Campaigners against salmon farms have raised concerns over the state of Irish wrasse stocks after it was confirmed the fish have been taken en masse to help clean lice from farmed salmon.

As Donegal News reports, a number of salmon farms in Donegal, Galway and other areas owned by Mowi — the former Marine Harvest — have between them moved in tonnes of wild wrasse, a known ‘cleaner fish’ that feeds on sea lice, over the past four years.

Responding to a Dáil debate question from Catherine Connolly TD this past summer, Marine Minister Michael Creed confirmed that “several special of cleaner fish are used in Ireland as a method of controlling sea lice”.

But there are fears that the mass withdrawal of wrasse and other such species from the wild could tip the balance of Ireland’s delicate marine ecosystem.

“The absence of wild wrasse in bays may result in stress and disease in other large species of fish which rely on wrasse to keep them clean of parasites,” said Billy Smyth, chair of Galway Bay Against Salmon Cages.

Collective work between scientists and the angling community for the survival of salmon in the cross-border catchments of Foyle and Carlingford was to the fore at the recent conference in Omagh hosted by the Loughs Agency.

Stark warnings over the decline of the species were heard along with presentations from the likes of Dr Diego Del Villar, who discussed the new SeaMonitor project that is currently studying the seas around Ireland, Northern Ireland and western Scotland, and will in time help produce a salmon management plan for the River Foyle.

The Loughs Agency says it will soon launch a public consultation to gauge the views of the public in managing the salmon fishery.

John McCartney, Loughs Agency director of conservation and protection, said: “We value the input and opinion of the public when reviewing our salmon management programme. I would encourage everyone take time to consider and respond to the questions.”

A small number of salmon are returning to Irish rivers with signs of bleeding and skin ulceration, according to Inland Fisheries Ireland. This follows reports of salmon also returning to Norway and Scotland with a red rash skin disease in recent months. Anglers and fishery owners are asked to report incidences of salmon with rash like symptom to Inland Fisheries Ireland to help determine the scale of the problem nationally.

Salmon first began appearing in Irish rivers with these symptoms in early June and by mid-June, there were reports of fish with ulceration in at least six rivers, both on the east and west coast of Ireland. The salmon who are affected show signs of bleeding, ulceration and haemorrhaging mainly along the area on the belly of the fish and on the head and the tail. Secondary fungal infection normally sets in and may result in death of the salmon.  

"Inland Fisheries Ireland appeals to anglers and fishery owners to report incidences of affected salmon"

Inland Fisheries Ireland is working with the Fish Health Unit in the Marine Institute to sample live salmon in affected rivers to determine the cause of the skin disease. Until the cause of the disease has been determined and the risk of spreading the disease established, affected salmon should not be removed from the water. Any anglers who capture salmon with these symptoms are advised to follow normal biosecurity procedures and disinfect tackle, waders and equipment. 

Dr Paddy Gargan, Senior Research Officer at Inland Fisheries Ireland said: “It is unclear at this time what is causing these symptoms. There is some evidence that the disease may become less frequent with rising water temperatures and the problem has been worst in multi-sea-winter fish entering rivers early in the year in Norway and Sweden. There is also a suggestion that the disease is related to a change in salmon diet but this has not yet been established. We are asking anglers and fishery owners to report any catches of salmon with these symptoms to us as soon as possible”.

Sean Canney, Minister of State with responsibility for the inland fisheries resource, visited the River Erriff in Co Mayo recently to understand more about the current issues facing Ireland’s salmon.

Inland Fisheries Ireland (IFI) has designated the River Erriff, one of Ireland's premier salmon and sea trout fisheries, as the National Salmonid Index Catchment.

Salmon and sea trout migrating upstream in the Erriff must pass through fish counting and trapping facilities located at Aasleagh Falls, where the Erriff flows into Killary Harbour.

Since 1985, salmon and sea trout smolts and kelts migrating downstream pass through a trap located below Tawnyard Lough.

The facilities at this research station are used for a wide range of scientific research and monitoring activities on the salmonid populations and their migratory behaviour.

Minister Canney met with Dr Ciaran Byrne, CEO of Inland Fisheries Ireland, who outlined that fisheries managers and scientists have been concerned for a number of years about the declining numbers of salmon returning to the Irish coast — a key concern in this International Year of the Salmon.

