#Angling - Inland Fisheries Ireland yesterday (Friday 4 May) responded to reports of a fish kill at The Lough in Cork city centre.

The reports were received from Cork Carp Anglers Club who recorded a number of dead fish at this iconic Cork carp fishery.

Initial investigations by IFI indicate the cause of death to be a fish health issue, with a bacterial or fungal infection suspected of causing the mortalities.

It is estimated that in the region of 200 carp have been infected in this outbreak.

A small number of live fish have been securely transported to a specialist fish health unit to identify the infectious agent.

All dead fish that have been collected are being held in cold storage at an IFI facility pending the outcome of tests to determine the exact cause of death.

Anglers are requested to suspend all fishing activity at the lake until further notice.

Any anglers who have been fishing the venue in the last month are advised to carry out appropriate disinfection of their landing nets, fish mats, footwear and other gear that may have become contaminated, to prevent the spread of the disease to other fisheries.

#FishKill - Irish Water pleaded guilty to the discharge of deleterious matter to the River Vartry one year ago, at a sitting of Bray District Court this past Tuesday (20 February).

The offence related to the accidental discharge of lime from their water treatment facility at Roundwood, Co Wicklow.

Roisin O’Callaghan, fisheries environmental officer with Inland Fisheries Ireland (IFI), told Judge Kennedy that, on 21 February 2017, IFI received a call that there had been an accidental spill of lime at the water treatment plant.

On investigation, O’Callaghan confirmed that the spill had resulted in a fish kill for approximately 500 metres downstream from the discharge.

A series of water samples were taken and analysis confirmed that the lime spill had altered the pH in the receiving water, resulting in the death of approximately 100 fish.

Irish Water co-operated fully with IFI’s investigation and initiated an immediate clean-up of the site.

Eoghan Cole BL, representing Irish Water, stated that following the clean-up, the Environmental Protection Agency had completed a dye survey on the drainage network to confirm that only clean surface water was discharging to the River Vartry.

Judge Kennedy commented on the significance of the River Vartry in supporting Atlantic salmon, sea trout, brown trout and lamprey.

Irish Water were fined €500 with costs and expenses amounting to €6,937.65.

#FishKill - A bio-renewables plant has been fined £1,600 over a fish kill in an important salmon and trout angling catchment in Co Derry over a year ago, according to BBC News.

J&A Renewables was found to have allowed a slurry discharge into the Altagoan River, a tributary of the Moyola River, causing the death of a “significant” number of fish over a two-mile stretch in November 2016, as previously reported on Afloat.ie.

The company, which uses slurry and silage to make biogas for power generation, was also found to be operating its anaerobic digester without a proper waste management licence.

A fine of £1,600 plus compensation costs of £1,800 was handed down by Magherafelt Magistrates Court.

#FishKill - Inland Fisheries Ireland (IFI) has expressed disappointment at the findings of the Environmental Protection Agency (EPA)’s water quality review.

According to the EPA report, published yesterday (Thursday 31 August), the total number of reported fish kills in 2013–2015 was 97 — an increase in fish kills compared to 2007–2009 and 2010–2012.

In several instances of fish kills, the exact cause was unknown and several influences may have played a part.

IFI has cautioned against singling out any particular sector for the standard in water quality across Ireland’s river basins and lakes, backing the EPA’s findings that “multiple factors” are at play.

“There were 31 separate fish kills across the country last year, but just eight of those were directly attributable to agricultural activities,” said IFI chief executive Dr Ciaran Byrne.

“Inland Fisheries Ireland is grateful to the farming community for their continued consideration and vigilance. Good farmyard management can help to prevent accidental runs of polluting substances and protect the local environment.”

In addition to the agricultural-related kills, two fish kills were as a result of municipal works and one by industrial works.

In four instances, the exact cause of the fish kill was difficult to ascertain while 16 incidents of fish kills were as a result of disease and natural causes.

IFI carried out over 22,000 environmental inspections in 2016 across industrial, forestry, engineering, water treatment, farmyards and wind farms sites to help identify any risks and prevent damage to the local aquatic habitat.

“From an ecological and angling tourism perspective, our rivers and lakes are vital national resources,” said Dr Byrne. “It is essential that we protect and conserve these assets and water quality has a significant impact on fisheries habitats and populations.”

#FishKill - A car tyre blocking a sewer led to a major fish kill on the River Tolka in West Dublin this week.

According to TheJournal.ie, as many as 500 fish were killed over a 3km stretch of the waterway between Mulhuddart and Blanchardstown after the blockage caused a manhole cover to overflow into the river.

Local anglers reported the incident to Inland Fisheries Ireland on Tuesday evening (18 July), as RTÉ News reports.

