call Ireland home. But as impressive as the list is, the experts believe there are still gaps in our knowledge. Next time you are out on the ocean waves, keep a sharp look out!

Weather

As an island in the North Atlantic, Ireland's fate is decided by Weather more so than many other European countries. When storm-force winds race across the Irish Sea, ferry and shipping services are cut off, disrupting our economy. When swollen waves crash on our shores, communities are flooded and fishermen brace for impact - both to their vessels and to their livelihoods.

Keeping abreast of the weather, therefore, is as important to leisure cruisers and fishing crews alike - for whom a small craft warning can mean the difference between life and death - as it is to the communities lining the coast, where timely weather alerts can help protect homes and lives.

Weather affects us all, and Afloat.ie will keep you informed on the hows and the whys.

Marine Science

Perhaps it's the work of the Irish research vessels RV Celtic Explorer and RV Celtic Voyager out in the Atlantic Ocean that best highlights the essential nature of Marine Science for the future growth of Ireland's emerging 'blue economy'.

From marine research to development and sustainable management, Ireland is developing a strong and well-deserved reputation as an emerging centre of excellence. Whether it's Wavebob ocean energy technology to aquaculture to weather buoys and oil exploration, the Marine Science category documents the work of Irish marine scientists and researchers and how they have secured prominent roles in many European and international marine science bodies.

Power From The Sea

The message from the experts is clear: offshore wind and wave energy is the future. And as Ireland looks towards the potential of the renewable energy sector, generating Power From The Sea will become a greater priority in the State's 'blue growth' strategy.

Developments and activities in existing and planned projects in the pipeline from the wind and wave renewables sector, and those of the energy exploration industry, point to the future of energy requirements for the whole world, not just in Ireland. And that's not to mention the supplementary industries that sea power projects can support in coastal communities.

Irish ports are already in a good position to capitalise on investments in offshore renewable energy services. And Power From The Sea can even be good for marine wildlife if done properly.

Aside from the green sector, our coastal waters also hold a wealth of oil and gas resources that numerous prospectors are hoping to exploit, even if people in coastal and island areas are as yet unsure of the potential benefits or pitfalls for their communities.

Changing Ocean Climate

Our ocean and climate are inextricably linked - the ocean plays a crucial role in the global climate system in a number of ways. These include absorbing excess heat from the atmosphere and absorbing 30 per cent of the carbon dioxide added to the atmosphere by human activity. But our marine ecosystems are coming under increasing pressure due to climate change.

The Marine Institute, with its national and international partners, works to observe and understand how our ocean is changing and analyses, models and projects the impacts of our changing oceans. Advice and forecasting projections of our changing oceans and climate are essential to create effective policies and management decisions to safeguard our ocean.

Dr Paul Connolly, CEO of the Marine Institute, said, “Our ocean is fundamental to life on earth and affects so many facets of our everyday activities. One of the greatest challenges we face as a society is that of our changing climate. The strong international collaborations that the Marine Institute has built up over decades facilitates a shared focusing on our changing ocean climate and developing new and enhanced ways of monitoring it and tracking changes over time.

“Our knowledge and services help us to observe these patterns of change and identify the steps to safeguard our marine ecosystems for future generations.”

The Marine Institute’s annual ocean climate research survey, which has been running since 2004, facilitates long term monitoring of the deep water environment to the west of Ireland. This repeat survey, which takes place on board RV Celtic Explorer, enables scientists to establish baseline oceanic conditions in Irish waters that can be used as a benchmark for future changes.

Scientists collect data on temperature, salinity, water currents, oxygen and carbon dioxide in the Atlantic Ocean. This high quality oceanographic data contributes to the Atlantic Ocean Observing System. Physical oceanographic data from the survey is submitted to the International Council for the Exploration of the Seas (ICES) and, in addition, the survey contributes to national research such as the VOCAB ocean acidification and biogeochemistry project, the ‘Clean Atlantic’ project on marine litter and the A4 marine climate change project.

Dr Caroline Cusack, who co-ordinates scientific activities on board the RV Celtic Explorer for the annual survey, said, “The generation of long-term series to monitor ocean climate is vital to allow us understand the likely impact of future changes in ocean climate on ecosystems and other marine resources.”

Other activities during the survey in 2019 included the deployment of oceanographic gliders, two Argo floats (Ireland’s contribution to EuroArgo) and four surface drifters (Interreg Atlantic Area Clean Atlantic project). The new Argo floats have the capacity to measure dissolved ocean and biogeochemical parameters from the ocean surface down to a depth of 2,000 metres continuously for up to four years, providing important information as to the health of our oceans.

During the 2019 survey, the RV Celtic Explorer retrieved a string of oceanographic sensors from the deep ocean at an adjacent subsurface moored station and deployed a replacement M6 weather buoy, as part of the Irish Marine Data Buoy Observation Network (IMDBON).

Funded by the Department of Agriculture, Food and the Marine, the IMDBON is managed by the Marine Institute in collaboration with Met Éireann and is designed to improve weather forecasts and safety at sea around Ireland. The data buoys have instruments which collect weather and ocean data including wind speed and direction, pressure, air and sea surface temperature and wave statistics. This data provides vital information for weather forecasts, shipping bulletins, gale and swell warnings as well as data for general public information and research.

“It is only in the last 20 years, meteorologists and climatologists have really began to understood the pivotal role the ocean plays in determining our climate and weather,” said Evelyn Cusack, Head of Forecasting at Met Éireann. “The real-time information provided by the Irish data buoy network is particularly important for our mariners and rescue services. The M6 data buoy in the Atlantic provides vital information on swell waves generated by Atlantic storms. Even though the weather and winds may be calm around our shores, there could be some very high swells coming in from Atlantic storms.”