In the mid-1970s, almost 1.7 million salmon were estimated to have returned to Ireland, compared to only some 250,000 today.

Salmon are a key indicator species and they tell us so much about the health of our aquatic environment, IFI says.

And the issue is not unique to Ireland, as populations over the entire southern part of the North East Atlantic — which includes France, Spain, England, Scotland and southern Iceland — have declined significantly in the past number of decades.

Following the visit, Minister Canney commented: “Salmon are an iconic fish species in Ireland. They have always had a special place in Irish culture, heritage and mythology with stories such as the ‘Salmon of Knowledge’ familiar to generations of our school children.

“While they are widely distributed throughout Irish river systems, with over 140 designated salmon rivers, the numbers of salmon returning to Irish rivers, in common with salmon rivers internationally, have shown a worrying decline in recent decades.

“Today they remain an important resource to many people, playing an invaluable ecological, social and cultural role in Ireland and across the Northern Hemisphere.

“International Year of the Salmon offers us an opportunity to start an important conversation around how we can protect, conserve and restore salmon populations in Irish and international waters and how we can inspire action.

“I am delighted to see the excellent research facility here in the Erriff. I am assured that the ongoing scientific research by IFI adds to our understanding of the issues facing salmon and will inform Ireland’s position as part of the EU delegation in discussions which will shortly take place at Nasco — the North Atlantic Salmon Conservation Organisation — on this important topic.”

Anglers are needed as citizen scientists for a new National Salmon Scale Project, says Sean Canney TD, Minister of State with responsibility for the inland fisheries sector.

Minister Canney said: “As we celebrate International Year of the Salmon, this project will help researchers understand the challenges which salmon are facing today.

“The project, which has been initiated by Inland Fisheries Ireland, aims to collect vital information through scales taken from salmon and sea trout which are caught in Irish rivers and lakes and will contribute to international efforts to conserve wild salmon.”

Fish scales record the life history of a salmon, and one scale can reveal a lot about the lifestyle and behaviour of the fish.

Scales can tell scientists what age the fish is, how many winters it spent at sea, how many times it spawned, how slow or fast it grew, what it ate and how long it spent in the river before it went out to sea.

Scales can also reveal the general feeding area where the salmon travelled to in the ocean, whether it went to the Faroe Islands, the Norwegian Sea or all the way to West Greenland. Scales help scientists to understand the biology and ecology of Irish salmon and sea trout.

As part of the project, anglers are asked to take a scale sample from a salmon or sea trout by gently scraping and removing approximately 20 fish scales using a clean knife, then post their samples to Inland Fisheries Ireland (IFI) using the sample envelopes which will be made available to them.

Scales can be removed from both harvested and catch-and-release fish. Sampling of fish for release should be handled carefully and fish should be only briefly removed from the water with every effort made to avoid injury or stress while weight should be estimated.

Information from salmon scales is used in setting conservation limits for Irish rivers. Conservation limits for each river are set based on the proportion of salmon who have spent one winter at sea and those that have spent multiple winters at sea.

The conservation limit for a river represents the number of spawning salmon required to produce the next generation of salmon and this information helps inform angling regulations and management. Information from scales on multi-sea winter salmon entering rivers in spring is also important for managing individual river stocks.

Dr Paddy Gargan, senior research officer at IFI, said: “It is important to have anglers collecting scales as they can provide broad coverage across Ireland and collect scales throughout the fishing season.

“A scale resource which includes many different river systems in Ireland over several years is a great asset from a research perspective as it allows us to examine the factors affecting salmon survival at sea. We can compare how factors, such as climate change, are impacting survival by analysing today’s salmon scales alongside those from many decades ago.”

All scales collected through the National Salmon Scale Project will be added to the National Salmon Scale Archive which is managed by IFI.

The archive, which consists of a dedicated storage facility and associated database, currently holds 19,300 scale samples from a total of 38 rivers representing 152 sampling years. The National Salmon Scale Project aims to increase the scale resource available to scientists for ongoing and future research.

IFI’s head of research and development Dr Cathal Gallagher said: “Ultimately the National Salmon Scale Project will help inform future salmon management policies and activities.

“It is fitting therefore that we are launching this campaign during International Year of the Salmon which aims to raise awareness of what humans can do to ensure salmon and their habitats are conserved and restored against a backdrop of several environmental pressures. This project offers anglers a very tangible and practical way of playing an active role in salmon conservation.”

