Investigation launched as thousands of fish killed
An investigation has started into the death of nearly 14,750 fish in a tributary of the Nenagh River in Co Tipperary.
Inland Fisheries Ireland confirmed that a large fish kill had occurred on the Ollatrim River, with dead fish seen over a 5km stretch.
Fisheries officers attended the site at Ballinahemery Bridge, near Ballymackey, Nenagh, after receiving a report last week.
The species affected by the incident included brown trout (1,400), protected species lamprey (10,500), stone loach (805), minnow (1,820), salmon (70), crayfish (70) and stickleback (84).
The investigation to identify the source of the fish kill is continuing with the cause appearing to have been some sort of chemical agent.
