Inland Fisheries Ireland (IFI) says it is continuing to investigate a fish kill in Co Donegal on Thursday (6 June) in which early indications suggest up to 250 fish may have died.
The pollution incident occurred on a tributary of the Skeoge River in Bridgend, Co Donegal, which flows into a Special Area of Conservation.
Fish mortalities were observed in a 1km stretch of the water, IFI says, with species including juvenile Atlantic salmon, brown trout, European eel and stickleback among the dead specimens found.
Fisheries environmental officers have been on site since early Thursday morning to investigate the incident. A number of samples have been taken from the river to gather evidence of the discharge.
Monitoring and assessment will continue to identify the cause of the fish kill, and the quality of the water, IFI adds.
Donegal County Council is also carrying out its own investigation into the pollution event.