A new study shows low salmon survival leaving freshwater is an important factor in declining European salmon populations, according to early results from a project examining the early migration phase of salmon smolts (young salmon) from rivers across Europe. Leading salmon scientists from Denmark, Spain, Sweden, UK and Ireland are today attending an important meeting in Dublin, hosted by Inland Fisheries Ireland, to mark International Year of the Salmon. The scientists will discuss some of their new findings from the international SMOLTRACK project, the results of which reveal factors in the known decline of salmon stocks.

The SMOLTRACK Project, which is funded by the North Atlantic Salmon Conservation Organisation (NASCO) / EU, aims to help determine the survival rates of young salmon as they move from rivers into the marine environment. Work commenced in 2017 and early results show that survival during movement from rivers to the sea is lower than expected. While it was already accepted that salmon are impacted by a number of factors when they migrate at sea including the effects of climate change, limited feeding opportunities and sea lice-induced by fish farms, the low survival rate in river systems which is presenting in this research is a new development.

The low survival of smolts in some river systems could be attributed to changes in temperature and flow while predators have also been shown to impact on the numbers entering the sea. The survival of smolts varies by catchment and in a bad year, survival of smolts can be three times lower than in a good year. These results will be published in international journals on completion of the research. 

The international project sees scientists from each participating country tag salmon smolts with miniaturised acoustic and radio transmitter tags in rivers in their own country, and track their migration journey through the lower parts of rivers, estuaries and coastal areas. This study includes populations in Southern Europe which are most vulnerable to climate change. In Ireland, this work is being carried out in the River Erriff, Inland Fisheries Ireland’s National Salmonid Index Catchment (NSIC).

In addition to the activity in Ireland, tagging is being carried out on the River Bush (Northern Ireland), River Tamar (England), River Ulla and River Minho (Spain), River Göta and River Högvadsån (Sweden), River Skjern and River Storaa (Denmark). This information will help scientists to understand the survival rates of salmon smolts during their migrations under varying conditions ranging from cooler climates in Sweden to warmer climate in Spain. Already SMOLTRACK is providing new data on the initial migration of salmon smolts which will inform future management and conservation measures for this iconic species.

Dr William Roche, Senior Research Officer at Inland Fisheries Ireland said: “Understanding and comparing early marine survival of salmon in EU waters is a key output of this project in addition to providing data on smolt run timing and migration behaviour. The project has established a European-wide counting, tagging and tracking system to monitor smolts and will also contribute to understanding of the possible impacts of climate change.”

Dr Cathal Gallagher, Head of Research and Development at Inland Fisheries Ireland said: “We have seen a substantial reduction in the numbers of salmon returning to Irish shores in recent decades. This project is examining what is happening to our young salmon as they migrate to sea and what the international community needs to do to help salmon populations. While this research identifies issues in early mortality of salmon, this part of a salmon’s life cycle is where management actions can be targeted to support the future of these salmon stocks. International Year of the Salmon offers an opportunity to share knowledge across the Northern Hemisphere with a view to inspiring action and collaboration with a positive effect on salmon survival.”

International Year of the Salmon is a joint worldwide initiative of the North Atlantic Salmon Conservation Organisation (NASCO) and the North Pacific Anadromous Fish Commission (NPAFC) alongside other partners across the globe, creating an international framework for collaborative outreach and research. It is hoped that IYS will raise awareness of what humans can do to ensure salmon and their habitats are conserved and restored against a backdrop of several environmental factors.

#Angling - A new project on the River Easkey in Co Sligo which has improved and developed angling access to the wild salmon river between Sligo and Ballina has now been completed.

The project, which was delivered by River Easkey Angling Association, received support from Inland Fisheries Ireland (IFI) via the National Strategy for Angling Development.

Structures such as footbridges, stiles, and ladders were installed along the river, which is located on the Wild Atlantic Way, while walkway routes on the banks of the salmon and trout fishery were also improved.

The work took place upstream of the famous Workhouse Bridge as part of the second phase of this project which initially involved similar works downstream of the bridge last year.

In total, the project has delivered eight new access points to angling, 13 footbridges ranging from three to four metres in length, and five kilometres of improved trail access.

