An investigation has been launched following a “significant” fish kill involving around 260 fish on the Crana River.

Inland Fisheries Ireland (IFI) and statutory partners said they are now following a line of inquiry regarding the fish kill that took place on the Crana River in County Donegal.

It is estimated that approximately 260 juvenile salmon and brown trout have died.

Fish mortalities were observed over a 350m stretch of the river.

Inland Fisheries Ireland with support from Donegal County Council and the River Basin Management Services, have been on the ground investigating the issue.

Water and fish samples have been taken from the river and water samples have been sent for analysis.

An interagency group met on Saturday, August 29 and again on Monday, August 31 led by IFI, to discuss the fish kill.

As a result of the progress made, a line of enquiry has been established.

A spokesperson for IFI said, “IFI has been working with statutory bodies in line with the new national interagency protocol for investigating significant fish kills and is the lead agency on this case.

“The interagency group was convened under the protocol to enable rapid coordination during the initial response to the incident. 

“As a result of the progress made, a line of enquiry has been established, and the group has completed its role. 

“The investigation now moves into the next phase under the lead of IFI, working closely with relevant agencies.”

Buncrana Councillor Joy Beard was alerted to the incident by Buncrana Angling Association.

Following contact from the Association, Cllr Beard reported the matter to IFI and officers attended the scene 30 minutes after it was reported.

Cllr Beard said, “I want to sincerely thank the Buncrana Angling Association for bringing this very serious incident to my attention and for the work they do in monitoring and protecting the Crana River.

“Local anglers are often the first to spot when something is wrong, and their knowledge of the river is invaluable.

“These fish are the future of the river, and this loss must be treated with the seriousness it deserves.

“We now need to find out exactly what happened, as a matter of urgency.

“Samples are being sent for testing, and the public deserves a full, clear account of the outcome, what caused this fish kill, how far any impact extends and what action will follow.

“This cannot simply become another incident that is noted and forgotten about.

“If this was caused by pollution or another preventable failure, there must be accountability.

“More importantly, firm measures must be put in place to ensure this never happens again,” said Cllr Beard.

She added that the Crana River is a “hugely important part of local natural heritage.”

“It is valued by residents, anglers and visitors alike, and we all have a responsibility to protect it for future generations,” she said.

Cllr Beard added she will seek a full update from Inland Fisheries Ireland including details of any action proposed to prevent a recurrence. 

IFI continues to urge the public to report instances of fish kills, water pollution, habitat destruction, or illegal fishing to its confidential 24/7 number, 0818 34 74 24.
