Hefty EU fines could be imposed on Cork County Council which hasn’t the money to build a ‘fish path’ for migrating salmon. A hands-on approach to dealing with migrating salmon may be needed again this year it is feared. The salmon need help getting over a weir because the fish path has been destroyed.
It’s estimated it will cost in the region of €2m to purchase land and build a new fish path at the River Blackwater weir in Fermoy town.
The council is writing to the Department of Communications, Energy and Natural Resources seeking the €2m needed.
It also has to cap the weir and put in protective boulders to prevent it from again being damaged by trees which were swept downriver in previous floods. The council has enough money to do that, but not buy land and install the fish path.
The issue was raised at a meeting of the council’s Northern Division in Mallow by Fermoy-based Cllr Noel McCarthy. He said last October people, waded into the river to physically pick up salmon and take them to the upstream side of the weir.
Cllr McCarthy said it was believed that fish which weren’t picked up died: “I’ve met several people who are very concerned that this will happen again this year. We need to speed up the process and make sure there are no more delays in getting this work done. It’s totally unacceptable.” “We were told at one stage that we could face fines from the EU if this work isn’t done. We were also told originally that Lagan (contractors) would do the work as part the flood relief scheme,” said Cllr Frank O’Flynn who added that he knows a landowner who is anxious to sell the land needed for the fish path.
Council officials said they are in negotiation with a landowner and their legal department is progressing the transfer. However, they admit that they don’t have the money to pay for this part of the project and are in behind the scenes negotiations with the Department of Communications, Energy and Natural Resources.
“The structure of the weir is compromised. Capping must be done and their funding in place for that. This work could be progressed in the coming year,” one council official said. It had been hoped that capping would be undertaken in conjunction with the building of the fish path.
But assistant county manager James Fogarty said this couldn’t happen.
Councillors then agreed to write to the Department of Communications, Energy and Natural Resources asking it to immediately release the €2m for the project.

New research finds salmon farming contributes to sea lice infestation on sea trout as valuable stocks decline
|Sea Liced Trout|
Monday, 9th January 2017: The Board of Inland Fisheries Ireland has welcomed new research by scientists from Inland Fisheries Ireland and Argyll Fisheries Trust (Scotland) which found that sea trout carry significantly higher levels of sea lice infestation closer to marine salmon farms. Researchers examined sea lice levels over 25 years from more than 20,000 sea trout. The sea trout were sampled from 94 separate river and lake systems in Ireland and Scotland at varying distances from salmon farms.
The research revealed that sea trout captured closer to salmon farms had significantly higher levels of lice infestation and were found to be of reduced weight. Sea trout are known to remain for extended periods in near-coastal waters where the majority of salmon farms are located. This fish is therefore particularly vulnerable to sea lice impact, having the potential to encounter lice of farm origin throughout much of its marine life.
The effect of the increased lice infestation was most evident in years of less rainfall, when a sea trout of average length (180mm) caught within 10 kilometres of a farm could weigh up to 10g less than fish of similar length caught more than 40 kilometres from a farm. The study covered the entire coasts of West Ireland and Scotland and accounted for variability in temperature and rainfall.
The research article entitled ‘Aquaculture and environmental drivers of salmon lice infestation and body condition in sea trout’ was authored by Dr. Samuel Shephard and Dr. Paddy Gargan of Inland Fisheries Ireland alongside Craig MacIntyre of the Argyll Fisheries Trust. It was published in the international journal Aquaculture Environment Interactions in October.
Studies have shown that the impact of sea lice in farmed areas on sea trout has been substantial with increased mortality, reduced body condition and a changed migratory behavior reported. Heavily liced sea trout return to freshwater prematurely to rid themselves of lice and exhibit very poor marine growth and greatly reduced marine survival. In fact, the most heavily lice infested sea trout die at sea. Rod catch data from 18 Connemara fisheries from 1974 to 2014 show a collapse in rod catch over the 1989/1990 period (see Figure 1). This collapse has been linked to lice infestation from salmon farms while recovery of sea trout rod catches to pre collapse levels has not occurred.
Sea trout offer significant angling value while traditionally the species was abundant on the west coast of Ireland. Angling is worth €836 million to the Irish economy every year and supports upwards of 11,000 jobs, often in rural and peripheral communities. Inland Fisheries Ireland carries out research across fish populations, their habitats and the ecosystem with a view to informing the protection and conservation of this precious resource.
Dr. Paddy Gargan, Senior Research Officer at Inland Fisheries Ireland and one of the report authors, said: “”While there had been some improvement in sea lice control in recent years, lice control on salmon farms was still not sufficient in certain west of Ireland bays during the spring migration period for sea trout to avoid heavy lice infestation and increased marine mortality. More effort is required to ensure lice levels on salmon farms are adequately controlled at this critical period when sea trout leave freshwater and enter the sea.”
Dr. Cathal Gallagher, Head of Research and Development at Inland Fisheries Ireland said: “The finding that salmon farming is responsible for increased sea lice infestation and for significantly reduced body condition in sea trout may have implications for current lice control management strategies. This research will inform coastal zone planning of aquaculture in the future and contribute towards the avoidance of potential impact on sea trout stocks.
Inland Fisheries Ireland is committed to protecting and conserving our fish populations and this research is crucial in managing the sea trout species in Ireland. This country is known as a unique angling destination as a result of its indigenous wild fish species and beautiful scenery. Continued investment in research is necessary to ensure the conservation and protection of our fisheries resource.”