Sean Canney, Minister of State for responsibility for inland fisheries, said on Wednesday (23 January): “I welcome the continuing efforts of Inland Fisheries Ireland in delivering under the National Strategy for Angling Development in partnership and collaboration with local angling clubs and community groups nationwide.

“Inland Fisheries Ireland committed €23,500 in total to support the Easkey project with €10,000 awarded in 2017 and a further €13,500 granted in 2018.

“I also want to congratulate the River Easkey Angling Association on its excellent development ethos. They are a progressive group that helpfully operates an open policy for holders of a State Salmon License with season and day tickets available for access,” he added.

Suzanne Campion, head of business development at IFI, said: “The River Easkey Angling Association has done fantastic work in developing this area as an angling destination. While completing this project and working closely with our project officers, they have given due diligence to everything from financial and environmental governance to biosecurity considerations ensuring the conservation and protection of this wonderful resource.”

Alan Spencer, assistant secretary of the River Easkey Angling Association, expressed the club’s thanks to Inland Fisheries Ireland’s staff for all their help and support during the project, as well as gratitude to landowners who permitted the club and its contractor access to the river through their property.

To track Atlantic salmon movements from river to sea and back, millions of salmon have been tagged over the past 50 years as part of scientific international tagging programmes.

Recently, ICES published a co-operative research report documenting 50 years of marine tag recoveries from Atlantic salmon, and marking 2019’s declaration as International Year the Salmon.

Programmes have included tagging of smolts, migrating out from their freshwater nurseries to the sea and their recaptures in high-seas fisheries off Norway and the Faroes, in coastal fisheries around Greenland and upon return to home waters.

Other studies included tagging of adults caught at sea and their subsequent recaptures in home waters in coastal fisheries and by anglers.

“Tagging and related data efforts are crucial as scientists seek to improve understanding of wild Atlantic salmon distribution and migration at sea and the underlying causes of mortality,” said Niall O'Maoileidigh of the Marine Institute.

“This is particularly important given that, despite initiatives that have mitigated some declines, abundance of the species has continued to drop in the last two decades.”

Tagging has included various types of external ‘floy tags’ focusing in the past 20 years on coded wire tags, less than 2mm in length and delicately implanted into the nose cartilage of fish.

This report not only documents the history of these tagging programmes for posterity but also investigates migration patterns, timings, return rates, their changes and patterns.

“Mass marking techniques still provide basic information on survival rates, exploitation rates and migration in general. However, with current technology e-tagging is becoming far more informative, giving rise to information not only of the ‘when and where’ of tagging-releases and recaptures, but also on the movements, routes, depths and behaviours in-between,” O’Maoileidigh added.

Earlier this week Ireland’s first salmon of 2019 was caught and released on New Year’s Day in Co Donegal.

#Angling - Only hours after 84 Irish rivers were opened to salmon angling on Tuesday 1 January, the first salmon of 2019 was caught and released on the Lackagh River in Co Donegal.

Michael McCann of Templeard, Derry landed the 5lb fish in the Garden Pool on the Lackagh River at 9.25am yesterday using a single barbless hook, before it was released back into the water.

The fish was also the first salmon caught and released during International Year of the Salmon which takes place throughout 2019.

McCann was one of 22 anglers who were fishing on the Lackagh at the time of the catch. The river is not known for producing the first salmon of the angling season — in 2018, the first was recorded on the River Drowes in Leitrim on 30 January while in 2017 it was caught on the Munster Blackwater in Cork on 1 February.

Congratulating McCann on his catch, Dr Ciaran Byrne, CEO of Inland Fisheries Ireland, said: “We are particularly delighted that the first salmon of 2019 was caught and released in a sustainable manner in Donegal in compliance with the 2019 regulations.

“I would urge anglers to step up their conservation efforts and engage in catch and release angling in 2019. The new year coincides with International Year of the Salmon which aims to raise awareness of some of the challenges facing salmon stocks across the Northern hemisphere.

“Salmon populations have plummeted in recent years with the number of salmon returning to Irish shores decreasing by over 70%, which is very concerning.

“We look forward to promoting this global initiative in Ireland which aims to bring people together to share knowledge, raise awareness and take action on how we can ensure the resilience of salmon in Ireland and across the Northern hemisphere.”

The Lackagh River is open to catch and release fishing during the 2019 season. The regulations for the management of the wild salmon and sea trout fishery for 2019 including the list of open, catch and release and closed rivers can be found on the IFI website.
