#FishKill - Galway Bay FM reports on an investigation into a fish kill discovered in Loughrea Lake yesterday 12 May.

Inland Fisheries Ireland staff have attended the scene after being alerted by the public, discovering some 100 dead perch in the water.

However, it is believed the fish died as a result of a natural phenomenon, as no dead fish of any other species was found.

Such mortalities in the wake of the perch spawning season are not uncommon due to the stresses it puts on the fish, leaving them susceptible to infection.

#FishKill - Accidental pollution from a farm in Co Kerry has resulted in a fish kill on a tributary of the Ballyline River.

Inland Fisheries Ireland were contacted by Kerry County Council on Saturday 16 March after being altered by a farmer to a slurry spill on his property in the Kilgarvan area of Ballylongford.

Upon arriving at the farm, IFI officers found one side of the slurry pit wall had collapsed, resulting in a large slurry spill. Two cattle were also injured in the incident and had to be put down. 

The slurry went into a watercourse that eventually flows into the Shannon Estuary at Ballylongford Bay.

The farmer had carried out emergency measures on site attempting to contain the slurry and also trying to minimise the impact to fish and wildlife downstream.

Fisheries officers carried out a visual inspection downstream but as the slurry was still passing there was strong discolouration and so it was impossible to see any dead fish. Samples were taken and sent for analysis immediately.

The situation was monitored over the weekend, and a full walkover of the stream was carried out as the water cleared on Tuesday 19 March.

IFI can confirm that a fish kill took place as a result of the pollution incident, and that 150 brown trout, hundreds of stickleback, one eel and one flounder were recovered. The section of river downstream from the farm to Gortanacooka Bridge was the most heavily impacted.

Currently there is a buildup of organic sediment in the river from the farm to the first bridge in Graffa Bog, which IFI says will not disperse until there is a flood in the river. 

The farm was also inspected on the evening of 19 March and the water within the watercourse was clear. The investigation continues.

#FishKill - Inland Fisheries Ireland (IFI) staff are continuing their investigation into the deaths into some 500 freshwater fish in the River Dodder late last week.

The fish kill is now thought to cover a 2km stretch of the river in the Tallaght area of south Dublin, and species affected include adult and juvenile brown trout, lamprey and stoneloach.

According to the IFI, live fish were recorded immediately upstream and downstream of the affected area.

As previously reported on Afloat.ie, the fisheries body is following a definite line of enquiry regarding the source of the contamination that caused what Redmond O'Hanlon of the Dodder Anglers Group called the worst fish kill he had witnessed "in 30 years".

#InlandWaterways - Reports indicate that as many as 500 freshwater fish of various species have been found dead in the River Dodder in Tallaght, south Dublin.

The fish kill was discovered on Friday evening upstream of the Old Bawn bridge, and according to the Irish Independent, Inland Fisheries Ireland says samples have been taken from the scene - and that a possible source has been identified.

However, the fisheries body refused to comment on speculation that the fish kill was a result of discharge from industrial waste or illegal dumping.

The fish kill covers a 600-metre stretch of the river in the south Dublin suburb.

Speaking to The Irish Times, Redmond O’Hanlon of the Dodder Anglers Group said it is the worst fish kill he has witnessed "in 30 years".

#INLAND WATERWAYS - Fisheries environmental officers at Inland Fisheries Ireland received reports of a fish kill in the Kiltha River in Castlemartyr, Co Cork from anglers late on Saturday 11 August last.

The investigation which initiated early the following morning revealed that many thousands of brown trout fry, parr and adults, salmon fry and parr, brook lamprey, stickleback and stone loach were killed.

The fish kill affected a 5.5km section of the Kiltha River from Mogeely downstream to its confluence with the Dower River.

The Kiltha River is an important salmonid spawning and nursery tributary of the Womanagh River which flows east into the sea at Youghal Harbour. This fish kill is particularly disappointing as the Womanagh River, which is currently closed to salmon angling, had been responding well to management and has seen its fish populations increase over the past several years.

The effects of the pollutant which entered the river were quick-acting, indicating that the pollutant was of a toxic nature.

Inland Fisheries Ireland is awaiting test results of water samples to determine the nature of the pollutant. While this analysis is taking place IFI’s investigation into the cause of the kill is continuing with several potential sources being examined.

The news comes just weeks after reports of fish mortalities along a 9km stretch of the River Vartry in Co Wicklow.

Members of the public are reminded that Inland Fisheries Ireland operates a confidential 24 hour hotline and suspected illegal fishing or pollution can be reported to 1890 347 424 or for easier recall 1890 FISH 24.

#INLAND WATERWAYS - Officials at the Northern Ireland Environment Agency (NIEA) are attempting to find the source of a pollutant that resulted in a fish kill on the Threemilewater river in recent weeks.

The Newtownabbey Times reports that more than 120 trout and salmon parr have been found dead on the short stretch of river between Mossley Mill and Doagh Road in Newtownabbey, Co Antrim.

John Webster of the Threemilewater Conservation and Angling Association speculated that the pollutant may have entered the water from any of a number of pipes that flow into the waterway near the railway line at Mossley Mill.

He described the fish kill as "an absolute diasaster", especially coming as it did at the opening of the fishing season on 1 March.