Since then, local angling shop proprietor Derek Talbot has described it as an “absolute disaster” for West Dublin’s angling community.

The Tolka previously suffered an extensive fish kill almost exactly three years ago, affecting thousands of fish downstream from Finglas Road in Glasnevin.

#Angling - A landowner has been convicted of a breach to the Water Pollution Act in Glenamaddy, Co Galway that resulted in a major fish kill.

At a sitting of Tuam District Court, Michael Conneally of Boyounagh, Glenamaddy pleaded guilty to permitting silage effluent to enter the Yellow River, a tributary of the Clare River in Co Galway, on 15 June 2016.

David Harrington, senior fisheries environmental officer with Inland Fisheries Ireland (IFI), gave evidence of tracing the source of the fish kill back to a pipe originating from a silage pit on Conneally’s land.

The pollution incident resulted in damage to fish stock in the Yellow River, which is an important spawning tributary for salmon and trout with the absence of aquatic life noted for a considerable distance downstream, as previously reported on Afloat.ie.

Conneally fully co-operated with officers from IFI and sought to remedy the incident without delay. However, the polluting matter had already impacted the river.

Judge Mary Devins convicted Conneally and fined him €750 with three months to pay, as well as laboratory expenses of €464.94 and legal costs of €600.

IFI chief executive Dr Ciaran Byrne said: “We would appeal to farmers for continued vigilance to help protect our waterways from agricultural pollution.

“At this time of year, silage is in full swing and silage effluent can be a highly toxic substance when it gets into rivers, starving the fish and invertebrate life of oxygen. This incident on the Clare River highlights the large impact one leak can have on our fisheries resource.”

The Clare River is the largest tributary of Lough Corrib, and sees thousands of salmon and trout run the river to spawn every year. It provides a valuable angling facility for local and tourist anglers in the West of Ireland.

There are six different angling clubs along the river who have made significant investment in recent years to help improve the spawning and nursery habitat for salmon and trout. The clubs rely on the responsible environmental stewardship of local farmers to maintain the Clare River as a key angling resource.

Angling in Ireland currently contributes €836 million to the Irish economy annually, supporting upwards of 11,000 jobs.

#FiskKill - Heavy rain over the weekend slowed the investigation into a fish kill on a tributary of an important salmon and trout river for Northern Ireland.

As BBC News reports, a slurry discharge in the Altagoan River near Magherafelt caused the death of a “significant” number of fish over a two-mile stretch, as discovered by local anglers late last week.

The Altagoan flows into the Moyola River, described by the Moyola Angling Club as “one of Northern Ireland’s premier salmon and dollaghan [Lough Neagh trout] rivers”.

Local fishermen say the situation is “completely devastaing” to the popular game fishery, which has had much enhancement work over the last decade.

The news comes just week after a cracked pipe led to a chemical spill and subsequent fish kill in a Co Down river, amid concerns over spikes in pollution and poaching across Northern Ireland.

#FishKill - The fish kill on the Annsborough River in Co Down last weekend was caused by a chemical leak from a cracked pipe, accoridng to BBC News.

And NI Water has offered to restock the salmon and sea trout stream, one popular with local angling enthusiasts, days after the incident at its water treatment plant in the area.

As previously reported on Afloat.ie, some 1,600 fish were killed when the river was polluted by what’s since been confirmed as a polyelectrolyte used in processing water treatment byproducts.

"The severity of this incident is very unusual for our company. We truly regret the outcome and the number of fish that have been killed,” said NI Water in a statement.

#FishKill - Accidental discharge from a water treatment works is to blame for a major fish kill incident on a Co Down river at the weekend, as the Belfast Telegraph reports.

Angling enthusiasts have expressed dismay over the deaths of more than 1,600 fish on a tributary of the Annsborough River that flows into Dundrum Bay near Newcastle, after making the grim discovery on Saturday 8 October.

The Northern Ireland Environment Agency is currently investigating the incident, which NI Water has admitted was caused by an accidental discharge of chemicals into a river known locally for salmon and sea trout.

The Belfast Telegraph has more on the story HERE.

Earlier today Afloat.ie reported on concerns among Northern Irish anglers over spikes in pollution and poaching on the country’s waterways.

#Angling - Pollution and poaching are a growing concern for anglers in the Carlingford and Lough Foyle areas, as Derek Evans reports in his latest Angling Notes for The Irish Times.

New figures from the Loughs Agency reveal a significant raise in pollution, the worst incident of which occurred this past August when hundreds of salmon fry were lost in a fish kill on the River Faughan, according to the Derry Journal.

In addition, the Loughs Agency report informed NI Environment Minister Michelle McIlveen of almost double the number of fishing gear seizures this year compared to 2015, as well as a sharp rise in court actions.
