Northern Ireland’s inland waters have seen a third fish kill in as many months after hundreds of dead trout were found in a Co Fermanagh river, as BBC News reports.

The grim discovery in the Kesh River on Wednesday (1 September) comes just days after the Three Mile Water in Co Antrim was struck by its second fish kill incident of this summer.

Ian Grimsley of Kesh and District Angling Club said the incident — which claimed not only brown trout and river trout but juvenile salmon, perch and more — was the worst of its kind he had witnessed in the area in 40 years.

And like last week’s fish kill in Newtownabbey, he fears “it’ll take years to bring it back again”.

The Northern Ireland Environment Agency (NIEA) has launched an investigation, with the origin of the river pollutant as yet unknown. BBC News has more on the story HERE.

Co Antrim’s Three Mile Water has been afflicted by a second fish kill this summer — and a local angling group says it could take years to recover.

The Belfast Telegraph reports on the incident which was discovered on the river at Monkstown on Friday afternoon (27 August).

Trout, eels and even flounder that swim upstream from Belfast Lough are among the species affected in what the Three Mile Water Conservation and Angling Association has branded a “major fish kill”.

It comes less than three months after hundreds of trout were believed to have been killed on the same river in an incident the cause of which has not been identified.

Inland Fisheries Ireland (IFI) says it is investigating a serious fish kill incident at Barnagrow Lake near Shercock in Co Cavan, within the Annalee River and Upper Erne catchment area.

Environmental and fisheries officers from the North-Western River Basin District were alerted to the incident by a call from a member of the public this past Tuesday (27 July).

And the State agency responsible for the protection and conservation of freshwater fish and habitats estimates that there could be in excess of 5,000 fish mortalities, including species such as bream, roach, perch and pike.

Fish samples have been taken from the lake and removed for further analysis. Initial investigations indicate that a severe algal bloom, combined with high water temperatures and low oxygen levels recorded in Barnagrow Lake, are the likely causes of the incident.

Dr Milton Matthews, director of the North-Western River Basin District with IFI, said: “Unfortunately, this is a very significant fish kill affecting several year classes of coarse fish and is the largest reported fish kill nationally to date in 2021.”

He added: “During the recent heatwave, very high water temperatures were noted at several angling locations, with temperatures of over 26 degrees [Celsius] for example recorded in Lough Sheelin, Co Cavan.

“In the days preceding the fish kill at Barnagrow Lake, a severe algal bloom was noted by Inland Fisheries Ireland staff, which together with very high water temperatures recorded locally, which were 22 degrees [Celsius], likely resulted in this serious fish kill event due to reduced oxygen levels in the water.”

Authorities in Northern Ireland are investigating a fish kill that’s claimed hundreds of trout in a stretch of the Three Mile Water in Co Antrim.

According to BBC News, many of the dead trout “were sizeable fish of spawning age”.

Officials at the Department of Agriculture, Environment and Rural Affairs (Daera) have not identified the origin of the alleged pollution incident.

It is also understood that water levels in the river have been low following the recent warm and dry weather spell. BBC News has more on the story HERE.

In other NI angling news, a Portadown man has been fined £1,000 after admitting a series of offences at the north lake in Craigavon, as ArmaghI reports.

At a recent sitting of Craigavon Magistrates’ Court, Gareth McLoughlin was convicted of fishing without a licence and permit, fishing on a closed fishery, obstruction and failing to provide his name and address to fisheries officers in an incident on 12 January 2020.

The court heard McLoughlin was observed angling with four rods at a lake which was at the time closed to angling, and fled the scene when challenged.

It could be years before a river at the centre of a recent suspected agricultural pollution incident in Co Tyrone is fully recovered, as the Belfast Telegraph reports.

The fish kill in the Aughlish River discovered over the May Bank Holiday weekend covered a five-mile stretch of the Northern Ireland waterway between Dromore and Fintona, with reports of thousands of dead brown trout and young salmon to the Loughs Agency.

Omagh Anglers secretary Terry Smithson said the incident was “devastating”. He estimated that five years of salmon stock had been lost and it could be as many as three years before the waterway recovers.

Northern Ireland’s Agriculture Minister has confirmed that a fish kill in a tributary of the River Moyola last week was caused by a spillage of 30,000 gallons of slurry, as BBC News reports.

The incident on the Grange River in Co Derry on Thursday 21 May affected a significant stretch of water near the village of Desertmartin, according to a local angling club.

It’s understood that the spillage originated from an over-ground slurry tank, but the circumstances are still being investigated.

The incident comes just weeks after anglers in Co Armagh expressed anger at the killing of more than 1,000 wild brown trout by pollution in the Glenavy River.

Anglers in Co Antrim have expressed their anger after more than 1,000 wild brown trout were killed in a pollution incident at the weekend.

As the Belfast Telegraph reports, members of the Glenavy Conservation and District Angling Club spotted a number of distressed fish gasping for air in the Glenavy River on Friday (8 May).

An initial count of some 500 dead fish was later doubled to over 1,000, linked to what the angling club suggests was a pollution incident close to the Gobranna Road in Glenavy.

“Hundreds, possibly thousands” of other, smaller fish such as stone loach were also “wiped out” in the fish kill, says club chairman Anthony McCormack.

It’s understood that hundreds if not thousands of fish including brown trout, juvenile salmon and bream may be affected by a fish kill on a tributary of the Bandon River in Co Cork.

Inland Fisheries Ireland (IFI) says it is investigating the fish kill on a minor tributary of the Bandon River in Co Cork in the stream south of Dunmanway near Curraghalicky Lake.

IFI says it attended the site on Monday evening (26 August) following a report from a local angler — and initial investigations point to “a significant algal bloom” as the cause.

“Efforts are ongoing to assess the extent of the fish kill and an aerial survey of the lake is underway,” IFI adds.

“Cork County Council has taken water samples from the lake and river and is liaising with Inland Fisheries Ireland in their investigation.”

Inland Fisheries Ireland (IFI) says it has confirmed a significant fish kill on the Royal Canal in Kilcock, Co Kildare earlier this week.

A report was received on Monday 1 July from Waterways Ireland of the fish kill, which has claimed some 300 fish of various species including roach, rudd, bream and pike.

The investigation, which commenced immediately and remains ongoing, has identified agricultural discharge to a River Ryewater feeder that enters the canal at Kilcock.

IFI says work is now ongoing to ensure that there is no further polluting discharge to the system from this location.

It has also has issued a fresh appeal to farmers to remain vigilant in avoiding water pollution during the summer months when harvesting silage and spreading slurry.

Silage effluent is a significant pollutant and if allowed to enter a waterway can potentially lead to fish death and habitat degradation.

IFI has a confidential hotline number at 1890 34 74 24 or 1890 FISH 24 for the public to report incidents of water pollution, fish kills and illegal fishing. For more visit fisheriesireland.ie.

#FishKill - Inland Fisheries Ireland (IFI) prosecuted Irish Water yesterday (Tuesday 5 February) at Ballina District Court for the discharge of a harmful substance into the Ballycorrigan River on 17 May last year, causing a fish kill.

Among the fish mortalities were 100 brown trout of different age groups, three juvenile salmon and one stone loach which were killed when a cleaning substance was discharged into the river.

Judge Patrick Durcan heard evidence from Michael Fitzsimons, a senior fisheries environmental officer with IFI, that a detailed investigation was carried out following a pollution report received from the general public.

It found that the fish kill was caused by a combination of effluents arising from an uncontrolled maintenance event from Irish Water’s Ballina/Killaloe wastewater treatment plant.

Irish Water entered a guilty plea. Judge Durcan directed Irish Water to pay IFI’s legal costs of €2,290 and fined the body €2,500.

Judge Durcan stated that Irish Water did not take into consideration the environment and conditions when discharging into the river and that Ireland’s rivers are its most important natural resource.

He said that while these resources are maintained under the vigilance of Inland IFI, Irish Water needs to be vigilant, too.

Amanda Mooney, director of the Shannon River Basin District with IFI, said: “Irish Water co-operated fully with Inland Fisheries Ireland’s investigation and updated its cleaning protocols for the use of chemicals in treatment plants nationwide with more appropriate methods now in use as a direct result of this incident.

“Our fisheries resource is an extremely valuable asset, both from a recreational and economic perspective and it is crucial that we continue to protect and conserve it for future generations to enjoy.”
